Cadillac CTS

The next epoch in Cadillac’s renaissance begins with the all-new 2008 CTS – the next generation of the popular luxury sport sedan that is intended to challenge the world’s best.

The 2008 Cadillac CTS has a new 3.6L direct-injection V-6 engine. More power while maintaining fuel economy and lowering emissions sounds like a daunting engineering challenge, but CTS delivers via gasoline direct-injection technology. A cousin to the system favored by the latest diesel engines, direct-injection technology delivers fuel more precisely to increase the efficiency of combustion. This means less fuel is consumed – and lower emissions created – compared to conventional combustion systems doing the same work. With the CTS’ 3.6L V-6, this means more power, with 304 horsepower (227 kW) and 277 lb.-ft. (370 Nm) of torque, no loss of fuel efficiency and a 25-percent drop in cold-start hydrocarbon emissions.

For the first time, the 2008 Cadillac CTS offers the choice of rear-wheel (standard) or all-wheel drive. CTS also offers the choice of a six-speed manual and automatic transmission. Inherited from Cadillac’s STS-V, XLR-V and Escalade, the six-speed automatic features driver shift control, which enables on-demand clutchless manual shifts.

The 3.6L direct-injection engine will be the top-level engine option for the 2008 CTS, joining the existing 2.8L V-6 and 3.6L V-6. Designed to operate with regular unleaded gasoline, the new 3.6-liter direct-injection V-6 produces power similar to many V-8 engines, but with much better fuel economy. With direct injection, fuel is delivered directly to the combustion chamber to create a more complete burn of the air/fuel mixture. Less fuel is required to produce the equivalent horsepower, especially at normal cruising speeds, of a conventional port-injection combustion system.
