Corvette Quarterly’s 1999 Jay Leno Interview

Jay Leno Finally Gets A Corvette!

Dateline: 5.4.22 (Corvette Quarterly interview below) – Jay Leno is arguably more popular today within the car community than he ever was when he was the host of The Tonight Show for nineteen years. Jay appears to be having more fun doing his Jay Leno’s Garage programs than he ever was when hosting The Tonight Show. Not that The Tonight Show was a drag, but you can clearly see that cars, motorcycles, and machines are his first passion. Continue reading “Corvette Quarterly’s 1999 Jay Leno Interview”

Corvette Chiefs, Pt. 4 of 5 – Tom Wallace, Racer C6 Chief Engineer

Former race car driver, Tom Wallace takes the helm as the new Corvette Chief of Engineering

Dateline: 11-5-20 – During Corvette’s early years, as a result of his racing at Le Mans, Zora Arkus-Duntov got the lion’s share of media attention. Credit also goes to three-time Indy 500 winner and automotive engineer Mauri Rose who helped develop the first Corvette chassis on the shop floor as they were being hand-built in Flint, Michigan. Rose and Duntov were friends but Rose wasn’t impressed with Duntov’s driving and used to say, “Zora couldn’t drive a nail with a hammer.” But by the late 1950s, Duntov was the face of Corvette racing.

We have pointed out that Duntov’s successor, Dave McLellan owned and appreciated sports cars and that Dave Hill raced a Lotus Super 7 in SCCA competition. What most Corvette fans don’t know is that while Tom Wallace had the shortest tenure of all of the Corvette chiefs (2 years and 10 months), he raced SCCA A/Sedan class cars in the early ‘70s and was professionally racing IMSA cars in the late ‘70s and early ‘80s. Wallace raced the 24 Hours of Daytona, the 12 Hours of Sebring, and won at Talladega. Why didn’t Wallace continue professional racing? Because it was interfering with his day job at Buick.

Wallace was a typical car-crazy kid growing up in the ‘50s and ‘60s. His Dad had an Opel Cadet that he kept running with help from a parts donor car. Before Wallace had his driver’s license, he bought a ’55 Chevy, replaced the stock 3-speed transmission with a 4-speed, rebuilt the engine, and added dual quads. After getting his license, he had the quickest car in high school and rarely lost a drag race.

Thanks to his excellent grades, Wallace went to General Motors Institute after securing a sponsor to become an automotive engineer. Wallace wanted to get into Chevrolet, but there were no openings, so he opted for Buick. One of his first projects was the design and development of the Exhaust Gas Recirculation (EGR) valve that siphons off a small amount of exhaust gas and returns it back into the intake charge. This results in lower nitrogen oxide (NOx) emissions.

Wallace graduated in 1970 just as the muscle car era peaked and was ending. Performance was being phased out and emissions, fuel mileage, and safety were Detroit’s new mission. Lloyd Reuss, Buick’s chief engineer was aware of Wallace’s interest in racing and asked him to research adding a turbocharger to their old V6 engine. Wallace’s reported that it could be done and Reuss instructed him to install a turbo on a Buick Century to pace the 1976 Indy 500. As part of a three-man team, Wallace was the engineman, the others did the suspension and brakes. In total Wallace produced six Indy 500 pace cars. Wallace’s turbo Buick V6 project eventually lead to the Buick Grand National, Turbo-T, T-Type, and the frightful GNX series cars that ran from 1982 to 1987.

Wallace enjoyed engineering and racing, but he knew that if he was to rise up in the ranks in GM, he needed to curtail his racing and get more education. In the early ‘80s Wallace got his Masters in Business at Stanford and over the next twenty years had a variety of chief positions with Buick, Olds, Cadillac, and Chevrolet groups. When GM started its Vehicle Line Engineer (VLE) management structure, managers were in charge of everything from design-to-production, sales, and service. Wallace ran the Trail Blazer, Envoy, Bravada, Saab 9-7, Colorado/Canyon pickups, and the Hummer H3 lines.

Dave Hill was the VLE of Performance Car that included Corvette, Cadillac XLR, Saturn Sky, Pontiac Solstice, Opel GT. One day during a group vehicle-program review meeting with Bob Lutz; Wallace heard Hill outlining the Z06 with 505-horsepower and a dry-sump oil system, he said to himself, “What the!” Wallace said to Lutz, “My goodness, this is unbelievable. Do you know what Dave is about to do?” Wallace said that some of the VLEs had no idea what Hill was talking about. When Wallace expressed real concern about selling 505-horsepower cars to novice customers, it was explained to him that only select dealers get Z06s. These dealers understand performance and coach customers to have respect for the car and help get them into a driver’s school.

Late in 2005 Wallace got the surprise of his career. After a VLE meeting, Lutz told Wallace that Hill was retiring on January 1 and that he wanted him to take the position of VLE and Chief Engineer for Corvette. Wallace was stunned and fully aware that he was inheriting a great team with Tadge Juechter as his lead engineer. But unforeseen circumstances would make this a short-lived position – only two years and ten months.

When Wallace took over the Corvette program, the C6 ZR1 was a concept on paper and was deemed too expensive. Wallace and his team worked out the cost, got the project approved, and started the ZR1’s development. It wasn’t long before rumors of a super Vette surfaced with names such as “Blue Devil” and “SS”. Then someone inside GM posted a photo of a development ZR1 as it was being shipped to Germany for testing. The Corvette world knew for sure when a cell phone video was posted of a disguised Corvette with the unmistakable sound of a supercharged engine. WOW, a supercharged Corvette!

