Audi's competitor for the Toyota Prius

Audi has launched a new, more efficient version of its A3, which is capable of over 62mpg.

Audi has improved the engine, transmission and aerodynamics of the 1.9 TDI model so that it can attain an average of 62.7mpg and carbon dioxide emissions of 119g/km, putting it in VED tax band B.

The car's diesel engine has been modified, using friction-minimising components and redeveloped ancillary components, such as the alternator, while the gearbox's ratios are designed more for economy than for performance.

Additionally, an indicator in the cabin tells the driver the most efficient time to change gear, and the car's tyres have reduced rolling resistance.

Aerodynamics have also been improved to reduce the car's drag.

The modifications mean the A3 1.9 TDI can do the 0-62mph sprint in 11.4sec and reach a top speed of 120mph - that's down 0.1sec and 2mph on the standard 1.9 TDI, but fuel economy is better by 13.1mpg and 32g/km of carbon dioxide.
