[SVT ZX3]

CTS-V is pimp for sure, but I'm pretty shocked it'll take down an SRT-8. Must be a serious weight difference. Too bad it costs an extra $20k MSRP over teh Chrysler.Either way the CTS-V does use the same engine (designated LS6) from the last generation (C5) Corvette Z06. Breaks down like this....

(C5) 04 Corvette base model 350hp (5.7L)
(C5) 04 Corvette Z06 model 405hp (5.7L) ----> CTS-V engine, but looses 5 hp
(C6) 05 Corvette base model 400hp (6.0L)
(C6) 05 Corvette Z06 model 505hp (7.0L)

Quote:When the CTS first hit the showrooms, it was only available with a rather anemic V6 - Cadillac stressed that its design was too compact to slip the Northstar V8 engine under the hood. However, the CTS engineering team looked to Chevrolet's Corvette line where they determined that with a few minor modifications the potent LS-6 V8 would fill the engine bay. Generating 400-horsepower and a tire shredding 395-lb.-ft. of torque this new 5.7-litre aluminum-block heart gives the CTS-V driver an adrenaline rush like few other street sedans.