When the ZR1 was released to the press in late 2007, Wallace explained, “We want to push the technology envelope into the supercar realm. We want a Corvette that can take on any production car in the world.” While Corvette fans were feasting, GM was heading for bankruptcy. Corvettes had a history of platforms running too long. Hill said that the planned six-year duration might even be too long. Wallace and his team started work on the C7 in April 2006. As things got worse for GM, it was discovered that the only full-size trucks and Corvettes were moneymakers. Regardless, future plans had to be stopped.

In October Lutz informed Wallace that the board of directors did not approve funding for the C7, he would have to proceed with paint and decals for the foreseeable future. Also, to preserve cash, top-level executives were offered early retirement to reduce headcount. For a car guy/racer, babysitting the Corvette was not how Wallace wanted to end his GM career, so he retired on November 1, 2008.

Wallace didn’t get to do as much with the Corvette as he wanted, but he did several things that made a difference. He knew that it would be very beneficial for his engineers to get track training at the National Corvette Museum’s and to talk with customers about what they like, don’t like, and want for future Corvettes. As Wallace had expressed concerns over selling powerful Corvettes, included in the price of the ZR1 was high-performance driver training. And with his racing background, Wallace was the perfect lead engineer to work with Pratt & Miller on issues with their C6.R cars. This intense relationship caused more racecar to be built into the C7. While Wallace wasn’t able to usher in the C7, his efforts set up the program for the capable hands of Tadge Juechter. – Scott

Corvette Chiefs, Pt 3 Dave Hill

Dave Hill, Cadillac-Man Saves the C5 Corvette

Dateline: 8-11-20 – This story was originally published in the now-defunct Vette magazine, August 2019 issue. Story, Illustrations & Graphics by K. Scott Teeters) On November 18, 1992 when it was announced that Cadillac Engineering Program Manager David C. “Dave” Hill would become the new Corvette Chief of Engineering, the Corvette community asked, “Why is a Cadillac man taking over the Corvette and what can he bring to the brand?” Hill was the right man for the job, at the right time, and he brought a lot!

In the early ‘90s GM was in financial trouble. The company had lost its way in the ‘80s and in 1989 when Jim Perkins came back from Toyota to become the general manager for Chevrolet, he said he didn’t recognize the place. Moral was low and infighting was rampant. To stop the financial hemorrhaging, every car line was being looked at, and once again, Corvette was on the chopping block.

Thanks to Dave McLellan, the C5 was in the planning stage but only “on paper”. Perkins was Corvette’s “corporate angel”. He argued with GM brass that “Corvette” was one of the best-known automotive names in the world. He told them, “… if you don’t have enough confidence to trust my judgment that we can make money on this car, then I shouldn’t be here.” Perkins won the argument, but with McLellan ready to take early retirement, he needed a new Corvette chief with the know-how for profitability, performance, and quality.

Hill graduated in 1965 from Michigan Technology University with a degree in engineering and went right to work for Cadillac in their engine power development lab. From there, Hill worked his way through many departments. In 1970 he earned his Masters Degree in Engineering from the University of Michigan. Through the ‘70s and ‘80s at Cadillac, Hill was a Senior Project Engineer; Staff Project Engineer; Body and Chassis General Supervisor; Development, Emissions, and Transmission Staff Engineer; and Chief Engineer for the Allante, DeVille, and Concours models. In May 1992 Hill was promoted to Engineering Program Manager for Cadillac. Hill was deeply versed in GM’s premiere car line.

During Hill’s tenure, Cadillacs weren’t the performance cars they are today, but don’t conclude that Hill was into cushy Caddys; he was into sports cars and racing. Hill owned a 1948 MGTB, a 1970 350/350 Corvette Coupe, and from 1968 to 1972 he raced a Lotus Super 7 in SCCA competition.

Like McLellan, Hill had two objectives; first, keep the C4 fresh, and second, design and develop a totally new Corvette. Sales for 1991-to-1996 Corvettes averaged around 20,000 units; a big drop from 1984 when 51,547 Corvettes were sold. Everyone knew the C4 needed to be replaced. From ’93 to ’96 Hill and his team made small improvements and special editions to keep things interesting. In 1993 the 40th Anniversary Package was offered. The ’93 ZR-1 got a power boost from 375-to-405-horsepower. In 1995 the Indy 500 Pace Car Replica, was limited to 527 units. The 1996 lineup had two special editions; the Collector Edition (5,412 units built) and the Grand Sport (1,000 units built; 810 coupes and 190 convertibles).

The transition from the C4 to the C5 Corvette was the most radical of all generational transitions. Typically, when we think “radical,” we think “mid-engine”, “double-overhead-cam” or “turbocharging”. The C5 wasn’t any of that; it was better. In one fell swoop, the basic Corvette had the following; a hydro-formed perimeter frame with a wishbone backbone center spine, an all-new all-aluminum fuel-injected engine (the LS1), connecting the engine and new transaxle was a torque tube; the suspension and brakes were mostly aluminum, slim and lightweight; and an all-new slippery body and lush interior. The entire structure of the car was locked in together with each component designed as a stress-member and was designed to be a convertible. The design was so efficient it had over 1200 fewer parts. This was a Corvette like no previous model had ever been. It was the most radical Corvette to date and the basic structure concept is still used in the C7. The mid-engine C8 will be here soon and if Chevrolet decides to offer front and rear-engine configurations, a C9 will likely use the C5/C6/C7 concept, possibly in carbon fiber.

