The 2003 Toyota Matrix got a bit of a makeover. getting a new grille. front bumper. and taillights. The 2003 Toyota Matrix XR share the same engine with the Corolla. a 1.8-liter. four-cylinder with 130 horses. All-wheel drive knocks the horsepower down to 123 but is still a blast to drive. Fuel economy is about 29-34 miles per gallon. Drivers like the 2003 Toyota Matrix because of its style. dependability. fuel efficiency. and roomy interior. Despite its small size. owners say there is plenty of cargo space.
