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 Q7 testing gives us clearer view of new look

Audi just announced its intentions to build the Q1 in 2016. By that time, the company will already have introduced the opposing bookend to that subcompact utility vehicle, the fullsize Q7. The last time we saw the next-gen Audi Q7 out testing, our spy shots were very low quality and didn't reveal much about the luxury SUV. This time around we're able to make out a few key elements about the Q7.
For starters, the unfinished headlights have a stylish, wave-like lighting element with a three-dimensional appearance, while the rear of the Q7 will definitely get a similar wraparound liftgate as the current model. Overall, this prototype looks to be about the same size as the existing Q7, so it will be interesting to see how Audi squeezes almost 800 pounds from the SUV's curb weight. The diet will surely help improve efficiency, and we also hear that Audi is considering a plug-in hybrid model in addition to the standard gas and diesel variants.
Riding on a shared platform with the next-gen Volkswagen Touareg, Porsche Cayenne and the upcoming Bentley Falcon SUV, the next Audi Q7 is expected to bow in late 2014 for the 2015 model year.

An amazing Group B rally car collection heads to auction

Kicking off in 1982, the Group B era spawned some of the most fearsome rally cars of all time. The technologically advanced pioneers of all-wheel drive and turbocharging defined a time when automakers had carte blanche to build machines with unrestricted power, without the burden of homologating a large number of road cars to qualify. The results were sometimes deadly, leading the FIA to ban the class after 1986. Now, a collection of seven Group B monsters is headed across the block in Paris as part of the Artcurial auction, held in partnership with France's famed Retromobile show. The show has been delayed to June, however. There's a 1985 Peugeot 205 Turbo 16, one of 20 Evo II models that helped the company achieve two championships in Group B's short run. This particular example was driven by world champion Timo Salonen at the 1986 Swedish Rally, where it finished seventh due to an oil filter seal failure. Bruno Saby subsequently drove it at the 1986 Tour de Corse and Peugeot entered it at the 1986 Acropolis Rally as well. It's still registered to Peugeot Talbot Sport and represents a French technological achievement, according to Artcurial, comparable to the Concorde or TGV train. Representing Italy are a pair of Lancias in the iconic Martini livery. The Lancia 037 helped Bel Paese clinch its only Group B victory in 1983, after a hard-fought rivalry with Audi. It's one of the few Group B cars that weren't AWD, achieving its success the old-fashioned way, through lightness and superb handling. A second Lancia, a 1986 Delta S4, was the culmination of the Italian firm's later Group B efforts and one of Saby's favorites. While Group B was no more in 1987, the S4 was the predecessor to the Delta Integrale that would dominate WRC from 1987 through 1992. While the collection also includes greats like a Ford RS200, Renault 5 Maxi Turbo, and MG Metro 6R4, the centerpiece is the Audi Quattro Sport S1. The ultimate Group B machine, it introduced all-wheel-drive and turbocharging to the sport. It also employed the wildest use of wings and air dams to generate downforce. Tunable up to 590 horsepower, it could rocket to 60 mph in about three seconds. The car offered for sale came straight from Ingolstadt, a 1988 model built for the Race of Champions of ex-Group B cars. The collection was amassed in the late 80s and early 90s, not long after Group B's dissolution.
