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. Go to YouTube and read the lengthy comments on the video left by Andrew Price for a more thorough dissection of what could explain TFL's disparities. You can watch the video above, and feel free to try and dissect the results yourselves in the comments below. Related Video:

In wake of Volkswagen scandal, cheating may actually get easier

The three crises that rollicked the auto industry in recent months – a rising death toll related to the General Motors ignition-switch defect, the Jeep Cherokee hack and now the Volkswagen cheating scandal – all have one thing in common. Outsiders discovered the problems. In the new matter of Volkswagen rigging millions of cars to outsmart emissions tests, researchers at West Virginia University and the International Council on Clean Transportation first spotted irregularities. In the hacking of a Jeep Cherokee, it was independent cyber-security researchers Chris Valasek and Charlie Miller who found and reported cellular vulnerabilities that allowed them to control a car from halfway across the country. And lest we forget in the case of General Motors, it was a Mississippi mechanic and Florida engineer who first made connections between non-deploying airbags and faulty GM ignition switches that had been altered over time. They worked on behalf of Brooke Melton, a 29-year-old Georgia woman killed in a Chevy Cobalt. "That argument is built on a whole string of trusts, and now it is clear that we should absolutely not be trusting." - Kyle Wiens Amid the Volkswagen scandal, the role these independent third parties played in unearthing life-threatening problems is important to highlight, not only because it shines a light on the ethical indifference corporations paid to life-and-death problems of their creation. The role of the independents is noteworthy because, just as their contributions never been more relevant in protecting the driving public, they could soon be barred from the automotive landscape. Since May, a little-known but critically important process has been playing out before an office within the Library of Congress, which will soon decide whether independent researchers and mechanics can continue to access vehicle software or whether that software, which runs dozens of vehicle components, is protected by copyright law. The Digital Millennium Copyright Act criminalizes measures taken to circumvent security devices that protect copyrighted works. When the DMCA was signed into law in 1998, it was intended to protect the likes of movies from being pirated and companies from ripping off software. At the time, few had a clue that some 17 years later cars would essentially be mobile software platforms run by millions of lines of code that potentially fall under the law's jurisdiction.

German judge 'inclined to dismiss' hedge fund lawsuit against Porsche

Last year, around two dozen investors, including hedge funds, leveled a 1.4 billion euro ($1.95 billion at the time) lawsuit against Porsche in connection with the automaker's attempted takeover of Volkswagen in 2008. The Stuttgart Regional Court dismissed the case. Around 19 of those plaintiffs are heading back to court to appeal the ruling and still hope to get 1.2 billion euros ($1.4 billion). However, according to one German judge, the chances for success aren't any better this time around. "On balance it's our view that we consider the lawsuit, or the appeal, to be unpromising for several reasons," Gerhard Ruf, a judge in Stuttgart, said to Reuters. "We are inclined to dismiss the case." The court's ruling on the appeal will be announced on March 26. The investors' case hinges on Porsche's strategy surrounding the botched takeover. The sports car maker said that it wasn't trying to control VW, when in fact it was. These hedge funds had bet against Volkswagen stock, but the share price surged when Porsche's plan inevitably came to light. Investors have sued the sports car company multiple times since then in attempts to recoup billions of dollars. However, none of the lawsuits have been successful, whether attempted in the US or Germany. Former Porsche CEO Wendelin Wiedeking and and CFO Holger Haerter might still stand trial for the alleged stock manipulation, though.
