I have keenness for certain numerals and combinations thereof, such as 8, 45, 430, 550, 750, and 760. No, these arent my lucky lottery numbers picked by a Gypsy fortuneteller, theyre model designators for several premium automotive models. Aficionados of full-size sedans ought to immediately spot the pattern: Audi A8, (or Jaguar XJ8), Infiniti Q45, Lexus LS 430, Mercedes S550, BMW 750i and 760Li. Whether one embraces the big sedan or laments it, theres little argument that these numbers represent some of the finest automobiles in the full-size sedan segment. This weeks road test shines the spotlight on the number "8," as in A8.
The aluminum-bodied A8 has been Audis flagship sedan since its introduction in the 1997 model year. Adding an "L" to the "A8" designation

The 204-inch long A8 L is almost identical in size to BMWs 750Li, which is perhaps its most direct competitor. Both of these vehicles are benchmark setters within the full-size, premium sedan category, but like top performing CEOs, each exhibits its own leadership style while remaining true to similar, success-building strategies.
Core strategies begin with exterior styling. Where the Bimmer is cut and chiseled, the Audi is smooth and sculpted, projecting more of a sophisticated but conservative boardroom

Audi is renowned for well-crafted cabins, and the A8 is its shining star. The interior architecture in my tester included a stunning center console finished in

Once familiarization renders confusion obsolete, drivers can easily select one of four height-adjustable variable damping suspension settings, part of Audis adaptive air suspension system. This setup arrives as standard A8 equipment; an optional performance-oriented version is also available, but in my view is unnecessary. The standard air-ride

Two engines are available in the A8 and A8 L: a potent 335-horsepower V8 and a powerhouse, 450-horsepower W12. My tester held the V8, which was capable of smoothly powering the extra-spacious A8 L from static to 60 mph in only 6.2 seconds. Thats nothing short of impressive for a sedan tipping the scales at 4,389 lbs - Audi claims an even more startling time of 4.9 seconds when the W12 is doing the pushing. Without doubt, Audis 4.2-liter V8 is one of the sweetest engines

My test unit was fitted with optional 19-inch wheels shod in 255/40R rubber. Off-the-line the sticky rubber gripped the pavement at all four corners and sling-shot the A8 L quattro out of the hole with amazing thrust while virtually eliminating wasteful wheel spin on wet or dry tarmac. Almost immediately the A8s 6-speed autobox, featuring a "sport" mode, discreetly replaced first gear with second and so on. Speed builds deceptively fast in the A8 while its high-revving V8 emits an intoxicating muted growl.
