Video: Corvette ZR1 top speed run

An engine eagerly speculated to feature in the HSV line-up sometime in the not too distant future, the LS9 powerplant is a 6.2L supercharged V8 producing 476kW and 819Nm.

This makes it GM's most powerful engine - ever, and is hand built by specially trained technicians at GM’s Performance Build Center in Wixom, Michigan alongside HSV's LS7 engine for the W427.
