"While Cadillac is trumpeting its new twin-turbocharged 3.6-liter V-6 engine today as the CTS&amp;#039;s new top-of-the-line motor (in anything less than the CTS-V, of course), the real news about today&amp;#039;s announcement relates to the smallest Cadillac. According to our sources, the upcoming Cadillac ATS-V will almost assuredly be powered by a version of this turbo six, which Cadillac says is the most power-dense in the segment. With 118 horsepower per liter, that&amp;#039;s worth crowing about: that&amp;#039;s a better figure than even BMW&amp;#039;s 3-liter turbo inline-six. In CTS trim, Cadillac claims 420 horsepower and 430 lb-ft, with peak torque available over a broad RPM range. That gives the CTS equipped with this engine a claimed 0-60 mph time of around 4.6 seconds. Considering that a regular rear-drive 3.6-liter ATS is already about 500 lbs lighter than a similarly equipped CTS, even without an increase in power this motor should make the ATS-V very, very quick. Lots to be excited about in this particular powertrain announcement "^^<http://www.w3.org/2001/XMLSchema#string>
