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, Suzuki mulling rekindling relationship in face of legal battle

Volkswagen and Suzuki have been undergoing marriage counseling in a bid to avoid finalizing their nasty divorce. The blissful union has been troubled for some time, with Volkswagen claiming that it could affect operational decisions at Suzuki, and the Japanese brand's sniping and constant flirting with a certain Italian temptress causing rifts.
The matter first went to court in 2012, when Suzuki demanded VW get out, and leave its 19.9-percent stake in the Japanese brand in a box to the left. Now, Automotive News is reporting that the company will give the relationship one last shot, according to closed-door dealings between the two in London.
Still, it's understood that VW and Suzuki recognize the benefit of their alliance, and that it'd be in the best interests of the kids both parties to make things work. Spokespeople declined to comment to AN, but the newsmagazine spoke with Frank Biller, an analyst for LBBW in Stuttgart, who said, "Both companies stand to benefit if they can overcome the disagreements over leadership claims."
