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 Quattro tech shoots for the moon

Most automakers seem satisfied building vehicles to drive on the Earth's surface. But not Audi. The German automaker is quite literally shooting for the moon with the vehicle you see here. Called the Audi Lunar Quattro, it forms what promises to be an integral part of one team's campaign for the Google Lunar Xprize. That team calls itself Part-Time Scientists, and is the only German contingent of the 25 that originally entered from around the world and the 15 that are still in the race. Sponsored and technically assisted by Audi, the Lunar Quattro is a solar-powered moon rover. It packs an adjustable solar panel and a lithium-ion battery powering four individual hub motors – one in each wheel. It can only travel at a theoretical maximum of 2.2 miles per hour, but outright speed isn't the point here. It's been designed to traverse the difficult terrain of the moon's finely dusted and craggy surface. It'll need to travel at least 500 meters (1,640 feet) and will transmit high-definition video footage from the twin stereoscopic camera on its swiveling head back to Earth. The lunar rover is scheduled to be launched aboard a rocket from Earth to the moon by the end of 2017. The 240,000-mile trip will take five days and is targeted to land north of the moon's equator – close to the place where Apollo 17 (NASA's last manned lunar mission) landed back in 1972. Before that, though, it'll be presented by Audi sales chief Luca de Meo (who's since been named the head of Seat) at the Cannes Innovations Days forum. You can check it out in the gallery and extensive press release below, but first, we suggest you watch the video playlist above while preparing to check out tonight's red moon eclipse.

The group of German engineers are working within the framework of the Google Lunar XPRIZE competition to transport an unmanned rover onto Earth's natural satellite. Audi is supporting the Part-Time Scientists with its know-how in several fields of technology – from quattro drive and lightweight construction to electric mobility and piloted driving. The moon rover will be named the "Audi lunar quattro." "The concept of a privately financed mission to the moon is fascinating," says Luca de Meo, Audi Board Member for Sales and Marketing. "And innovative ideas need supporters that promote them.

Audi S1 officially shows itself as 228-hp hot hatch [w/video]

We got the first leaked pics of the new Audi S1 Sportback five-door hot hatch yesterday, and as expected, Audi has unloaded the full details today, including confirmation of its S1 three-door sibling ahead of its debut at next month's Geneva Motor Show. The two cars are essentially identical aside from their door counts, and together, they represent a new entry-level rung into Audi's S car range.
The subcompact S1 is propelled by Audi's ubiquitous 2.0 TFSI four-cylinder, tuned here to produce 228 horsepower and 279 pound-feet with a six-speed manual transmission and all-wheel drive. The potent combo accelerates the S1 to 62 miles per hour in 5.8 seconds (5.9 seconds for the Sportback) and on to a top speed of 155 mph. Fuel economy is rated at an average 33.6 miles per gallon (40.3 mpg UK) in the UK cycle. The S also gets a completely different four-link independent suspension to replace the less sophisticated torsion beam setup found in the standard A1.
Styling also gets a bump in aggressiveness that befit the S1's performance upgrades. In addition to a new body kit with a lower front air dam and 17-inch wheels, the S1 comes standard with Xenon headlights, LED taillights and two new available exterior colors ­- Vegas Yellow and Sepang Blue. The interior gets combination leather and cloth sport seats, piano black trim and a retractable 6.5-inch color infotainment display.
