CARB found another emissions-defeating device, this time from Audi

The California Air Resources Board has discovered another emissions-cheating device on an Audi earlier this summer, reports German newspaper Bild am Sonntag. The device is different from the software found in the VW Group's diesel-powered engines, as it alters the way the cars' automatic transmission shifts. The latest device, according to Bild am Sonntag, measures how far the cars' steering wheel is being turned. If the wheel is turned less than 15 degrees, indicating that the vehicle is being tested in laboratory conditions, a program in cars with certain automatic transmissions changes the way the gearbox shifts. The change in the transmission allows the engine to produce less carbon dioxide than when driving in normal conditions. When the wheel is turned more than 15 degrees, the program automatically turns off, claims Bild am Sonntag. The paper reports that Audi took the software out of its vehicles, which was used in both diesel- and gasoline-powered vehicles in Europe and the US, earlier this May after CARB discovered the program on one of the automaker's older cars. Several engineers that were connected with the emissions-cheating device have already been suspended, reports Bild am Sonntag. As the German newspaper points out, the device, which is fitted to certain Audis with an automatic transmission, is different from the cheat devices found on the automaker's 3.0-liter TDI turbodiesel V6 engine and Volkswagen's 2.0-liter turbodiesel motor, even those were also designed to beat emissions tests. The 3.0-liter engine is found in the Audi Q7, Volkswagen Touareg, and Porsche Cayenne models. Audi didn't immediately respond to our request for a comment.

VW going turbo-only in 3 to 4 years

This really was a matter of when, rather than if. Volkswagen will apparently be the first manufacturer to phase out naturally aspirated engines in favor of turbocharging its full slate. VW is kind of responsible for ushering in this push towards small-displacement, turbocharged engines that's taken the industry by storm. When it dropped its direct-injection, 2.0-liter turbo in the 2005 GTI it demonstrated that strapping an iron long to an engine can enhance the powertrain as a whole. VW made fuel economy gains, while also giving a linear, non-laggy turbo experience that it has replicated, model-after-model, to this day.
Speaking with The Detroit News, Volkswagen's executive Vice President of Group Quality, Marc Trahan, told the paper that, "We only have one normally aspirated gas engine, and when we go to the next generation vehicle that it's in, it will be replaced. So three, four years maximum."
Really, it's hard to get teary-eyed about either of these engines going away. VW has access to smaller powerplants that could easily match the performance of the 2.5 five-cylinder and the 3.6 V6, while gobbling up less fuel and providing a better driving experience. What we are sad about is that a similar statement about the extinction of NA engines came from the Vice President of Powertrain Engineering at Ford, Joe Bakaj. We'd certainly get teary-eyed over a world without Ford's excellent 5.0-liter V8.

Volkswagen unveils sportier Passat Performance Concept ahead of Detroit debut

Ahead of its official unveiling at next week's Detroit Auto Show, Volkswagen has released some preliminary details and images of its Passat Performance Concept - a car that, as its name suggests, adds a little more spice to the automaker's midsize sedan formula. VW makes no mention of any production intent for this road-ready-looking sedan, simply stating that the Performance Concept is a way to "explore this practical four-door's sportier side."
It certainly doesn't look too sporty, the only visual upgrades being larger 19-inch wheels, dual exhaust, bi-xenon headlamps with VW's Advanced Front Lighting system, LED taillmaps and carbon-look mirror caps. Inside, there are carbon interior accents and two-tone leather upholstery. But no matter, the real upgrades for this mightier Passat are found below the sheetmetal.
Powering the Performance Concept is a 1.8-liter turbocharged four-cylinder engine, churning out 250 horsepower and sending its grunt to the ground via a six-speed automatic transmission. For reference, that's 80 more horsepower than the Passat's base 2.5-liter inline-five, but 20 horsepower less than the potent 3.6-liter VR6. As for other performance upgrades, Volkswagen has fitted the car with a lowered sport suspension and revamped electronic steering, which should indeed add a bit more dynamic feedback to the already nice-driving sedan.
