Audi A5 Coupe review - MPG, CO2 and Running Costs

Economical on paper but almost 70mpg is tough to match in the real world

The most efficient A5 is the 35 TDI diesel, which returns up to 55.4mpgand emits 133-136g/km of CO2, while the 40TFSI petrol returns figures of 42.2mpg and 150-152g/km.

Many Audi A5s will be run as company cars; Benefit in Kind percentage charge figures sit between 30 and 35 per cent depending on engine. The top-of-the-range RS5 sits in the highest 37 per cent bracket.

Insurance groups

The Audi A5 starts at group 27 for the entry-level 35 TFSI in Sport trim. The range rises to group 43 for a 40 TDI quattro in Vorsprung trim, while the 444bhp RS5 sits in group 44.

By comparison, the BMW 4 Series ranges from group 24 for the 418d SE to group 42 for the 435d xDrive Luxury and M Sport. The BMW M4 sits in groups 42 and 44 for coupe and convertible models respectively.

Depreciation

Our experts predict that the A5 will hold onto 33 to 50 per cent of its value come trade-in time after three years and 36,000 miles. Diesel-powered examples hold their value best, while the higher-powered petrol options in expensive Vorsprung trim are best avoided if residual values are a concern.
