General Motors is on the verge of releasing another great sports car – after the Camaro ZL1 we’re now eagerly awaiting the apparition of the current generation Corvette ZR1.

Fortunately, the wait is going to be eased by this latest spy video depicting the prototypes being fine-tuned by Chevy engineers on the Mazda Raceway Laguna Seca. The clip is also a great chance to hear for the first time the roaring sound of the mighty V8, which sounds exactly how it should on a hardcore version of the already great sports car. The video is also showing that Chevrolet is actually developing wo wings for the ZR1. One of them is a bonkers large, fixed unit that seems to have the same height as the roof – while the smaller example is equally aggressive but not that huge. The simultaneous development is a hint towards a possible ZR1 optional, high-downforce body kit for better track performance.

According to previously leaked internal documents, under the hood lies a new engine – with internal name of LT5 – an aluminum 6.2-liter unit with variable valve timing, and dual-overhead cam layout instead of the usual ‘Vette powerplant’s pushrods. According to media reports, this powerplant might deliver more than 650 horsepower (485 kilowatts), which is the power developed by the current Z06, which uses the supercharged 6.2-liter V8 with LT4 designation.
