HPerformance recently finished working on a 2014 Audi RS6 Avant which has received several mechanical upgrades.

After unveiling a 500 HP TT-RS duo, HPerformance is back with a modified RS6 Avant which has been fitted with the tuner's 70mm double-pipe exhaust system featuring exhaust valves controllable either pneumatically or electronically through the MMI.

The most important change has occurred under the hood where the V8 4.0-liter twin-turbo has received an ECU remap and a carbon air intake system increasing output to an impressive 700 HP (515 kW) and 860 Nm (634 lb-ft), up from the series 560 HP (412 kW) and 700 Nm (516 lb-ft).

Performance figures have not been released but the hot wagon should be a tad quicker than the stock car which does 0-62 mph (0-100 km/h) in 3.9 seconds and a top speed of 190 mph (305 km/h) when configured with the Dynamic Plus package.

The tuner mentions work has already started on larger turbochargers and customized downpipes which will increase output even further.
