For This engine is so quick you wonder why anyone would choose the V8 petrol. Economy is impressive for such a swift car, while resale values are better than the petrol models'. The long-wheelbase version's extra rear legroom makes this a comfy four-seat limo.

Against This 4.2 TDI might have better fuel economy than the petrol V8, but the 3.0 TDI makes more financial sense and is easily quick enough for most buyers.

A superb way to travel long distances quickly and in comfort – the V8 diesel is one of the best engines of its kind, and it makes this one of our favourite A8s.

Buyer's notes

Target Price team says:

The Audi A8 is available with a wide range of powerful engines but, however you spec it, it will be expensive to buy or lease and suffer from heavy depreciation.

The pick of the range is the 3.0-litre V6 diesel with Audi's quattro four-wheel-drive system, but business users might be tempted to wait for the petrol-electric hybrid A8, which will go on sale in the UK in 2013. This will be able to run on electric power alone for a few miles, making short zero-emission journeys feasible, and helping to its low 147g/km CO2 emissions that bring low tax liabilities.

Every A8 comes with a long list of standard equipment, and Audi lets you personalise your car with a range of high-tech options, including night-vision assist, internet connectivity and all-LED headlights.

I have had my new A8 4.2TDi for about 2 months now, following a previous model A8 3.0TDi. In a number of respects the new A8 is not as good as the old…
