Audi A8 4.2 TDI quattro: Road test report

Audi A8 4.2 TDI quattro

Nice road test report here of the new Audi A8 4.2 TDI quattro. 7 Series and S class, move out of the way. Enjoy!

If the original A8 can now be seen as an admirable first effort and the second a plausible alternative to its opponents, the third is the one whose looks, specification, technology and very demeanour no longer meekly suggest it might be as good as an S-class, but almost dare you to say it isn’t actually a damned sight better.

For a diesel-powered limo weighing substantially over two tonnes as tested, the A8’s performance is frankly preposterous. Making full use of its all-wheel drive system, that 590lb ft of torque and its army of tightly stacked gear ratios, it hits 60mph in 5.0sec flat and 100mph in 13.0sec, numbers you’d have needed a supercar to match 10 years ago. It is the fastest-accelerating diesel car we have tested, and by a huge margin.

Yet the figures themselves aren’t half as impressive as the manner in which they’re delivered. A slight grumble at idle is the only way most occupants would ever twig which fuel feeds this engine. It’s whisper quiet at a constant cruise, with just a hint of a snarl when it gets down to business. Truth is, if you never did more than 2500rpm, the A8 would still provide all the performance you’d ever really need.
