Audi A5 Sportback review - MPG, CO2 and Running Costs

The 2.0-litre TDI Ultra will make up the bulk of sales, and the low emissions mean it’s easy to see why

No matter which engine you go for, the Audi A5 Sportback is an economical and cheap-to-run family car. What it loses to the BMW 4 Series in terms of dynamics and driver fun, it makes up with its slightly lower emissions and impressive fuel economy. 

The entry-level front-wheel-drive diesel emits just 106g/km of CO2 when mated to the seven-speed S tronic gearbox. The six-speed manual isn’t far behind (108g/km), while even the quattro comes in below 120g/km. It’s worth noting that the bigger wheels on S line models will have an affect on emissions and could push your car into the next company car BiK tax band. Fuel economy of 68.9mpg for the fuel-efficient Ultra is among the best in this class, too. 

Step up to the 3.0-litre TDI and that added performance will mean taking a hit on the fuel bills. However, even the thirstiest S line versions will still return 58.9mpg and emit 124g/km of CO2, not bad when you consider the huge torque on offer.

Unsurprisingly, the 2.0-litre petrol is the most expensive car (apart from the range-topping S5 and RS 5) to run, emitting 136g/km in Sport trim and 141g/km in S line spec. Fuel economy stands at 47.9mpg and 45.6mpg respectively, and there’s no economical front-wheel-drive version on offer.

Insurance groups 

Insurance for the Audi A5 Sportback starts at group 28 for an entry-level 2.0-litre TDI ultra SE, with the better-equipped S line quattro auto coming in at group 32. The 3.0-litre TDI is group 36, while an S5 is group 41. 

For comparison, the popular BMW 420d Gran Coupe in M Sport trim is group 31, though the 440i trumps the S5 by falling into group 38. A two-door Mercedes C220d Coupe in AMG Line guise sits in insurance group 32.

Depreciation 

Residual values for the A5 Sportback are strong, and follow the current trend for Audi models. An A5 Sportback TDI ultra in SE spec will retain 46 per cent of its value after three years or 36,000 miles, while an S line auto is closer to 47 per cent. The best model in the range is actually the most expensive S5, which holds on to 51 per cent of its value over the same time frame. 

The BMW 4 Series Gran Coupe offers similar numbers, ranging from 41 per cent for the 430i, to 51 per cent for the 420d M Sport.
