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:

Peugeot will prove it doesn't offer cheater diesels

Our diesels are clean, really. That's the message from French automaker PSA/Peugeot-Citroen as it plans to go on the offensive in response to Volkswagen's diesel-emissions scandal. PSA will go out of its way to prove its diesels are as clean as advertised. The company is looking at disclosing "real-world" fuel-economy statistics as soon as next spring and will use an independent entity to vet the numbers, Automotive News Europe says, citing comments that PSA/Peugeot-Citroen financial chief Jean-Baptiste de Chatillon made to reporters this week. Such efforts may be vital, since roughly two-thirds of the vehicles Peugeot-Citroen sells in Europe are powered by a diesel engine. Last month, VW admitted that as many as 11 million of its diesel-powered vehicles were programmed with software designed to cheat emissions-testing systems. The news shook up the industry, especially companies that sell a good chunk of diesels. The EU itself may start instituting "real world" fuel-economy and emissions testing as soon as 2017. French regulators have said they may eliminate diesel-fuel subsidies that currently make diesel fuel cheaper to customers than gas. That adjustment may occur as soon as next year, since it's been pushed up in response to the VW scandal. Peugeot-Citron continues to reiterate that it has never installed software that was designed to cheat emissions-testing systems. Additionally, the automaker was more than a decade ahead of European Union mandates for engine components designed to cut soot emissions, so the company is hoping its track record makes a difference. It wants to be perfectly clear about that.

VW stock delisted from Dow Jones Sustainability Index

Because of the company's years-long diesel emissions evasions, Volkswagen AG is being removed from the Dow Jones Sustainability Indices effective October 6, according to a joint statement by S&P Dow Jones Indices LLC and RobecoSAM. After looking at reports of the automaker's cheating software, the DJSI has decided that the company shouldn't be part of the index anymore. According to The Detroit News, the DJSI is meant to track the top 10 percent of companies that are considered leaders environmentally and socially in each industry among the 2,500 largest companies in the S&P Global Broad Market Index. This de-listing means that VW is no longer considered an industry leader by this group for its economic, environmental and social performance. As of this writing, VW AG's stock price sits at 97.75 euros ($109.14), and the figure has been largely in freefall since the emissions evasions reports first surfaced. It was considered shocking on September 21 when the shares plunged almost 18 percent to end the day at 132.15 euros ($147.57). According to The Detroit News, the automaker has lost about $30.8 billion in value since the EPA put out its notice of violation on September 18.

A review of VW's standing in the DJSI was prompted by the recent revelations of manipulated emissions tests. Per the published and publicly available methodology for the DJSI, potential problematic issues relating to any DJSI component company automatically trigger a Media & Stakeholder Analysis (MSA), which examines the extent of the respective company's involvement and how it manages the issue. Following the MSA, the Dow Jones Sustainability Index Committee (DJSIC) reviews the issue and decides whether the company will remain in the index, based on DJSI Guidelines. In VW's case, the DJSIC reviewed the situation and ultimately decided to remove the Company from the DJSI World, the DJSI Europe, and all other DJSI indices. The stock will be removed after the close of trading in Frankfurt on October 5, 2015, thus making the removal effective on October 6, 2015. As a result, VW will no longer be identified as an Industry Group Leader in the "Automobiles & Components" industry group.
