Following a confirmation from earlier this month, Audi has unveiled the 2015 TT Roadster and TT S Roadster ahead of their public debut programmed for next month at the Paris Motor Show. As expected, both cars look just about the same as their fixed roof siblings but come with a power-folding fabric roof that can be had with a black, jive or titanium gray finish. Opening or closing the roof takes approximately ten seconds and it can be done at speeds of up to 31 mph (50 km/h).
Compared to its predecessor, the roof on the open-top TT is now 3 kg (6.6 lbs) lighter as a result of using magnesium and aluminum in its construction. The vehicles ride on Volkswagen Group’s MQB platform that mixes up high-strength components with aluminum, thus allowing the base TT 2.0 TFSI Roadster weigh only 1,320 kg (2,910 lbs).
The 2015 Audi TT Roadster will be offered with a choice of two four-cylinder, 2.0-liter turbocharged engines. The first one is a TFSI unit developing 230 HP (169 kW) and 273 lb-ft (370 Nm) while the other is a TDI rated at 184 HP (135 kW) and 280 lb-ft (380 Nm).
There’s also the 2015 Audi TT S Roadster which makes use of an uprated four-cylinder 2.0-liter TFSI developing 310 HP (228 kW) and 280 lb-ft (380 Nm). This allows the TT S Roadster to cover the 0-62 mph (0-100 km/h) sprint in 4.9 seconds on its way to an electronically-governed top speed of 155 mph (250 km/h).
