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 offers to buy back new diesels if bans introduced

By Maria Sheahan FRANKFURT, Germany — Volkswagen will buy back new diesel cars if German cities ban them, it said on Thursday, seeking to reassure potential buyers and stem a plunge in sales of diesel vehicles. Europe's biggest automaker also said it would extend incentives for buyers of new diesel cars. The moves come after a German court ruled last month that cities in the country could ban the most polluting diesel vehicles from their streets. Many German cities exceed European Union limits on atmospheric nitrogen oxide, known to cause respiratory diseases. Fears of bans have led to a plunge in demand for diesel vehicles, which are also key to carmakers' attempts to meet new EU rules on carbon dioxide (CO2) emissions. While diesel cars are heavily criticized for emitting nitrogen oxide, they spew out less CO2 than gasoline equivalents. Diesel car sales plunged 19 percent in Germany last month. At its core VW brand, Volkswagen said its buyback offer applied to new diesels bought between April 1 and the end of 2018 and would kick in if the city in which the buyer lived or worked banned diesels within three years of the purchase. It said its dealerships would buy back diesel vehicles affected by bans at their current value if their owners at the same time bought a new vehicle that was not affected by cities' driving restrictions. At Czech brand Skoda, the guarantee applies to cars bought between April 1 and the end of June, but will cover bans introduced within four years of the purchase date. At premium brand Audi, the offer only covers leased vehicles. Volkswagen also said it was extending to the end of June incentives for customers trading in older diesels for new ones. Fellow German carmaker BMW said earlier this month it would offer to take back leased vehicles if diesels were banned within 100 kilometers (62 miles) of the operator's home or place of work. There has been a global backlash against diesel-engine cars since Volkswagen admitted in 2015 to cheating U.S. exhaust tests. But Germany's government is seeking to avoid widespread bans on heavily polluting diesel vehicles, which companies say could cut the resale value of up to 15 million vehicles in Europe's biggest car market. In Germany, where motorists expect to drive powerful cars on motorways with no speed limits, any restrictions will be unpopular.

Automakers suspend some business in Russia following invasion

(Getty Images)   Global auto and truck makers, including Sweden's Volvo Cars and Germany's Daimler Truck, on Monday suspended some business in Russia following that country's invasion of Ukraine. Russian forces invaded Ukraine last week, marking the biggest attack by one state against another in Europe since World War II. Many firms have idled operations in Russia following Western sanctions against Russia. Energy giant BP Plc, Russia's biggest foreign investor, abruptly announced over the weekend it was abandoning its 20% stake in state-controlled Rosneft at a cost of up to $25 billion. On Monday, Swedish automaker Volvo Cars said it would suspend car shipments to the Russian market until further notice, becoming the first international automaker to do so as sanctions over the invasion continue to bite. In a statement, the company said it had made the decision because of "potential risks associated with trading material with Russia, including the sanctions imposed by the EU and US." "Volvo Cars will not deliver any cars to the Russian market until further notice," it said. A Volvo spokesman said the carmaker exports vehicles to Russia from plants in Sweden, China and the United States. This came as Russia warned Sweden and Finland not to join NATO or risk facing “serious military-political consequences." Volvo sold around 9,000 cars in Russia in 2021, based on industry data. Earlier on Monday, RIA news agency reported Volkswagen had temporarily suspended deliveries of cars already in Russia to local dealerships, citing a company statement. VW had no immediate comment when contacted by Reuters. VW previously said it would halt production for a few days this week at two German factories after a delay in getting parts made in Ukraine. Daimler Truck said on Monday it would freeze its business activities in Russia with immediate effect, including its cooperation with Russian truck maker Kamaz. Mercedes-Benz Group is also looking into legal options to divest its 15% stake in Kamaz as quickly as possible, the Handelsblatt newspaper reported. A Mercedes spokesperson told Reuters business activities would have to be re-evaluated in light of the current events. Mercedes-Benz Group, formerly Daimler AG, was the parent company of Daimler Truck before the truck maker was spun off.
