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, Fisker in advanced talks on investment, partnership

Nissan is in advanced talks to invest in electric vehicle maker Fisker in a deal that could provide the Japanese automaker with access to an electric pickup truck while giving the struggling startup a financial lifeline, according to two people familiar with the negotiations. The deal could close this month, said the sources, who asked not to be identified because the talks are ongoing and have not been finalized. Terms being discussed include Nissan investing more than $400 million in Fisker's truck platform and building Fisker's planned Alaska pickup starting in 2026 at one of its U.S. assembly plants, one of the sources said. Nissan would build its own electric pickup on the same platform, the source said. Nissan has U.S. assembly plants in Mississippi and Tennessee. Fisker said on Thursday, when it announced it might not be able to continue as a going concern and would cut 15% of its workforce, that it was in talks with a large automaker for a potential investment and joint development partnership. It did not name the automaker. A Fisker spokesman said the company does not comment on speculation, while Nissan officials were not immediately available to comment. Fisker shares had been down about 45% before the Reuters report but pared those losses and were trading down about 25% with a market capitalization of more than $295 million. The term sheet is ready and the deal is going through due diligence, one of the sources said. Nissan was an EV pioneer with its fully battery powered Leaf hatchback in 2010 but has since struggled in the face of nimbler new entrants. A deal with Fisker would help it move into the growing U.S. electric pickup market. Nissan's talks with Fisker comes in the wake of the former's “rebalanced” relationship with its long-time alliance partner Renault. Last year, Nissan and Renault finalised terms of a restructured alliance after months of negotiations. They aim to have cross-shareholdings of 15% as part of the deal. The more limited alliance removes certain restrictions and has opened the door for Nissan to develop growth plans in areas such as EVs and software independent of Renault, said one of the sources, who is familiar with Nissan's thinking. The Yokohama-headquartered automaker is scouring “many, many opportunities,” the person said.

Recharge Wrap-up: Nissan reveals GT-R LM Nismo, NRG plans eVgo expansion

Nissan has officially revealed the GT-R LM Nismo LMP1 car. The hybrid Le Mans racer uses a biturbocharged 3.0-liter V-6 up front to power the front wheels, plus a kinetic energy recovery system for an extra boost. Football fans likely caught a glimpse of the car in Nissan's With Dad commercial that aired during the Super Bowl, but the company has a couple more videos that show the car off quite well provided below. "This is innovation that excites," Says Nismo president Shoichi Miyatani. "Sustainability is at the top of our agenda, and the technical regulations for Le Mans give us the freedom to pursue new ideas in this area." Read more at Green Car Congress, or in the press release below. The NRG eVgo charging network now operates 120 DC fast charging stations in California. 60 of those are "Freedom Stations," offering both CHAdeMO and CCS charging cables, and 52 more of these are in the works. NRG plans to expand the eVgo network to 25 US markets in the next two years (up from the current 10), including chargers in Tennessee, as well as linking cities along the near entirety of the East and West coasts.

As of now, the Supercharger network extends as far north as Edinburgh, southwest to Exeter, and to Maidstone in the southeast, which is just up the road from access to mainland Europe through the English Channel Tunnel. Tesla operates more than 1,600 Superchargers worldwide at over 300 stations, with 129 stations and more than 670 Superchargers in Europe. Read more at Hybrid Cars.
