The Audi RS4 is making a comeback after a four-year hiatus — and like the original introduced in 2000, it will be sold in estate form only. The third incarnation of Audi’s hot load hauler has made its first public appearance at the Geneva motor show.
Right-hand-drive cars should arrive in the UK this autumn. Exact UK pricing has yet to be finalised, but insiders hint that the RS4 Avant will come in at around £55,000, pitching it into direct competition with the Mercedes-Benz C63 AMG estate, which costs from £56,765.
Audi has given three reasons for offering the RS4 in Avant form only. It says its hot estates have always traditionally outsold their saloon equivalents, the market is moving away from hot four-doors, and the S5 Sportback has sufficient power for those wanting a performance Audi four-door in the segment.
At the heart of the new RS4 Avant is the same naturally aspirated 4.2-litre V8 found in the RS5. The four-valve-per-cylinder unit kicks out 444bhp at 8250rpm. This is up by 30bhp on the previous RS4, but torque remains as before at 317lb ft between 4000 and 6000rpm.
By comparison, the C63 AMG estate’s naturally aspirated 6.2-litre V8 delivers 451bhp in standard trim, rising to 480bhp in combination with an optional performance package, together with 442lb ft of torque.
Audi has not revealed a weight for the RS4 Avant prior to Geneva, although it’s almost certain to be beyond the 1725kg of the RS5. It does, however, claim 0-62mph acceleration of 4.7sec, which is 0.2sec faster than the old second-generation model and just 0.1sec slower than the rapid RS5. Top speed is limited to 155mph in standard trim, but a performance option can raise that figure to 174mph.
Drive is channelled, as in the RS5, through a specially calibrated version of Audi’s seven-speed, dual-clutch automatic gearbox. It has a manual mode that can be controlled via steering wheel-mounted paddles or the gear selector lever. Launch control is standard.
A quattro permanent all-wheel-drive system is also standard. At the heart of this is Audi’s self-locking crown-gear centre differential, a fast-acting power split that can send up to 70 per cent of power to the front wheels and up to 85 per cent to the back. An active Sport rear differential is optional, with two ‘super-position’ stages to actively distribute power between the car’s individual rear wheels. Without it, the car’s traction control-based torque vectoring system juggles power asymmetrically across both front and rear axles.
