Cadillac has unveiled a new engine that will be used for the 2014 CTS sedan. The engine is a twin-turbo V-6 producing 420 hp and 430 pound-foot of torque. General Motors says that this is the most power dense six-cylinder engine in the segment producing 118 hp per liter.

The new twin turbo V6 will also be the first twin turbo engine for Cadillac and the first be paired with an eight-speed automatic transmission. The V-6 engine uses a smaller pair of turbochargers combined with an efficient charge air cooler to reduce turbo lag and provide immediate power delivery. The engine displaces 3.6-liters and GM says that 90% of engines peak torque is available from 2500 RPM up to 5500 RPM.

That broad torque curve will give drivers of the vehicle a feeling of available power in almost any driving condition. Cadillac says that the CTS sedan equipped with the optional twin turbo V-6 engine will be able to reach 60 mph in 4.6 seconds. The vehicle will have a top speed estimated to be 170 mph.

The 2014 CTS sedan is set to debut in the US this fall. GM says that almost every component in the V-6 engine is new including stronger connecting rods, machined aluminum pistons, and lots more. The turbochargers produce over 12 pounds of boost. The 2014 CTS will also be available with a naturally aspirated 3.6-liter V6 and a 2.0-liter turbocharged engine.