Sales of the 1997 Corvette didn’t look good, coming in at 9,752. It wasn’t that buyers didn’t like the new car, Corvette plant manager Wil Cooksey made sure that as cars were being built, all problems and process issues were solved and implemented. In 1998 the convertible was released and sales hit 31,084; the best since 1987. C5 sales never went below 30,000 and the best year was 2002 with 35,767; the best year since 1986. Customers were very happy with their C5s with its vastly improved structure that allowed the suspension to be calibrated like never before.

When the C5 was still on the drawing board, a “Billy Bob” strippo model was considered but not explored. Not long after the C5 was released, that concept was flushed out and the result was the ’99 Hardtop model. There wasn’t much of a savings as the Hardtop was only $394 less than the coupe. Sales only hit 4,031 in ’99 and 2,090 in ’00. But engineers learned something interesting. By bolting on and bonding the hardtop, the overall structure was 12-percent stiffer. This was that “something extra” that a performance model could use. The C5 Z06 was genius. With the more powerful 385-horsepower LS6, upgraded brakes, suspension, wheels and tires, a new Corvette legend was forged.

Hill had another ace up his sleeve that brought racing glory to Corvette and impacted the C6. In the fall of 1998, a factory-backed racing team was approved and the cars were christened, “C5-R”. Racecar builders Pratt & Miller were contracted to build the race cars. Hill used Pratt & Miller as his defacto racing engineering team. The Corvette Racing Team became world-class champions, won 1st and 2nd at Le Mans in 2001, 2002, and 2004, as well as every race in 2004!

By 1999 Hill’s engineers informed him that they had done everything they could with the C5 platform. To take the car to the next level, they would have to start the C6. While the C5 and C6 structure is similar, the C6 is all-new; with no important carryover parts. But what no one was expecting was that the Z06 would get a 100-horsepower bump, plus have an aluminum frame. No one was asking for this, but that’s what they got. The C6 Z06 was the most brutish Corvette ever offered.

Hill once said, “My favorite Corvette is the next one.” Mr. Cadillac insisted on three key things; state of the art performance and technology; passionate design; and tremendous value. In an interview with c6registry.com, Hill said, “Being involved with Corvette brings out the best in all of us who have the privilege of working on it. It represents the best that GM has to offer; along with the best America has to offer. The Corvette is very personal. We’re not talking about transportation here; we’re talking about a product that changes someone’s lifestyle, and that causes us to be enthusiastic about our duty.” Hill retired on January 1, 2006, and was inducted into the National Corvette Museum’s Hall of Fame in 2006. – Scott

Corvette Chiefs, Pt. 2 of 5 – Dave McLellan

Dave McLellan, Heir to Duntov’s Engineering Throne

(Dateline: 7-3-20 – This story was originally published in the now-defunct Vette magazine, July 2019 issue. Story, Illustrations & Graphics by K. Scott Teeters) – When Dave McLellan took over as Corvette’s new chief engineer on January 1, 1975, it was a whole new world. The prevailing trends went from performance cars to safer cars with reduced emissions. Not even Duntov could have made a difference in the ‘70s. But as performance went down, Corvette sales went way up! The sales department was happy, but the Corvette was really getting old. Dave McLellan was an unknown to the Corvette community and many wondered what he would bring to the brand. It turned out; he brought a lot!

McLellan was a car guy. He rebuilt his family’s Frazer and entered the Fisher Body Craftsmen’s Guild Model Contest. Upon graduation from Wayne State University in Detroit with a degree in mechanical engineering, GM hired Hill on July 1, 1959. Thought the ‘60s Hill worked at the Milford Proving Ground on noise and acoustics issues with GM tank treads, Buick brakes, and tuned resonators for mufflers. Hill was also going to night school to get his Master’s Degree in engineering mechanics. In 1967 Hill was part of the group that planned and operated the 67-acre Black Lake where ride, handling, and crashworthiness tests are performed.

Chevrolet engineering brought in Hill to work on the 1970-1/2 Camaro and Z28. Hill wanted to move into management so he took a yearlong sabbatical and attended MIT Alfred. P. Sloan School of Management. The school emphasizes innovation in practice and research. In July 1974 Hill was Zora Arkus-Duntov’s part-time assistant, training for taking over the position in 1975.

While Hill didn’t have Duntov’s racing experience, he owned several Porsches and understood racing sports cars. As Duntov was leaving, he told Hill, “Dave, you must do mid-engine Corvette.” Little did they know that it would finally happen forty-five years later.

When Duntov took control of Corvette engineering in 1956, he had to boost sales and make the Corvette a performance car and a capable racecar. When Hill took control, Corvettes were never selling better, but the platform design was nearly fifteen-years-old. Hill had to keep the car fresh, hit the new requirements, and maintain performance; all with a limited budget.

Management figured that the Corvette had a captive audience, so they didn’t have to spend money to change anything. Fortunately, that lame notion was overruled. The 1978 glass fastback and the 1980 front and rear bumper covers were excellent updates. Another major issue was quality control. The St. Louis assembly plant made three other cars and often workers were unfamiliar with the specialties of the Corvette. This issue didn’t get fixed until the plant was moved to the Corvette-only Bowling Green facility.

