The Ecotec 2.2L I-4 engine used in drag racing versions of the Cavalier and Sunfire can generate up to 1,000 horsepower while using mostly production-based components. These front-wheel drive race cars showcase the potential of the Ecotec engine. The production version of the Ecotec puts out 144 horsepower and 155 pound-feet of torque using lightweight aluminum construction and dual overhead camshafts with 4 valves per cylinder. The modular design of the Ecotec makes it suitable for a variety of applications.
