Audi A5 Sportback hatchback - MPG, running costs & CO2

The Audi A5 Sportback is offered with the usual crop of fuel-sipping diesels, and even the 2.0-litre petrol engine is pretty efficient

4.5 out of 5

It costs north of £30,000, but the Audi A5 Sportback should be relatively cheap to run. The 2.0-litre diesel engine is expected to be the most popular choice: as well as offering plenty of performance, it’s sufficiently economical to please high-mileage drivers.

Audi A5 Sportback MPG & CO2

The entry-level 35 TFSI engine returns up to 44.8mpg and emits 144g/km of CO2. Going for larger wheels will take emissions up, though, and it’s best to think twice before choosing Audi’s quattro four-wheel-drive system, as it can reduce fuel economy.

The 40 TFSI model returns the same fuel economy figures as the 35 TFSI, despite being more powerful. It emits 143g/km of CO2. The most powerful 45 TFSI car emits 187g/km of CO2 and returns 34.4mpg according to official figures, so despite being fast, it's not the best value for money.

The diesel versions are best for economy - the 35 TDI emits 127g/km of CO2 and returns 57.6mpg, while the 40 TDI emits 137g/km of CO2 and returns 54.3mpg.

Every version of the Audi A5 Sportback is subject to a flat road-tax rate of £150 a year. Be careful when it comes to the options list, though: if your A5 Sportback ends up costing £40,000 or more, it’ll be liable for a further tax in years two to six of ownership.

Insurance group

The 40 TDI diesel in Sport trim sits in insurance group 27, and the lesser 35 TDI is in group 26. Petrol models all sit in insurance group 33, whether you go for the 40 TFSI Sport or the 45 TFSI Vorsprung, and anything in between.

Servicing

Audi’s servicing packages should make budgeting for maintenance easy, and are reasonably priced. If you prefer not to choose this option, expect a minor check-up to come in at around £170, while a major one should cost roughly £330.

Be aware that the diesel engines use a liquid called AdBlue to reduce harmful exhaust emissions. While low- and average-mileage users should see this topped up during the A5 Sportback’s annual services, drivers who cover longer distances may need to top the AdBlue tank up themselves – and you can specify a larger AdBlue tank to avoid having to do this too regularly. See our article on AdBlue for more information.

Warranty

The three-year/60,000-mile warranty that Audi offers with all its cars is reasonable, but no more than that. Mercedes and BMW place no mileage cap on their three-year warranties, while Toyota, Hyundai and Kia all offer longer policies.
