The Corvette’s C4 model years 1984 through 1996 established a loyal following as one of the world’s most desirable sports cars. The convertible was back, and with higher performing engines exemplified by the 375 hp (280 kW) LT5 found in the ZR-1, enthusiasts could not get enough of the heavy brute force, dizzying speed and superior race-car handling. Known for its evolved, sleek and modern look, the C4 is one of the most powerful versions of the Corvette ever sold in America.

This ‘wild beast’ was built with one clear purpose – speed – in March 1990, the ZR-1 set a new record for the highest 24 hour-5,000 mile land-speed by going over 175 mph (282 km/h). The Corvette/Lotus collaboration resulted in what GM dubbed the LT5, an all-aluminium-block V-8 with the same displacement, 5.7 litres or 350 cu. in., and the same bore centres (4.4 in.) as the normal Corvette's L98 pushrod engine. Lotus also designed a unique air management system for the engine to provide a wider power band by shutting off 8 of the 16 intake runners and fuel injectors when the engine was at part-throttle, while still giving the ZR-1 375 hp (280 kW) when at wide open throttle.

In addition to the engine, Lotus helped GM design the ZR-1’s upgraded braking and steering systems, ensuring the vehicle was more than just a modern day muscle car with a big engine and no real capacity on the track. The infamous “King of the Hill” was distinguishable from other Corvette coupes by its wider tail section, 11" wide rear wheels and its new convex rear fascia with four square shaped taillights and a CHMSL (centre high mounted stop lamp) attached to the top of the hatch glass instead of between the taillights.

Mercury Marine of Stillwater, Oklahoma, were contracted to assemble the ZR-1 engines, and a range of other upgrades were offered including better brakes and retuned adjustable active ride control modes. In 1991, the ZR-1 and base model received updates to body work, interior, and wheels. The rear convex fascia that set the 1990 ZR-1 apart from the base model found its way to all models, making the high-priced ZR-1 even less distinguishable on the road.

This right hand drive (RHD) vehicle was imported into Australia in 1995 being converted to RHD and complied by Corvette Clinic Victoria the same year. This ZR1 is painted bright red, matching targa roof with black upholstery. Fitted with a 5.7 litre 375 hp all alloy 4 cam, 32 valve engine and 6 speed ZF manual transmission.

The car has been actively exhibited at Corvette club events in NSW and QLD including the National Corvette Restorers Society (NCRS). Amongst its awards, it received a Top Flight Award at the ‘Corvettes in Heaven’ NCRS meet on April 3rd,4th,5th 2007 judged by Murray Forman.