McLellan knew that the C3 needed to be replaced, as the chassis was designed around 1960! For a brief period, it looked like the mid-engine Aerovette would become the C4, but Chevrolet decided to abandon all mid-engine programs. The all-new C4 began to take shape in Jerry Palmer’s Chevrolet Studio Three in 1978. When the C4 debuted in December 1982, it received rave reviews, despite the fact that suspension engineers later admitted that they over-did-it with the stiff suspension. By 1985 the suspension was softened and the 150-mph Corvette won Car and Driver’s “Fastest Car in America” award and began the total domination of Corvettes in the SCCA Escort Showroom Stock racing series from 1985-to-1987. Porsche bought a Corvette to take apart to find why the car was unbeatable. By the end of 1987, SCCA kicked out all of the Corvettes for being too fast! McLellan followed up with the Corvette Challenge factory-build racecars.

McLellan’s personal style was more suited to the intricacies of modern electronic computer-controlled performance cars than Duntov’s. Where Duntov’s enthusiasm was effervescent, McLellan was laid-back, approachable, but not shy with the automotive press. After the successful rollout of the C4, McLellan took on four very serious performance projects for the Corvette; The Callaway Twin Turbo option, the ZR-1 performance model, the LT-5 Lotus/Mercury Marine performance engine, and the mid-engine CERV-III. Let’s look at all four projects.

“Supercars” were the rage and by 1985 Porsche had their 959 and Ferrari was about to unleash their F40. To have something to offer while McLellan was starting his ZR-1 project, a deal was made with Reeves Callaway to build brand-new Corvettes with a Callaway Twin Turbo package. The cars had 345-horsepower (stock Corvettes had 240) and from 1987-to-1991 RPO B2K was the only non-installed official RPO Corvette option ever offered.

The ZR-1 super-Vette had two components. The first was its Lotus-engineered, all-aluminum, double-overhead-cam engine built by Mercury Marine. McLellan’s engineers set down the size parameters and horsepower objective; Lotus did the rest. McLellan turned to the best manufacturer of all-aluminum, performance marine engines in the country, Mercury marine. The end result was the beautiful jewel-like LT-5, an engine that is still respected today. The second component was the widening of the ZR-1’s body to cover the enormous P315/35ZR17 rear tires and beef up the car’s drivetrain and suspension.

The 1990 CERV-III Corvette was McLellan’s vision of Duntov’s mid-engine Corvette, with electronic steroids. The car had a carbon fiber Lotus-style backbone chassis, four-wheel steering, active suspension, a transverse, 650-horsepower twin-turbocharged LT-5 ZR-1 engine and a dry-sump oil system, and a four-speed transaxle. This was the final design that started out as the Indy Corvette in 1986 and had a top speed of 225-mph. And lastly, the CERV-III was designed to be manufactured.

When McLellan was part of the 1992 “Decision Makers” three-man internal Chevrolet design group, gathered to evaluate the direction of the C5, McLellan chose the CERV-III concept over the front-engine “Momentum Architecture” and the stiffer/lighter restyled C4. But the CERV-III was deemed too expensive for the market. The “Momentum Architecture” with its backbone structure, a transaxle, and an all-aluminum engine with design elements from the LT-5, lives on today in the C7.

McLellan oversaw the three-year, 1990-to-1992 mid-cycle refresh. The process started in 1990 with an all-new dash; 1991 saw new front and rear bumper covers; and in 1992 the 245-horsepower L98 was replaced with the 300-horsepower LT1.

In 1990 McLellan won the Society of Automotive Engineers’ Edward N. Cole Award for Automotive Engineering Innovation. In 1991 GM was offering early retirement packages, allowing 53-year old employees to receive the same benefits as those retiring at 62. McLellan took the offer and stayed on as a consultant while GM looked for a suitable replacement. McLellan was fortunate enough to be in his consulting position on July 2, 1992, when he was on hand to see the one-millionth Corvette roll off the Bowling Green assembly line. What a thrill for a car that McLellan had given so much to and a car that was so often on the line for its survival.

Finally, on November 18, 1992, the new chief of Corvette engineering was Dave Hill. Since then, McLellan has been a much sought after automotive consultant, he wrote and illustrated “Corvette From the Inside” and he’s a frequent and revered guest of honor at all of the top Corvette events. In 1999 McLellan was inducted into the National Corvette Museum’s Hall of Fame. McLellan goes down in the Corvette history books as the second of the five great Corvette chief engineers. – Scott

Corvette Chiefs, Pt. 1 of 5 – Zora Arkus-Duntov, Corvette’s Nostradamus

Duntov carried the heart and soul of the Corvette into racing and created an American legend.

(Dateline: 7-3-20 – This story was originally published in the now-defunct Vette magazine, June 2019 issue) Arguably, there had never been a chief engineer of an American car the likes of Zora Arkus-Duntov. When Duntov was hired to work at Chevrolet on May 1, 1953, the 43-year old European-trained engineer brought a background that made him uniquely qualified to become Corvette’s first chief engineer.

As a young man, Duntov was into boxing, motorcycles, fast cars, and pretty girls. After his formal engineering training in Berlin, Germany, Duntov started racing cars and applying his engineering skills to racecar construction. In 1935 Duntov built his first racecar with help from his racing partner Asia Orley; they called the car, “Arkus”. Their goal was to debut the car at the Grand Prix de Picardie in June 1935. But after a series of mishaps, the car caught fire and never raced. From this point forward, all Duntov wanted to do was build racecars.

