The engines are race-prepped variants of those found in the CTS-V and Escalade. The naturally aspirated units, which are built and maintained by ECR Engines, deliver nearly 600 hp with a redline of 7,600 rpm.
Cadillac states that each engine has experienced nearly 36,000 upshifts and downshifts and 13 hours of wide-open throttle operation, yet hasn’t even undergone a single oil or filter change. Additionally, each engine is repeatedly subjected to forces as high as 3.5 lateral g, 2.0 vertical g, and 3.5 g under hard braking.
Oh. Well, of course.
