As the Aerio is a recent introduction to the market, there aren't that many changes for 2003. Suzuki has bumped the horsepower up by four to 145 and nudged the torque up one pound-foot to 135. Other additions include integrated cruise control buttons on the steering wheel, a three-point seatbelt and headrest for rear center seat and a new cloth design. The GS and SX models drop the rear-seat armrest, get a six-disc in-dash CD player and have the optional all-wheel-drive available.
