A convertible joins the hatchback New Beetle for 2003. All New Beetles have a 4-cyl engine. GL and GLS models have a 115-hp 2.0 liter. GL 1.8T, GLS 1.8T, and GLX models have a 150-hp turbo 1.8. These models are available in both body styles. Available only as hatchbacks, TDI models have a 90-hp turbodiesel, and the top-line Turbo S has a 180-hp turbo 1.8. All come with manual transmission: a 6 speed for the Turbo S, a 5 speed otherwise. All but the Turbo S are available with automatic transmission: a 6 speed with manual-shift capability for convertibles, a conventional 4 speed otherwise. Antilock 4-wheel disc brakes are standard. Traction/antiskid control is standard on the Turbo S and on GLS 1.8T and GLX convertibles; it's optional on other New Beetles.

The GL convertible has a manual folding top, other convertibles a power top; all include a heated glass rear window and rollover bars that deploy if sensors detect an imminent tip. The Turbo S has unique trim, stiffer suspension, and 17-inch wheels; the 17s are optional for GLS 1.8T and GLX models in place of 16s. Also for '03, GLs gain standard power windows and cruise control and optional heated seats. GLS models now include alloy wheels and sunroof. And all models get a rear seat designed for two, not three, occupants. Convertibles have side mirrors with built-in turn-signal lights that VW says will be phased in on other New Beetles.
