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:

Autoblog's Editors' Picks: Our complete list of the best new vehicles

It's not easy to earn an “EditorsÂ’ Picks” at Autoblog as part of the rating and review process that every new vehicle goes through. Our editors have been at it a long time, which means weÂ’ve driven and reviewed virtually every new car you can go buy on the dealer lot. There are disagreements, of course, and all vehicles have their strengths and weaknesses, but this list features what we think are the best new vehicles chosen by Autoblog editors. We started this formal review process back in 2018, so there's quite of few of them now. So what does it mean to be an EditorsÂ’ Pick? In short, it means itÂ’s a car that we can highly recommend purchasing. There may be one, multiple, or even zero vehicles in any given segment that we give the green light to. What really matters is that itÂ’s a vehicle that weÂ’d tell a friend or family member to go buy if theyÂ’re considering it, because itÂ’s a very good car. The best way to use this list is is with the navigation links below. Click on a segment, and you'll quickly arrive at the top rated pickup truck or SUV, for example. Use the back button to return to these links and search in another segment, like sedans. If youÂ’ve been keeping up with our monthly series of the latest vehicles to earn EditorsÂ’ Pick status, youÂ’re likely going to be familiar with this list already. If not, welcome to the complete list that weÂ’ll be keeping updated as vehicles enter (and others perhaps exit) the good graces of our editorial team. We rate a new car — giving it a numerical score out of 10 — every time thereÂ’s a significant refresh or if it happens to be an all-new model. Any given vehicle may be impressive on a first drive, but we wait until itÂ’s in the hands of our editors to put it through the same type of testing as every other vehicle that rolls through our test fleet before giving it the EditorsÂ’ Pick badge. This ensures consistency and allows more voices to be heard on each individual model. And just so you donÂ’t think weÂ’ve skipped trims or variants of a model, we hand out the EditorsÂ’ Pick based on the overarching model to keep things consistent. So, when you read that the 3 Series is an EditorsÂ’ Pick, yes, that includes the 330i to the M3 and all the variants in between. If thereÂ’s a particular version of that car we vehemently disagree with, we make sure to call that out.
