Following in the footsteps of so many other tuners, Sportec has announced that it too has released a sport package for the Audi RS6 Avant. The Swiss tuning firm’s Stage 1 performance kit (apparently Sportec will present more powerful kits in the near future) includes a reprogrammed ECU that adds 70 HP to the RS6’s 5.0-liter bi-turbocharged V10 raising total output to 650 HP at 6,300 rpm. Maximum torque has also been lifted to 740 Nm (546-lbs/ft) at 2,500-4,500 rpm. -ContinuedSportec says that with the Stage 1 performance kit the RS6 Avant can accelerate from standstill to 100 km/h (62mph) in 4.4 sec versus the standard car’s 4.6 sec and go on to a top speed of 305 km/h or 190mph. Buyers can also opt for a lowering kit and a set of 20 or 22-inch lightweight alloy wheels.
