The Audi RS 4 Avant features a naturally aspirated V8 engine that delivers 450 PS at 8,250 rpm and maximum torque of 430 Nm between 4,000 and 6,000 rpm.

Fitted with the standard seven-speed S tronic transmission, it sprints from 0 to 62 mph in 4.7 seconds on its way to a governed top speed of 155 mph, which can be increased to 174 mph if required.
Driven more cautiously, it achieves fuel economy of up to 26.4mpg (on the combined cycle).
The RS 4 Avant features quattro permanent all-wheel drive, bolstered by the advanced crown-gear centre differential and the sports rear differential for smoother torque transfer between the front and rear axles and the left and right rear wheels.
A 40:60 split operates in normal conditions, but up to 70 per cent of power can be channeled to the front and as much as 85 per cent to the rear if required.
A torque vectoring system, which acts on all four wheels, works with the self-locking crown gear differential to further enhance power management, and the Electronic Stability Control (ESC) also offers a Sport mode or can be fully deactivated for circuit use.
The lowered chassis of the Audi RS 4 Avant, which features a five-link set-up at the front and a self-tracking trapezoidal-link rear assembly, is complemented by new speed-dependent electromechanical power steering with a direct steering ratio. This, says Audi, "helps the driver stay on course by making slight steering corrections when braking on surfaces with different levels of grip".
Polished 19-inch, ten-spoke forged aluminium wheels shod with 265/35-series tyres fill the arches which sit 20 millimetres lower than on a standard A4 Avant thanks to the RS suspension set-up. Stopping powere comes courtesy of large, internally-ventilated wave brake discs with eight-piston callipers.
For especially committed drivers carbon fibre-ceramic brake discs are also available at extra cost, as is the Dynamic Ride Control (DRC) system, which uses diagonally opposed pairs of shock absorbers linked by hydraulic lines and a central valve. During fast cornering, the system intensifies the stabilisation of the front outside wheel for increased stability and composure. Its response can be varied across three settings at the touch of a button.
When DRC is fitted it can be fine-tuned by the driver via the standard Audi drive select driving dynamics system, which offers selectable comfort, auto, dynamic and individual modes accessed by the MMI control unit.
The Dynamic Ride Control and dynamic steering options are available individually or combined as part of a £2,250 Sport Package, which includes larger 20-inch rotor design aluminium or titanium-look alloy wheels and a sports exhaust system.
The interior of the RS 4 Avant is finished in black, with the exception of the roof lining, which may be specified in Moon Silver. Chrome clasps accentuate switches and control elements. Carbon inlays are standard, with brushed matte aluminium, Aluminium Race, piano black finish or a light stainless steel mesh available as options.
The standard front sports seats with integrated headrests are power-adjustable and covered in black leather and Alcantara. Full leather packages and RS bucket seats are also available as options.
Standard equipment highlights include DVD-based satellite navigation, Bluetooth mobile phone preparation, cruise control and Audi Music Interface iPod connection.
The all-new Audi RS 4 Avant is now available to order priced at £54,925 on the road.
