Chevrolet has been spotted testing a few prototype versions of the 2018 Corvette ZR1 out on the streets in the US, sporting a few different albeit all racy rear wing setups.
The prototypes were spotted in Michigan by an IndianAutosBlog reader, giving us all our first look at the new model in video footage.
There have been a lot of rumours spreading in regards to the new ZR1, with speculations suggesting a mid-engine layout, and others tipping a 700hp (522kW) power output.
All of this isn’t helped by the fact GM seems to be testing various prototypes with slightly different highlights. In the video below, for example, there are three different versions including a convertible. And all three use a different rear wing.
One of them appears to feature composite body panels with a red roof and side mirrors. The two travelling behind are the most heavily-clad, wrapped in black covering to conceal the design of the front end.
According to reports the 2018 Corvette ZR1 will be powered by an iteration of Chevrolet’s new LT4 engine. It’s a 6.2-litre supercharged V8, as seen in the current Z06 where it produces 485kW and 881Nm.
For the ZR1, power is expected to be pushed up to around 700hp, or 522kW. This would make it the most powerful Corvette ever, however, it would fall just short of Chrysler’s 527kW Hellcat V8 in terms of being the muscle champion.
Behind the engine is set to be a six- or seven-speed manual and the option of a new 10-speed automatic, with rear-wheel drive. More details are likely to trickle out over the coming months. We’ll be sure to keep you updated.
