The German tuners from mcchip-dkr have unveiled a power boost for the Audi S4 Avant. It should be mentioned that the added oomph was obtained via electronic tweaks after remapping the engine’s ECU. As a reminder, the high-performance wagon makes use of a 3.0-liter V6 TFSI engine developing 333 HP (245 kW) and 440 Nm (324 lb-ft) of torque.
After mcchip-dkr worked its magic, the six-cylinder motor is now capable of outputting 422 HP (310 kW) and 514 Nm (379 lb-ft) of torque. The tuner hasn’t released any performance data but the vehicle should be a tad quicker than the standard variant which needs 5 seconds to cover the 0-62 mph (0-100 km/h) sprint before hitting an electronically-limited top speed of 155 mph (250 km/h).

Released in October 2011, the Audi S4 Avant facelift will likely be replaced sometime next year when an all-new A4 is expected to hit the market and will once again be offered in hotter S and RS guises. The S variant will probably be launched several months after the regular model while the range-topping RS could come out in 2016. The entire A4 (B9) family will be lighter than their current equivalents while the design is expected to be mostly evolutionary.
