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.

2016 Audi A8 L 4.0T Sport bridges the gap to S8

Want to get your hands on an Audi S8, but can't quite make the stretch? You may be interested, then, in the newest addition to the A8 family. Because it just may be the next best thing. As the moniker suggests, the 2016 Audi A8 L 4.0T Sport packs a similar 4.0-liter twin-turbo V8 to the one in the S8 (and the Bentley Continental GT for that matter). But instead of 520 horsepower, it's tuned to produce a somewhat more modest 450. That's also less than the 500 hp offered in the W12 model, but then the V8 engine is a fair bit lighter, and it produces 15 more horses than the previous 4.0T model. Along with the upgraded engine comes a sportier look, with larger air intakes at the front, more sculpted side sills, and 20-inch (or available 21-inch) alloys. It also comes standard with the Executive and Luxury packages, complimented by diamond-quilt stitching, and a headliner upholstered in Alcantara with a panoramic sunroof. Of course, it's also priced a fair bit lower than the aforementioned more powerful versions: $90,500 (plus $925 destination) is a relative bargain compared to the $114,900 commanded by the S8 and $137,900 for the A8 L W12. Audi has yet to release performance figures, but we'd expect it to drop a tenth or so off the 4.4-second 0-60 sprint achieved by the previous, 435-hp model. Those looking for more power than the S8, not less, may still hold out hope for the S8 Plus with its 605 hp to make its way to US showrooms.

Audi RS6 Avant and Mercedes-AMG E63 S drag race for Top Gear

Sometimes the kids are late for school, and you need a wagon to get them there in a hurry. In its latest drag race, Top Gear finds out which is the quicker high-performance family hauler: the Audi RS6 Avant or the Mercedes-AMG E63 S. The specs suggest this race should be quite close at the finish line. The RS6 has a 4.0-liter twin-turbo V8 with 552 horsepower, but the E63 S is a little more powerful with 577 hp from a 5.5-liter twin-turbo V8. However, the Audi has a traction advantage from the all-wheel drive system, whereas the Mercedes only spins its rear wheels. Pick your favorite, and then watch the video to see if the similar numbers translate to a photo finish in the real world. Related Video:
