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.

Mercedes and VW battling Uber and Apple to spend billions on Nokia mapping division

Whether for autonomous driving or simply better navigation, digital mapping is closely linked with the future of motoring. The sale of a major player in that industry is spurring a showdown between automotive behemoths and tech giants, and it's a fascinating battle to watch unfold. Nokia is selling its Here mapping division, and while the company might not have the name recognition of Google, it controls about 70 percent of the auto market. The business is valued at $785 million, according to Reuters, but is likely to sell for significantly more. Case in point: Uber reportedly submitted a $3 billion bid. Apple has also been rumored to be among those interested in purchasing Here. A trio of German automotive heavyweights is mounting a challenge to Silicon Valley, though. According to Reuters speaking to two unnamed insiders, Daimler, BMW, and Audi are teaming up to submit a joint bid for an undisclosed sum. They're worried that if Here falls under the control of tech companies, then automakers might have limited availability to these vital maps in the future. Nokia bought Here for $8.1 billion in 2007, according to Reuters. The company operates a fleet of vehicles with cameras and LIDAR that drive around the world to create high-definition maps. It also generates even more information by using the GPS data from shipping and trucking companies.

AMG-powered Aston Martins still years away

After flirting for several years, Mercedes-Benz and Aston Martin have finally tied the knot. Just don't expect to see any offspring to result from the union for at least three or four years.
This according to Auto Express, which spoke with Daimler chief Dr. Dieter Zetsche at the Frankfurt Motor Show last week. AE reports that a new range of AMG-developed turbocharged V8s, transmissions and electrical components will make their way into the successors to the current V8 Vantage and DB9, but that these models are still a few years off.
Purists might balk at the thought of a Mercedes-powered Aston holding true to the brand's heritage. But while David Brown (for whom the DB range is named) may have steered clear of shoehorning in Detroit muscle into his cars, the entirety of the company's current range is powered by engines borrowing technology from Ford, and that arrangement seems to have worked well for Aston until now. And if you're still skeptical, look no further than Pagani and its AMG-sourced engines and you should have all the proof you need that the new relationship between Daimler and Aston could be a success.
