VW says it has sold over 100,000 TDI diesels in America this year

Volkswagen Group of America has lit oil-burning fireworks to celebrate the sales of more than 100,000 TDI Clean Diesel vehicles in the US between its VW and Audi brands this year. According to VW, that means it is responsible for more than 75 percent of diesel-engined cars and SUVs sold here - perhaps not surprising when the two brands offer a total of 12 diesel models.
What might be surprising is that the number of diesels isn't far off the estimated sales of 90,000 battery electric vehicles and PHEVs, with 15,000 of those accounted for by the Tesla Model S, another 12,000 or so being the Toyota Prius PHEV.
VW's keen to play up the ease of making diesel part of your life, stressing that it doesn't need any change to the refueling infrastructure and that "this is a technology delivering real answers to society's concerns about fuel consumption and greenhouse gas emissions without compromises."

Audi S1 nearly ready to rocket euros out of your pocket

Audi was out testing its upcoming S1 on the streets of Germany when our trusty spy photographers snapped the new, all-wheel-drive hot hatch that's set to succeed the limited-edition A1 Quattro.
Unlike the A1 Quattro, the S1 should sport a much less aggressive look overall. As shown in the spy shots, its wheel wells lack the meaty flairs of its predecessor while its rear wing is much more subdued. The wheels are more in line with what we expect from Audi's S models and its higher ride height is more conducive to common things like steep driveways and speed bumps that the 333-unit A1 Quattro might not encounter.
According to our spies, the S1 should hit the European market with anywhere from 220 to 250 horsepower, making it considerably more potent than competitors like the Ford Fiesta ST or Polo GTI from its parent company, Volkswagen (although it'll likely arrive at a considerably higher price than either of those pocket rockets). On the high end, that's roughly equal to the 252 ponies generated by the 2.0-liter, turbocharged four in the A1 Quattro

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.
