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 of America boss Horn was aware of diesel cheat 18 months ago

We're just going to make a prediction: Volkswagen of America boss Michael Horn's congressional testimony, slated to begin today, is not going to go well. Based on a written testimony submitted by Horn, the exec is expected to tell Congress he knew his company was violating emissions regulations at least 18 months before it actually came clean. "In the spring of 2014... I was told that there was a possible emissions non-compliance that could be remedied," Horn wrote, in testimony published on the US House of Representatives' website (PDF warning). "I was informed that EPA regulations included various penalties for non-compliance with the emissions standards and that the agencies can conduct engineering tests which could include 'defeat device' testing or analysis. I was also informed that the company engineers would work with the agencies to resolve the issue." Horn's written testimony went on to outline how the company will "develop a remedy for our customers." It includes five points, ranging from the "world-wide investigation" being conducted by the company to reassurances that VW's engineers are "working tirelessly" on fixes to the four-cylinder diesel problems. Horn went on to confirm that each generation of the affected diesel – there are three – will require its own distinct fix. Finally, Horn went on to say that the company will "examine our compliance, processes, and standards" to prevent a repeat of the diesel catastrophe, while promising "open communication with our customers, dealers, employees, and the public as we move forward." We've included Horn's complete, three-page written testimony below. Have a look. Testimony of Michael Horn, President and CEO of Volkswagen Group of America, Inc. Before the House Committee on Energy and Commerce Subcommittee on Oversight and Investigations October 8, 2015 Chairman Upton, Chairman Murphy, Ranking Member Pallone, Ranking Member DeGette, other Members of the Committee, thank you for inviting me to testify before the Committee today. My name is Michael Horn, and I am the President and CEO of Volkswagen Group of America, a subsidiary of Volkswagen AG, headquartered in Wolfsburg, Germany. I have volunteered to come before this Committee at the very outset of these inquiries in an effort to show our commitment to cooperation. We have not had the opportunity to review all aspects of this matter, indeed the investigation is just beginning.

VW reveals Outback-rivaling Golf Alltrack ahead of Paris

The Volkswagen Passat Alltrack is getting a baby brother at this year's 2014 Paris Motor Show in the form of a new Golf Alltrack. Like its larger sibling, the little wagon is supposed to offer light-duty off-road driving ability combined with a more rugged look to show it off.
To give the Golf Alltrack that soft-road ability, VW is outfitting the wagon with its latest 4Motion all-wheel drive system from Haldex. The setup can decouple power from the rear-axle when not needed to save fuel. To further improve traction, the Alltrack gets VW's electronic differential lock, and the car can individually brake its inside wheel during hard cornering for better handling.
Volkswagen also wants the Alltrack to be able to visually show that it can handle getting away from the pavement, even though it starts life as a standard Golf wagon. That means jacking up the suspension an extra 0.75 inches and adding black moldings all the way around the car. There are also redesigned bumpers for the front and rear and silver underbody protection, plus new accents like anodized roof rails and silver mirror caps. The interior is essentially unchanged from the wagon, except for altered trim and Alltrack badges.
