General Motors Co. said Monday it will offer a twin-turbo V-6 engine and eight-speed transmission — both firsts for the automaker — in its all-new 2014 Cadillac CTS available this fall.

The new 3.6-liter engine can achieve 420 horsepower and 430 foot-pounds of torque, and has been certified as having the highest output in a V-6 engine in General Motors' history, said Richard Bartlett, assistant chief engineer for the engine.
 
"The new Cadillac twin turbo brings a new dimension of technologically advanced performance to the all-new 2014 Cadillac CTS sedan," David Leone, a GM executive chief engineer, said in a statement. "Delivering power and sophistication, it marks another large step forward in the product-driven expansion of Cadillac."
