The latest versions of these Audi A4 engines have impressive official fuel and CO2 figures, as low as 112g/km for the most frugal of the TDIs and 119g/km for 141bhp 2.0-litre TDI - another reason why its the pick of the bunch. It's real-world test consumption proved less impressive, but an overall figure of 38mpg and a touring score of 48mpg are acceptable.

The low-power TDIe records an official average of 65.7mpg - about 3mpg more than the 141bhp motor. By our calculations, you should expect a real-world 50mpg when touring with this unit. No diesel has an official combined fuel consumption figure of less than 48mpg; even the big 3.0-litre.

A touring economy of 48mpg is acceptable

All of the petrol engines officially record 40-something-mpg figures, S4 aside. Frankly if you're expecting frugal running costs with this, you're looking at the wrong type of car entirely.

If you ignore the lure of so-called premium brands and consider the A4 against the excellent Ford Mondeo, its sticker price looks distinctly poor value against the Ford in top-of-the-range Titanium X trim. And the Audi is short of several toys at this level of comparison, including sat-nav.

It looks better value compared with its German-badged rivals, but as ever you are buying the brand experience as much as the car itself. Audi is forecasting slightly above-average residuals compared with its German rivals, which is consistent with recent history.