In the 1930s Auto Union and Mercedes built the best racecars in Europe. Duntov wrote a technical paper about a new racing concept for the German Society of Engineers titled “Analysis of Four-Wheel Drive for Racing Cars”. at the 1937 Automobile Salon in Paris, Duntov met Dr. Ferdinand Porsche, the designer of the Mercedes-Benz SS and SSK racers, and French performance-car builder and designer, Ettore Bugatti. Mercedes-Benz cars were complex engineering marvels, but Duntov appreciated Bugatti’s elegant simplicity, raw speed, and the success of his cars with privateers. “Simplicity and privateers” are two hints of things Duntov would later do with Corvettes.

After marrying Elfi Wolff in 1939, war broke out in Europe, and Duntov and his brother Yura had a brief stint in the French air force. France fell quickly and Duntov and his family made their way to New York. The brothers setup the Ardun Mechanical Corporation and worked through the war years as parts suppliers for the U.S. military. After the war Duntov and Yura turned their attention back to racecars and started producing their Ardun Hemi Head Conversion kits for flathead Fords.

Post-war years were difficult and by the early ‘50s Duntov was looking for an engineering job with a major Detroit car company. His goal was to find a company that would let him build racecars. When Duntov saw the first Corvette at the 1953 Motorama, he immediately pursued GM, specifically to work on the new Corvette. Chevrolet general manager Ed Cole hired Duntov and assigned him to work under GM suspension master, Maurice Olley; the clash was immediate. Olley was reserved and a numbers-cruncher; Duntov was outgoing and designed by intuition. Six weeks after being hired, Duntov requested time-off to race a Cadillac-powered Allard JR at The 24 Hours of Le Mans. Olley refused, but Cole got him off the hook to race at Le Mans, but without pay. Duntov was so irritated that he almost didn’t come back from France. After his return, Duntov reassigned and started testing special parts to improve the Corvette’s suspension and general performance.

When the 265 small-block became available in 1955, Duntov took a modified ’54 Corvette with the new engine and some aero mods to the GM Phoenix Arizona test track where he was clocked at 162-mph. The mule Corvette was later rebodied as a ’56 Corvette and was part of a team of three Corvettes that were taken to the 1956 Speed Weeks event at Daytona Beach where Corvettes set speed records. Then in March at the 1956 12 Hours of Sebring race, Corvette scored its first major class win. Duntov and three-time Indy 500 winner and engineer Mauri Rose were then tasked by Ed Cole to design, develop, and make available, special Chevrolet-engineered racing parts. When the Rochester Fuel Injection option was released in 1957, RPO 684 Heavy-Duty Racing Suspension was there for privateers that wanted to race their Corvette.

The Bugatti pattern was laid down; make simple, fast cars, and let the privateers do the racing. Duntov also built a few purpose-built Corvette racecars. The 1957 Corvette SS was a good first step but the timing was bad because of the 1957 AMA Racing Ban. The Grand Sport was similar to the RPO Racer Kit program, only a complete, basic racing Corvette was to be sold to privateers. Again, the AMA Racing Ban killed the project. If Duntov hadn’t pushed racing, the Corvette would have morphed into a Thunderbird-like four-seater and been killed by the early ‘60s.

Duntov laid out three design concepts that took decades to implement. The first was his proposal for the 1957 Q-Corvette. This design called for the following: an all-aluminum, fuel-injected small-block engine, four-wheel independent suspension, four-wheel disc brakes, and a transaxle. This design concept arrived in 1997 as the C5.

The second design concept was the mid-engine layout. Duntov’s first mid-engine concept was the 1960 CERV-I. The design parameters were those of an Indy 500 racecar, but with a larger engine. Duntov’s second mid-engine car was the 1964 CERV-II. The third concept in the CERV-II was its unique four-wheel-drive system. Using transaxle parts from the Pontiac Tempest, the system “worked” but would not have lasted as a racecar.

Through the ‘60s several other mid-engine “Corvette” cars were built, but not by Duntov. Engineer Frank Winchell’s 1968 Astro-II Corvette was a beautiful attempt, but like all mid-engine Corvette proposals, it went nowhere. In 1970 Duntov showed his XP-882 with a transverse-mounted 454 engine. After the car was shown at the 1970 New York Auto Show, it went into hiding for some reason. Later, the chassis was used to build the Four-Rotor mid-engine Corvette that was later retrofitted with a small-block engine and rebranded “Astrovette” in 1976, after Duntov retired.

Just after the debut of the C7, the Corvette community started buzzing about the mid-engine C8. For a time the C8 was an unconfirmed rumor until Chevrolet announced that, yes, a mid-engine Corvette was in the works. In 2018 camouflaged mule cars started being seen on public roads. In July 2018 a camouflaged C8.R was seen being tested. Towards the end of 2018 speculation was that the C8 would debut at the 2019 Detroit Auto Show. Then in December 2018, Chevrolet announced that the C8 would be delayed “at least six months” due to “serious electrical problems.”

An insider friend has been telling me for over a year that they were having serious problems getting the car right, but he wasn’t specific. Then another hint was dropped; the problem is with the car’s 48-volt electrical system. Why would the C8 have a 48-volt system? Answer; because it will have auxiliary electrical front-wheel drive. Suspension and traction is everything, so AWD is inevitable.

