It has been 3 years since the RS4 got off Audi's production line but today we can indulge ourselves once again in the roar of a V8, shelled by a familiar body – It's the new Audi RS4. The resurrection kicks off with an Avant version which is here to show it's rivalries what's what.

The RS4 is back with a bang as it gets the powertrain usually found in the RS5 Coupe – a hand-built 4.1 liter plant, producing 450 PS at 8,250 rpm and 430 Nm of torque from 4,000 to 6,000 rpm. In true RS tradition, that power goes trough a permanent Quattro AWD system. The 'permanent' term however, should not scare you off as the Quattro in the latest RS4 is exceptionally flexible – it incoroprates a self-locking crown-gear centre differential that allows up to 85 percent of the power to go to the rear axle or up to 70 towards the front wheels. By default, one would find that the power bias ratio is 40:60 in favor of the back wheels. So for the people who like to travel sideways everywhere that is a relief.

The whole power thing translates into a time of 4.7 seconds for the 0 to 60 mph sprint and a top speed of 174 mph (limited to 155 mph). Stunning performance, keeping in mind that this estate returns 25.7mpg on the combined cycle.

Compared to the standard A4, the RS4 is 20 mm lower thanks to the truly complex suspension - a five-link set-up at the front and a self-tracking trapezoidal-link rear assembly. We don't know what all that means but chances are its beneficial. The power steering is clever too. It has a conscious mind that takes into account the current speed of the car to determine the steering firmness.

The car sits on 19-inch (20-inch optional) wheels wrapped in four 265/35-series tires. The 10-spoke design of the wheels are rather revealing and it's not like the Audi hasn't got anything to hide. We are talking about internally vented wave disc brakes – an innovation in stopping power as the brakes are around 3 kg lighter (in total weight) and more heat-efficient due to their "wave" outer, perforated contour.

Inside, black is the predominant finish with occasional carbon inlays and chrome clasps lining the switches and buttons. One would also find that the front sports seats are heated and that the driver information system has an RS menu with a lap timer.

There are tons of other optional extras that might be worthwhile ticking – the Dynamic Ride Control ensures even more stability at high speeds and sharp bends and a sports exhaust system for that kid in everyone of us.

Prices for the Audi RS4 are yet to be released and hopefully we'll see the arrival of a sedan version so that everyone is happy. In the mean time do not hesitate to look around in the RS4 gallery.
