Just a few weeks after pictures of the Blue Devil/SS/Sting Ray were first taken, another test mule was spied just outside of Ann Arbor heading for EPA testing.

The monster hood scoop most likely contains the supercharged 6.2 liter V8, with horsepower output expected in the 650 range. The engine will be hand assembled side by side with the 7.0 liter LS7 Z06 engine at the GM Performance Center with production expected in the 1500-2000 range.
