Video: Motor Week Tests Two Early 90’s Super ‘Vettes

When GM re-introduced the Chevrolet Corvette ZR1, many younger people were left scratching their heads, wondering where such a funky moniker came from. It came from another, older Corvette, the ZR-1, which debuted in the early 1980’s as the ultimate factory Corvette. Yet from day one, it would have a rival for the crown of King ‘Vette; the Callaway Twin-Turbo Corvettes.

This old, old, old video from Motor Week shows the two early 90’s super Corvettes battling it out on the track. So who did Motor Week crown king?

First some basic stats. Introduced in 1990, the Corvette ZR-1 was fitted with a Lotus-built aluminum-block V8 engine with four-overhead camshafts and 32 valves. The result was a naturally-aspirated engine that made a stunning (for the time) 375 horsepower. Bigger brakes, a racier suspension, and body kit helped round out the package.

Introduced in 1987, the Callaway Corvette came ahead of the ZR-1 and many would argue that it spurred GM on to introduce their own super Corvette. With 390 horsepower and over 560 ft-lbs of torque, as well as a host of suspension and handling mods, the Callaway was nothing to sneeze at either.

In the quarter-mile, the Chevy ZR-1 pulled off a 12.9 at 11 MPH; the Callaway Corvette did it in 12.7 at 114 MPH. Both cars managed to do 0-60 in 4.5 seconds, and they were similarly priced as well. In the end, it comes down to preference… which Corvette supercar would you rather own?
