Honda has made a number of enhancements to the 2004 Honda S2000. Most importantly, a larger 2.2-liter engine has been fitted. This, along with revised transmission gearing, is meant to improve power delivery. Other changes include updated suspension tuning, 17-inch wheels (16s were the previous standard), upgraded brakes, larger tailpipes and restyled front and rear bumpers with new headlights and taillights. Inside, there's a new center console (with two cupholders and a storage tray) and a bit more shoulder, elbow and hiproom for the driver and passenger. All Honda cars have a new seatbelt reminder system this year.
