Next Audi Q7 to debut with electric turbocharger?

For years, the concept of an electric turbocharger was essentially a joke sold on eBay to boost power in your slammed Civic, but in the last five years it has moved from an idea on a piece of paper to a feasible reality. Audi has already toyed with a showcase of the cutting-edge tech in road cars with the RS5 TDI concept. Now, reports suggest an electric turbo may make it to the streets as soon as next year in the next-gen Q7 (spy shot pictured above).
"I can confirm we are working on the development of the e-boost definitely," said Ulrich Weiss, Audi's diesel engine boss, to Australia-based Drive. He didn't give an exact timeframe but hinted at sometime next year, possibly in the Q7. He also suggested the chance of an RS-branded diesel model in the vein of the RS5 TDI concept on the horizon, as well.
This tech isn't entirely new for the folks in Ingolstadt. Audi's R18 endurance racer already uses such a system to capture waste heat from the engine, converting it to electric power to further power the hybrid car. The RS5 TDI concept employs a similar idea with a 3.0-liter, twin-turbocharged V6 with an electric supercharger to make up for the turbo lag. It's able to pump out 385 horsepower and 553 pound-feet of torque and allegedly sprint to 62 miles per hour in four seconds.

VW stripped of Green Car Of The Year awards for Jetta, A3 diesels

In the wake of the ongoing VW diesel scandal, Green Car Journal has announced it will rescind the two Green Car Of The Year awards that the Volkswagen Group won with diesel vehicles that have been since been proven to not meet the stated emissions levels. The two vehicles are the 2009 VW Jetta TDI, which won in 2008, and the 2010 Audi A3 TDI, which won in 2010. Green Car Journal (GCJ) did not say if it would retroactively name any replacement winners. This is the first time in the history of the Green Car Of The Year Awards that the honor has been taken away from the winner. In a statement announcing the change, GCJ publisher Ron Cogan wrote that, "this award rescission should not cast a negative light on advanced diesel technology in general. Many diesel models from a variety of auto manufacturers meet EPA and CARB emissions standards, bringing with them higher fuel efficiency, decreased petroleum use, and lower carbon emissions – all important environmental goals." VW AND AUDI RETURNING GREEN CAR OF THE YEAR® AWARDS, VEHICLES DEEMED INELIGIBLE SAN LUIS OBISPO, Calif., Sept. 30, 2015 – Green Car Journal is rescinding the Green Car of the Year® awards previously honoring the 2009 VW Jetta TDI and 2010 Audi A3 TDI, the first time this has occurred in the award program's decade-long history. Audi of America President Scott Keogh has informed Green Car Journal that Audi will return its 2010 Green Car of the Year® award in the wake of Volkswagen Group's admission that it deliberately deceived government authorities about emissions from the Audi A3 TDI. Volkswagen of America has also informed Green Car Journal it will return its 2009 Green Car of the Year® award for the VW Jetta TDI. "Rescinding the Green Car of the Year® awards for the VW Jetta TDI and Audi A3 TDI is unfortunate but appropriate," said Ron Cogan, editor and publisher of the Green Car Journal and CarsOfChange.com. "These models were selected as Green Car of the Year® above others for compelling reasons, including high fuel efficiency, reduced carbon emissions, a fun-to-drive nature, and the ability to meet 50 state emissions requirements with advanced diesel technology." However, VW Group has now admitted that its software programming intentionally caused in-lab emissions testing to read significantly lower nitrogen oxide emissions than these vehicles actually produced on the road.

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.
