IMSA Audi RS6

IMSA is mostly known for its Lamborghini tuning programs, but now IMSA decided to join in the Audi RS6 tuner war that has hit the German tuning scene by presenting a souped-up version of the range-topping Avant model.

Modifications to the engine that include a remapped ECU and a new exhaust system boost the 5.0-liter V10’s output to 650 HP (from 580 HP) while torque has also been increased to 745 Nm or 550-lbs/ft.

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. According to IMSA, the outrageously powered station wagon can accelerate from standstill to 200 km/h (125 mph) in just 13.8 sec and on to a top speed of over 300 km/h or 187 mph.

Additional modifications include a lower suspension, with new springs lowering the car by 25mm and give it a slightly firmer ride to improve handling. A set of ultra light 20-inch alloy wheels derived from the company’s tuning kit for the Gallardo that are wrapped around 275 performance tires.
