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.

Nissan previews new Sport Sedan Concept ahead of Detroit debut

When the Cobo Center opens its doors in a couple of weeks for the Detroit Auto Show, there'll be plenty of new metal on display - and this is the latest.
Nissan announced today that it will bring a new Sport Sedan Concept to the Detroit show, releasing the short statement below accompanied by the teaser image above. Expected to hint at the next Maxima, the concept "previews a new energetic design direction that amplifies Nissan's legendary approach of applying sports car principles to a sedan."
That's about all Nissan is saying for now, so we'll have to wait a while longer to find out more. But the concept will be joined on the show floor by the IDx Freeflow and IDx Nismo concepts that'll be showcased for the first time in North American after their debut at the Tokyo Motor Show over a month ago.

Nissan, Mitsubishi confirm plans to invest in Renault EV unit Ampere

PARIS — Renault's longstanding alliance partners Nissan and Mitsubishi confirmed plans to invest in the French car maker's electric vehicle unit Ampere and use it to develop EVs for the European market, the companies said on Wednesday. After years of contentious partnership, the announcement on Wednesday confirms that the new alliance between the three automakers is smaller and more pragmatic, focusing on regional cooperation. Nissan and Mitsubishi confirmed they would invest respectively up to 600 million euros ($647.46 million) and 200 million euros in Ampere, which has been carved out from the rest of Renault and is due for a public listing next year. Nissan will become "a strategic investor" in Ampere, Makoto Uchida, CEO of the Japanese car marker told reporters, adding the company may use the EV unit's software and connectivity innovations in other markets outside Europe. "Developing electric vehicles all over the world alone would be very challenging," he said. Ampere will develop and manufacture an electric version of the compact Nissan Micra for the European market and a medium-sized electric SUV for Mitsubishi. Renault CEO Luca de Meo said Ampere will cut the costs for the Micra for Nissan by 50%. The alliance partners also confirmed their joint projects in Latin America and India. In September, Renault, Nissan and Mitsubishi ended their common purchasing agreement, which they said would allow them to focus on individual projects and adapt more quickly to regional differences in automotive markets. At the end of July, Renault and Nissan finalised the terms of a restructured alliance after months of negotiations. Talks dragged on for months longer than expected due in part to Nissan, which was concerned about protecting its intellectual property in future collaborations.
