LSA
The supercharged 6.2L LSA is similar to the LS9 and debuted in the 2009 CTS-V. The LSA has been SAE certified at 556 bhp (415 kW) at 6100 rpm and 551 lb·ft (747 N·m) at 3800 rpm. GM labels it "the most powerful ever offered in Cadillac’s nearly 106-year history". The LSA features a smaller 1.9L capacity supercharger rather than the 2.3 L variant of the LS9. Other differences include a slightly lower 9.0:1 compression ratio, single unit heat exchanger and cast pistons.
A 580 bhp (430 kW) and 556 lb·ft (754 N·m) version of the LSA engine is used in the 2012 Camaro ZL1. On 15 May 2013, Holden Special Vehicles announced that this version of the LSA engine will also be used in the GEN-F GTS.
