Audi tuning specialist ABT Sportsline has revealed its latest upgrade package for the RS4 Avant, handing the hot wagon a bump in power and an aerodynamic kit.

The RS4’s twin-turbo 2,9-litre V6, which pushes out 331 kW and 600 N.m of torque as standard, has been fitted with an in-house developed ABT Power engine control unit and a special air-intake cover. This brings the power up to 375 kW and 660 N.m, which the tuner says results in a 0-100 km/h time of 3,9 seconds (some two-tenths quicker than standard).

Optionally, customers can request the ABT Power S upgrade for the RS4-S, which increases the peak outputs to 390 kW and 680 N.m. Here, top speed increases to 300 km/h.

The engine upgrade is joined by a stainless-steel exhaust system with four 102 mm carbon-fibre tailpipes. The wagon's handling is tweaked thanks to the fitment of a set of height-adjustable suspension springs and anti-roll bars on both axles.

Adding to the superwagon’s visual presence is ABT’s Aerokit. A front lip add-on with an RS4-S logo, front blades with wheelhouse ventilation, a CFRP rear spoiler and a diffuser are included in the package. The design scheme is rounded off with a set of 21-inch ABT Sport GR alloy wheels finished in gloss black.

In the cabin, the RS4-S has been kitted out with integrated entrance lights, branded floor mats and door sills, a custom stop-start switch cap, a gear-shift knob cover and seat upgrades with ABT and RS4-S logos.
