2014 Cadillac CTS and 2014 Cadillac XTS Get New Twin-Turbo V-6 Engine

2014 Cadillac CTS and 2014 Cadillac XTS Get New Twin-Turbo V-6 Engine

By Jeff Youngs, March 19, 2013
Moving up in size--and presumably price--to compete with midsize luxury sedans such as the Audi A6, BMW 5 Series, Infiniti M, Lexus GS, and Mercedes-Benz E-Class, the redesigned 2014 Cadillac CTS debuts at the 2013 New York International Auto Show, and will be offered with a new twin-turbocharged, direct-injection 3.6-liter V-6 engine and an 8-speed automatic transmission when it goes on sale later this year. The new Cadillac Twin-Turbo V-6 will also be offered in the 2014 Cadillac XTS.

Rated to generate 420 horsepower and 430 lb.-ft. of torque, with 90% of peak torque available between 2,500 and 5,500 rpm, the Cadillac Twin-Turbo V-6 is paired with a new 8-speed automatic with paddle shifters that can change gears in 0.3-second when the driver is accelerating hard, according to the automaker. By Cadillac's stopwatch, the 2014 Cadillac CTS Twin-Turbo V-6 can accelerate to 60 mph in 4.6 seconds on the way to a top speed of 170 mph.

Based on the same architecture as the current direct-injection 3.6-liter V-6 engine offered in all Cadillac models, the Twin-Turbo V-6 features new internal components designed to strengthen the engine while enhancing durability, smoothness, quietness, and fuel economy. The automaker says it is the most powerful V-6 engine ever produced by General Motors and is the "most power-dense 6-cylinder engine in the midsize luxury segment," delivering 118 horsepower per liter of displacement. Cadillac notes that its twin-turbocharged 3.6-liter V-6 is more powerful than the turbocharged 4.4-liter V-8 BMW employs in the 550i.

"The new Cadillac Twin-Turbo brings a new dimension of technologically advanced performance to the all-new 2014 Cadillac CTS sedan," said David Leone, executive chief engineer for the CTS. "Delivering power and sophistication, it marks another large step forward in the product-driven expansion of Cadillac."