While Duntov didn’t “predict” the Corvette’s future, he certainly set the course. His insistence that Corvette be tied to racing, kept the car from becoming Chevy’s Thunderbird. The features of the 1957 Q-Corvette are the very design foundation of the C5, C6, and C7 Corvette. The CERV I, CERV II, and the XP-882 (minus the transverse engine) will live in the mid-engine C8. And it is likely that the CERV II’s all-wheel-drive concept will live in the C8, only as an electrical, and not a mechanical system. Without one man’s obsession with building racecars, there’d be no Corvette legend. – Scott

Jim Perkins Tribute: R.I.P. Corvette Corporate Angel

Jim Perkins: The Man That Saved the Modern Corvette

(Note: this story was originally published in the March 2019 issue of Vette Vues Magazine) – The Corvette is the most unlikely of all cars for a company such as General Motors to produce. GM is all about producing huge volumes of cars and trucks. When the Corvette came out as a late offering in June 1953, only 300 cars were hand-assembled. Engineers and builders were literally designing as they were building the cars. Sales jumped to 3,640 for 1954 and tanked to just 700 in 1955. Harley Earl restyled the Corvette for 1956 and sales went up to 3,467 units and then 6,339 for 1957. Meanwhile Ford sold 16,155 T-Birds in 1955, 15,631 in 1956, and 21,380 in 1957! They were killing the Corvette then went to a four-seater configuration, leaving Chevrolet the two-seater sports car market all to themselves. Corvette sales didn’t hit 10,000 units until 1960; not much in the big picture of GM!

The long knives were out for the Corvette inside GM. There were many that didn’t understand the Corvette, didn’t like it, and wanted it dead! What saved the Corvette were its corporate angels; Art and Color Section VP, Harley Earl; Chevrolet general manager, Ed Cole; Senior VP of Design, Bill Mitchell; Zora Arkus-Duntov; and Mauri Rose. The common denominator with all of these men is that they are “car guys”. Bill Mitchell was famous for boasting, “I’ve got gasoline in my veins!” Aside from Duntov and Rose, these men had corporate clout; they could lean on and make things happen.

While general manager of Chevrolet, Jim Perkins was famous for handing out pins with the Chevy bow-tie and the work “Pride” beneath it.

In 1960, after some college attendance at Baylor University and three years in the Navy, Jim Perkins took a job at a Chevrolet warehouse, sorting parts while he finished his degree. Little did Perkins know that thirty years later, he too would become a corporate angel for the Corvette.

Perkins was a Depression Era kid from Waco, Texas. When World War II broke out Perkins’ dad tried to enlist in the military but was told he was “too old”. This was a time when men did whatever they had to do to put food on the table. Being mechanically inclined, Perkins’ dad started fixing cars, then buying, and selling cars. Perkins spent a lot of time with his dad and at the age of 14, he got an after school job at a local Texaco service station. Perkins quickly developed a reputation as a very good Chevy mechanic. Perkins fixed and sold a series of cars and finally got a hot ’52 Oldsmobile. But when the ’55 Chevy came out, he sold his Olds and made enough for a new Chevy. From here forward, Perkins was a Chevy car guy!

After graduating from high school, Perkins took courses at Baylor then served three years in the Navy. After his discharge from the Navy, he took a low-level job, sorting parts at a Chevrolet warehouse, while completing his college courses. With his Navy experience and eventual degree, Perkins quickly rose through the ranks at Chevrolet in Sales & Service. In the mid-‘70s, he landed a peach-of-a-job working for then GM president, Pete Estes. That’s where Perkins learned the ropes of GM corporate life.

After a few years working for Estes, Perkins was transferred to Buick. Detroit was struggling to come out of the 1970s recession and how to deal with the success of Japanese cars. Perkins was working under Lloyd Reuss and it was a good relationship. “Just In Time” production was a new concept and Perkins was doing many of the management tasks that Lloyd normally would have done, and he loved it! The first two years they set records; then management changed.

The new top guy at Buick was Don Hackworth and it wasn’t a good mix for Perkins. The two men almost immediately started butting heads. On a plane coming back from a business meeting, Perkins asked Hackworth what they could do to have a better working relationship. Hackworth suggested a “foreign assignment” for Perkins. That was IT for Perkins. What Hackworth didn’t know was that Toyota was wooing Perkins for an executive position. The timing was perfect

When Perkins came into Toyota with his “GM top-down” management style, he was nearly stopped in his tracks. The Japanese car companies were all using the “Consensus Process”; which starts from the bottom (assembly workers) and goes up from there. Perkins quickly learned that while the process takes longer, the execution is like a rocket ship; everyone is onboard and you get better solutions.

A year later, Toyota made Perkins Group V.P. for Sales, Marketing, Distribution, Product Planning, and New Ventures. Around this time Japanese car companies announced that they were taking on the luxury car segment of Mercedes and BMW. Mr. Toyoda wanted to prove to the world that they could build world-class luxury automobiles. Toyota formed Lexus and Perkins was a key player.

Then, an extraordinary thing happened; GM wanted Perkins back! Typically at GM, once you leave, that’s it. Perkins learned from his former boss, Lloyd Reuss, that then-GM president Bob Stemple (another car guy!) wanted to talk to Perkins about coming back. When the two men talked, Perkins told Stemple, “There are two jobs I would come back for; president of GM, or general manager of Chevrolet.” Stemple’s reply was, “Well, that’s a little lofty.” Stemple and Perkins continued their conversation for a time before Stemple called Perkins. “OK, big boy, it’s time to put up of shut up. We’ll make you general manager of Chevrolet.”

