Under the hood of the Audi RS 4 Avant Nogaro selection operates a high-revving V8 naturally aspirated engine with a displacement of 4,163 cc. The 4.2 FSI delivers 331 kW (450 hp) of power output at 8,250 rpm, with peak torque of 430 Nm (317.15 lb-ft) available between 4,000 and 6,000 rpm. The resonant eight-cylinder engine accelerates the anniversary model from 0 to 100 km/h (62.14 mph) in 4.7 seconds and takes it to a governed top speed of 280 km/h (173.98 mph). Its combined fuel consumption is 10.7 liters per 100 kilometers (21.98 US mpg) – for a CO2 equivalent of 249 grams per kilometer (400.73 g/mile).
With its high efficiency and tall top gear, the standard seven-speed S tronic also contributes to fuel efficiency. The driver can let the lightning-fast dual-clutch transmission shift operate automatically or change gears themselves using the selector lever or the steering wheel paddles.
The core of the quattro permanent all-wheel drive is the self-locking crown gear center differential. The compact and lightweight component distributes torque at a default ratio of 40:60 between the front and rear axles. This ratio can be broadly varied as required – with up to 70 per cent of the power going to the front and a maximum of 85 per cent to the rear. The crown gear center differential cooperates with the wheel-selective torque control, which makes handling at curve limits even more dynamic through selective, small brake impulses. Audi offers the sport differential as an optional addition that actively distributes the power between the rear wheels.
The standard equipment of the Audi RS 4 Avant Nogaro selection also includes the Audi drive select dynamic driving system. This system allows variation between three modes – comfort, auto and dynamic – for the characteristics of the electromechanical power steering, the seven-speed S tronic, the accelerator and the RS sport exhaust system. And if the car is equipped with Audi MMI navigation, there is also a fourth mode – individual – that can be configured by the driver.
Besides the sport differential, two further optional elements are available for Audi drive select. The dynamic steering varies the steering ratio depending on the speed and countersteers with small impulses at curve limits. The RS sport suspension plus with Dynamic Ride Control (DRC) equalizes the roll and pitch for the firmly sprung suspension by strictly mechanical means.
The Audi RS 4 Avant Nogaro selection rides on 265/30 series tires. Behind the gloss turned finish 20-inch wheels in 5-V-spoke design gleam red-painted brake calipers bearing RS emblems. The brake discs featuring a wave design are internally ventilated, perforated and joined to the aluminum brake disc chambers by pins. Audi installs carbon-fiber-ceramic discs at the front axle on request. The Electronic Stabilization Control (ESC) offers a sport mode and can also be entirely deactivated as required.
