MPG, running costs & CO2 Rating

3.5 out of 5

From launch, Audi has relied on sophisticated petrol engine technology to keep the A1's fuel economy and emissions figures competitive, although it's possible that a mild-hybrid system could be introduced later. Running costs are generally similar to those for the Volkswagen Polo, although Audi customers face rather higher maintenance charges than those who drive a VW.

Audi A1 MPG & CO2

You can expect good fuel consumption figures on all versions of the A1, except perhaps the range-topping 40 TFSI. The entry-level 94bhp turbocharged three-cylinder 1.0-litre 25 TFSI petrol engine claims up to 49.6mpg with CO2 emissions of 128g/km with 15-inch alloy wheels fitted. That’s partly thanks to the tall ratios in its standard five-speed manual gearbox, although the seven-speed S tronic automatic returns a decent figure, too, at 46.3mpg. For company car drivers, that means a Benefit-in-Kind (BiK) tax rating similar to its rivals.

A more powerful 113bhp 30 TFSI is a tuned version of the same engine, and actually manages ever-so-slightly better fuel economy at 50.4mpg on the entry-level model - partly thanks to a sixth gear in the gearbox. Above that, the 35 TFSI is fitted with a 1.5-litre petrol with cylinder-deactivation technology, a system that effectively reduces the size of the engine when full power isn't required. It’s only available with Audi’s S tronic automatic gearbox, and offers up to 44.8mpg despite plenty of punch.

The A1 40 TFSI is the thirstiest at 40.4mpg. It has an uncharacteristically large 2.0-litre turbo that's related to the engine found in models like the Volkswagen Golf GTI - it produces 197bhp. There's a strong possibility of mild-hybrid engines joining the A1 range, but diesel engines are very unlikely.


You’ll find the expected top-selling 30 TFSI in groups 19-21, while the less powerful 25 TFSI occupies group 16.

As you might expect, the group ratings increase as you ascend the engine range, with the 35 TFSI rated insurance group 25-26, and the sporty 40 TFSI carrying a group 31 classification. Remember, though, that personal circumstances can have more effect on insurance costs than group ratings, so always obtain a quote before making a decision to buy a new car.


Audi's long-life service schedule is recommended if you drive over 10,000 miles a year. It uses oil quality and wear sensors to determine when a workshop visit is due. Alternatively, you can opt for a fixed one-year interval if you cover a lower annual mileage. There are fixed-price service plans to cover both regimes and make it easier to budget for routine maintenance.


Every Audi comes with a three-year/60,000-mile warranty, which is exactly the same as you get with a Volkswagen Polo. By comparison, the MINI is covered for the same period but with no mileage limit. At the end of your warranty, you can purchase an extension to make sure you're still covered, although the extended warranty does feature some exclusion.
