From the Audi website;
The 2002 S4, equipped with a biturbo, 250 hp engine with performance-boosting triple-intake manifold and sporty six-speed manual or five-speed Tiptronic® transmission, delivers without hesitation.
Mention performance to most automakers and you're likely to hear about speed, speed and more speed: How fast to 60 mph, how fast a quarter mile, top speed and the like. At Audi, we measure performance differently. Our goal is performance that's both responsive and responsible. We measure effectiveness with efficiency. In other words, a better engine is not always a bigger one.
By incorporating five-valve technology in all of our offerings, Audi is able to maximize each engine's potential. Adding aluminum and other lighter weight materials to a car means a smaller engine can match a larger displacement engine. Adding a turbocharger (or two) can also up the performance ante. And that's all good news for the person responsible for fueling the car and good news as well for those who have to breathe the air.
