Cadillac has announced the 2014 CTS will be introduced at the New York Auto Show with a twin-turbo 3.6-liter V6 engine.

Described as the "most power-dense six-cylinder engine in the midsize luxury segment," the twin-turbo engine will have an output of 420 bhp (313 kW) and 430 lb-ft (583 Nm) of torque. This equates to 118 bhp (88 kW) per liter which beats BMW's turbocharged 3.0-liter inline-six which produces 100 bhp (74 kW) per liter.

The engine is based on the company's current 3.6-liter V6 but has been equipped with strengthened connecting rods, domed aluminum pistons and an integrated charge air cooler system with low-volume air ducts. There's also direct injection, vacuum-actuated wastegates and twin-turbo chargers which deliver more than 12 pounds of boost.

Thanks to all these modifications, as well as a new eight-speed automatic transmission, the engine will enable the CTS to accelerate from 0-60 mph in approximately 4.6 seconds, before a top speed of roughly 170 mph (274 km/h).

If that sounds like overkill, the CTS will also be offered with a turbocharged 2.0-liter four-cylinder engine that develops 272 bhp (203 kW) as well as a naturally-aspirated 3.6-liter V6 which cranks out 321 bhp (239 kW).

The twin-turbo engine will debut in the CTS this fall and will eventually be offered on the XTS later this year.
