Impressive as the 426 kW and 650 N.m of torque produced by the Audi RS6′s twin-turbocharged V10 engine may sound, there’s always room for improvement. APS, the UK importer of the Swiss tuning brand Sportec, has launched two upgrade packages for the sedan and estate (Avant) variants of the RS6.

The first stage adds a remapped ECU boosting output to 485 kW at 6 300 rpm, coupled to 740 N.m of torque between 2 500 – 4 000 rpm. With this kit, the APS Sportec-prepped RS6 reaches 100km/h in 4.4 seconds, while top speed is limited to 305 km/h.

For those with spicier tastes, APS Sportec offers the Stage Two conversion that consists of a reprogrammed ECU, complete with performance optimisation of fuelling, ignition and boost parameters, in parallel with the fitment of emissions compliant sports catalysts. The result is 522 kW at 6 200 rpm and 800 N.m between 3 000 – 6 200 rpm, which translates to a 0 – 100km/h sprint time of 4.2 seconds and a limited top speed of 305 km/h (same as the Stage One package).

APS added that a full range of Sportec Audi RS6 enhancements, including alloy wheels, braking and suspension packages, will be launched over the coming months.
