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.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models. Scroll down for a press release highlighting the automaker's future fuel-saving initiatives.

Le Mans champion Allan McNish retires from LMP1 racing

Having won the 24 Hours of Le Mans three times, the American Le Mans Series title another three times and, most recently, the FIA World Endurance Championship, Allan McNish doesn't have much left to prove. Which is why he's retiring, ending this stage of his 33-year driving career on a high note.
In a statement just released by McNish himself and his team at Audi, the Scotsman said "I've had a fantastically successful time with Audi and feel it's the right time to step back from Le Mans sports-prototype racing and to look at other opportunities."
Just what those other opportunities might be is another matter. He's raced in DTM, Formula One and the International Formula 3000 series, where he won two races in 1990. McNish, 44, is also part of the BBC Radio's F1 commentary team, serves as president of the Scottish Motor Racing Club and is often called upon by the FIA to act as a grand prix race steward. Audi says he'll continue to be part of the team, just not in the driver's seat. Given his success in endurance racing, he's surely got a wide variety of opportunities to pursue, and we're looking forward to seeing where he lands.
