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 suspends sales in South Korea ahead of government meeting

Volkswagen and Audi have announced they will suspend sales of 79 different models in South Korea ahead of a meeting with the country's environmental ministry. VW will halt sales starting on July 25, the same day that its officials are to sit down with the South Korean environmental ministry, which will likely punish the German company. The Wall Street Journal reports that Korea's response to the situation will likely come in the form of an outright sales ban on Volkswagen products by revoking certifications on 79 different models based on 34 different vehicle types. Affected models include the VW Golf, Jetta, and Tiguan and the Audi A3 and A6, the WSJ reports. Essentially, it looks like VW is merely trying to get out ahead of the South Korean government. If the revocation goes through, it'd likely lead to fines and a relatively large recall of around 79,000 vehicles, the WSJ reports. Despite the dreary forecast, Volkswagen reaffirmed its commitment to the South Korean market. "This decision doesn't mean that Volkswagen is pulling out of Korea, which is a very important market to us," a Korean rep for the company said in a statement. "We'll reapply for certification of our cars if the government revokes it. The process may take several months." While Volkswagen's diesel emissions testing scandal is part of the problem, South Korea is taking a harder line than a lot of other countries. Authorities indicted a Volkswagen exec on charges of submitting falsified emissions documents and noise tests last week, while separately, Korea's trade watchdog is considering criminal charges against execs, according to the WSJ. Banning VW Group sales in South Korea isn't quite as dramatic as if the company stopped sales in China, the United States, or Germany, but it's still going to sting. VW Group products (including Bentley) represented around a third of European cars imported by South Korea last year.

VW beams in Star Trek stars to promote e-Golf EV

Volkswagen just set its e-mobility commercial phasers on stunning. The German automaker has cast Captain Kirk and Mr. Spock of Star Trek fame (i.e., actors William Shatner and Leonard Nimoy) in a new advertisement for its growing stable of electric vehicles. Even though it's in German, we think you can get the idea. VW went Hollywood and cast the two veteran actors in a futuristic-themed 45-second ad, which sees Shatner cruise up in the e-Golf (with a toothy Trek-fan kid in tow) while Nimoy rocks the XL1 and the Trek theme blares in the background. Forget for a moment that the kid in the commercial wasn't even born when Shatner started pitching for Priceline, let alone the original Trek series and just enjoy the wholesome good humor of Shatner saying that the electric powertrain is just like the one in a spaceship. If you've got any familiarity with Spock, you should be able to understand his punch line, too. Of course, if you'd rather your German vehicle advertisements were set in the Star Wars universe, we recommend clicking here. VW will bring the e-Golf to the states in November at a price of $35,445, about $6,500 higher than the Nissan Leaf's starting pricetag.
