After applying an engine ECU retune, high-flow air intakes and a new sports exhaust system, engineers were able to boost output of the RS6’s twin-turbo V10 engine to 650hp (485kW) and 577lb-ft (780Nm) of torque. With the extra power on board, the IMSA RS6 will sprint from 0-100km/h in just 4.2 seconds, pass 200km/h in 13.8 seconds, and reach an unrestricted top speed of 300km/h.
New springs lower the car by 25mm and give it a slightly firmer ride to improve handling. There’s also a set of 20in forged aluminum alloys wrapped with 275mm rubber, and uprated brake discs measuring 14in up front and 13.8in in the back.
IMSA also recently launched a new power and styling package for the Lamborghini Gallardo LP560-4, which you can read about by clicking here. For RS6 fans, check out the latest tuning kits from fellow German tuners B&B, MTM and ABT Sportsline in our previous stories.
