More practical four-door Sportback model will join the new RS5 coupé next year
Called the RS5 Sportback, it’s a four-door version of the recently introduced RS5 coupé and so shares its 2.9-litre unit, co-developed with Porsche, that produces 443lb ft. It drives all four wheels via an eight-speed dual-clutch automatic gearbox.
The standard RS5, with its lighter two-door body, can accelerate from 0-62mph in 3.9sec. Expect the heavier Sportback to add a small margin to that figure, placing it closer to the four-door BMW M3, which hits the mark in 4.3sec.
Although this recently spotted development car is running S5 Sportback bodywork, its wider track, made clear by the fitment of wheel arch extensions, gives away its true identity as an RS5 Sportback test car.
New additions for the RS5 Sportback will include beefier 19in alloys, larger-bore exhaust tailpipes and slightly more aggressively styled bumpers. Inside, the car’s dashboard will be identical to the RS5 coupé’s, which gets Audi’s still-impressive Virtual Cockpit digital instrument display as standard, as well as Alcantara and leather trim.
Audi has refrained from commenting on the RS5 Sportback’s arrival, but a debut for the model at the Geneva motor show in March 2018 seems likely. When it goes on sale, it’ll be slightly more expensive than the standard RS5, which is currently priced from £62,900.
