Audi CVT suit settlement given green light, 64,000 cars covered

Audi drivers, listen up. If you bought or leased a 2002-06 model-year A4 or A6 with a factory-installed Continuously Variable Transmission (CVT) that failed, you may be entitled to reimbursement under a recently settled class-action lawsuit with corporate parent Volkswagen.
According to Automotive News, the settlement covers about 64,000 vehicles and alleges that "manufacturing and design problems caused the transmissions to fail and left owners stuck with repair costs." While the suit also argues Audi was aware of these issues (going so far as to hide that knowledge from consumers), the settlement stops short of acknowledging any wrongdoing by the German automaker.
Audi drivers are eligible for a cash reimbursement if their CVT repairs occurred within 10 years or 100,000 miles of the date they bought or leased the vehicle before June 19, 2013. To be eligible for compensation, drivers must submit a claim form (found here) with supporting documents by November 18.

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

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.
