MotorWeek revisits Audi's iconic Quattro

The Subaru WRX, Mitsubishi Lancer Evolution and just about every other all-wheel-drive performance car owes something to the legendary Audi Quattro, a model that was far more successful on the motorsports scene than it was in the showroom. Despite its modest sales, the UrQuattro still looms large in automotive lore, and indeed, in Audi's own sense of self. Considering the brand's semi-regular flirtation with the idea of a reborn Quattro, MotorWeek must have figured it'd be a good idea to revisit the original by digging up this archival review.
While time has the ability to cover up the warts of iconic automobiles, it should be noted that Motor Week host John Davis had more than a few critiques for the all-wheel-drive, turbocharged coupe.
Davis calls the Quattro's slalom handling "a disappointment," citing the overpowered engine and slow steering, and he had some unkind words for the brakes, as well. For our part, we're kind of wowed by the amount of ship-like body motion during testing, yet that sort of bobbing was certainly par for the course back in the early '80s.

Delphi plans automated-driving journey across the United States

Delphi is attempting to become the first company to pilot an automated car across the United States. The global automotive supplier will start a cross-country journey from a location near the Golden Gate Bridge in San Francisco starting on Sunday, March 22, and cover approximately 3,500 miles on a trip to New York, where it will arrive sometime during the New York Auto Show. Along the way, Delphi engineers will gather data on how the car, an Audi SQ5, performs in a variety of road and weather conditions that the company says could only be tested in a real-world environment. "Delphi had great success testing its car in California and on the streets of Las Vegas," said Jeff Owens, the company's chief technology officer. "Now it's time to put our vehicle to the ultimate test by broadening the range of driving conditions." A formal announcement is expected tomorrow during the SXSW festival in Austin, TX. The company recently demonstrated many of its advanced-safety and automated driving technologies during CES, driving in Las Vegas. The cross-country trip will include tests on its radar, vision and advanced-drive assistance systems, certain vehicle-to-vehicle and vehicle-to-infrastructure communications, and intelligent software, which includes automated highway pilot with lane-change technology, automated urban pilot and automated parking functions. Though a driver will be behind the wheel throughout the journey, Delphi says its active safety technologies can make complex decisions, like stopping and proceeding at four-way stops, timing highway merges and calculating safe maneuvers around bicyclists. While California has certain motor-vehicle laws that help regulate autonomous vehicles, it was unclear whether Delphi needs special arrangements or permission from other states to conduct automated-vehicle testing elsewhere – or if those concerns might be negated by an active driver. Earlier this year, Audi turned heads at CES by driving an A7 from San Francisco to Las Vegas in a similar display of automated-driving technology.

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.
