Audi A1 Sportback 1.6 TDI

A few weeks ago, we drove an Audi A1 Sportback with the new 138bhp 1.4 TFSI petrol engine, which is capable of shutting down two cylinders on the move. Now it’s the turn of the diesel efficiency champion.

The five-door A1 1.6 TDI weighs 25kg more than its three-door equivalent, but offers identical 74.3mpg fuel economy and 99g/km CO2 emissions. On the road, it doesn’t feel like a pared-back eco special. Press the throttle and the speed builds steadily and smoothly with little more than a hum from under the bonnet. Refinement is so good that it’s easy to forget you’re in something the size of a VW Polo.

But if it’s driving thrills you’re after, prepare to be let down. The A1 is naturally agile, due to its compact size and low weight (1,165kg), yet the steering lacks feel and there’s no real reward for driving enthusiastically. If you want something sportier, go for the 1.4 TFSI petrol. But if you must have a diesel, there’s a 141bhp 2.0 TDI joining the line-up this summer. It’ll do 0-62mph in 8.2 seconds and return 68.9mpg.

The three trim grades (SE, Sport and S line) get gradually firmer suspension and larger wheels as standard. Unless you have your heart set on the S line styling upgrades, you should stick with SE or Sport models, which strike a better balance between comfort and body control. Besides, you can always order up to 18-inch alloys from the options list. 

To fit the extra doors, Audi has made the A1 6mm higher and 6mm wider. The result is an extra 11mm of headroom and 13mm of shoulder room in the back. Boot space stays the same at 270 litres, or 920 litres with the seats folded. Climbing into the rear seats is easier, but once there, it’s still cramped for six-footers.

If style is high on your list of priorities, as it will be for most Audi buyers, don’t worry – the transition from three to five-door has been executed to perfection. The rear window is marginally more upright and the B-pillar has been moved forward by 240mm, but at a glance you’d be hard-pushed to notice any difference.

Whether you go for SE, Sport or top-spec S line trim, the Sportback looks just as sharp as the three-door.
