Audi TT Ultra - Best diesels
Don't let the idea of a diesel coupe put you off - the Audi TT Ultra gives supermini running costs in a much sleeker, more glamorous form

For a lot of people, the idea of a diesel coupe is just a step too far but for many others its proving to be a winning formula. British buyers are responsible for more sales of the Audi TT than any other country in Europe - and most of the ones we buy are diesel-powered.
The new, third-generation TT is the best model yet and in diesel guise it's a brilliant choice. Our pick of the range is the Ultra model, which uses a 2.0-litre diesel producing 182bhp. It'll go from 0-62mph in just over seven seconds - yet can return 67.3mpg if driven carefully, with CO2 emissions of 110g/km.
The TT in any guise is a great coupe - while it's not the most fun to drive, it's hard to argue with its fine handling and secure stance on the road. It's also got a fantastic interior - the 'Virtual Cockpit' is a work of genius and its full of clever touches like the air-conditioning controls positioned in the centre of the vents. Build quality is also stellar. If you value mpg and fun this is the sports car for you.
