The 2011 Audi TT lacks the extravagant space of a fuller-figured coupe. It's still comfortable enough for a pair of adults to cruise comfortably in, over long distances.
This generation of TT is longer and wider than the original, and it shows in the additional leg and shoulder room. Even up front, the head room is more on the negligible side, with any six-footer set to make contact with the headliner on a regular basis. The back seats found in the TT Coupe are teensy--in the Porsche vein, they're more upholstered luggage trays than anything else, since sliding the front seats forward to accommodate even small people means cramped knees for all.
Storage space is tight in the TT, too. The console and glove box are petite--but on the Coupe, the stow space beneath the hatch glass is actually generous for a car of its size. Since Audi's fabric roof design doesn't require the folding space of a hardtop convertible, the trunk space stays largely intact even when the lid is lowered. The cargo bin nearly doubles in size then the rear seats are folded forward, probably their best and highest use.
Audi's reputation for high-quality materials and fit and finish is evidenced in the TT's tight panel gaps and well-matched plastics. The convertible's roof wards off too much road noise, and it's well-insulated and well-trimmed inside and out.
