2014 Cadillac CTS will come with a 420-hp, twin-turbo thump

We'll see Cadillac's redone 2014 CTS sedan next week during the New York Auto Show, and while images of the machine's body have not been released, Cadillac's plans for beneath the skin have. The standard V-6 remains, but a brand new twin-turbo 3.6-liter V-6 arrives, bridging the gap between the top-line CTS and the mighty CTS-V.

The new motor boasts a massive 420 hp and 430 lb. ft of torque, and will burst to 60 mph in an estimated 4.6 seconds. The brutish powerplant will be mated to an eight-speed automatic gearbox, replacing the six-speed in a quest for improved fuel efficiency.
