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 reveals all-new R8 ahead of Geneva debut

This year's Geneva Motor Show is shaping up to be an absolutely orgy of supercars, but though there will be many that will surely outperform it, few have been as hotly anticipated as the arrival of the all-new, second-generation Audi R8. And here it is. Based around an all-new Audi Space Frame chassis, the new R8 is constructed of a higher proportion of aluminum and carbon fiber than its predecessor. The result is a frame that weighs 15 percent less at just 441 pounds – yet is 40 percent more torsionally rigid - tipping the scales at 3,205 lbs in top spec. Into the middle of that frame Audi has installed a revised version of its 5.2-liter V10, eschewing turbochargers but incorporating new technologies. While other powertrain options are expected to follow, Ingolstadt has gone straight for the top of the range at launch: the 'base' V10 model kicks out 540 horsepower and 398 pound-feet of torque to reach 62 miles per hour in 3.5 seconds and a top speed of 201 mph. The upgraded V10 Plus, however, turns those figures up to 610 hp and 413 lb-ft to reach 62 in just 3.2 seconds, 124 in under ten and a 205-mph top speed. All the while, Audi has also equipped the new ten-cylinder engine with both direct and indirect injection, stop/start and cylinder deactivation systems to cut fuel consumption by 10 percent. It also boasts dry-sump lubrication and a variable exhaust system. Power is transmitted to the road through a seven-speed dual-clutch transmission, a mechanical diff and a revised Quattro all-wheel drive system that can send 100 percent of available torque to either the front or rear axle. Aluminum wishbones suspend it all on 19-inch wheels (or optional 20s), with available variable steering and carbon ceramic brakes (optional on the V10 and standard on the V10 Plus). Underbody aerodynamics generate more downforce and a more slippery form, aided by a deployable rear spoiler (or a fixed carbon wing on the Plus model). All those tantalizing greasy bits are cloaked in fresh aluminum sheet-metal, riding on a track that's 1.6 inches wider: the whole shebang stretches 14.5 feet long, 6.4 feet wide and 4.1 feet high, riding on an 8.7-foot wheelbase. Among the myriad new technologies developed for the new R8 are the full LED headlights with optional laser high beams (where they're legal, at least, which currently doesn't include these United States).

Porsche would have entered F1 if Audi had blocked its Le Mans program

Go back a few years and you may have heard rumors of Porsche heading into Formula One. That never came to pass - or at least, it hasn't yet - but that doesn't mean that it wasn't close to happening. That's how committed to returning to top-level motorsport competition Porsche has become recently.
Autosport reports that just as Porsche was merging fully into the Volkswagen Group, Zuffenhausen was weighing its options for a factory racing program. Le Mans was its favorite, which makes sense, as it remains far and away the most successful constructor in the history of the famous endurance race. But the strategists at Porsche were worried that its new corporate overlords at Volkswagen wouldn't support two LMP1 programs and would favor Audi, which has positively dominated the modern era of endurance racing, coming second only to Porsche in the number of Le Mans victories it has scored to date.
Porsche's Plan B was reportedly to head into Formula One, although it isn't clear if the German automaker was intent on starting its own team, buying an existing one or merely providing engines to other teams. Porsche fielded its own cars in F1 in the late 1950s and early 60s, and returned as an engine supplier with TAG to power McLaren in the 1980s, powering Niki Lauda and Alain Prost to the World Championship in 1984 and 1985.
