Mostly known for its Lamborghini tuning propositions, IMSA decided to join in the Audi RS6 craze 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. The result is a 0 to 100km/h (62mph) sprint time of 4.2 sec versus the standard RS6 Avant’s 4.6 sec. 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. -Continued Additional modifications include a lower suspension setting and 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.
