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:

VW midsize crossover production headed for Chattanooga

Potential labor woes aside, it looks like Volkswagen's Chattanooga, TN factory must have done something that impressed the bosses in Germany, because it sounds like the three-year-old factory is set to score a second model.
The factory currently builds the Passat, and has been in the running alongside VW's Puebla, Mexico factory to build a new crossover vehicle, likely based on the CrossBlue Concept. According to Bloomberg, a pair of unnamed sources have confirmed that Chattanooga is the favorite ahead of an official announcement.
When last we heard about the CrossBlue Concept, word was that a production decision had been delayed over concerns about the three-row CUV's business case. That August 2013 story claimed that a decision regarding the CrossBlue would be pushed back until early in 2014, which means we're ripe for some sort of news, whether good or bad.

Porsche board members facing another ˆ1.8B lawsuit over VW takeover bid

Back in 2008, Porsche got the bright idea that it could take over Volkswagen in the midst of the worst economic slump since the Great Depression. Ignoring that this was a catastrophic move for the Stuttgart sports car manufacturer that that eventually resulted in it nearly going bankrupt and eventually being taken over by the same company it sought to control, the aftermath has left Porsche Chairman Wolfgang Porsche and board member Ferdinand Piëch in the crosshairs of seven hedge funds that lost out during the takeover and are now seeking €1.8 billion - $2.43 billion US - in damages from the two execs, according to the BBC.
See, investors bet on Volkswagen's share price going down, partially because Porsche said it wasn't going to attempt a takeover. But Porsche was attempting to take over VW, having bought up nearly 75-percent of VW's publicly traded shares. When word broke that Porsche owned nearly three-quarters of VW (which indicated an imminent takeover attempt), rather than go down like the hedge funds bet it would, VW's share price skyrocketed to over 1,000 euros per share, according to Reuters.
Naturally, when you bet that a company's share price is going to drop and it in turn (temporarily) becomes the world's most valuable company, you lose a lot of money, unless you're able to buy up shares before prices jump too much. This led to a squeeze on the stock, which the hedge funds accuse Porsche and Piëch (who are both members of the Porsche family and supervisory board) of organizing.
