Volkswagen is working on a fix to bring their “defeat device” equipped cars back into EPA compliance. The SCR upgrade option is very costly and another possibility is a software fix. The latter option would likely come in the form of an ECM calibration that would work similar to “test mode” at all times, possibly robbing power and fuel economy.

The crew over at TFLCar attempted to emulate this test mode on a dyno but fell short of collecting reliable results.

While I applaud the idea of finding an affected car and trying to generate real-world test results, the tests and analysis in the video do not correlate to an actual EPA test.

GM-Emissions-Lab

While working on a story about some very old cars, I stumbled upon something relevant to the latest big story in the automotive world.

I ran into a Model T collector who’s also a powertrain engineer for Ford. Seizing the opportunity, I asked him if he could tell me what he was working on (sometimes they say no). He said that he was responsible for developing computerized engine controls. Because of that expertise, I started to ask him some questions about the software program that Volkswagen apparently used to cheat on the EPA’s diesel emissions testing.

What he was willing to say and what he wouldn’t say intrigued me. (Read More…)

2016-Chevrolet-Colorado-Duramax-TurboDiesel-059

The diesel versions of the Chevrolet Colorado/GMC Canyon will be the first to undergo increased scrutiny from the Environmental Protection Agency after the recent Volkswagen scandal turned emissions reporting on its head.

According to Automotive News, a spokesman for GM said the testing could slightly delay the truck’s fourth-quarter release.

“The EPA and CARB told us they are going to do on-road testing,” Chevrolet Trucks assistant chief engineer Scott Yackley told Automotive News.

"Vehicles are piled on top of each other in rows as they wait to be pulverized and shredded for recycling at Rifkin Scrap Iron and Metal Co. on North Niagara in Saginaw , Mich. on Friday, July 31, 2009.  Far more drivers signed up for the "cash for clunkers" program than anyone thought, overwhelming showrooms, blowing through the initial $1 billion set aside by Congress and leaving dealers panicked over when or if the government would make good on the hefty rebates."

Justin Hyde at Yahoo Autos has fine, fine reporting that U.S. taxpayers paid more than $20 million in incentives for Volkswagen diesel models under the “Cash for Clunkers” program.

According to the report, 4,599 VW Jetta and Jetta Sportwagen diesel cars qualified for the maximum $4,500 incentive under the program. Those cars were equipped with a 2-liter turbocharged diesel engine that the Environmental Protection Agency said used an illegal defeat device to cheat emissions.

The Yahoo report follows a report by the L.A. Times that shows that more than $51 million was paid to Volkswagen by the U.S. for now-bogus “green” claims. (Read More…)

BMW 650i Grand Coupe

This week, Daimler, BMW, Jaguar Land Rover and Fiat Chrysler Automobiles issued statements on how their diesel cars don’t cheat like someone else you may’ve heard of.

“The BMW Group does not manipulate or rig any emissions tests,” BMW said in a statement Thursday. “We observe the legal requirements in each country and fulfill all local testing requirements.”

BMW’s admission is notable because the automakers’ X3 diesel model was targeted by the independent commission that discovered that Volkswagen’s cars illegally polluted.

VW-sola

A recent press release on the completion and success of a three-year program to test biofuels in Volkswagen Jetta and Passat TDI models may hint that two external companies had knowledge of the high levels of NOx produced by the “Clean Diesel” vehicles.

The two California-based companies — Solazyme and Amyris — were given the Volkswagen vehicles to test their fuels. VW announced that the program was a success a few months ago, stating CO2 emissions were reduced when using the biofuels. However, the companies only would have known their fuels produced less emissions if the biofuel companies tested the emissions output using diesel fuel and compared it with their own products.

EPA headquarters

Officials from the Environmental Protection Agency said this week that they’ll change regulations to hopefully catch carmakers who cheat on emissions tests in the future.

EPA Administrator Gina McCarthy told reporters at a Wall Street Journal forum Tuesday that the agency would be “upping its game” to stop automakers like Volkswagen from creating two dramatically different emissions cycles for its cars — a cleaner “testing mode” and a dirtier real-world mode. The agency said it would also crack down on automakers who lie about real-world fuel economy.

“Writing regulations takes time,” EPA’s director of the Office of Transportation and Air Quality Chris Grundler told the Detroit News. “When you are working in the rapidly changing environment that we’re in right now, we want to make sure that we are agile enough and flexible enough to change with those times.”

Volkswagen may not be the only one that was cheating on their emissions testing. Reports coming out of the European Federation for Transport and Environment are shining light on other manufacturers which could be putting out dodgy emissions figures. I found the Vauxhall Zafira Tourer on one such report and decided to take a look at the Chevy Cruze Diesel due to related engine technology. I was surprised by what I found.

Volkswagen broke the law.

Scratch that. Volkswagen knowingly went out of their way to break the law, did as much as they could to cover up that fact, and only admitted to wrongdoing when the evidence was so heavy that the German giant couldn’t stand under the weight of its own conspiracy.

Nearly 11 million vehicles worldwide — of which 482,000 made their way to the United States — were fitted with a “defeat device” which used a different engine map when being tested for emissions. That device allowed the Volkswagen TDIs to pass sniffer tests on a dyno, but on-road evaluations by the International Council on Clean Transportation showed the four-cylinder diesels were emitting up to 40 times the allowable nitrogen oxides in the real world.

A few things are going to happen. None of it will be pretty. Nobody is going to walk away from this without oily blowback on their faces.

Many in the Volkswagen diesel community are fanatical about their fuel economy and are understandably angry that a fix for the current emissions scandal may see them lose fuel economy in order to lower NOx output. The aftermarket community has provided modifications for the DPF and Adblue systems in the past, meaning there’s good chance they’ll provide parts and tuning to revert any changes Volkswagen may implement on the affected models.
