The V8 quattro was notoriously innovative. It was also quite complicated (read: expensive) and therefore painfully slow selling. At a time when all European imports were suffering from the global recession, the range-topping V8 busted budgets. Introduced for the 1990 model year in the U.S., the launch year was really the only marginally successful one; just shy of 3,000 were sold between 1989 and 1990. However, even light revisions in 1991 and a major engine upgrade to 4.2 liters failed to bring buyers to dealerships. Audi sold 527 1991s, 270 1992s, 170 ’93s and a scant 78 ’94s. Statistically speaking, you’re about as likely to run across a 4.2 V8 quattro on the road as you are a BMW M1.
By 1994 there was no denying that the Type 44-derived D11 chassis was quite old. Audi admitted it themselves with the big splash of their new ASF concept in 1994 – a thoroughly modern large executive again full of innovation, this time with its extensive use of aluminum. Audi brought that design to market largely unchanged in the all new D2 A8 range. And to help keep costs in check, while the V8 quattro had only been available in one configuration each model year, Audi introduced options in the A8 range. The one that got the headlines was Audi’s signature all-aluminum 4.2 V8 mated to the all-wheel drive quattro drivetrain. But if you wanted range-topping looks and didn’t need the sure-footed nature of the quattro system, you could briefly opt out.
That’s because Audi launched a FronTrak (front-wheel drive) A8 model. Instead of the larger 4.2 model, motivation was provided by destroked 3.7 liter unit. Rated at 230 horsepower and matched only to the 5-speed automatic tiptronic and weighing the best part of 4,000 lbs., it was pretty underwhelming in just about every respect. 0-60 was a leisurely 8.3 seconds, and despite the decrease in power, the 3.7 was no less thirsty than the 4.2. While it did save you about $7,500 ($56,900 v. $64,500 base price for the 4.2) it was no surprise, then, that the bulk of Audi’s deep-pocketed fanbase chose to the 4.2 quattro model, and the base 3.7 was dropped in the 2000 model year in favor of the long wheel base model. Early A8s are hard to find – Audi sold only about 6,000 over three model years before the refresh. But 3.7 have become a bit of an oddity that are almost never seen:
