A report coming out of Australia indicates Audi is considering launching an entry-level sports car designed to slot beneath the all-new third-generation TT. Small and light, the yet-unnamed sports car could be billed as a pure, back-to-the-basics driver’s car.

While the TT rides on Volkswagen’s modular MQB platform, the smaller sports car will use the MQB Zero platform that is currently being developed and set to be inaugurated by the next generation of the Polo subcompact hatchback.

“I can imagine a smaller car based on the [MQB Zero],” admitted Ulrich Hackenberg, Audi’s development chief, in an interview with CarAdvice.

If launched, expect the yet-unnamed sub-TT model to be offered with several Volkswagen-sourced three- and four-cylinder turbocharged engines. Both front- and all-wheel drive will be available, and a range-topping S-badged model will cater to buyers looking for more performance.

If the rumor is true, the coupe will likely be announced by a thinly-veiled concept at a major auto show before the end of the decade.

In addition to the next-gen Polo and the rumored sub-TT sports car, the MQB Zero platform will spawn the second generation of the Audi A1 subcompact and a small crossover heavily inspired by the Taigun concept that was presented at the 2012 Sao Paulo Motor Show.
