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 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.

Evo drives the Audi R18 E-Tron Quattro on track

Audi invited Evo scribe Richard Meaden to the Misano circuit in Italy to drive the Audi R18 E-Tron Quattro - and not just any R18 Quattro, were such a thing possible, but the No. 2 car that took first place at Le Mans this year driven by Marcel Fassler, Andre Lotterer and Benoit Treluyer. Meaden got just four laps in the diesel hybrid racecar - a warm-up, two hot laps and a cool down lap - so this wasn't about testing the R18 E-Tron's limits. In fact, Meaden makes it clear that such a thing isn't even possible for less than a professional driver; when driving at his limits (admittedly in Audi's very expensive car being watched by dozens of Audi engineer eyeballs), the data showed he was using 60 percent of the pedal effort of the professionals. Nevertheless, Meaden does have a lot to say about how the car delivers its massive ability, and with the wide-view shot of the cockpit we also get to see how busy and how intimate an endurance driver's office is.
