Cadillac Twin-Turbo Debuts in All-New 2014 CTS Sedan

Cadillac, Mar 18 2013 - V6 engine and eight-speed transmission – firsts for the brand and signature features of the all-new 2014 Cadillac CTS midsize luxury sedan debuting next week at the New York Auto Show.

420 horsepower (313 kW) / 430 lb-ft of torque (583 Nm) – SAE certified:
- Most power-dense six-cylinder in segment at 118 hp/liter
- Cadillac’s first twin-turbo engine and eight-speed automatic transmission

Cadillac Twin Turbo

The Cadillac Twin-Turbo V-6 is the most power-dense six-cylinder engine in the midsize luxury segment – a 3.6L with 118 horsepower per liter (88 kW/liter) – and the eight-speed automatic enhances fuel economy and acceleration over a six-speed automatic.

“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. “Delivering power and sophistication, it marks another large step forward in the product-driven expansion of Cadillac.”

Rated at an SAE-certified 420 horsepower (313 kW) and 430 lb.-ft. of torque (583 Nm), it is the most powerful V-6 ever from General Motors. It also has 15 percent greater power density than BMW 535i’s turbocharged 3.0L six, which is rated at 300 horsepower (223 kW), for a ratio of 100 horsepower per liter (74 kW/liter) – and even the BMW 550i’s TwinPower 4.4L V-8, rated at 400 horsepower (298 kW), or 91 horsepower per liter (68 kW/liter). Power density is a measure of efficiency for an engine’s size.

A pair of smaller turbochargers and an efficient charge air cooler help provide more immediate power delivery. Additionally, approximately 90 percent of the 3.6L Twin-Turbo’s peak torque is available from 2,500 rpm to 5,500 rpm, giving the engine a broad torque curve that customers will feel as strong, willing power in almost all driving conditions, such as accelerating or overtaking traffic on the highway.

Those features help the new CTS sedan reach 60 mph from a standstill in an estimated 4.6 seconds and achieve an estimated top speed of 170 mph (274 kph).

The new Cadillac Twin-Turbo will expand the performance envelope of the upcoming 2014 CTS midsize luxury sedan, launching this fall in the United States. The engine will also will be offered in the 2014 XTS large luxury sedan this fall. www.gm.com/content/gmcom/home/brand_landing_pages/cadillac.html
