EPA discovers defeat device in more VW TDI engines

In a sternly worded letter, the United States Environmental Protection Agency has issued a new set of allegations against Volkswagen claiming that so-called emissions defeat software has been found in the company's 3.0-liter TDI V6 diesel engines. This is a completely different engine than the 2.0 TDI that has already been identified as an emissions cheater. In addition to VW, the EPA has included Audi and Porsche in this notification, as the non-compliant engine has been used in vehicles from all three manufacturers from model years 2014 through 2016. The EPA claims that cars equipped with the 3.0 TDI engine know when they are being tested for emissions, and their on-board computers switch into a mode designed to pass the stringent requirements in the United States for diesel exhaust. Vehicles sold in the United States with this engine include the 2014 VW Touareg, 2015 Porsche Cayenne, and 2016 Audi A6, A7, A8L and Q5. The EPA says there are 10,000 vehicles currently on the road with this second defeat device, along with an unknown number of 2016 models either on dealer lots or in the driveways of consumers. According to the EPA, VW's 3.0-liter TDI, like the 2.0 TDI that was found to circumvent US regulations, has code in its computer specifically written to intentionally put the vehicle's engine into a mode that allows it to meet exhaust requirements. When the vehicle is unhooked from testing equipment, it will go back into a mode that emits nine-times higher nitrogen oxide emissions than is allowable under US law. "VW has once again failed its obligation to comply with the law that protects clean air for all Americans," said Cynthia Giles, Assistant Administrator for the Office for EPA's Enforcement and Compliance Assurance. "All companies should be playing by the same rules. EPA, with our state, and federal partners, will continue to investigate these serious matters, to secure the benefits of the Clean Air Act, ensure a level playing field for responsible businesses, and to ensure consumers get the environmental performance they expect." Richard Corey, Executive Officer of the California Air Resources Board, said in a statement, "Today we are requiring VW Group to address these issues. This is a very serious public health matter. ARB and EPA will continue to conduct a rigorous investigation that includes testing more vehicles until all of the facts are out in the open." This story will be updated as new information becomes available.

LTE technology puts Audi in the driver's seat

The recently-launched Audi A3 Sportback was first-to-market with Long Term Evolution (LTE), or 4G, and LTE integration for connectivity on the move is an idea swirling all through the automotive world. Automakers see the faster speeds and faster responses of LTE compared to 3G as making it possible to one day have streaming video, cloud gaming, more intensive apps and even a virtual office with videoconferencing in your car. It will also enable more progress in machine-to-machine (M2M) adoption, giving cars a real-time ability to speak to one another and to infrastructure.
A video by Audi Deutschland looks at what might be possible not only for the average driver in an LTE-equipped car, but how a professional chauffeur might make the most of a car that can help him get his VIP passengers from carport to red carpet safely and on time. You can watch it below.

Audi RS3 and Volkswagen Golf R face off in Evo test

Typically when an automotive publication pits two rivals against each other, they come from different companies. After all, why would one automaker – even one parent company – develop two distinct models to compete against each other? Well, the Volkswagen Group isn't like most. It pits Porsches against Lamborghinis, Audis against Bentleys, Seats against Skodas... all under the same roof. In the high-powered hot hatch market, it offers both the VW Golf R and the Audi RS3. The question is, which is the better drive? Evo put them both on track for a quick bout of sibling rivalry to find out. On paper it would seem like an unfair fight. Sure, both are based on the same platform and channel their power to the tarmac through all four wheels. But the Audi's five-cylinder engine packs considerably more muscle than the Golf's four: 362 horsepower and 343 pound-feet of torque trump 296 hp and 280 lb-ft. There's just no way around that – at least until the Golf R 400 comes along. The Audi, as you might have guessed, also costs substantially more than the Volkswagen. But that's not Evo's concern here. This is a cost-no-object, bare-knuckle throw-down. Watch the ten-minute video above to find out if the cheaper, less powerful Golf R can keep pace with its more upscale and brawnier brother.
