VW Golf R 400 reportedly green-lit (again)

After speaking to Volkswagen powertrain boss Dr. Heinz-Jakob Neusser at the 2015 New York International Auto Show, we uncovered that the Volkswagen Golf R 400 would be sold in the United States... if it ever made it to production at all, that is. That prerequisite looks like it's about to be fulfilled, as the same good doctor that said the super-powered GTI would come to the US has confirmed to Car that development is currently underway. This follows up on reports from late 2014 that the 400-horsepower car would make production. "We have the Golf more sporty than ever before, since we soon will have the Golf R 400 – we will do this car," Neusser told Car. "We are in fact in development of it right now." That is, we think you'll agree, splendid news. Of course, it also begs the question of when the new car will arrive. According to Car, it'll be just "a few short months," indicating that the Frankfurt Motor Show will likely host the Golf R 400's debut later this year. Whether that proves correct, though, likely won't be clear until later this summer.

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:

Matthias Muller officially named VW Group CEO

While the vast number of rumors made it seem like a foregone conclusion, Porsche boss Matthias Muller has officially been named Volkswagen Group CEO to replace the recently resigned Martin Winterkorn. His contract runs through the end of February 2020, and until a replacement is found, Muller also gets to hang onto his old job as chairman of Porsche. At the same time, the VW Group Supervisory Board is announcing a massive structural reorganization across the entire company, with the new management model in place by the beginning of 2016. Contrary to previous rumors, Michael Horn remains as President and CEO of VW Group of America. The board wants a greater emphasis on brands and regions going forward, and the scale of this shift can be seen in the US. On November 1, VW Group business in the US, Mexico, and Canada is being combined under the leadership of current Skoda chairman Winfried Vahland. However contrary to previous rumors, Michael Horn remains as President and CEO of VW Group of America. Other brands are also seeing some significant changes mechanically. Porsche, Bentley, and Bugatti now fall under the Group's "sportscar and mid-engine toolkit." This means that the brands will start sharing standardized technical parts. A Chief Technical Officer across all of the company's brands will also start working toward future innovations. The new brand-centric view means the end of a group-wide production department. "Going forward, the brands and regions will also have greater independence with regard to production. So it follows that they should also hold the responsibility for these activities," Berthold Huber, interim Chairman of the Supervisory Board, said in the announcement. In a statement with the press release about his promotion, Muller promised to turn the company around after such an international crisis. He said: "My most urgent task is to win back trust for the Volkswagen Group – by leaving no stone unturned and with maximum transparency, as well as drawing the right conclusions from the current situation. Under my leadership, Volkswagen will do everything it can to develop and implement the most stringent compliance and governance standards in our industry." Matthias Muller appointed CEO of the Volkswagen Group Muller remains Chairman of Porsche AG until a successor has been found Matthias Muller (62) has been appointed CEO of Volkswagen AG with immediate effect.
