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.

Audi, Toyota land on MIT's list of 50 Most Disruptive Companies

MIT Technology Review, a magazine all about innovation, has announced its list of the 50 most disruptive companies in 2013, and both Audi and Toyota made the cut. While the term "most disruptive" may carry a negative connotation in most uses (especially in the classroom), the acknowledgement in this case is an accolade, signifying that the company is at the forefront of its industry. In a nutshell, a disruptive company is a business whose innovations force other businesses to alter their strategic direction.
Audi made the list for "pushing autonomous cars closer to fruition with a laser-scanning road detector that fits in a vehicle's front grille," and Toyota for "expanding its dominance of the hybrid-car market with its new plug-in version of the Prius."

Audi A3 E-Tron plug-in hybrid set to whiz into Geneva

The Audi A3 E-tron, which we drove in prototype form last year, is headed to the 2013 Geneva Motor Show next month. The plug-in hybrid will feature a total of 204 horsepower and 258 pound-feet of torque from the combination of a turbocharged 1.4-liter engine and a 75-kW electric motor. That motor itself is positioned between the internal combustion engine and the machine's six-speed dual-clutch transmission. The setup is good enough to scoot the A3 E-tron to 62 miles per hour in 7.6 seconds and crank out a top speed of 138 mph. Perhaps more impressively, the hatch can whir its way to 80 mph on all-electric power with an EV range of 31 miles.
Audi claims the A3 E-tron gives the world a "realistic glimpse into the future of mobility," so it's a bit unclear if the model will see production. We're encouraged by the specificity of Audi's press release (which is full of stats) and the fact that they don't label this vehicle a concept. You can check out the full press release below and judge for yourself.
