Audi recalling 70k TDI models worldwide over braking problem

Audi is issuing a recall covering some 70,000 vehicles worldwide, due to problems with their brake boosters. According to Automotive News Europe, diesel-powered examples of the A4, A5, A6, A7 and Q7 are all being called back due to this issue.
The report indicates that while the brakes in these vehicles still function, the enhancing power from the booster may fail due to a possible leaky membrane.
All of the affected vehicles are powered by the 3.0-liter TDI turbodiesel V6, and were built between March and December of 2012. It is unclear as of this writing how many of these vehicles are in the States, though remember, US customers are not privy to 3.0 TDI examples of the A4 or A5. Autoblog has reached out to Audi for specific numbers, and we'll update this space when we hear more.

Audi Quattro concept production hopes still alive, could be more radical

Remember the gestation period of the Lexus LFA, the one that, in automotive time, took so long that its origins could have been carbon dated? We feel like it's deja vu all over again, as Yogi Berra would have said, this time featuring the Audi Quattro and Audi Sport Quattro. It was 2010 when our cameras first glimpsed the Audi Quattro Concept (pictured right) at the Paris Motor Show, and we tasted its turbocharged 2.5-liter, five-cylinder powerplant not long after. Last year we met the hybrid, 700-horsepower Audi Sport Quattro concept at the Frankfurt Motor Show, but we got no closer to finding out if there'd ever be a version we could buy. A report in Autocar keeps the flame of hope burning, quoting Audi design chief Marc Lichte at the LA Auto Show saying, "We are working on Quattro, it is still alive." Lichte went on to say, however, that the next imagining is "more extreme" than those we've seen, and, "There will be surprises." Those words alone are a surprise. The last we heard about the Quattro revival was Audi boss Ulrich Hackenberg saying he wanted a more accessible homage to the original, and we don't know how "more extreme" jives with that. Seeing that Audi is serious about the idea, at least, we shouldn't have to wait long to find out. Just don't get your hopes up about its affordability yet.

Audi TT Quattro Sport Concept takes the next-gen to the extreme

There's little doubt that the new Audi TTS and its 310-horsepower, 2.0-liter, turbocharged four-cylinder will be very quick when released to the general public. As a means of reminding us that Audi can do much more with the little TT, though, the German manufacturer has presented this, the TT Quattro Sport Concept, alongside its litter of new sports cars.
Complete with a 420-horsepower, 2.0-liter, turbocharged engine - yes, it really puts out 210 horsepower per liter - the TT Quattro Sport can snap to 62 miles per hour in just 3.7 seconds. 331 pound-feet of torque is also on offer, meaning this one-off TT outguns the TTS by 110 horsepower and 51 pound-feet of torque.
An S-Tronic transmission shuffles the power about, while the car itself rides on a lowered and stiffened suspension. 20-inch alloys are featured with centrally locking, racing-style hubs. Those racy wheels are housed in wells that have had their arches stretched an additional 1.18 inches, which, along with the lowered suspension, contribute to the TT's aggressive looks.
