Inside, the occupants will definitely notice the premium leather upholstery with contrasting piping and stitching, as well as the Alcantara headliner and the lovely beige-birch accents.

What People Are Saying Give it to me straight


In normal driving, the six-speed automatic shifts into its upper gears very early, and the transmission is reluctant to kick down unless you really boot it.
by Car and Driver (Sep, 2005)
Its claimed 7.7sec 0-62mph sprint figure suggests that it's quick, but traffic jams around Munich meant that all we can tell you with certainty is that it's a pleasantly quiet engine and a bit of an anti-climax after surging around in the turbodiesel.
by EVO (Jun, 2005)
A couple of other things worth noting about the V8 turbodiesel motor are that it's a light and compact piece of kit, and that its exhaust system features the latest-generation particulate filters to cut down on the smoke screen that some oil burners still leave in their wake during hard acceleration.
by EVO (Jun, 2005)


One of the reasons for having a diesel engine, of course, is for its fuel economy, and should you have the discipline to drive the A8 in a modest fashion, then it will give 30mpg on the Combined cycle - on the other hand, it will also do 0-62mph in 5.9sec, so chances are you won't ever manage a fuel consumption figure that looks quite so healthy, though it would still seem parsimonious compared with a V8 petrol-engined A8.
by EVO (Jun, 2005)
Several of us in the evo office have reservations about diesel engines as appropriate propulsion for proper sports cars, but this Audi oil-burner - and doubtless the V8 turbodiesels from Mercedes and BMW - demonstrates that a punchy and well-mannered turbodiesel has a place in high- performance luxury saloons.
by EVO (Jun, 2005)
At higher speeds, the W-12 advantage is even greater, with the A8L accelerating from 60 to 120 mph in 12.5 seconds and the V-8 needing 18.9 seconds.
by Car and Driver (Sep, 2005)


But for the fact that it's not keen to rev much beyond 4200rpm, you'd assume it was just your regular modern petrol V8.
by EVO (Jun, 2005)
Because although it has 322bhp and an extraordinary 479lb ft of torque - easily eclipsing the outputs of the previous 4-litre unit in the A8, along with all its rivals - it is, after all, a diesel.
by EVO (Jun, 2005)
Compared with other sedans that one must acquire, the big Audi is about as quick as the BMW 760Li but is 1.1 seconds slower in the quarter-mile than the Mercedes-Benz S600 road rocket.
by Car and Driver (Sep, 2005)


This spacious interior feels worthy of the six-figure price.
by Car and Driver (Sep, 2005)
Otherwise, the W-12's controls work well.
by Car and Driver (Sep, 2005)
Because you're so well cocooned by sound and vibration insulation, the speedo is the clearest indicator of just how rapidly you're picking up pace; the rush of the outside world seems a little at odds with the calm inside the cabin.
by EVO (Jun, 2005)


While the petrol V6 will undoubtedly serve many A8 owners well (and save them money with its ΂£47,930 starting price), the 4.2 TDI is by far the more intriguing package and considerably quicker.
by EVO (Jun, 2005)
That's 114 more ponies than are present in the V-8-powered big Audis, and they make themselves known when you put your Ferragamos to the plush carpeting.
by Car and Driver (Sep, 2005)
At the same launch as the 4.2 TDI, Audi also revealed a new petrol direct injection - or FSI in Audi-VW-speak - 3.2-litre V6 with 256bhp at 6500rpm and 243lb ft of torque at 3250rpm; this engine will be soon be dropped into sportier Audis.
