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:

Volkswagen Routan dead, pour out a sippy cup for your little homies

America's minivan wolfpack has just gotten smaller by one. According to Automotive News, Volkswagen officials have confirmed what we've suspected for some time - the Routan is dead. Essentially a lightly reworked version of the Dodge Grand Caravan, the Routan actually hasn't been rolling off of Chrysler's Windsor, Ontario production line at all this year, but VW had yet to confirm its discontinuation. However, Jonathan Browning, CEO of VW America, has reportedly admitted that the Routan is being axed, with remaining units expected to be funneled into corporate functions for "internal purposes."
The move isn't unexpected - the Routan has never been a big seller, with just 57,650 examples moved since sales began in 2008 - peak yearly sales totaled under 16,000 units, and that was back in 2010. And while many have talked of the minivan segment shrinking, Automotive News points out that the segment actually grew 14 percent last year to 597,118 units, though it should be noted that most segments have been on sales upticks as the US economy chugs out of its recession.
So, is volume-crazy Volkswagen prepared to pass on large family vehicle sales? Probably not - the German automaker has signaled that it plans to build a three-row crossover in North America soon, and we wouldn't be surprised if it looks an awful lot like the Crossblue Concept from January's Detroit Auto Show - minus the fancy plug-in diesel powertrain.
