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.

Audi Adaptive Cruise Control | 2017 Autoblog Technology of the Year Finalist

Not your father's cruise control, Audi's adaptive system is another step on the road to autonomous driving. That earns it a spot as one of our Technology of the Year finalists. Audi Adaptive Cruise Control can slow down or speed up your vehicle depending on the conditions. It's also capable of coming to a full stop and then resuming speed. This allows the vehicle to move with traffic without engagement from the driver using Traffic Jam Assist at speeds up to 40 miles per hour. It's not being marketed as an auto-pilot setup. Rather, this system can increase driver safety by automatically braking as the vehicle in front slows and then accelerating once the path becomes clear. The cruise control has five programmable settings to regulate distance between vehicles. Linked with the navigation system, Audi's ACC suite uses a camera and radar to respond to its environment, a key development for future systems that will need to communicate with the grid. The system can read street signs, allowing it to slow down or speed up. Additionally, when a destination is set, the vehicle will automatically brake when a turn is looming to alert the driver he or she needs to take action. It will brake through the turn and then speed up upon completing the maneuver. We especially liked this, as many navigation systems don't inform the driver when to turn or take an exit until the last possible moment. Further, when navigating curves, the Audi system will brake the vehicle and resume speed as conditions require. This Adaptive Cruise Control is a layer of artificial intelligence we can get on board with. It's like having a co-pilot to assist the driver when the inevitable fatigue or distractions appear. It engages like a normal cruise control system. Simply pull the stalk in the steering wheel mount, and there's a button to modulate the distance. We tested Audi's Adaptive Cruise Control on an A4, where it is an $1,800-option as part of the Driver Assistance Package. Working in combination with Audi's Virtual Cockpit and head-up display, ACC provides the driver a sense of awareness and greater level of information than other systems on the road. Companies like Volvo and Porsche offer similar setups, but we like the intuitiveness of the Audi program. Automakers have been saying for years that the autonomous technology is essentially here, they just need the infrastructure and regulations to catch up.

Audi readying 650-hp Sport Quattro Concept for Frankfurt

Remember Audi's perfectly lovely Quattro Concept from the 2010 Paris Motor Show? Of course you do. The latter-day Ur-Quattro is laser-etched in our brains as well - and not just because Audi was kind enough to offer our man Michael Harley a mountain drive of its seven-figure showcar. At the time, Audi hinted that the coupe might have a showroom future, but the gossip pipeline has long since gone dry, leading us to believe that the car's production hopes had soured.
That 2010 concept was powered by a 2.5-liter five-cylinder engine yielding 380 horsepower and 354 pound-feet of torque, a relatively modest but appropriate engine configuration in light of the Ur-Quattro's five-banger. Given the Quattro Concept's size and specs, it wasn't clear exactly where such a vehicle might fit into the company's lineup, though, as it already already offers the successful A5/S5/RS5 lineup.
Apparently, Audi might have a solution to that conundrum. A new report from Germany's AutoZeitung suggest that the automaker is posed to reveal a production version of the concept at the Frankfurt Motor Show in September - on the Ur-Quattro's 30th anniversary, no less. Word is that Audi is taking the Quattro Concept upmarket in a big way, with a tuned version of the twin-turbo 4.0-liter V8 from the RS7 churning up in the neighborhood of 650 horsepower. Naturally, all-wheel drive will get all that power to the ground, and new bodywork is expected as well. In addition to the powertrain switch-up, there is talk of extensive use of lightweight materials, including magnesium, carbon fiber and aluminum, with a target weight of under 2,900 pounds. Magnetic ride control suspension and carbon-ceramic brakes are also expected to find their way onto the model. Unsurprisingly, all of that extra equipment is likely to impact the car's bottom line - reports suggest its sticker price could crowd that of the mighty R8 at around $150,000.