It had been twenty-nine years since car guy mechanic Jim Perkins started sorting parts in a Chevrolet warehouse. In May 1989 Perkins was made general manager of Chevrolet. He’s always been a Chevy-guy, and now he was running the division. But when Perkins got back, he was in for a shock. Perkins said in a 2014 interview with Motor Trend, “I didn’t recognize Chevrolet when I got back. It had lost its pride. There was so much infighting among sales, marketing, product planning, distribution, you name it. Everywhere you looked was a silo with its own management, and that’s the kiss of death.”

The CERV IV was really a C5 in drag. Under the stretched body was a full C5 frame and suspension. This is the car that convinced GM management to go ahead with the C5.

TCE” Total Customer Enthusiasm had to start at the top, meaning that managers with bad attitudes had to go. Using Toyota’s “Consensus Process” concept, Perkins invited his people to write to him about the problems they faced and possible solutions. Perkins got 1900 letters, read them all, distilled them into to-do lists, and formed employee councils to come up with working plans. A lot got fixed, workers felt their experience mattered and the organization was much happier. The same concept was also applied to the dealer networks.

By 1990 the nation’s economy was moving into another recession and things were not good inside GM. All car lines were being closely reviewed and Corvette sales were in a downward direction. Once again, the car was on the chopping block. According to Corvette designer, John Cafaro, by 1992 the Corvette almost died. People in the company didn’t understand the car and no one wanted to champion the car. Former GM executive Ralph Kramer said, “Many GM insiders considered the Corvette to be a non-essential product in the GM/Chevrolet stable. The thought that the Corvette would NOT just be in the Chevy stable of cars, but instead the main character; the stud-horse; the Secretariat; was totally remote to the Corvette-haters; but how could it not be otherwise?” (Today, the Corvette is THE flagship of GM)

GM’s Mid-size Car Division managed Joe Spielman (also a car guy and Corvette fan) created a task group called, “The Decision Makers”. The group consisted of himself, Carlisle Davis, John Cafaro, and Dave McLellan. The team’s objective was to create a path for the future of the Corvette. They came up with three directions; First: A production version of the 1990 mid-engine CERV-III; Second: The Momentum Architecture, featuring an evolutionary body style, a stiff backbone-type chassis, and a transaxle; and Third: the “Stiffer and Lighter” design which was a lighter and improved C4. The team chose the “Momentum Architecture”. The problem was funding.

In November 1992 Dave Hill took over as Corvette’s chief engineer and had a big problem on his hands; how to prove the concept of the Momentum Architecture when he had no budget. Corvette manager Russ McLean went the Perkins and explained that the Corvette team needed funding for another CERV Corvette (Corporate Engineering Research Vehicle) to prove the viability of the Momentum Architecture concept. Perkins managed to pull $1.2 Million from another budget to allow Hill’s team to build what is arguably the stealthiest R&D Corvette ever, the CERV IV.

This is the 1995 Indy 500 Corvette Pace Car that Jim Perkins drove to start the 1995 Indy 500.

The CERV IV was essentially a C5 structure wearing a C4 body. A keen eye would have noticed that it looked like a “l-o-n-g” C4 Corvette, but when the car was on public roads, no one noticed. When Hill took executives for a ride, they all said, “This is like no Corvette we ever felt!” Hill proved to GM’s president, Jack Smith, that his team could reinvent the Corvette, as well as the building process. The $1.2 Million that corporate angel Perkins was able to secure for the CERV IV saved the Corvette! It was something that ONLY Jim Perkins could have done.

In 1996, at age 61, Perkins retired from Chevrolet. In his seven years as Chevrolet’s general manager he rekindled Chevy’s 1960’s-style pride; improved Chevy’s truck production; strengthened Chevy’s role in product development and design; helped his people come to grips with downsizing and reorganization, supervised the Chevrolet Racing Team that won five NASCAR Championships and had six Indy Car victories; and got to drive the pace car at the Indy 500 three times in 1990, 1993, and 1995 (in a Corvette).

While it doesn’t look like it, the C5 is the most radical new production Corvette ever offered, thanks to its new hydro-formed perimeter frame, center spine structure, all-aluminum LS1 engine, and transaxle.

In the 2014 Motor Trend interview, Perkins said this about driving the Indy pace car, “You come out of turn four when you’re going to turn them loose, you know you have to make the left turn into the pits, you look down the track, and it looks like everything is closing in on you with all the people and color and movement. You swear you’re going through the eye of a needle. My God, it is such a tremendous, tremendous experience.”

Retirement from Chevrolet only lasted three months when Perkins accepted an offer from Rick Hendricks to take over his company after he came down with leukemia. Perkins stayed on as the CEO and later COO. Perkins said of his time at Hendricks Motorsports, “If ever anything has been rewarding, it has been seeing this company do what it has done. I have no regrets. It’s been a blast, a great, great, great ride.” In 1999 Jim Perkins was inducted into the National Corvette Museum’s Hall of Fame in the GM-Chevrolet Category.

