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.

Germany says nein to EU ban on new fossil-fuel cars from 2035

BERLIN (Reuters) - Germany's government will not agree to European Union plans to effectively ban the sale of new cars with combustion engines from 2035, Finance Minister Christian Lindner said on Tuesday. In its bid to cut planet-warming emissions by 55% by 2030 from 1990 levels, the European Commission has proposed a 100% reduction in CO2 emissions from new cars by 2035. That means it would be impossible to sell combustion engine cars from then. European Parliament lawmakers backed the proposals this month, before negotiations with EU countries on the final law take place. Speaking at an event hosted by Germany's BDI industry association, Lindner said there would continue to be niches for combustion engines so a ban was wrong and said the government would not agree to this European legislation. Lindner, a member of the pro-business Free Democrats, which shares power with the Social Democrats and Greens, said Germany would still be a leading market for electric vehicles.

VW's credit ratings could take a beating

In addition to a significant drop in its share price already, Volkswagen's diesel emissions scandal is continuing to have major financial repercussions on the German automaker. According to The Detroit News, credit rating agencies like Standard & Poor's and Moody's changed their forecasts on the company to negative, and Fitch has considered doing so, as well. Volkswagen appears to have the money to cover the costs of this ordeal, but the agencies question the effect that this has in the long term. "Moody's concern, however, is that Volkswagen's alleged breach of US environment rules and, especially, the process by which that breach occurred, will have an adverse effect on its reputation and credibility within the global passenger car markets," the company wrote in a note to investors, according to The Detroit News. VW has initially set aside $7.25 billion to fix things, but the potential shakeup of top executives has caused some investor uncertainty, too. The actual costs for VW to deal with this scandal are still unknown. In the US, the Department of Justice has begun a criminal investigation, and with other automakers the government has settled for $900 million against General Motors and $1.2 billion against Toyota. Attorneys general in 29 states have started looking deeper, according to The Detroit News, and regulators in Europe, South Korea, and Canada have commenced their own probes, as well. Related Video:
