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.

Audi, BMW, Daimler buy Nokia's Here digital mapping business

The fight for control of Nokia's Here digital mapping service appears to have drawn to a close as a consortium of German automakers has announced a deal to jointly acquire the business from the Finnish telecom giant. As anticipated, ownership in Here will now be taken over jointly by Audi, BMW, and Daimler, beating out reported rivals bids from the likes of Apple and Uber. Here is one of the largest and most advanced digital mapping and location systems. It started out in Chicago in 1986 as Navteq before Nokia acquired it in 2007, and is now slated to change ownership again. The cloud-based service maintains high-definition digital maps for nearly 200 countries and supports over 50 languages, gathering data from users to update the data continuously. Rather than transition the service into their own proprietary technology, however, the automakers insist that it will remain open "to all customers from the automotive industry and other sectors." Ownership will be shared equally between the three companies, with "none of them seek[ing] to acquire a majority interest" in Here. For another, Here's management is promised to remain independent, and "the consortium will not interfere into operational business." Though the purchase price has not been disclosed, it is rumored to be worth in the neighborhood of $2.7 billion. Assuming it passes regulatory approval, the acquisition is slated to be completed in the first quarter of next year. The German automakers anticipate implementing the service to provide connected vehicles with accurate, up-to-date information on road and other conditions. Examples it outlines include warning other drivers of icy conditions based on outside temperature and ABS activation. It could also warn drivers of impending traffic jams, or even guide traffic through green lights in an urban environment. In the future, the highly detailed maps are envisioned to enable fully automated driving as well.

Experience the New York Auto Show by drone

The Autoblog team recently returned from wildly running around the Javits Center to cover all the news and debuts at the New York Auto Show. Sometimes, it's nice to take a more serene look at the exhibition floor, though, and the event's organizers are providing that exact opportunity by flying a drone through the hall. Combined with the down-tempo music, this clip feels like a form of automotive meditation. If you're going to miss the show in the Big Apple, the drone also provides a good overview at the exhibition floor, especially at the stands from Lexus, Buick, Dodge, Mercedes-Benz, Toyota and BMW. Plus, it's a fun way to see some vehicles from a completely different angle than they ever appear on the road.
