The Golf is available in either two-door or four-door bodystyles, and the trim levels include a GL on the two-door and GL or GLS on the four-door. Two different engines can be had, a 115-hp 2.0-liter four-cylinder gas engine, or a 100-hp 1.9-liter four-cylinder TDI diesel engine (four-door only). A five-speed manual is standard, the gas engine offers an optional four-speed automatic, and the TDI can be optioned with a five-speed automatic with Tiptronic. All models include power windows, mirrors and locks, keyless entry, 15-inch wheels, air conditioning, cruise control and an eight speaker sound system with cassette and CD players. The GLS adds a standard power sunroof, Monsoon audio system and alloy wheels. Safety features include six airbags, anti-lock brakes, front safety belts with pre-tensioners and load limiters, anti-intrusion side door beams, and a steering wheel which is deformable/collapsible upon impact. Electronic Stabilization Program (ESP) with brake assist is optional on all models. The Golf is unchanged for 2005 after the numerous updates for the 2004 model year.
