2011 Frankfurt Auto Show

Revealed: Audi S6, S7, and S8 before Frankfurt

Audi is going all-out next month at Frankfurt with the launch of their new more powerful and more fuel efficient high-performance S lineup.

Audi has just unveiled official photos and details of three new S models that will make their live debut at the Frankfurt Auto Show. The Audi S6, S7, and S8 are the latest in Ingolstadt's high-performance lineup and are being described by the automaker as having "power combined with appropriately low fuel consumption." Beginning with the S6 and its S6 Avant wagon variant, Audi claims to have remade both models, making them better sports cars for everyday use. And yes, they're more powerful than before.

Both are powered by a new version of the 4.0-liter twin-turbo V8 TFSI with 420hp and 405lb-ft of torque. The S6 can go from 0 to 62mph in 4.8 seconds and the S6 Avant can do it in 4.9 seconds. Top speed is electronically limited to both at 155mph. A seven-speed S tronic transmission provides power to the Quattro permanent all-wheel drive system. The previous models were powered by a 5.2-liter V10, but Audi claims this new powerplant offers even sportier performance while reducing fuel consumption by as much as 25 percent.

In addition to the engine, a number of new technologies have been added such as start-stop systems as well as the new "cylinder on demand" cylinder management system. Both are constructed from roughly 20 percent aluminum, making them especially lightweight for their performance and size category. The interior is adorned with S6 badges, a leather sport steering wheel with colored stitching and aluminum shift paddles, and many other upscale features you'd expect in an Audi interior. The beautiful new S7, like its sedan and wagon siblings, utilizes the same engine and seven-speed S tron transmission as the S6 and S6 Avant.

This 4.0-liter twin turbo V8 allows the four-door coupe to accelerate from 0 to 62mph in 4.9 seconds and an electronically limited top speed of 155mph. And like the S6, the S7 is all about maximizing power and fuel efficiency in one sleek package. With the use of the same cylinder on demand technology, the S7 averages 24.25 mpg. Additionally, the car's efficiency is enhanced by its lightweight body, which is composed of a hybrid aluminum construction and weighs roughly 15 percent less than a comparable all-steel body. Although the S7 is based entirely on the S6, its body is quite different.

With its long hood and wheelbase, short overhangs, and low roof line, the S7 is absolutely gorgeous. The typical S and V8 T badges are also present throughout. And finally, there's the new S8. Set to hit the market next spring, the new S8 is the epitome of power and luxury. Power comes from the new 4.0 TFSI with 520hp and 479lb-ft of torque and is mated to an eight-speed Tiptronic transmission. It goes from 0 to 62mph in just 4.2 seconds and top speed is, once again, capped off at 155mph. Fuel consumption is also quite reasonable, considering the S8's size and power output.

Audi claims it'll average about 23mpg, which is a 23 percent decrease from the previous version. Other technologies include the aforementioned cylinder on demand technology and the Active Noise Cancellation system that suppresses intrusive noise and vibration. The interior, like that of any Audi, is of the finest craftsmanship and puts many other luxury brands to shame with its attention to details, big and small. Pricing for the new models hasn't yet been released. The new S lineup models will be unveiled in the flesh in just a couple of weeks at Frankfurt.
