The new 2013 Audi RS4 Avant is powered by the high-revving, normally aspirated V8 engine with 4,1633 cc displacement produces 450 hp (331 kW) at 8,250 rpm and peak torque of 430 Nm (317.15 lb.-ft) available from 4,000 to 6,000 rpm. The V8 engine accelerates this new Audi car from 0-100 km/h (62.14 mph) in 4.7 seconds.
The Audi RS4 Avant comes standard with quattro permanent all-wheel drive. The heart of this system is the crown-gear center differential. This compact and lightweight component can vary the distribution of power between the front and rear axles immediately, smoothly and over a wide range, with up to 70 percent flowing to the front or as much as 85 percent to the rear. The default 40:60 ratio of the rear-biased configuration ensures sporty handling.
The exterior of the new Audi RS4 Avant highlighted by the hexagonal single-frame grille is set in a frame with a matte aluminum-look finish; its honeycomb insert is finished in high-gloss anthracite. LED daytime running lights encircle the xenon plus units like a clasp in the wedge-shaped headlights. The air flows through large openings divided by crossbars and embedded in a distinctive bumper featuring a splitter edge like on a race car.
When viewed from the side, the chiseled side sill caps and flared wheel wells catch the eye. The flared rear side elements with sharp horizontal upper edges are a nod to that all-wheel drive pioneer from 1980, the Audi quattro. The side mirror housings and trim strips have a matte aluminum-look finish, and a discrete roof spoiler at the back ensures the necessary downforce.
The distinctive bumpers and the two oval tailpipe caps of the dual exhaust system dominate the rear end and are integrated into an upturned diffuser. Audi also offers a sport exhaust system with a voluminous sound and black caps. Elegant light strips adorn the LED rear lights.
The Audi RS4 Avant is 20 millimeters (0.79 in) longer and 24 millimeters (0.94 in) wider than the A4 Avant, but 20 millimeters (0.79 in) lower. A choice of eight colors is available: one solid and one metallic finish, four pearl-effect colors and the two specially pigmented crystal-effect colors, Prism Silver and Panther Black. The extensively clad underbody integrates air vents for the seven-speed S tronic and the front brakes.
Inside, the Audi RS4 Avant is clad completely in black, with the exception of the roofliner, which is optionally available in Moon Silver. Chrome clasps subtly accentuate switches and control elements. Carbon inlays are standard, with brushed matte aluminum, Aluminum Race, black piano finish or a light stainless steel mesh available as options.
The standard heated front sport seats with integrated headrests are power adjustable and covered in a combination of black leather and Alcantara. Fine Nappa leather in either Black or Moon Silver accentuated with Stone Gray piping is optionally available. Other options include bucket seats or luxurious, climate-controlled deluxe seats with a ventilation function. The thick ring of the leather multifunction sport steering wheel is flattened at the bottom, and the shift paddles mounted on the back of it sport an aluminum-look finish.
The new Audi RS4 Avant will available in fall 2012 with a base price of €76,600 in Germany.
