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 Prologue Avant puts new styling focus on wagons

As much as we loved the Audi Prologue Concept that debuted late last year at the LA Auto Show – and, suffice it to say, we liked the first Prologue a lot – this new Prologue Avant from the German automaker may just rock our socks that much further off our feet. We have very little by way of actual, concrete details on what's under the angular wagon-shaped skin of the Prologue Avant, but we'd be perfectly content if it kept the previous two-door's 4.0-liter twin-turbo V8 in place underhood, augmented as it was when it was again shown at CES last month with a hybrid-assist system that put total system horsepower at 677, along with a meaty 701 pound-feet of torque. With all that power routed to all four wheels through an eight-speed automatic transmission, the 0-60 time of just 3.5 seconds strikes us as plenty quick. The powertrain details hardly seem the point of this new concept from Audi, in any case. Clearly, the big deal is the new bodywork, which builds upon the beautiful foundation of the original Prologue coupe with an elongated wagon shell and three additional doors (two rear doors and a rear hatch). The attractive body sits low to the ground on exaggerated 22-inch wheels, according to Auto Express. We note high-tech lighting elements front and rear and a modified front fascia with a bit more brightwork than the previous version. Assuming there's a bit of future reality baked into the Prologue Avant – which we believe is likely, considering that the coupe we salivated over in LA was said to point the way forward for the brand – it's safe to say we're in eager anticipation of the next several years at Audi. Have a good look at the images that have so far been released, and feel free to let us know what you think. We're sure Audi is interested in hearing your opinions, too.

Is Audi readying hardcore final edition R8?

The days may be numbered on the current Audi R8, but if our latest round of spy photos is any indication, Audi's first supercar is going to go out with a bang. This camo'd tester was spotted parked somewhere in Europe, and if doesn't at least belie a faster R8, it certainly indicates that a more aerodynamically intense model is coming.
The tall rear wing is the most obvious aerodynamic change. It's joined out back by a none-too-subtle diffuser and the cannon-like exhausts of the R8 V10 Plus, while the front and side of this particular R8 are home to new side sills and winglets on the lower front fascia.
We'll be keeping our ears to the ground for any more on what looks to be another variation of first-generation Audi supercar. Until then, let us know what you think this car may foreshadow. A new halo model? A gentleman racer? Have your say below.
