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:

South Korea to file criminal charges against VW exec

South Korea has tossed out Volkswagen's recall plans and is preparing to level criminal charges over its handling of the diesel emissions catastrophe, The Wall Street Journal reports. "Recall plans the company submitted to us earlier this month were insufficient and lacked key information, and thus are unacceptable," the South Korean Ministry of Environment said in a statement obtained by the WSJ. A ministry official hinted at the possibility of criminal charges earlier this month if VW's recall plan wasn't satisfactory, the Yonhap News Agency reports, and now it looks like it will actually follow through. According to the WSJ, South Korea has already ordered VW to recall 125,000 vehicles and slapped the automaker with a $12.3 million fine – one of the many countries to do so – but if it follows through with criminal charges against the company or its employees, it'd be among the earliest to so. Other countries, including the United States, are still exploring the possibility of criminal charges. Charges would likely come against both Audi Volkswagen Korea and its managing director, Johannes Thammer. It's not clear what the actual charge would be, but the WSJ claims Thammer could be facing up to five years in prison and a fine of 30 million won (around $24,700 at today's rates). For its part, VW officials in South Korea maintains that it is "doing its utmost to resolve the emissions issue" and that it plans to "offer further explanation" to authorities regarding its proposal for an emissions and fuel mileage fix in that country.

Lamborghini and Bentley may hold off on SUVs so VW can conserve cash

After surveying the European economic scene, Volkswagen may have decided now is not the time to launch utility vehicles with Bentley and Lamborghini badges. Bentley officials say they will continue to push for support for the EXP 9 F and Lamborghini CEO Stephan Winkelman has said planning for the Urus will continue until VW tells it to stop.
That decision could come on November 23, when VW's board will vote on the company's budget for equipment, factories and vehicles. With VW's sales slowing and the Euro economy slumping further, some industry watchers say the company is more likely to build its cash reserves than to introduce super-expensive luxury SUVs or crossovers.
"Such vehicles are anything but obligatory during a crisis," says Frankfurt-based Equinet AG analyst Tim Schuldt in a new Automotive News Europe story. "Delaying their launch would be no drama but help save costs."
