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.

Jaguar F-Pace vs. Porsche Macan | Performance luxury crossover comparison

TRANSCRIPT: The luxury performance crossover. 10 years ago, the list of examples was only a few vehicles deep but today it seems like every luxury car company makes at least one of these. This specific example is a 2018 Jaguar F-Pace S and it happens to be Autoblog 's newest long-term test vehicle. And here's the thing: It's really great to drive. Welcome to the Jaguar F-Pace S. Under the hood we have a supercharged 3.0-liter V6 that makes 380 horsepower and 332 pound feet of torque, which pulls the F-Pace from 0 to 60 in just 5.1 seconds. That's a pretty sizable upgrade from the base model's 247 horsepower and 269 pound-feet of torque. The engine is paired to an eight speed automatic transmission that responds pretty quickly to the paddles when in sport mode. There are three driving modes to choose from: You have dynamic, normal and eco. Even though the F-Pace name sounds like the F-Type, aside from the powertrain, they really aren't related. It's named that because it's based on the rear-wheel-drive Jag XF, just like the E-Pace is on the XE and the J-Pace will end up being based off of the XJ. Even though the F-Pace is all-wheel drive compared to the rear-wheel XF, it is a rear-bias system, which means it belongs exactly where we are right now, on twisty, turny back roads. This is a Jaguar, which means it sounds good but it looks even better. In my opinion, this is the best looking SUV on the market today. The Caesium Blue is a new color in the U.S. for this model year and we opted to get the black package, which includes black side vents, a black grill and roof rails. This is a $70,000 luxury crossover and the materials, they're okay. The plastics, I don't know, they kind of feel cheap even with the luxury interior upgrade package. The 10-inch touch screen is pretty big, in a good way. And while the surround sound isn't the best that I've heard, it's perfectly serviceable, especially since all I want to hear is this engine. For $70,000, this is what you get: A beautiful SUV that performs incredibly on the road. But what if you want more? This Macan costs over $96,000, which is almost $30,000 more than the F-Pace S. If you wanted to, you could buy a base Cayenne and a base F-Pace for that kind of money. But with that price comes more power, thanks to this Macan Turbo's performance pack. 60 more horsepower and 90 more pound-feet of torque than the F-Pace S bringing the total to 440 horsepower and 442 pound-feet of torque.

Automakers not currently promoting EVs are probably doomed

Okay, let's be honest. The sky isn't falling – gas prices are. In fact, some experts say that prices at the pump will remain depressed for the next decade. Consumers have flocked to SUVs and CUVs, reversing the upward trend in US fuel economy seen over the last several years. A sudden push into electric vehicles seems ridiculous when gas guzzlers are selling so well. Make hay while the sun shines, right? A quick glance at some facts and figures provides evidence that the automakers currently doubling down on internal combustion probably have some rocky years ahead of them. Fiat Chrysler Automobiles is a prime example of a volume manufacturer devoted to incremental gains for existing powertrains. Though FCA will kill off some of its more fuel-efficient models, part of its business plan involves replacing four- and five-speed transmissions with eight- and nine-speed units, yielding a fuel efficiency boost in the vicinity of ten percent over the next few years. Recent developments by battery startups have led some to suggest that efficiency and capacity could increase by over 100 percent in the same time. Research and development budgets paint a grim picture for old guard companies like Fiat Chrysler: In 2014, FCA spent about $1,026 per car sold on R&D, compared with about $24,783 per car sold for Tesla. To be fair, FCA can't be expected to match Tesla's efforts when its entry-level cars list for little more than half that much. But even more so than R&D, the area in which newcomers like Tesla have the industry licked is infrastructure. We often forget that our vehicles are mostly useless metal boxes without access to the network of fueling stations that keep them rolling. While EVs can always be plugged in at home, their proliferation depends on a similar network of charging stations that can allow for prolonged travel. Tesla already has 597 of its 480-volt Superchargers installed worldwide, and that figure will continue to rise. Porsche has also proposed a new 800-volt "Turbo Charging Station" to support the production version of its Mission E concept, and perhaps other VW Auto Group vehicles. As EVs grow in popularity, investment in these proprietary networks will pay off — who would buy a Chevy if the gas stations served only Ford owners? If anyone missed the importance of infrastructure, it's Toyota.
