GM started the project and built two dozen Corvette ZR1 Active Suspension prototypes.

The automobile industry is based on a wide range of technology. 

But occasionally, a technology that a vehicle manufacturer wished to use was found to be too cutting-edge for the period. 

Earlier, General Motors desired to equip the 1990 Chevrolet Corvette ZR1 with active suspension technology. 

Therefore, GM launched a project and produced 20 Corvette ZR1 Active Suspension prototypes. 

Even though these prototypes were ultimately scrapped, one of them is still available at Hemmings.

ZR1 Package Not Enough For 1990 Corvette

A model's attraction diminishes with age. Car manufacturers usually provide souped-up versions of their older (of the same generation) vehicles to make them more marketable. 

In 1983, Chevrolet unveiled the Corvette's fourth generation (C4). The Corvette C4 was a seven-year-old vehicle by 1990. 

Chevrolet debuted the ZR1 for the model year, which featured a Lotus-tuned 5.7-liter V8 with a maximum output of 375 horsepower and a maximum torque of 370 lb-ft.

The Corvette C4 ZR1 boasts more horsepower than a conventional Vette, a wider rear track, bigger tyres, 

and the FX3/Z51 performance suspension, which includes adjustable dampers, sport-tuned springs, and a thicker rear anti-roll bar.
