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.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

2018 Audi A5 gets a manual and S5 gets 369 lb-ft of torque

Update: A previous version of this post incorrectly stated that the A5 was the only Audi model to offer a manual transmission with the 252-horsepower inline-four. Audi will offer the same combination on the A4 in the near future. The text has been updated to reflect this. When Audi revealed the new A5 and S5 coupes, we knew the elegant lines of the European model would come to the United States. But the big question was, would the drivetrains, and in particular, the manual transmission, come along? The answer is yes. The 2018 A5, with its 252-horsepower, 273 lb-ft of torque turbocharged four-cylinder, will be offered in America with both a seven-speed dual-clutch transmission, and a classic six-speed manual. These combinations will take an A5 to 60 mph in 5.6 or 5.7 seconds, respectively. The A4 sedan will also offer the manual with the same engine soon, in case you need an extra pair of doors. The four-cylinder model is also the only A5 model with a manual, since the turbocharged V6 S5 only comes with an 8-speed automatic. To make up for a lack of shifting involvement, drivers can take advantage of the S5's readily available torque. Like the Euro-spec model, our S5 will come with 369 lb-ft of twist, and it peaks at a stunningly low 1,350 rpm. That torque, combined with the engine's 354 horsepower, launches the S5 to 60 mph in 4.4 seconds. Every type of A5 or S5 also funnels its power through a Quattro all-wheel-drive system with torque vectoring. A5 owners can also personalize how their cars ride and handle, with either a sport suspension with different sway bars, shocks, and springs, or with the comfort adaptive damping suspension. The latter uses constantly adjusting electronic shocks for improved ride. The S5 has an available sports adaptive suspension that works similarly, as well as a dynamic steering option that can change steering ratios. Capping things off is an extensive list of gadgets and safety features, some standard, such as the LED interior lighting and panoramic sunroof, and others optional, such as Audi's Virtual Cockpit LCD instrument cluster and lane keeping assist. A new feature for the A5 line is the MMI touch system, which allows drivers to write in characters with their fingers. Something Audi hasn't revealed about the A5 and S5 is the pricing and availability, but those details should come soon.
