Next Audi R8 to be up to 130 pounds lighter

"Simplify and add lightness," as Lotus founder Colin Chapman said. In a world where even supercars are subject to environmental, efficiency and emissions standards, lighter vehicles are being looked on as a sort of panacea - make it lighter, and it's automatically faster, more agile, easier to brake and better on gas.
Knowing this, it comes as no shock that Audi is looking at ways to lighten up its next-generation R8, with the brand's head of technical development Ulrich Hackenberg targeting a 110- to 130-pound diet for the mid-engine rocket. This supports previous reports regarding the focus for the next R8. Motor Trend reports that aluminum and carbon fiber feature heavily in plans for the next R8, which should go a long way toward slimming down even the lightest of R8s, the 3,678-pound V10 Plus model.
There's more over at Motor Trend, including the buff book's attempts to get Hackenberg to discuss powertrain options for the next R8.

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 execs mulling turbocharged, entry-level R8

The just-launched, second-generation Audi R8 is apparently a pretty fantastic example of Vorsprung durch Technik. While it's sublime to drive, Audi might already be missing some potential sales due to the lack of an true entry-level version in the supercar's lineup. Lending further credence to an earlier rumor about just such a model, company execs are saying to expect an entry-level, turbocharged R8 to launch in the coming years. "It is inevitable that we will go to a turbocharged motor for it at some point," Audi technical development board member Dr. Ulrich Hackenberg said to Motoring. "It would be in this model cycle, to give us a fuller range." The executive certainly isn't mincing words about forced induction, but the V10's position in the lineup is also secure. "It doesn't mean we are not going to do a turbo, but naturally aspirated is here to stay as well," he said. If Dr. Hackenberg's direct assertion isn't enough, Quattro GmbH chief Heinz Peter Hollerweger further clarified to Motoring that the turbocharged engine would slot into the bottom of the R8's range. An unnamed "senior sales and marketing source" within the Audi also said that the company's turbo five-cylinder was among the currently favored choices for the application. The first rumors about the R8 getting a forced induction version arose just a few months ago. At the time, Audi's electrically turbocharged, 2.5-liter inline five-cylinder was considered an option. The model would solve a problem in markets, like China, that severely tax big displacement engines. Customers might not even need to worry about giving up too much performance either. In the Audi TT Clubsport Turbo concept, the powerplant has a total output of 600 horsepower and 479 pound-feet of torque. While 10 fewer ponies than the latest R8 V10 Plus, it would bring 66 lb-ft more twist to the supercar.
