Celebrating a modern day classic, Audi will unveil a custom RS4 Avant model at the Geneva Motor Show with modern day performance and retro style.

Build to commemorate 20 years since the launch of the RS2, the RS4 Avant Nogaro is powered by one of the few naturally aspirated engines left in the Audi lineup – and perhaps the best – a 4.2-liter V8 that delivers 450 hp at a rev-happy 8250 rpm. Torque comes on strong from 4,000 rpm with 317 lb-ft available, enabling a 0-60 mph time of 4.7 seconds and a top speed of 174 mph.

A surprisingly un-retro move, the Nogaro won’t be offered with a six-speed manual, but rather the brand’s new 7-speed S-tronic dual-clutch unit.

With standard quattro all-wheel drive, power is distributed 40:60 front-to-rear, though up to 70 percent of the torque can be shifter forwards for maximum grip, or up to 85 percent to the rear wheels for serious performance driving. An optional sport differential that splits the power between the left and right rear wheels is also available.

A tribute to the RS2, the original Audi RS model, the RS4 Nogaro gets its name from the paint color used on the 1994 car. Additional retro-inspired flares include gloss black used for the grille, window trim and roof rails. An RS sports exhaust also gets a dark black finishing.

Other exterior highlights include 20-inch wheels with red-painted brake calipers with RS emblems, while front carbon ceramic brakes can be ordered as an option.

Perhaps the most dramatic styling update on the Nogaro model is on the inside with custom blue leather and Alcantara on the seats and door inserts, with blue stitching on the interior. There’s even blue threads running through the carbon fiber inserts. For those with more subtle tastes, Audi will also offer an all-black option.

The RS4 Avant Nogaro will go on sale in Europe soon, with no plans to be offered in North America.
