VW brands excluded from Wards 10 Best Engines for 2016

You definitely won't be seeing a powerplant from Volkswagen or Audi on the 2016 Ward's 10 Best Engines list. In a serious rebuke against them, WardsAuto is excluding all VW/Audi powertrains for at least this year after the German automakers' ongoing emissions regulations evasions. There's no guarantee of the companies returning for 2017, either. In a story on its website, WardsAuto executive editor Tom Murphy writes that the ban lasts "until we are convinced the culture of deceit has been purged, fines have been paid and regulators are satisfied." That could be a while, the way things are looking. The exclusion knocks three powertrains out of the running for this year's list. As a winner last year, WardsAuto would usually test VW's 1.8-liter turbocharged four-cylinder again for 2016. Plus, it planned to check out the 2.0-liter turbocharged four-cylinder from the Audi A6 and the plug-in hybrid from the A3 Sportback E-Tron. In the story, Murphy finds VW's actions particularly despicable because of what they could be doing to the popularity of diesel passenger cars in this country. "BMW, Mercedes-Benz, General Motors, and Fiat Chrysler also sell light-duty diesel engines in the US, but their sales outlook suddenly has grown murky, thanks to VW's shenanigans," he writes. So far, Jaguar Land Rover is remaining confident of US consumers continuing to buy diesel models, though. We'll be able to see the real effects of VW and Audi's ban in a few months because the 2016 Ward's 10 Best Engines will be published December 10. With two major automakers out of the running, their rivals will likely greet this as a better chance to make the grade.

Former Porsche execs acquitted of stock manipulation charges

A German court acquitted former Porsche CEO Wendelin Wiedeking and former CFO Holger Harter of stock manipulation charges, according to Bloomberg. Prosecutors alleged the men hid plans to takeover Volkswagen while publicly denying their intentions to investors. The presiding judge didn't find any merit to those claims, though. "There is nothing to the allegations, absolutely nothing," Judge Frank Maurer said, according to Bloomberg. "There was no secret plan to take over VW." Rather than Porsche taking over VW, the exact opposite eventually happened, and both execs stepped down. Investigators first indicted Wiedeking and Harter for alleged stock manipulation in late 2012. A court in Stuttgart dismissed the case in 2014 because of a lack of evidence, but an appeals court later overruled that decision. The current trial finally began in October 2015. If convicted, Wiedeking faced up to 30 months in prison, and Harter could have received up to 27 months, Bloomberg reported. Prosecutors also wanted one million euro ($1.1 million) fines from them and 807 million euros ($910 million) from Porsche. The acquittal might not be the end of this long-running case, though. In Germany, prosecutors have the right to appeal a ruling, and the lawyer hasn't made a final decision yet. If the court thinks there's a reason, the former execs could be back in front of a judge at some point in the future.

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.
