VW reaches out to diesel consumers with new website

Volkswagen is starting to get details out to the public about its diesel emissions evasions in the US, and the automaker now has a dedicated website for consumers. The first thing that visitors see is an apology video from Volkswagen Group of America CEO Michael Horn. The site also details all of the VW TDI's currently known to be affected here, including the 2009-2015 Jetta, 2009-2014 Jetta SportWagen, 2010-2015 Golf, 2015 Golf SportWagen, 2012-2015 Beetle and Beetle convertible, and 2012-2015 Passat. Although, the Audi A3 should be on there, too. The company repeatedly reassures owners that these vehicles are safe to drive and promises it's developing a fix as quickly as possible to make them emissions compliant. On the site's FAQ, VW also clarifies that there's still a stop-sale on all of these models with the 2.0-liter TDI, including certified pre-owned ones. That could change soon because the automaker believes that the 2016 model year examples are legal, but the Environmental Protection Agency needs to sign off before they could go to dealers. Until the diesels can be sold, there also won't be any TDI advertising by VW. "We are working at full speed on a technical solution that we will present to partners, to our customers and to the public as swiftly as possible," Herbert Diess, CEO of Volkswagen passenger car division, says in a statement. He also offers an improved accounting of the number of vehicles affected. VW had previously said that there were 11 million with the emissions evading software worldwide. According to Diess, around five million of these came from the VW brand. Audi has said there about 2.1 million of its models affected globally with between 13,000 and 14,000 in America. DR. HERBERT DIESS, CEO OF THE VOLKSWAGEN PASSENGER CARS BRAND, EXPLAINS: "WE ARE WORKING AT FULL SPEED ON A SOLUTION." Wolfsburg, September 25, 2015 – In the press release dated September 22, 2015, the Volkswagen Group announced that Volkswagen Group vehicles worldwide are affected by the current issues regarding emissions. The internal evaluation revealed that approximately five million Volkswagen Passenger Cars brand vehicles are affected worldwide. Certain models and model years of these vehicles (such as the sixth generation Volkswagen Golf, the seventh generation Volkswagen Passat and the first generation Volkswagen Tiguan) are equipped exclusively with type EA 189 diesel engines.

Audi celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?
