2014 was a busy year for TT concepts. Following the all-terrain case studies with the Allroad Shooting Brake and Offroad concepts earlier in the year, Audi went to the Paris Motor Show with something better matched for the TT’s fun-to-drive mission. The TT Sportback used the MQB platform from the Audi A3, but measured nearly a foot longer and a touch wider than the standard TT. The extra doors and rear hatch certainly added interior space, and the concept tore at the asphalt with a 2.0-liter TFSI mill boosted to 400 horsepower (298 kilowatts). For folks wanting a slightly larger, more practical TT, this could've been a serious contender.
