All Audi TT models come with the latest in active and passive safety features: anti-lock brakes (ABS), an electronic stability program (ESP), electronic brake force distribution (EBD), and an electronic differential lock (EDL) to keep the car going in the intended direction and respond to the driver's steering inputs even when he or she isn't working the pedals properly. The 1.8 T 180 comes with traction control (ASR) to make up for its lack of all-wheel drive. Roadsters come with fixed roll bars in polished aluminum finish behind the seats. All TT models include seat-mounted head and chest side airbags and next-generation dual front airbags; three-point safety belts with pretensioners and load limiters; and the LATCH system for child safety seats.

Leather upholstery is standard on all models. Large 17-inch wheels and tires and Xenon high-intensity discharge headlights come standard.

Options include a Papaya Orange paint ($1000); the baseball optic leather interior treatment ($1000); a Premium Package with HomeLink and heated seats ($700); a Bose audio system package ($1200); the power folding top option ($800); 18-inch wheels and tires ($775); a navigation system ($1350); a leather-swathed steering wheel ($275); and a cell phone prep kit ($350).

Upgrades for 2004 include a standard CD-player audio system in base models, standard HomeLink in base models, standard 17-inch wheels and tires for the basic 1.8 T model, height-adjustable sports seats, and xenon high-intensity discharge headlamps with self-leveling and automatic adjustment.
