Naturally, with the new RS design language, the new RS 4 Avant looks much more aggressive than the A4 Avant. Features include the optional matrix LED headlights with darkened bezels, gloss black, matt aluminum and carbon styling packages for the sill, mirror housings, and the front and rear bumpers. Buyers can go for gloss black and carbon styling for the Audi rings and the RS logo. The RS badges can be omitted completely for a more understated look.
The roof rails are finished in matt black as standard. The RS-specific roof edge spoiler and the diffuser insert, as well as the chrome tailpipes of the RS exhaust system, add more style to the rear. Buyers have the option of RS sport exhaust system with black tailpipe trims.
The new RS 4 Avant rolls off the factory with 19-inch forged aluminum wheels. Various 20-inch designs are available, including a new five-arm wheel finished in matt bronze. As standard, the steel disc brakes measure 375 mm (14.8 in) at the front and 330 mm (13.0 in) at the rear axle. The six-piston brake calipers with RS logos are painted in black, or optionally in red. Buyers can go for RS ceramic brakes with 400 mm perforated discs at the front. The calipers are available in red, gray and blue.
As standard, the new RS 4 Avant gets RS sport suspension that lowers the vehicle by 7 mm compared to the S4 base model with sport suspension. The RS sport suspension plus with Dynamic Ride Control (DRC) is optional; this integrated roll and pitch stabilizer consists of a special damper system that counteracts the movements of the body. The damper response can be adjusted in 3 levels.
The cockpit of the new RS 4 Avant features a black theme. LED light guides trace the contours of the doors and the center console – doing so in up to 30 different colors in combination with the optional ambient lighting package.
RS sport seats with optional honeycomb pattern
RS design package adds RS logo on the center console, armrests, seat belts and floor mats. The steering wheel, selector lever and knee pads are all covered in Alcantara with red contrasting stitching. In addition to the red, the extended RS design package now also offers accents in gray.
Other equipment includes Audi virtual cockpit with special RS displays, 10.1-inch MMI touchscreen infotainment system, flat-bottom RS multifunction steering wheel with the new RS Mode button, and new aluminum shift paddles that are larger than before. The optional head-up display also provides some RS-specific information including the shift light display.
RS-specific dynamic steering is available as an alternative to the standard electromechanical power steering. Audi says that the dynamic steering varies the steering ratio by up to 100 percent based on the driving speed, steering angle and selected mode in the Audi drive select handling system.
As for the business end of the story, the new RS 4 Avant is powered by a 2.9-litre TFSI twin-turbo V6, producing 331 kW (450 hp) and 600 Nm (442.5 lb-ft) of torque between 1,900 to 5,000 rpm. Audi claims a 0 – 100 km/h acceleration time of 4.1 seconds. The RS dynamic package increases the electronically limited top speed from 250 to 280 km/h (155.3 to 174.0 mph).
An 8-speed tiptronic transmission sends power to all four wheels via quattro permanent AWD system. The mechanical center differential directs 60 percent of the torque to the rear axle and 40 percent to the front. In the case of slippage at one axle, most of the power is automatically redirected to the other axle – up to 70 percent to the front or up to 85 percent to the rear axle.
