Details and pictures are starting to roll out. I have driven the auto version of this engine in the CTS and XTS V-sport model and wasn’t all that impressed. Maybe the manual and weight reduction of the ATS will help it out.
3.6TT with 450 horsepower and 445 pound-feet of torque. In glorious news for driving enthusiasts everywhere, that potent mill will be available with either a six-speed manual or eight-speed automatic.
According to R&T, the engine has a heap of high-performance tech to let it make the extra ponies, including titanium connecting rods, two water-to-air intercoolers, titanium turbines for the turbos and an additional radiator dedicated to cooling the gearbox and electronically locking differential. Keeping it all planted are a set of Michelin Pilot Super Sport tires, and a suspension with 50 percent more roll stiffness. Weight at 3,600 lbs
