B&B Automobiltechnik has launched a new upgrade program featured power enhancements up to 610hp and 600 Nm for the Audi R8 V10 Spyder.

According to the tuning company, the power increase is attributed to a special racing exhaust system. The Audi R8 V10 Spyder by B&B can hit 62 mph (100 km/h) in 3.5 seconds and reaches a top speed of 328 km/h.

B&B is also offering carbon air filter and a remap of the electronic injection code fields. There are also a set of 19 or 20 inch rims finish the modifications and sport suspension that lowers the car by 20mm front and 25mm rear.

They can also tweak the R-Tronic gear shift and this means that the transmission is faster than the one found in the Audi R8 GT.
