ECOTEC® 2.5L 4-cylinder DI engine with Variable Valve Timing and intake Variable Valve Lift

The ECOTEC® 2.5L engine is part of a family of new, modern 4-cylinder engines engineered for efficiency, spirited response and refined operation. It features the intake Variable Valve Lift (iVVL) technology which allows the lift, duration and timing of the valves to change over a wide range of engine operation. For example, during low-lift mode, the engine pumps out just enough air to meet the driver's needs. When the engine is operating at highway speeds, or under heavy load, the high-lift mode provides additional air to allow the engine to reach its full capability.

• Estimated 195 hp
• 187 lb-ft of torque

3.6L DOHC V6 DI engine with Variable Valve Timing (VVT)This powerplant delivers up to 305 hp @ 6800 rpm and 264 lb-ft of torque @ 5200 rpm.

• DI stands for Direct Injection, which enhances fuel economy¹ and improves vehicle performance
• VVT works by optimizing combustion as well as enhancing low-end torque and high-end power while controlling emissions
