Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Daimler wants to cut EV research spending as it preps EQ

Daimler AG is hoping that the legwork it's done preparing its EQ electric-vehicle sub-brand will allow it to slightly reduce annual spending on plug-in vehicle technology. The Mercedes-Benz parent is looking to cut electric-vehicle research-and-development spending to $13.2 billion in 2017 from about $15.4 billion this year, Bloomberg News says, citing comments Daimler CEO Dieter Zetsche made to journalists in Hamburg, Germany, this week. Daimler's annual R&D spending is up from about $11.5 billion in both 2013 and 2014. Like its competitors – for example Audi and BMW and its i sub-brand – Daimler is aiming to have as much as 25 percent of its annual vehicle sales be battery-electric within the next 10 years as part of an effort to meet stricter greenhouse-gas emissions mandates in both Europe and North America. In fact, Mercedes-Benz and Daimler's Smart division collectively have at least 10 electric-vehicle models on their slates during the next few years, though Zetsche said the German automaker will continue to find ways to make its gas- and diesel-powered vehicles more fuel-efficient as well. Daimler introduced a concept version of the Generation EQ electric SUV at the Paris Motor Show late last month. It comes powered by two electric motors and is made up of a combination of steel, aluminum, and carbon fiber, and boasts a 311-mile single-charge range (on the relatively lenient European testing standards). The SUV also has 402 horsepower, and the ability to go from 0 to 60 miles per hour in less than five seconds. Zetsche said at the time that Daimler was prepping powertrains and platforms for electric sedans, wagons, coupes, and roadsters, in addition to SUVs. Additionally, Daimler's Deutsche Accumotive unit is producing the lithium-ion battery packs for the EQs.

Mercedes forced to lower MPG ratings on two C300 models *UPDATE

*UPDATE: Donna Boland, manager of corporate communications at Mercedes Benz USA, told AutoblogGreen that the sticker change only applied to around 500 C-Class vehicles on dealer lots, since a new C-Class came out in late August. "About 500 are left in the United States, and we've relabeled them," she said. First Hyundai, then Ford and now Mercedes-Benz. The list of companies that have had to change their vehicles' official EPA fuel economy ratings has just grown by one with the announcement that the 2013 and 2014 C300 4-Matic FFV and PZEV versions need to have their EPA labels adjusted. The changes aren't massive, at most one mile per gallon. The changes aren't massive, at most one mile per gallon, but they are lower than before. The FFV version goes from 20 to 19 mpg in the city while the PZEV drops one mpg across the board from 23/20/29 combined/city/highway) to 22/19/28. The FFV's combined (22) and highway (27) ratings stay the same. Other Mercedes vehicles that were spot checked turned out to have accurate labels. The problem, which is reminiscent of the issues that Ford had with the Total Road Load Horsepower, was that "Mercedes underestimated the impact of aerodynamic drag and tire rolling resistance known as 'road-load,'" the EPA said in a statement you can read below. We have asked Mercedes for more information on the issue but have not yet heard back. We're not sure how many vehicles the EPA is retesting (or asking to be retested), but the agency says that the C300 models were evaluated again by Mercedes "with EPA oversight" and the EPA did its own tests at the National Vehicle and Fuel Emissions Laboratory in Ann Arbor, MI. Christopher Grundler, the director of EPA's Office of Transportation and Air Quality, said that the EPA knows that the changes are minimal, but that, "it is important that our oversight system is producing the correct results because even one MPG matters to consumers." In case you need a primer in the recent history of companies adjusting their EPA numbers, check out this and this. Based on today's news, we won't be surprised to hear more changes are coming. EPA Requires Mercedes-Benz to Correct Fuel Economy Labels for Two C300 4-Matic Vehicles WASHINGTON - The U.S. Environmental Protection Agency (EPA) is revising estimates for two 2013/2014 Mercedes C300 4-matic vehicles, the FFV and PZEV, to ensure consumers are given accurate fuel economy values.
