The 2011 Chevrolet Traverse delivers a robust and satisfying combination of power, efficiency, ride and safety. The driving experience is supported by a sophisticated, 3.6L DOHC V-6 that features variable valve timing and gasoline direct-injection technology. It is designed to provide excellent power and efficiency that translates to usable, power-on-demand performance and what is expected to be the best highway fuel economy in the segment. The engine is backed by a fuel-saving six-speed automatic transmission that channels power to a responsive, four-wheel independent suspension. Great power and fuel economy
The 3.6L engine?s direct-injection technology helps produce power similar to many V-8 engines and uses regular unleaded gasoline. The Traverse is rated at an estimated 286 horsepower (213 kW)* and 255 lb.-ft. of torque (345 Nm)* with dual exhaust (281 hp/210 kW* and 253 lb.-ft./343 Nm* with single exhaust) ? but delivers better-than-expected fuel economy. Ninety percent of the engine?s peak torque is available from approximately 2,500 rpm to more than 6,000 rpm.
With direct injection, fuel is sprayed directly into the engine cylinder, where it is mixed with air. As the fuel vaporizes in the cylinder, the air and fuel mixture is cooled. This enables the use of a higher compression ratio in the combustion chamber, which improves engine performance and efficiency. Less fuel is required to produce the equivalent horsepower ? particularly at normal cruising speeds ? of a conventional, port-injection system. Also, the use of unique pistons with the direct-injection system helps reduce cold-start emissions by 25 percent.
