A little bit of snow? That's nothing.
The C7 Corvette ZR1 is coming soon, and Chevrolet is currently doing some final performance testing at the famed Nurburgring, as this recent spy video clearly shows. And yes, this advanced prototype is testing in wet and snowy conditions, which is definitely not ideal at a place like the Ring. Based on previous spy shots, it's 100 percent clear this is the ZR1, due to the large rear wing and other added aero upgrades. Strangely, however, we can't seem to hear the sound of forced induction in this particular video. Maybe it's just the audio. Who knows?
We previously predicted that an upgraded version of the Z06's LT4 supercharged V8 would power this ultimate (and likely final) front-engined 'Vette. There's also an older rumor claiming that Chevrolet is resurrecting a DOHC V8, specifically the so-called LT5 V8. It's possible this latter option could be resting under the ZR1's hood.
But for right now we just don't know. As to when the ZR1 will have its official debut, some have suggested it'll happen later this summer, perhaps at the Woodward Dream Cruise. The 2018 Detroit Auto Show is another possibility, but GM could be saving that for the C8's debut. Nevertheless, if this engine is an upgraded LT4, expect output to be around 750 hp, up from the Z06's 650 ponies.
