Audi A3 Clubsport Quattro concept bringing its 525 horses to W?rthersee

It's almost late May, and you know what that means: the last of the snow has melted, the Stanley Cup playoffs are in full swing, the flowers are blooming, and the performance-car faithful are descending on Wörthersee in Austria for the annual GTI-Treffen.
Not only is the Wörthersee Tour (as the automaker calls it) a chance for enthusiasts to show off their rides, it's also a prime opportunity for the Volkswagen Group to show some of its most dedicated customers what it can do. Past meets have given us such notables as the Audi A1 Clubsport Quattro, Volkswagen GTI W12-650 and Skoda Fabia RS 2000 Roadster, to name just a few. And now Audi has emerged as the first VW Group brand to reveal what it has in store.
It's called the A3 Clubsport Quattro, and seems to offer a pretty clear indication of what we should expect of the next RS3. The concept is based on the S3 sedan, but swaps out its 2.0-liter turbo four for a retuned version of Audi's sweet 2.5-liter turbocharged inline-five, retuned to produce a massive 525 horsepower and 442 pound-feet of torque.

Next Audi Q7 to debut with electric turbocharger?

For years, the concept of an electric turbocharger was essentially a joke sold on eBay to boost power in your slammed Civic, but in the last five years it has moved from an idea on a piece of paper to a feasible reality. Audi has already toyed with a showcase of the cutting-edge tech in road cars with the RS5 TDI concept. Now, reports suggest an electric turbo may make it to the streets as soon as next year in the next-gen Q7 (spy shot pictured above).
"I can confirm we are working on the development of the e-boost definitely," said Ulrich Weiss, Audi's diesel engine boss, to Australia-based Drive. He didn't give an exact timeframe but hinted at sometime next year, possibly in the Q7. He also suggested the chance of an RS-branded diesel model in the vein of the RS5 TDI concept on the horizon, as well.
This tech isn't entirely new for the folks in Ingolstadt. Audi's R18 endurance racer already uses such a system to capture waste heat from the engine, converting it to electric power to further power the hybrid car. The RS5 TDI concept employs a similar idea with a 3.0-liter, twin-turbocharged V6 with an electric supercharger to make up for the turbo lag. It's able to pump out 385 horsepower and 553 pound-feet of torque and allegedly sprint to 62 miles per hour in four seconds.

Audi prices 2014 A8L TDI from $82,500*

During the Los Angeles Auto Show last November, Audi told us that it would be bringing four new diesel-powered models to the United States this year. The first to arrive is the 2014 A8L TDI you see here, and we've now learned that the big oil-sipper will be priced from $82,500, (*excluding $895 for destination).
The whole new range of diesel models will be powered by Audi's 3.0-liter TDI V6, good for 240 horsepower and 406 pound-feet of torque in this application. Of course, Quattro all-wheel drive is standard, and even in the big A8, the diesel grunt will be enough to propel the long-wheelbase flagship to 60 miles per hour in 6.4 seconds (almost a full second slower than the A8 3.0T we reviewed last fall). That said, the A8 TDI should still be a pretty engaging steer, and considering the fact that this thing will reportedly return fuel economy figures of up to 36 miles per gallon on the highway (24 in the city), a slightly slower launch time is well worth it. (The A8 3.0T tops out at 28 mpg highway.)
Elsewhere in the segment, Mercedes-Benz offers a diesel version of its S-Class flagship, retailing for $93,000 and good for fuel economy figures of 21/31 mpg city/highway. By comparison, the A8 TDI seems like a steal, and we'll be interested to see where the forthcoming BMW 7 Series diesel falls into the class of huge oil-burning barges.
