The second-generation Audi A1 has been spotted undergoing cold weather testing yet again, with the test mule seen here not deviating that much from an earlier sighting.

Set to ride on the MQB platform like other Volkswagen Group models (Seat Ibiza and Volkswagen Polo), the new A1 looks visibly bigger than before. It also adopts a new front fascia that appears to be inspired by the A4 and A8, including sharper-looking headlights and a wider singleframe grille.

Prominent character lines, slightly flared fenders and a wider stance also help project a more muscular appearance for the supermini. The rear doors also appear longer than the current model, suggesting more interior room to go along with the revised dimensions.

Moving towards the rear, a new tailgate design results in two-piece taillights being used on the A1, which differ from the ones used currently. A small roof spoiler and rakish rear window are some of the other elements seen here.

The new A1’s interior is still a mystery for now, although it is expected to carry the latest MMI infotainment system and other technologies. Given the advance equipment available on the latest Polo, a selection of digital displays and touchscreens will likely be offered.

Under the hood, the upcoming Audi A1 is set to receive a new 1.0 litre, three-cylinder base engine, along with new 1.5 litre turbocharged engines with up to 150 PS. Also a likelihood is a high-performance S1 variant, which will likely get the 200 PS 2.0 TSI engine from the Polo GTI.
