Most frugal of the A7 pair is the 50 TDI, which achieves a combined economy figure of 48.7mpg and CO2 of 150g/km. This is pretty much par for the class – Audi lists its closest rivals as the CLS 350d, BMW 630d Gran Turismo and 640d Gran Coupe.
The two BMWs also achieve mpg figures in the high 40s, and the latest straight-six Mercedes CLS 350d (also with standard all-wheel drive) has a provisional combined figure of an identical 48.7mpg to the Audi, which suggests an identical CO2 figure, too. It’s worth noting that the 6-series models are on their way out and an 8-series is due, so expect BMW to fight back with those cars.

The 55 TFSI is less fuel-efficient outright than the diesel, but Audi’s decision to fit quattro Ultra part-time all-wheel drive seems to have paid off, its 39.8mpg combined figure coming out ahead of the BMW 640i Gran Turismo and 640i Gran Coupe, which manage numbers in the mid-30s. The Mercedes-Benz does likewise, the latest in-line-six CLS 450 achieving 36.2mpg combined.
For other running costs it’s too early to say how A7 Sportback ownership might transpire, but as with other cars in its class, standard alloy wheel sizes of 19 and 20 inches mean tyres will not be cheap when replacement time rolls around. The Audi’s relatively frugal engines and resulting low CO2 figures do mean VED and BIK tax rates are a little lower than its predecessor, though.
