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 RS7 is a 189-mph terror

If you have a burning desire to take yourself and four friends to 189 miles per hour, the 2014 Audi RS7 Sportback can help you out. The luxury hatchback bowed at the 2013 Detroit Auto Show today, complete with a 560-horsepower twin-turbocharged 4.0-liter V8 engine thrashing under the hood. Getting to 62 mph takes a shave under 3.9 seconds thanks in part to the 553 pound-feet of torque on hand from just 1,750 rpm. While the base car comes with an electronically limited top speed of 155 mph, customers can request the governor be removed by purchasing the dynamic package plus, upping the V-max to 189 mph.
Ludicrous? Sure, but Audi says the RS7 can also yield up to 25 mpg on the US scale. With a cylinder-on-demand system, the V8 can deactivate up to four cylinders by closing their valves. Once the driver gets frisky with the throttle, the engine automatically kicks from four-cylinder to eight-cylinder mode in a few hundredths of a second. The engine is bolted to an eight-speed automatic transmission, which pushes power to all four wheels.

Is the Audi R8 E-Tron project back on again?

If you ask Audi about its R8 E-Tron prototype, the all-electric two-seater that was first shown at the 2009 Frankfurt Motor Show, the automaker will tell you that its development program is on hold. Yet, as we reported in January, limited production of the combustion-free coupe may be moving forward... information still officially unconfirmed by the automaker.
New images of the electrified R8 undergoing winter testing in Europe have emerged (above and in our gallery), and the car has been spotted running in Spain as well. Both sightings support reports that the E-Tron, with its 150-mile battery range and 8:09 Nürburgring time, may be back in business. Does the program have a green light, or is Audi merely trying to take some of the thunder from the BMW i8?
Whatever the case, if the R8 E-Tron does eventually make it into showrooms - and we are now led to believe it will - expect production volume to be very low. Assuming it doesn't get shelved again, of course.
