As the range-topper alongside the petrol V8, the eight-cylinder turbodiesel comes with additional features including the quattro sports differential and 19-inch wheels as standard. Quicker sections of the route allowed us to exploit the sports diff somewhat, although the knowledge that you’re steering a car weighing in excess of 2.5 tonne is never too far off so one does tend to be a little more cautious. And this model has some balls; it may be big-boned, but it will cover the 0-100km/h dash in a dizzying 5.5 seconds, Audi says...
SPORTS DIESEL: The 4.2 TDI has serious sporting pretensions, which it backs up with Audi's sports differential for when you really want to have some fun.
The cabin has generous burr walnut inlays, a Bose audio system, electric front seats with heating and memory, four-zone Climatronic and, for extra privacy, an electric rear shade.
CLASSY CABIN: Befitting a car of this standard, the A8's cabin contains most everything that opens and shuts. It's nice and quiet, too.
