After showing the Audi TT RS-R Coupe in Geneva earlier this year, ABT Sportsline has now applied similar updates to the Roadster as well. 

Just like its fixed roof sibling, the TT RS-R Roadster benefits from the power bump that makes the 2.5-liter five-cylinder petrol engine deliver 500PS (493hp) and 570Nm (420lb-ft) of torque. 

With the additional 100PS (99hp) over the stock version, the convertible now needs 3.4sec for the 0-100km/h (62mph) sprint, according to the tuner, which makes it 0.1sec faster than the 540hp version of the Audi R8, and 0.3sec quicker than the stock TT RS Coupe.
