Chevrolet Corvette ZR1


Chevrolet Corvette ZR1

Easily the most technologically advanced engine ever put in a Corvette, the LT5 was only part of the ZR1 package. The car entered production in 1990 after much hype, and immediately looked different, thanks to the wide rear bodywork, to allow fitting of 11x17-inch (276x432mm) alloys with 315/35 tyres. Lotus designed the engine and based it on Chevy's small-block V8, but started with an aluminium-alloy block. Completely new heads used two-cams-per-bank operating four valves per cylinder. The induction used two ports and injectors per cylinder and only one of each operated below 3,500rpm. Above this with the throttle floored the other port and injector would open up and allow the full 405bhp (302kW) on later models to be unleashed. Other high-tech gadgetry included the suspension on which the driver could select a setting: Touring, Sport or Performance.
