VW orders external probe into diesel emission scandal

There are well over 480,000 Volkswagen-made, diesel-powered vehicles currently traveling roads in the United States that do not meet the Environmental Protection Agency's emissions requirements. This, as you can probably imagine, is a very big deal, and has led VW CEO Professor Doctor Martin Winterkorn to release an official statement on the matter. "I personally am deeply sorry that we have broken the trust of our customers and the public," he said. It's important to note that these vehicles run software with a so-called "defeat device" that kicks in when the on-board computer senses that it is being tested for emissions. When the car is operating normally – in other words, when its exhaust isn't being sniffed – the cars do not meet US emissions standards. According to the EPA and the California Air Resources Board, affected cars emit as much as 40 times the allowable level of certain pollutants. "We will cooperate fully with the responsible agencies, with transparency and urgency, to clearly, openly, and completely establish all of the facts of this case," according to Winterkorn, who added, "Volkswagen has ordered an external investigation of this matter." It's not yet known who will carry out this investigation. At present, there are still a number of 2015 Volkswagen models on dealer lots that do not meet emissions requirements. VW has issued a stop sale on vehicles equipped with the 2.0-liter TDI diesel engine. What's more, the German automaker has been barred from selling 2016 model-year vehicles that use this engine, according to The Detroit News. Last year, diesel vehicles made up about 22 percent of all VW sales, which means these restrictions will have a big impact on the brand's sales performance until a remedy is found and the vehicles are approved for sale. Interestingly, the EPA has started a campaign of sorts to test vehicles from other automakers that sell diesel-powered vehicles in the United States to make sure they comply with emissions requirements under all operating circumstances. The EPA says it "will be reviewing [its] compliance protocols and introducing ways in which [it] can effectively test not only for emissions performance but also for the potential presence of defeat devices," according to a statement provided to The Detroit News.

Audi readying 650-hp Sport Quattro Concept for Frankfurt

Remember Audi's perfectly lovely Quattro Concept from the 2010 Paris Motor Show? Of course you do. The latter-day Ur-Quattro is laser-etched in our brains as well - and not just because Audi was kind enough to offer our man Michael Harley a mountain drive of its seven-figure showcar. At the time, Audi hinted that the coupe might have a showroom future, but the gossip pipeline has long since gone dry, leading us to believe that the car's production hopes had soured.
That 2010 concept was powered by a 2.5-liter five-cylinder engine yielding 380 horsepower and 354 pound-feet of torque, a relatively modest but appropriate engine configuration in light of the Ur-Quattro's five-banger. Given the Quattro Concept's size and specs, it wasn't clear exactly where such a vehicle might fit into the company's lineup, though, as it already already offers the successful A5/S5/RS5 lineup.
Apparently, Audi might have a solution to that conundrum. A new report from Germany's AutoZeitung suggest that the automaker is posed to reveal a production version of the concept at the Frankfurt Motor Show in September - on the Ur-Quattro's 30th anniversary, no less. Word is that Audi is taking the Quattro Concept upmarket in a big way, with a tuned version of the twin-turbo 4.0-liter V8 from the RS7 churning up in the neighborhood of 650 horsepower. Naturally, all-wheel drive will get all that power to the ground, and new bodywork is expected as well. In addition to the powertrain switch-up, there is talk of extensive use of lightweight materials, including magnesium, carbon fiber and aluminum, with a target weight of under 2,900 pounds. Magnetic ride control suspension and carbon-ceramic brakes are also expected to find their way onto the model. Unsurprisingly, all of that extra equipment is likely to impact the car's bottom line - reports suggest its sticker price could crowd that of the mighty R8 at around $150,000.

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.
