It has recently released a video showing it isn't kidding and has proved that its ZR1 can indeed do more than the claimed figure. With a supercharged 6.2-litre V8 cranking out 755bhp, the front-engined sports car achieved an average of 212mph (341km/h) at the Papenberg test track in Germany.
Without the ZTK Performance Package that includes the large carbon fibre rear wing, the car did two runs which saw a highest recorded speed of 345.5km/h in seventh gear.
Interestingly, the American coupe might still have more go. According to its Chief Engineer, Tadge Juechter, the team didn't expect the car to hit its 215mph (345km/h) limiter and were surprised when it did.
“We talked about raising it [the limiter], but the tires were validated to 215mph.”
