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.

Entry-level Audi R8 to go turbo after all?

Would you be shocked if we told you that the better version of the Audi R8 offered a V8 engine rather than a V10? There was something inherently lovable about the company's 4.2-liter V8. Maybe it was the noise or the high-revving nature or some combination of the two, but the R8's original engine is a darn hoot. Sadly, the V8's days appear numbered in the brand's flagship model, according to a new report from Car, which claims Audi will ditch the beloved, off-angle 4.2-liter for a 2.9-liter, twin-turbocharged V6. The rumor cites sources in Ingolstadt who claim the new engine will develop 450 horsepower, up 20 ponies on the current entry level engine. We'd expect a commensurate increase in fuel economy too, befitting of a smaller, force-induced engine. Still, this is counter to what we've heard before. But, if the report proves true, the R8 will join the ranks of turbocharged supercars like the Ferrari 488 GTB and California. It's unclear when such a switch would be made, but according to Car, we can place the blame squarely on China. The country has been combating large-displacement engines since 2008, attaching massive taxes on vehicles with anything larger than a 3.0-liter engine. It's China's position, Car reports, that led to the death of another beloved, naturally aspirated V8, Mercedes-AMG's 6.2-liter model. First the venerable M156 and now Audi's 4.2-liter V8? Just stop this silliness China. Related Video:

Audi R8 E-Tron back on production map thanks to new battery tech?

Contrary to our October 2012 report, it appears Audi's R8 E-Tron program is back on track, if a report from Australia is to be believed. Drive is reporting that the German brand has changed its mind and won't be sacking the program, despite previously stated concerns about the quality and price of batteries for the R8-based EV.
We last saw the R8 E-Tron prototype in the snows of northern Europe, although footage of the car has been non-existent since that wintry test. This new report claims that a small number of R8 E-Trons will see production, which gels with what we heard back in 2012 and supposed earlier this year. Apparently, some new sort of lithium-ion battery technology has allowed for a drastic increase in range, with rumors of the original 130 miles going up to around 250. According to Drive, this makes the project feasible again.
"Our engineers and technicians are further developing the car and its electric drive system. The range has grown significantly, allowing the potential for a small-scale production," an unnamed, but high-ranking Audi employee told the Aussies.
