Up for auction is this 1990 Chevrolet C4 Corvette ZR-1 finished in Charcoal Metallic over a gray leather interior. The ZR-1 was introduced in 1990 as the most powerful and high-performance Corvette yet, equipped with an all-aluminum 5.7L V8 LT5 engine developed in collaboration with Lotus. This ZR-1 is said to be one of only 41 examples appointed with gray leather and Charcoal Metallic paint, a color offered exclusively in the 1990 model year. It was acquired from its original owner out of Michigan earlier in 2021 and had reportedly been kept in climate-controlled storage since new. Now showing just over 2k miles on the odometer, this 1990 Corvette ZR-1 is being offered for auction out of Pennsylvania accompanied by its original window sticker and complete ZR-1 “Pizza Box”, a serialized leather pouch containing the original gold ZR-1 keychain, owner’s books, and a VHS tape.
This ZR-1 is finished in Charcoal Metallic (U96), a highly desirable color offered for the 1990 model year only. The C4 ZR-1 featured model-specific bodywork including widened rear quarter panels and a convex rear fascia with squared-off taillights. Exterior details include a bronze-tinted removable glass roof panel, painted mirror caps, pop-up headlights, integrated front fog lights, fender vents, quad exhaust outlets, and a ZR-1 badge on the tail panel. This Corvette rides on staggered-width 17” machined “Sawblade” wheels, which remain dressed in original Goodyear Eagle Gatorback tires specially designed for the ZR-1. The seller recommends mounting new tires for road use and describes the finish to be preserved in excellent condition overall, a clean CARFAX report is provided in the gallery.
The interior of this ZR-1 features deeply bolstered six-way power-adjustable sport seats trimmed in light gray leather, with matching carpeting and door panels. Amenities include automatic climate control, a trip computer, power windows and locks, cruise control, a low-pressure tire warning system, and a Delco-Bose Gold Series stereo with a cassette and CD player. All features and accessories are said to remain fully functional.
The C4 ZR-1 is powered by an all-aluminum 32-valve quad-camshaft LT5 V8, developed jointly by Chevrolet and Lotus, and manufactured by Mercury Marine of Stillwater, Oklahoma. The LT5 was factory rated at 375 HP and 370 lb.-ft of torque when new and drives the rear wheels through a ZF 6-speed manual transmission and mechanical limited-slip differential. The ZR-1 can reach 60 MPH from a standstill in less than 5 seconds on to a claimed top speed of 180 MPH. Lotus was also involved in the design of the braking, steering, and suspension systems. The Bilstein FX3 adaptive suspension uses a gas-over-oil shock absorber that allowed the driver to electronically control 6 different damping settings in each of the three driving modes, Touring, Sport, and Performance. Stopping power comes from four-wheel disc brakes with Bosch ABS. Standard routine maintenance has been observed throughout the years and the car has been periodically driven in good weather for mechanical exercise.
This sale will include a set of keys and the complete matching-numbers ZR-1 “Pizza Box”, containing the original window sticker, owner’s manuals, a gold ZR-1 keychain, and an owner’s VHS tape. Beautifully preserved under the care of its original owner, this rare 1990 ZR-1 makes an excellent investment for any collector, do not miss out.
