With the Audi badge on the front and lots of gadgets on board, the A1 costs a little more to insure than superminis like a Vauxhall Corsa or Ford Fiesta. The entry-level 25 TFSI engine puts the Audi A1 in insurance group 16 out of 50, while the more powerful engines are in higher insurance groups. Range-topping 40 TFSI models sit in group 31, which is high for a supermini.
