What is it?
The latest and biggest addition to the Audi A3 range. It adds an extra two doors to the recently-launched three-door hatchback, and is expected to take two out of three A3 sales.
Audi is quick to point out that the Sportback is not simply a five-door A3 – it has added 58mm between the front and rear wheels to create more interior space. That manifests itself as extra room for rear passengers and a larger boot. For that extra interior flexibility, Audi asks an additional £620 over the equivalent three-door.
The front axle has been moved forward by 40mm compared with the old car, creating a shorter overhang. The Sportback uses a McPherson suspension arrangement up front, with a four-link rear set-up at the rear.
Predictably weight has increased. The car tested here has gained an additional 30kg over the three-door, which has had a marginal impact on its on-paper performance and fuel economy. But you’d have to test them side by side to notice. Even with the weight increase, it is still substantially lighter than the car it replaces.
The 2.0-litre TDI engine we’re testing here will account for around 40 per cent of this model's sales. It’s a comprehensively worked-over version of the engine from the old car, but Audi has done enough to keep it among the class best. The engine will be initially offered with a 148bhp output, but a 181bhp version will arrive next spring.
