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 reportedly considering selling Ducati

After shelving numerous motorsport programs and putting less-successful model variants on the firing line, Volkswagen is reportedly considering selling off Ducati, its motorcycle division. Ducati joined the Volkswagen Group under Audi in 2012, and it could be valued as high as 1.5 billion euros. Five years ago, Audi paid roughly $935 million for the motorcycle brand, sources said to Reuters. In 2016, Ducati's sales were worth 593 million euros, or nearly $644 million. There isn't a concrete buyer yet set for the deal, and neither Volkswagen or Audi chose to comment on the matter. Neither did Evercore, the investment banking advisory firm selected to evaluate Volkswagen's options on Ducati ownership. The logic behind jettisoning Ducati is likely to be the same as canceling Audi's LeMans program and VW's WRC racing efforts: Volkswagen is focusing on an electric mobility future, as the shadow of Dieselgate stretches far into the coming years. As Reuters says, the original 2012 Ducati deal may have been a Ferdinand Piech vanity project: "Analysts questioned Audi's purchase of Ducati when it was announced in April 2012, saying the deal had no economic or industrial logic and just reflected former VW Chairman Ferdinand Piech's passion for the Italian company's expertise on design and light engines." Piech is now, however, out at Volkswagen and is also selling a major part of his Porsche stock, making it easier for Volkswagen to ditch the Italian bike brand. Reuters' sources mentioned interested parties as being Chinese or Indian, or interestingly, the consortium led by Prodrive's David Richards which acquired Aston Martin a decade ago.

Tanner Foust checks out his new VW Beetle GRC rally car

Racing driver and Top Gear USA host Tanner Foust is a very busy guy. After all, he's competing in rounds of both Global Rallycross series and FIA World Rallycross Championship, not to mention his TV duties. However, we probably shouldn't feel too sorry for him, because his job puts him behind the wheel of some truly crazy machinery.
Case in point is his latest ride in Global Rallycross - the Volkswagen Beetle GRC. The German company claims that this all-wheel drive Bug makes around 540 horsepower from its 1.6-liter turbocharged four-cylinder and can shoot to 60 in under 2 seconds. Plus, if this video is any indication, this Volkswagen sounds like a machine gun when throwing revs at idle, and it can do some wonderfully easy four-wheel drifts.
Previously, Foust was driving a VW Polo for Andretti Autosport in GRC, but the team unveiled the look of the Beetle GRC at the Chicago Auto Show. Now, Foust is finally getting to show off his new office to the public, and like VW's tagline for the new car claims, it's way hotter than Herbie.
