We thought Bentley's announcement earlier today that it's adding a Speed model to the Continental Flying Spur lineup was exciting news for sedan fans. After all, a 600bhp saloon that can hit 60 mph in 4.5 seconds and reach 200 MPH is pretty exciting, no? Not really when compared to Cadillac's news that the 2009 CTS-V will officially be rated at 556 horsepower, hit 60 mph in 3.5 seconds and run the quarter mile in 12 seconds flat. No offense to Bentley, but a sub-3-second sedan is about as exciting as it can get on a Monday. For the record, the Edmunds' Straightline Blog reports that the sport sedan's 6.2L supercharged V8 will produce 556 hp at 6,100 rpm and 551 pound-feet of torque at 3,800 rpm. That engine is the LSA, derived from the new Corvette ZR1's LS9 motor and detuned for duty in the CTS-V. Fortunately, the LSA wasn't detuned too much and the '09 CTS-V should destroy its German competition, specifically the BMW M5 with its - can't believe we're saying this - relatively meager 500-hp 5.0L V10.
