Feds allege widespread Volkswagen cheating on clean-air rules

Volkswagen intentionally installed software in nearly a half-million diesel vehicles that helped the cars evade substandard results on emissions tests, the federal government charged Friday. The Environmental Protection Agency issued a notice of violation to the German automaker, saying the company's software broke the law by violating two provisions in the Clean Air Act. Circumventing the standards meant affected cars emitted as much as 40 times the allowable level of certain pollutants. Both the EPA and California Air Resources Board have launched investigations. In its notice of violations, the EPA said Volkswagen officials admitted to installing and concealing what they call a "defeat device," which was designed to detect when the cars were undergoing official emissions tests – and only turn on emissions controls during that time. "Our goal now is to ensure that the affected cars are brought into compliance, to dig more deeply into the extent and implications of Volkswagen's efforts to cheat on clean air rules, and to take appropriate further action," said Richard Corey, executive officer of CARB. The allegations cover approximately 482,000 vehicles sold in the United States over the past seven years. Cars involved include diesel versions of the Jetta, Beetle, Audi A3 and Golf manufactured between the 2009 and 2015 model years. Passats manufactured for the 2014 and 2015 model years are also included. Federal officials note there is no safety danger to motorists, but the cars will be recalled for repairs. If true, Volkswagen faces a fine that could run in the hundreds of millions of dollars -- likely higher than the $300 million charge the EPA levied last November at Hyundai and Kia for exaggerating the fuel-economy in several models. The charges also put a tremendous dent into the company's plans to increase sales of its "Clean Diesel" vehicles in North America. In a written statement, Volkswagen Group of America acknowledged it had received the notices from the EPA and CARB. "VW is cooperating with the investigation; we are unable to comment further at this time," it said. Federal officials said the defeat-device software was uncovered during an independent analysis by researchers at West Virginia University, who in working with the International Council on Clean Transportation, a non-governmental organization, raised questions about emissions levels.

This semi-autonomous stroller from VW is a great idea

We're still on the fence about the prospect of autonomous vehicles. On the one hand, they promise to make commuting a breeze and collisions a thing of the past. On the other, they stand to take us away from the steering wheel, and that's something we can't abide. But an autonomous stroller, now that's the kind of idea we can get behind. Shame such a thing doesn't exist... right? That's what we assumed until we saw this spot from Volkswagen. The German automaker's Dutch office posted on Facebook, asking the public for suggestions on how the company might improve other products, aside from automobiles. The most popular response was a baby stroller with automatic braking. So they went ahead and built one. The resulting prototype – and we're sorry to report that it's just a prototype for the time being – doesn't just have automatic braking. It can even follow the parent (or nanny or whomever) around under its own power and with its own steering. It's got the adaptive cruise control sensor from a Golf and is programmed to keep a fixed distance from the guardian in front. Or so the video suggests, at any rate. There's a good chance that there's some manner of trickery going on here, probably in the form of a hidden engineer off-screen with a remote control, and hopefully without an actual baby on board. Whether it's real or not, the invention in the commercial is sure to pique the interest of the parents among us, and maybe get those without kids thinking about taking that big step... stroller autonomously in tow.

VW Jetta TDI dyno shows HP loss trying to recreate cheat mode

Volkswagen is working on a fix for diesel-engined vehicles that are out of compliance with emissions regulations in the US and other countries. We're told that engineers will be presenting a solution internally sometime this month, but that doesn't mean we'll actually see it in the wild this month. One big question we have about the coming fix is, will it affect the car's performance? That question relates to another we have about the engine as it is: How much performance would the 2.0-liter diesel lose right now if it were turned down to pass US emissions? The Fast Lane Car tried to sketch some answers by going to a shop in Denver, Colorado to run a 2011 Jetta TDI with a six-speed DSG transmission on an all-wheel-drive dyno. The thinking was that if you ran all four wheels the car would think it was on the road, whereas if you ran only two the car might think it's being tested. We'll get straight to the numbers: the stock sedan is quoted at 140 horsepower and 236 pound-feet of torque. When run with all four wheels turning it produced an uncorrected 114 hp and 214 lb-ft at the wheels. When run with just two wheels in motion the Jetta got 113 hp and 188 lb-ft at the wheels. Reading the graph, we're told that power differences between the two runs were as much as 15 hp and 32 lb-ft. You'll need to take some salt with these numbers, though, because the dyno and test protocol in the video are nothing like those used by the EPA. The shop attempts to trick the Jetta into 'emissions testing mode' by using the front wheels only for the two-wheel-drive run, but we have a feeling the software code at issue is far more sophisticated than that, since the ICCT, UVA, the EPA, and CARB investigated the situation for more than a year and couldn't figure out. Also, the technician adjusts for being a mile above sea level with a correction factor of 1.2 applied to horsepower and torque, which inflates the disparity in the final power differences over the two runs.
