The 3.5-liter VTEC V-6 engine produces an impressive 280 horsepower and 254 lbs.-ft. of torque (both SAE net), while achieving an EPA Fuel Economy Rating2 of 19 in the city and 28 on the highway.
- VTEC, which stands for Variable valve Timing and Electronic lift Control, enables the intake valves to open deeper and longer when the engine reaches approximately 4500 rpm to enhance airflow and allow the TLX to continue to build horsepower at levels where other engines may run out of steam.
- All-aluminum construction, a hollow camshaft, and other weight-saving measures keep the larger engine lighter for better handling.
- The Drive-by-Wire? throttle system provides a precise balance of smooth and responsive operation by adjusting throttle sensitivity to varying driving conditions.
- Fuel efficiency is enhanced by lower-friction piston rings and the ability to run on lower viscosity oil and transmission fluid.
