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.

California orders VW Group to fix 15,000 3.0L diesel vehicles

The California Air Resources Board has ordered Volkswagen to come up with a plan for repairing approximately 15,000 cars sold in the state that contain illegal software that may circumvent emissions testing. In a letter sent to Volkswagen Group of America and several company brands, CARB's chief emissions officer says the company has 45 business days to submit a recall plan that will fix affected Volkswagen, Audi, and Porsche models equipped with 3.0-liter diesel engines sold in the state since 2009. "We expect full cooperation in this investigation so this issue can be addressed expeditiously and appropriately," wrote Annette Herbert, chief of emissions compliance. The violations first surfaced in a meeting last week between California regulatory officials and Audi executives. In that meeting, Audi admitted certain versions of A6, A7, A8, Q5 and Q7 models contained three previously undisclosed auxiliary emissions control devices. An auxiliary device is not necessarily the same as a defeat device that intentionally cheats on emissions testing, but Audi and other affected brands hadn't disclosed the existence of the AECDs, which is a violation of the state's health and safety code. Had they been disclosed prior to vehicle certification, there's a possibility CARB may have approved use of the devices. In a statement Wednesday, CARB did not elaborate on whether it considered the three devices mere AECDs or defeat devices. When Volkswagen submits its plan to fix the cars, CARB says it must include an assessment of how the repairs will affect fuel economy, performance, drivability, and the safety of each vehicle. The 15,000 cars affected in California are part of roughly 85,000 nationwide which contain the affected 3.0-liter engines. The US Environmental Protection Agency may soon address how it expects Volkswagen to fix the remaining cars. "EPA and CARB are working closely and continue to investigate following the admission by Volkswagen that the issues EPA identified in the November 2nd NOV (Notice of Violations) extend to all 3.0-liter diesel Volkswagen, Audi, and Porsche vehicles," an agency spokesperson said in a statement Wednesday. "EPA will take all appropriate enforcement action." The 3.0-liter developments, of course, come on top of the company's September admission that 482,000 diesels equipped with 2.0-liter engines contain defeat devices that detect emissions testing and alter the cars' performance.

Volkswagen Caddy gets the Alltrack treatment for Frankfurt

We've seen Alltrack versions of the VW Golf and Passat. The German automaker's commercial vehicles division has even done a concept version of the Multivan with a similar treatment. And now it's taking that same rugged off-road approach with the Caddy van. The new Caddy Alltrack starts off with the latest, fourth-generation city van revealed earlier this year in Geneva, and beefs it up to replace the previous Cross Caddy. That comes down principally to black trim on the wheel arches, side sills, bumpers, and underbody protection with metallic accents. It also packs unique 17-inch alloys, fog lights, chrome trim on the grille, silver roof rails, a new optional beige metallic paint (pictured), and Alltrack logos galore. The interior has similarly been worked over with unique trim. Though no mention has been made of any suspension upgrades, the Caddy Alltrack can be specified with 4Motion all-wheel drive. Prospective buyers (in markets where VW offers its commercial vehicles line) will also have to choose between passenger and panel van body-styles, and between four diesel and three gasoline engine options. They range in output from 74 to 123 horsepower and come mated to manual or dual-clutch transmissions with five, six, or seven gears. Look for the new Caddy Alltrack to highlight the Volkswagen Commercial Vehicles display at the Frankfurt Motor Show opening later this week.

The successor to the Cross Caddy is called the Caddy Alltrack. Like its predecessor, it is available both in passenger car and panel van formats. The latest version of the urban delivery van and family MPV is clearly distinct from the other Caddy models with its exclusive 17-inch alloy wheels 'Quito', new Mojave Beige metallic paintwork and optional 4MOTION all-wheel drive technology.
