It depends on the kind of Matrix that you have. Both the base 2WD model and the 4WD model have a 1ZZ-FE engine that produces roughly 140hp. The 2WD XRS edition has the 2ZZ-GE engine, which produced 180hp in 2003. As a bit of trivia, the 2ZZ-GE engine was co-developed by Toyota and Yamaha and is used in the Toyota Matrix XRS as well as the Corolla XRS, Celica and the Lotus Exige and Elise.
