Audi is ushering in a new RS4 platform that is sure to impress both journos and consumers. The revised A4 has proven to be a worthwhile change that not only betters the model's dynamics but its overall package as well, meaning that the pumped up version is looking up from here. With the RS4 being one of the brand's most noteworthy cars in recent memory, the Avant variant is especially coveted. This video shows a prototype of the performance estate blasting its way through the Green Hell, carving the steep corners with composure and tire squeal aplenty. 

Although the car is covered up with swirls and an eye-tricking wrap, we can start to make out the generalities of the RS4's design. Widened arches present of course, helping to set the pace for the rest of the car's aggressive look, fitting the larger rubber to aid the Avant's performance. It takes a few cues from its recently introduced big brother, the S5, with a gaping grill and cut outs on each side to display a mean front fascia. A raked roofline completes the profile, adding a swept back appearance to the go-fast family hauler.

You can hear the engine growl with a particularly throaty note. It's rumored that the RS4 will feature a 2.9L twin turbo V6, much like that in the Porsche Panamera. Power figures are a bit shaky, though we've heard that the engine could produce around 450 horsepower, making the Audi an especially tough competitor to other German performance wagons.

The car is expected to make its official debut at the Frankfurt Motor Show later this year. Until then, this quick clip of the car ripping through the Nordschleife will have to suffice.
