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 R8 lines up as safety car for Rolex 24 at Daytona

This weekend a new era begins in American sports car racing with the Rolex 24 at Daytona to kick off the new United SportsCar Championship, the freshly inked union between the Grand Am and American Le Mans Series. There'll be a wide variety of machinery lining up on the grid at the Florida speedway, including race-ready versions of the sports cars you can drive on the road, plus Daytona Prototypes, Le Mans Prototypes and even the DeltaWing. But at the front of the pack will be the Audi R8 5.2 FSI.
That's because Ingolstadt's flagship has been named as the official safety car for this, the 52nd annual Rolex 24 at Daytona. And so the R8 becomes the first pace car pressed into service for the United SportsCar Championship, although the model also paced last year's race (pictured above) when it was under the auspices of the Grand Am series.
The car in question appears to bear little in the way of modifications over the showroom version, save for some requisite graphics and maybe some emergency lighting to make it more visible - because while you wouldn't miss an R8 slicing its way through ordinary traffic on the road, it's another story entirely in a field full of competition machinery. Audi points out that the road-going R8 shares a good 50 percent of its components with the R8 LMS competing in the race, including its 5.2-liter V10 engine that's available this year with a new seven-speed dual-clutch transmission.

Audi Q8 E-Tron could have 370-mile range

Audi technical boss Ulrich Hackenberg has a huge job ahead of him if he's going to add more electrified models his employer's portfolio. Currently, the German company's electrified offerings amount to just the Q5 Hybrid in the US and the A3 E-Tron in Europe, but British auto mag Autocar is claiming that Hackenberg wants to add a Tesla Model X-rivaling electric version of the company's long-rumored Q8 utility vehicle to the plans. That E-Tron model, said to be a high-riding crossover with coupe-like lines, is expected to be Ingolstadt's CUV flagship, positioned just above the Q7 (pictured above).
Autocar further maintains that Q8 E-Tron will borrow its front- and rear-mounted electric motors (good for around 375 horsepower) from the recently revived R8 E-Tron, and the model could be ready as soon as 2017. This sporty CUV is expected to have a much greater range than the two-door electric sports car, however. Figure on about 370 miles thanks to room for extra batteries.
The still-not-confirmed Q8 range is expected to be offered with gasoline, diesel and plug-in hybrid powertrains, and will ride on the same platform as the Q7, albeit fitted with sleeker styling. Like all of Audi's upper-end offerings, it will make extensive use of aluminum for the body and chassis to keep weight down.