Jim Perkins was a poor kid from depression-era Waco, Texas that liked to work on Chevys. He was described as a “wily, free-speaking, cowboy boot-wearing Texan.” Perkins died on December 28, 2019 in Charlotte, North Carolina. Jim Perkins was 83 years-of-age. Perkins had an exemplary career and most importantly to the Corvette community, saved the Corvette. – Scott


 

The Duntov Files, Pt. 1 E-Book: Zora’s 1969 427 ZL1 Racer

New series of FREE Corvette E-Books from K. Scott Teeters’ collection of Corvette Reference Material

Dateline: 10.19.19 – To download this free E-Book, CLICK HERE –  I have a very large collection of Corvette magazines and magazine clippings that date back to the late 1950s. Recently I was talking to a Corvette restoration expert about a project that he wants to take on. George is considering building a replica of Zora Arkus-Duntov’s 1969 427 ZL1 development mule.

Image: SuperChevy.com

This car got a good amount of ink back in 1969 and I have clippings of most of the published stories. So I scanned the pages and sent them to George for his reference. Then it occurred to me that to preserve this material, I should make themed PDF versions of my collection and put them out there to the Corvette community.

I’m calling the first wave of PDFs “The Duntov Files”. Corvette has always been a large group effort, but every successful enterprise has to have an enthusiastic figurehead. The Corvette is what it is today because of Duntov’s single-minded focus on Corvette racing. Were it not for racing, the Corvette wouldn’t have made it out of the 1950s.

This was one of Duntov’s many mule (toy) Corvettes.

Duntov’s built his 427 ZL1 development Corvette as if he was building an A/Production race car. Anything that wouldn’t be on a Corvette race car was removed. The car was outfitted with L88 fender flares to cover the wide American racing mag wheels shod with racing tires. The all-aluminum 427 ZL1 was opened up with racing headers and side exhaust. All Zora needed was numbers on the car and some sponsor decals. This was one cool toy!

Enjoy and feel free to share with your Corvette friends. – Scott

Corvette’s Founding Fathers, Pt 1 of 6 – Designer Extraordinaire, Harley J. Earl

The Roman philosopher Seneca is credited for saying, “Luck is what happens when preparation meets opportunity.” When Harley Earl attended his first organized road race at Watkins Glen in September 1951, (the very first Watkins Glen Sports Car Grand Prix was in 1948) two things were glaringly obvious to him; First; “sports cars” were not a fad, there was real passion for the unique European cars he saw racing through the streets of Watkins Glen. And second: General Motors needed to build an American sports car – right away!

By 1951 Harley Earl was entering the twilight years of his long career in design and innovation. He was a true living legend. Earl knew everyone who was anyone in the automotive world and then some. He wielded so much power inside General Motors that he had a button on his desk to get a direct call to GM’s president Alfred P. Sloan. Earl was a personal friend of United States Air Force General Curtis LeMay and one day in the early 1950s the general said to him, “Why don’t you make an American sports car?”

The Strategic Air Command general loved sports cars and owned an Allard J2. GM even built LeMay a special Cadillac-powered Willys Jeep. LeMay was also instrumental in helping start the Sports Car Club of America and in 1954 was the recipient of the Woolf Barnato Award, the SCCA’s highest award for club contributors. Barnato won the 24 Hours of Le Mans in 1928, 1929, and 1930 and he was the only driver to ever win the Le Mans race every time he entered!

Inside Bill Mitchell’s Secret Garage – 2 VIDEOS

A walk on “hallowed ground” of Corvette design.

Dateline: 11.18.17 – My monthly column in VETTE Magazine, “The Illustrated Corvette Series” is now in its 21st year. I’m in the middle of a series I’m calling, “The Corvette’s Founding Fathers” that covers the careers of Harley Earl, Ed Cole, Bill Mitchell, Zora Arkus Duntov, Larry Shinoda, and Peter Brock. Each of these men played a foundational roll in setting the pattern and personality of the Corvette. Without them, the Corvette might not have survived the 1950s.

I’m now working on installment number three, covering Bill Mitchell that will appear in the May 2018 issue of VETTE Magazine and will be out in March 2018. While researching Mitchell Continue reading

The Motion Performance Experience – Part II

An Intimate Conversation With Martyn “Marty” L. Schorr and Joel “Mr. Motion” Rosen – Co-Founders of the Baldwin-Motion Supercars
Dateline: 8.10.17 / Photos:  Martyn L. Schorr & K. Scott Teeters’ Baldwin Motion Magazine Archives, Mecum Auctions, Dan McMichaels, & Google Maps Part one of my 2013 Far Out Radio conversation with Marty Schorr and Joel Rosen is in the July 2017 issue of Vette Vues can be enjoyed HERE. The year 2017 marks the 50th Anniversary of the Baldwin Motion Experience. Before we get into the rest of my 2013 conversation with Marty and Joel I’d like to share an anecdotal story about setting up the interview.

I have known Marty Schorr since 1976, just after he started “VETTE Quarterly”, the first Corvette-only, newsstand publication. I’ve had numerous conversations with Joel since around 2000 and always found him to be polite, but very reserved. When I asked Marty if he’s like to me on my radio program he said, “Sure, I’d be happy to.” When I asked Joel, he said, “Well, okay, but I don’t really have that much to say. How long is the interview?” I told him I did a one-hour show and without the commercials and bumper music, we have around 45 minutes to talk. He said, “Oh… I really don’t have that much to say, Scott. Really.” So, I assured him that if he ran out of things to say, Marty would fill in the rest. When the show started, Joel was reserved, as usual, but quickly loosen up. Before I knew it, he was seriously bench racing! As the host of the show I carefully watch the clock. When I said, “Well guys, we’re just about out of time, Joel said, “What! We just got started!” That’s just what happens when car guys get to bench racing.
