A Salute to Chevy’s “King of the Hill” the ZR-1 and ZR1

(Check out the BIG versions of the ZR1 Tribute print on the right, at the bottom of this post.)

When the ZR-1 Corvette first arrived in 1970 almost the only people that noticed were the Corvette racers and a few magazine gearheads. That’s because RPO ZR1 was the latest of Zora Arkus-Duntov’s “racer kits.” The ZR-1 was an LT-1 version of the ‘67-’69 L-88 racer kit package that Duntov deliberately designed to be a “track-only” car. There were no creature comforts – no radio and even no heater. The suspension was completely heavy duty and could jar your molars out on normal streets. Plus, the lack of a proper radiator shroud made driving the car in stop-and-go traffic an engine killer.

Consequently, from ‘70 to ‘72, only 53 official ZR-1 Corvettes were built. After the end of ‘72, the Corvette market began to move away from performance to a boulevard car. It took 18 years for the ZR-1 to surface again, but this time as a world-class Grand Touring road machine. Packed to the gills with creature comforts and powered by the all-aluminum, double-overhead-cam, Lotus-designed, Mercury marine-built LT-5 engine, this was no “off raod use only” machine. When the clamshell hood of the press preview ‘89 ZR-1 was opened, jaws dropped and grizzled automotive journalists gasped at the sight of the LT-5.

The Corvette team was a very different group from the late ‘60s. One thing Dave McLellan and his team were determined to do was make sure their new world-class Vette was NOT launched prematurely. The team intended to release the ZR-1 as an ‘89 Corvette, but smartly chose to postpone production a year to make sure the car was right. The only downside to the entire enterprise was a small matter of the BIG price. At $27,016 on top of the $31,979 base price, this wasn’t just an engine option. No, no. everything from the flywheel back to the tires was bigger, more stout, and heavy duty. And rather than just add flares to the fenders to cover the oversized tires (ala the C3 L-88 fender flares), the entire back end of the car was widened. Unfortunately, the change was only noticeable to those with a keen Corvette eye or if the ZR-1 was next to a regular C4 Corvette. But, we won’t pick, as it was a magnificent car.
