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 confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models. Scroll down for a press release highlighting the automaker's future fuel-saving initiatives.

Everyone but VW and Tesla has recalled their Takata airbags

Takata's massive airbag inflator recall affected over 32 million vehicles from 11 automakers in the US, but two companies buying the supplier's parts haven't been affected so far: Volkswagen and Tesla. There are 887,055 VWs and 184,926 Teslas using Takata's inflators with ammonium-nitrate propellant, a new accounting shows, according to Automotive News. That doesn't necessarily mean the models need to be recalled. These figures came from a report that Takata prepared for the National Highway Traffic Safety Administration, which listed all of the vehicles it supplied with ammonium nitrate-fueled inflators. The substance is believed to be linked with the components' rupturing, along with manufacturing defects and humidity. "We're not asking because we've got reports of problems; we just need to figure out what the universe is," NHTSA spokesman Gordon Trowbridge said to Automotive News. Takata reportedly told Tesla that the inflators in its EVs are not affected with these problems, and VW is investigating a case in June where a side airbag allegedly burst in a 2015 Tiguan, Automotive News reports. The government is also still researching the precise cause of the parts' ruptures. If the investigation finds ammonium nitrate to be a factor, the vehicles could need recalled. During a Congressional hearing Takata vice president Kevin Kennedy admitted that ammonium nitrate could be among the factors of the ruptures, but the company has continued to use the chemical in its inflators. Takata is now working to transition to a different propellant. Related Video:
