A limited run of just 250 right-hand-drive five-door Audi RS3s are to be built following customer demand.
At the same price as the three-door, the distinctive Sportback will use the same turbocharged five-cylinder TFSI engine, which pushes out 336bhp, 332lb.ft, 212g/km of CO2 and a 0-62mph sprint of 4.6 seconds.
Seven speeds are on tap through a twin-clutch DSG gearbox, which in turn drives all four wheels with a constantly-variable torque split according to conditions. The minimum power that is sent to the rear wheels is around 15%. At 1,575kg the RS3 Sportback boasts a power to weight ratio of 213bhp per tonne, which is enough to see it limited to a 155mph top speed. Attributes like a vermicular graphite engine block and carbon-fibre reinforced polymer front wings keep weight lower than it would otherwise be.
Prices will start from £39,930 on the road, but with an extensive options and customisation list available most RS3 Sportbacks are likely to cost more.
