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.

Elon Musk: Teslas will already know where we’re going

In the future, cars will drive us. And probably not surprisingly, they'll often know where to go without us even needing to tell them. That's the theme of a short back-and-forth conversation on Twitter recently between Tesla founder and CEO Elon Musk and a user who tagged him in a comment suggesting that "it would be cool" to be able to tell a car where to go. Responding to user James Harvey, Musk replied, "It won't even need to ask you most of the time." Later, after Harvey asked how the car would know where he wants to go, another user suggested that the car would know what time you go to work. "Yeah, don't exactly need to be Sherlock Holmes," Musk tweeted. It won't even need to ask you most of the time — Elon Musk (@elonmusk) October 21, 2017 Yeah, don't exactly need to be Sherlock Holmes. — Elon Musk (@elonmusk) October 21, 2017 That the ability to know where we're going will be part of our future driving experience shouldn't be surprising. After all, the smartphones we carry around already possess the ability to predict what we want — think Google's cleverness in tailoring search results or providing traffic information just before your commute, Facebook's highly customized News Feed content or even auto-fill technology, which can predict the words you're typing. And plenty of automakers have been touting their own work in developing in-car artificial intelligence systems. Like Audi's Elaine concept, which will be able to learn, think and even empathize with drivers. Or Mitsubishi's e-Evolution concept, which can not only assist your driving, but also assess your skills and teach you how to improve them. Tesla's vehicles, of course, are being outfitted with all the latest autonomous driver-assist technology, with the automaker eager to one day reach full Level 5 self-driving capability. According to Inc., Teslas will be able to listen and respond to directional commands, and they'll even have access to your calendar to comb for information about where you need to go. Tesla has also said it's developing an update to its Autopilot hardware and remains on track to achieve full Level 5 autonomous driving by the end of this year, which strikes a lot of people as wildly unrealistic. At any rate, the promise of cars knowing what time we're sneaking out to get donuts or picking up the kids is interesting, coming from the man who has warned that AI presents "a fundamental risk to the existence of human civilization."Related Video:

Hackenberg says next Audi A4 set for Frankfurt debut

The current Audi A4 is among the oldest vehicles in the brand's lineup. Having debuted back in 2008, it's long overdue for an update, and according to our friends at Indian Autos Blog, that'll happen in roughly six months. IAB spoke to Audi research and design chief Ulrich Hackenberg, who indicated that the fifth-generation A4 will be shown at the 2015 Frankfurt Motor Show in September. The new sedan will be unveiled in "a pre-presentation" before the auto show itself, Hackenberg told IAB, adding that "you'll be happy to see it." Information beyond that, though, remains sparse. Based on our previous spy photos, we expect the new A4 to ride on the Volkswagen Group's modular MLB Evo platform that's been stretched to accommodate a larger wheelbase. The styling, meanwhile, will be more evolutionary, inspired in part by the new TT. Expect more on the next-generation A4 as September approaches. Related Video:
