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 Golf R Evo may debut at Beijing Motor Show

If a report in Auto Express is correct, a lighter, faster brother to the Volkswagen Golf R will be shown to the world at the Beijing Motor Show in April. Said to be called the Golf R Evo, the even harder hot hatch would be unveiled as one of those concepts that's practically a de facto presentation of the genuine thing. The Evo in its name will come from having a carbon fiber roof and CF in the bodywork, lighter wheels, thinner bucket seats up front and a roll cage instead of rear seats.
If there's a power increase, it's been described as "a small bump." However, as the report mentions, if the Jenny Craig regimen can drop 100 kilograms (220 pounds) from the the 3,247-pound weight of the European Golf R, then the Golf R Evo will do about the same damage on the scales as the Golf but have at least 50 more horsepower and 44 more pound-feet of torque.
Since we still don't have the current Golf, this isn't something that should keep you awake even if the 'concept' does become a production model. But it is good to know that the Golf R is really going to start pushing its boundaries.

VW spending $10 million on EV infrastructure, calls on Congress for help

It must be the season of big EV infrastructure announcements. In the last few days, we've heard from Bollore in France, PG&E in California and now VW. The German automaker says it will spend a total of $10 million on electric vehicle charging infrastructure by 2016. That includes the previously announced ChargePoint investment VW made with BMW and work the automaker is doing to get chargers for cars like the e-Golf installed as its dealerships. But Jorg Sommer, Volkswagen of America'sl VP of product marketing and strategy, said today in Washington, DC that automakers need help from the federal, state and local governments to turn electric mobility into a thing. Speaking at the 2015 Electric Drive Congress, Sommer said VW would like the Feds to support fast charging networks in urban areas as well as interstate corridors and that governments should "commit to cleaner fleets by purchasing EVs and PHEVs. This should be a US Government priority," he said. He also suggested that the plug-in vehicle multiplier credits under the EPA's greenhouse gas regulations should be extended beyond the 2021 model year. VOLKSWAGEN OF AMERICA TO INVEST $10 MILLION IN ELECTRIC VEHICLE CHARGING INFRASTRUCTURE BY 2016 Feb 10, 2015 Washington, D.C., February 10, 2015 – Jorg Sommer, vice president, product marketing and strategy, Volkswagen of America, today presented Volkswagen's holistic approach to e-mobility surrounding the launch of the zero-tailpipe emissions 2015 e-Golf, including a $10 million commitment to support electric vehicle infrastructure by 2016. During a presentation delivered at the 2015 Electric Drive Congress in Washington D.C., Sommer stated that Volkswagen believes continued legislative support is needed to reach the next level of electric vehicle adoption. "Automakers have effectively delivered electric vehicles that can satisfy the needs of most American drivers," said Sommer. "In addition to the investment we and other companies and industries are making, we would like to see Federal financing support for establishing fast charging networks in urban areas and interstate corridors. We'd like to see more state and federal organizations commit to cleaner fleets by purchasing EVs and PHEVs. This should be a U.S. Government priority, and federal purchasing guidelines should reflect that by giving fleet purchasers the flexibility they need," Sommer said.
