Audi A4 review - as refined and composed as ever, but is the new A4 fun? - MPG and running costs
No matter the body style, this is the best A4 yet
All engines deliver both fuel consumption improvements and CO2 reduction benefits over their predecessors – and, since diesel cleanliness has been in the headlines a lot this year, it should be noted that all A4s, both petrol and diesel, meet stringent Euro 6 emissions regulations. On paper, at least…
Most efficient of all, if that’s your priority, is the 2.0 TDI ultra in 148bhp form. Ultra has become the word Audi attaches to its most economical cars, the A4 ultra has the lower suspension from the Sport model, low rolling resistance tyres on 17-inch wheels and active aero flaps to improve how aerodynamic it is. The result is combined economy of 74.3mpg and CO2 of 99g/km for the manual version. The dual-clutch transmission changes those figures to 72.4mpg and 101g/km, while the higher-power 187bhp TDI Ultra matches that economy figure and adds 1g/km to the CO2.

Economy of the petrol models varies between 55.4mpg for the 2.0 TFSI with 187bhp and the S Tronic ‘box, to 47.9mpg for the all-wheel drive, higher-output 2.0 TFSI. Upgrade to the full-fat 3.0 TDI and economy doesn’t drop significantly – combined economy sits at 55.4mpg.
