With much of the Honda line-up revised in past years, the majority of the product range maintains familiarity for 2004. On the 2004 Honda Accord, XM Satellite radio is now a factory-installed option. The 2004 Honda Element expands with a mid-range LX trim level. Receiving the most significant changes in 2004 is the Honda S2000 sport roadster. Still known as the S2000, the 2004 version of the two-seater is now powered by a 2.2-liter engine. Other improvements found on the revised Honda S2000 are restyled headlights as well as LED taillights and the standard equipment of 17-inch wheels.
