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:

Audi exec suspended over diesel scandal

So far, just one lower-level employee has plead guilty in the ongoing VW diesel scandal. Up high, the VW CEO when the scandal broke, Martin Winterkorn, resigned right after the news came out. Other executives have also quit or been suspended as well. Today, we learn that one more executive is feeling the heat a year into the scandal. Stefan Knirsch, the head of technical development at Audi and Audi board member, is going to be suspended from his position this week because of his ties to the technology that VW Group used to cheat emissions tests. The German newspaper Bild Am Sonntag reports that Knirsch not only knew that the cheating software existed but also lied about it under oath. Knirsch previously worked at Porsche and then Audi's electrification division. He left Audi's EV efforts behind in early 2015.

Volkswagen officially grants access to UAW in Tennessee

An audit at the Volkswagen factory in Chattanooga, TN has revealed that at least 45 percent of the facility's workers support unionization, leading the German company to grant access rights to the United Auto Workers. This is a tremendous step in the UAW's long-running and at times contentious pursuit of the workforce at Chattanooga. With this latest move, "local leadership is ready to move forward with additional conversations with the company," the union said in a statement obtained by The Detroit News. "As a starting point, UAW Local 42 will take advantage of the company's offer to establish bi-weekly meetings with Volkswagen Human Resources and the Volkswagen Chattanooga Executive Committee." The News reports that UAW Secretary-Treasurer Gary Casteel, shown above speaking at the Chattanooga plant last summer, claimed these meetings "will remind Human Resources and the Chattanooga Executive Committee of the mutually agreed-upon commitments that were made by Volkswagen and the UAW last spring in Germany. Among those commitments: Volkswagen will recognize the UAW as the representative of our members. We believe Volkswagen made this commitment in good faith and we believe the company will honor this commitment." It's important to note that despite Casteel's remarks, this is not a collective-bargaining agreement, Harley Shaiken, a labor professor at University of California, Berkeley, told The News. "But it is a step in the direction of recognition, which ultimately could lead to collective bargaining. This is not the end point," Shaiken said. "We don't know what's next. We're in unchartered territory."
