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:

United States drivers buying fewer Mexican-made cars

Crossovers and pickup trucks are not only growing in market share, they're also more profitable than cars. A crossover on the same platform as a sedan retails for thousands more, despite similar components. It's one of the reasons we've seen automakers rapidly shifting production of their sedans and hatchbacks to Mexico, where cheap labor preserves the thin profit margins on these inexpensive vehicles. But as the market continues to shift in the United States, Mexico is getting burned by its lack of product diversity. The country's auto exports, which are heavy on cars, suffered a 16-percent drop last month, Automotive News reports. In total, year-over-year exports fell from 233,515 to 197,020 last month, while year-to-date exports are down by 7.4 percent, from 922,029 to 854,118. The number one culprit? America – which usually accounts for 75 percent of Mexico's exports – and its appetite for crossovers and pickup trucks bolstered by cheap gas prices. While Mexico does build some light truck models – AN specifically calls out the Ram 2500, Honda HR-V, GMC Sierra, and Toyota Tacoma as export leaders – the vast majority of vehicles rolling out of its factories are sedans and hatchbacks. In fact, the three biggest drops in Mexican exports came from companies whose south of the border factories only build cars – Ford (Fusion/Lincoln MKZ and Fiesta), Mazda (Mazda3), and Volkswagen (Golf and Jetta). Mexican Automotive Industry Association President Eduardo Solis told AN the export shortfall will likely be sorted out sooner rather than later, thanks to a pair of new factories – a Kia car factory and an Audi SUV plant – that are coming online by year's end. The two facilities will add around 100,000 vehicles to the country's export totals, which Solis said should leave the industry on the verge of breaking another export record in 2016. But how sustainable will these record-breaking years be? Slapping an "Hecho en Mexico" sticker on a new German SUV won't be enough to change the fact that Mexico's product mix is tilted too heavily towards body styles that are not growing in volume. Mexico's record-breaking export years probably aren't at an end, but we'd argue they're certainly under threat.

Someone is leaving anti-diesel flyers on Volkswagen TDIs in Portland

As if some Volkswagen TDI owners don't already feel bad enough, given the recent diesel scandal, someone is further shaming them. Flyers full of bad information are being left on TDI cars in eco-friendly Portland, OR. Portland-based sandwich joint Lardo posted a picture of the flyer to their Instagram account yesterday morning. Along with annoying font color changes, the flyer incorrectly states that the diesel car spews two to four times more pollutants than a Chevy Suburban. The author of the flyer also throws a Nazi mention in there for good measure, though they get the history wrong, too. Volkswagen wasn't founded by Nazis, though the Nazi government did create a nationalized car industry to build the 'People's Car', originally designed by Ferdinand Porsche. The factory ended up making war machines instead. Volkswagens weren't really produced until after the fall of the Nazis at the end of World War II. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Volkswagen outfitted their "clean" diesel cars with a device that would only limit emissions during testing. Once on the road, the car spewed 40 times more pollutants than it claimed. The automaker plans to 'refit' 11 million faulty vehicles. Today, the automaker launched a website dedicated to consumers unlucky enough to own the bum vehicles. Eco-warriors aren't the only ones leaving judgmental, passive-aggressive notes on cars. Like this incident in Portland, these notes often fall flat, like when this paralyzed man in Michigan parked in a handicap spot and was accused of stealing the spot simply because he drove his BMW to the gym.
