The third generation of the Audi TT was introduced in 2014 at the Geneva Motor Show.
It was developed on the MQB platform used by many other cars in the Volkswagen group.

The original design of the TT was signed by Peter Schreyer in 1994, while he was working for Audi before moving to Kia as head of design. The idea behind the concept was a car with a low seating position, two seats, an engine in the front, and a front- or all-wheel-drive system. The concept remained, the technology evolved.

The TT Roadster featured a new, singleframe, grille with horizontal slats. The four-rings badge was moved on the hood to clear the grille area. The clear-cut headlights incorporated the LED daytime running lights. Despite some curved lines on the bodywork, the headlights were clear-cut in straight edges. There was an option for a full-LED or Matrix-LED lighting system. On the sides, the big wheel-arches broke through the hood gap, emphasizing the big wheels. Unlike its TT sibling, the TTS featured silver door-mirrors, regardless of the color of the car. A pair of twin-oval exhaust came under the rear bumper, with a wide diffuser between them.

Inside, there was a new Audi Virtual Cockpit for the instrument cluster. The big TFT display was used as a screen for the infotainment unit, named MMI. The newest generation was designed together with Nvidia and it used a Tegra 30 graphic processor. The dashboard featured five air-vents with a turbine design. The TT was fitted as standard a set of sport-bucket seats, named S-sport, was on the options list. Two silver safety arches were installed behind the seats.

The 2.0-liter TFSI engine (direct fuel injection, twin-turbocharged) offered 310 hp. It was mated as standard to a 6-speed manual and an option for 6-speed auto.
