There's no doubt the latest A3 isn't as well finished inside or as polished overall as the previous model, but it still rates well against the premium competition of the day, which includes the BMW 1 Series and Mercedes A-Class. The A3's comfortable, enjoyable to drive, has space for the family and a range of punchy petrol, diesel and hybrid engines. We recommend the 40 TFSIe for its electric range, low company car tax and performance. It’s one of the best plug-ins out there and a fine car in its own right.
