Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.

2014 Audi RS5 Cabriolet [w/video]

Brash Bruiser Loses Top, Gains Weight, Still Makes Friends
Everything we said after driving the RS5 coupe still rings true, even after Audi has gone and ripped off its metal roof, replaced it with a big cloth version, and tossed us the keys. The 2014 Audi RS5 Cabriolet is another bold, big-boned airmobile to make open-top lovers swoon. There is absolutely nothing revolutionary to speak of here versus its hardtop counterpart, frankly, but tear-assing through the southern French hills as the brilliant sun warmed us is plenty good reason to talk a lot about it anyway. And hey, it beats frigid January in Detroit, where the RS5 Convertible is shortly to receive its US introduction.
One issue that could corrupt things a bit is the convertible's added weight factor. It's one thing when an Audi TT removes its top and gains 176 pounds, or when a Porsche Cayman morphs into a Boxster and gains 66 pounds; the effect on dynamics will still be acceptable. But when it comes to a huge-roof coupe like the RS5, that gain in mass becomes 400-plus pounds in cabrio form, for a grand curb weight of 4,461 pounds. As a number attached to this size of a car that's also branded with an RS badge promising raciness, we admittedly fretted. Then we drove the Audi RS5 Cabriolet to cheer up.

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.
