The Audi RS4 aims to move up a league with ABT, alongside its 530 CV

When something is good, it is hard to make it very good, but the German tuner ABT has set out to give the Audi RS4 even more shine, so that it stands out with the “+” badge on its rear. The four-ring estate has once again been handled by ABT, but this time with a goal somewhat more complex than simply improving its mechanics and styling: making it even more exclusive. To do so, the fellow German tuner has decided to launch a limited run of this RS4 onto the market, with the aim of offering a more special vehicle in every sense.

As is customary for ABT, both the styling and the mechanics have undergone a series of significant changes. As a result, we find a Audi RS4 that is much more rebellious and wild, which seeks to leave behind its estate-car status with sports-car performance and enter a higher league, where it competes head-to-head with high-flying vehicles and its bigger brother, the RS6.

A radical look that exalts the RS DNA

ABT is also known for offering, alongside its creations, a styling that matches the mechanical upgrades they receive, and the Audi RS4+ is no exception. At first glance, the front end goes fairly unnoticed compared with the factory version, apart from a new, more aggressive splitter, but we quickly notice significant changes both on the side and at the rear of the four-ring estate.

The first thing that catches our attention is a set of new, custom-designed 20-inch wheels, which seek to bring out an even more sporting character. However, it is at the rear where we find considerable modifications, the first being a new spoiler crowning the rear of the Audi RS4. In turn, this is complemented by a new diffuser finished in carbon fibre, which houses four exhaust outlets instead of the two oval ones characteristic of the RS family of Audi.

Up to 530 CV of power to fly

The German tuner has managed to squeeze even more out of the already well-known twin-turbo V6 engine that powers the Audi RS4. As standard, this 2.9-litre twin-turbo V6 produces 450 CV of power and 600 Nm of torque, figures that catapult the four-ring estate to 100 km/h in just 4.1 seconds, a time complemented by a top speed limited to 250 km/h.

However, ABT, not one to sit idle, has decided to do what it does best: extract every last drop from the powertrains that pass through its hands. Thanks to an improvement in the engine’s electronic management, the new Audi RS4 is able to deliver 510 CV of power and 680 Nm of torque. But that is not all, as the tuner has also thought of its more hardcore customers, who can enjoy a new power level that sits at 530 CV, a figure that dangerously approaches that of much larger vehicles.

It will be at the next Geneva Motor Show that the German tuner premieres the Audi RS4+, a limited edition of which only 50 units will be produced. For now we do not know the outlay that ABT’s closest clients will have to make, but considering the RS4 standard model has a starting price of 96,900 euros, it is easy to see how this tuning package will push that figure comfortably into six figures.
