Over 500hp likely, and a more distinct look from the regular CTS. BY ALISA PRIDDLE, PHOTOGRAPHY BY KGP PHOTOGRAPHY April 2007 General Motors is laying down the gauntlet. The next-gen Cadillac CTS-V won't be here until the fall of 2008, but, with an anticipated 500 horsepower, it has the BMW M5 squarely in its sights. The next-gen CTS-V “will be at a power level only described as unexpectedly high,” GM vice chairman Bob Lutz tells CARandDRIVER. Sources say we should be prepared for a 25-percent increase on the current car—which means 500 horsepower. And that has us dreaming of the 505-hp, 7.0-liter LS7 V-8 that currently powers the Corvette, although GM types say there are a few possibilities vying to cram themselves into the CTS-V. Meanwhile, having recently driven prototypes of the new CTS-V, Lutz pronounced it “flat-out incredible. I’ve never driven anything like that.” And already he’s talking smack, warning a certain Teutonic competitor that unless the next M5 is substantially better, the CTS-V “will suck the doors off” the competition. The new V is due in the fall of 2008 as a 2009 model. In the interim, enthusiasts must continue to embrace the 2007 CTS-V powered by the 400-hp 6.0-liter Corvette LS2 V-8 engine. With an-all new CTS sedan bowing this year, the ’07 CTS-V, which will stop production in May, will have to bridge the gap until the V makes its triumphant return as an ’09.
