2018 Chevrolet Corvette ZR1 Coupe and Convertible Spied Testing against Hellcat

Both the 2018 Corvette ZR1 Coupe and Convertible have been spied in Marrietta, Ohio, with photographer David Wesel catching the supercars on camera and sharing his work with us via the 'Vette-loving community over at CorvetteBlogger.

As for the full testing line-up we mentioned in the intro, this also includes the GM supercar's (more or less direct) competition, as the six Corvette prototypes were spotted playing with a Dodge Challenger Hellcat, as well as a Jaguar F-Type.

According to the photog, one of the Chevys in the group was a Grand Sport driven by Corvette product manager Harlan Charles.

Compared to the fixed-roof prototype spied on the previous occasion, the Convertible we have here comes with a smaller rear wing. However, the prototypes remain heavily covered, whether we're talking about the all-clad front apron or the psychedelic wrap on the rear end.

Speaking of the 2018 Corvette ZR1's front section, don't expect the LT5 V8 that GM is currently developing to show up on the supercar, as this should debut on the future C8 Corvette.

Instead, the ZR1 will probably be motivated by an even beefier version of the C7 Z06's LT4. And with the blown 6.2-liter V8 already delivering 650 ponies, we're expecting one spicy recipe.

The C6-gen ZR1, which showed up as a 2009 model year vehicle, was better on the straights than it was through the twists. Well, the new ZR1 will be a complete super-fast beast, so expect extreme cornering abilities.

As we've mentioned in the past, the 2018 ZR1 might just be a swansong for the front-engined Corvette, as the C8 generation of the machine will switch to a mid-engined configuration - here's a set of spyshots for all you non-believers out there.
