Chevrolet announced the official power rating for the 2009 Corvette ZR1 this week at 638-hp and 604 lb-ft of torque. That’s 18-hp and 9 lb-ft over the original specs released at the 2008 Detroit Auto Show.
Now what’s interesting is the 2009 Cadillac CTS-V shares major components with the ZR-1 such as the supercharged 6.3 liter small-block V8, except with a smaller Eaton compressor. The CTS-V is even known as Caddy’s ZR1 sedan.
Cadillac says that the produces 550-hp and 550 lb-ft of torque. According to InsideLine, if Cadillac is working the same way as Chevrolet is, the 550-hp of the CTS-V will increase to at least 567, an increase of 17.
Cadillac spokesman David Caldwell says, “We’re not trying to hold back part of the story so we can spring a really big number for the final product. But the worst thing we could do is overstate it.”
The 2009 Cadillac CTS-V arrives in showrooms this fall so watch out BMW and Mercedes-Benz, the M5 and E63 AMG are going to get some strong American competition.
