- This rare C4 ZR1 prototype is set to hit the Mecum auction in January.
- The iconic blue Corvette was left behind in the UK during LT5 testing by Lotus.
- Rescue efforts by Mike Yager in the 1990s led to its restoration in the United States.
The latest ZR1 and ZRX models have firmly established the Corvette in supercar territory. Yet, this is not the first time General Motors has ventured into this arena, challenging heavyweight rivals like Ferrari and Lamborghini.
Decades ago, the C4 ZR1 fulfilled a similar role, and one of its rare surviving prototypes is on its way to auction.
This metallic blue 1989 Corvette nearly met an untimely end. Unlike other prototypes that were preserved, this vehicle was abandoned, left in a field in England, forgotten until a restoration effort resurrected it after eight long years.
The GM Connection
What led to a rare Corvette prototype being left in a remote UK location? Thanks to Lotus Engineering, which created the ZR1’s DOHC LT5 V8 and ensured the suspension could handle its immense power.
At that time, General Motors owned Lotus, and throughout the late 1980s, numerous test cars were circulating. Once the project concluded, the intention was to crush these vehicles, but a few surprisingly survived in dire condition. A look at the images from this car’s discovery in the mid-1990s tells the story.
When Mike Yager, a Corvette specialist, found this C4, he returned it to the U.S. and undertook the extensive restoration to bring it back to like-new condition. Out of the 84 ZR1 Corvettes made in 1989 for engineering evaluation, incomplete testing, and press previews, this is reportedly the only one that emerged with this stylish blue-on-blue design.
A Beast For Its Time
Powered by the 375 hp (380 PS) LT5, the ZR1 experienced a significant performance leap over the standard 240 hp (243 PS) L98 pushrod V8 C4s, allowing it to achieve a top speed of 180 mph (290 km/h).
Visually, while both models appear similar, the ZR1 features a stretched rear body design by three inches (75 mm) to accommodate wide 11.5-inch wheels, and a modified rear panel transitioning from concave to convex.
C4 ZR1s remain remarkably undervalued in today’s market. Enthusiasts can find low-mileage examples for as little as $25,000, with pristine models fetching under $70,000. However, given this particular car’s unique history, it’s expected to attract bids around $250,000 at Mecum’s Kissimmee sale in January.
That kind of investment could also secure you a 2026 ZR1. Which would you choose to spend your hard-earned cash on?
