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.

MotorWeek looks back at the 1986.5 VW Scirocco 16V

It's back to the past with MotorWeek for a video dive into the 1986.5 Volkswagen Scirocco 16V, the coupe that carried the pennant for VW's performance aspirations for 15 years, from 1974 to 1989. This one, the last generation, got the hottest of all by adding a head with four valves per cylinder. The 1.8-liter DOHC engine cranked out "an amazing" 123 horsepower and 120 pound-feet of torque, and made this model the fastest VW to ever be sold in America; it went from 0 to 60 miles per hour in 8.5 seconds, faster than a Porsche 944. To compare vintage apples to modern ones, the New Scirocco with a 123-hp 1.4-liter TSI engine and a manual transmission takes 9.3 seconds. We like MotorWeek's Retro Review series not only for the cars, but for how they also remind us of what we used to find important in cars. The Scirocco here gets upvoted for its throttle response and handling, downvoted for an oddly placed oil pressure gauge and lack of battery voltage meter. We can't remember the last time a voltage meter was mentioned in a review, either its presence or lack. Check out the video above for what the definition of "US hot hatch" used to be.

Carmakers ask Trump to revisit fuel efficiency rules

Car companies operating in the US are required to meet stringent fuel efficiency standards (a fleet average of 54.5MPG) through 2025, but they're hoping to loosen things now that President Trump is in town. Leaders from Fiat Chrysler, Ford, GM, Honda, Hyundai, Nissan, Toyota and VW have sent a letter to Trump asking him to rethink the Obama administration's choice to lock in efficiency guidelines for the next several years. The car makers want to revisit the midterm review for the 2025 commitment in hopes of loosening the demands. They claim that the tougher requirements raise costs, don't match public buying habits and will supposedly put "as many a million" jobs up in the air. The Trump administration hasn't specifically responded to the letter, although Environmental Protection Agency nominee Scott Pruitt had said he would return to the Obama-era decision. The automakers' argument doesn't entirely hold up. While the EPA did estimate that the US would fall short of efficiency goals due to a shift toward SUVs and trucks, the job claims are questionable. Why would making more fuel efficient vehicles necessarily cost jobs instead of pushing companies to do better? As it is, even a successful attempt to loosen guidelines may only have a limited effect. All of the brands mentioned here are pushing for greater mainstream adoption of electric vehicles within the next few years -- they may meet the Obama administration's expectations just by shifting more drivers away from gas power.
