Audi debuted the interior design of its new TT model at the Consumer Electronics Show (CES) show at Las Vegas with an emphasis on the latest infotainment and communications technology that will be used by the new model. The new TT cabin is a driver-focused interior which combines traditional design references, high-quality materials and the latest in-car electronics. The design does not feature a separate infotainment screen and instead features all the infotainment data and graphics on a single all digital instrument cluster contained within the main instrument binnacle.

Infotainment functions are displayed to the driver via the latest version of Audi's MMI system, which has been redesigned to improve functionality and user experience, with the system operating like a smart phone, with text search functionality as well as zoom and scroll functions accessed via the MMI touch interface. In terms of the wider interior design the new TT interior will feature round ventilation nozzles prominently, with temperature and air-conditioning controls situated in the centre of the nozzle itself rather than on a separate panel.
