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.

Renault, Nissan attempt to calm rumors of impending split

TOKYO/PARIS — Shares in Renault recovered some lost ground on Tuesday after the French carmaker and its Japanese partner Nissan rejected media reports that their alliance was in danger of being dissolved. Some have openly questioned whether the alliance can survive without disgraced former CEO Carlos Ghosn to keep the two partners happy.  Renault shares fell to a six-year low on Monday after rumors circulated that its alliance with Nissan was in jeopardy. Nissan shares tumbled to their lowest in 8 1/2 years on Tuesday in Tokyo. At the opening of trading in Paris on Tuesday, Renault shares rose 1.3 percent, before falling back slightly to trade up 0.49 percent by 08:23 GMT. The alliance, which also includes Japan's Mitsubishi Motors, is "solid, robust, everything but dead," the chairman of Renault, Jean-Philippe Senard, told Belgian newspaper L'Echo. A split between the two automotive giants would force both to find new partners in a fast-consolidating industry that is growing increasingly difficult to navigate for independent companies. It will be especially difficult for Renault and Nissan, whose dirty laundry Ghosn intends to air for public consideration.   French Finance Minister Bruno Le Maire also weighed in, saying reports some executives wanted to break up the alliance were "malicious." Speaking to France's CNews TV, he also said he expected Renault to name a new chief executive within days to replace Thierry Bollore, a Ghosn-era appointee who was ousted in October. Luca de Meo, who stepped down as the head of Volkswagen's Seat brand last week, is seen as a frontrunner for the job, although a stringent non-compete clause in his contract firm may prove a hurdle, sources have told Reuters. Nissan, in response to "speculative international media reports," said it was "in no way considering dissolving the alliance." "The alliance is the source of Nissan's competitiveness," the Japanese automaker said in a statement. "Through the alliance, to achieve sustainable and profitable growth, Nissan will look to continue delivering win-win results for all member companies." Concerns emerged about the future of the Renault-Nissan partnership after the November 2018 arrest in Japan of Ghosn, the man who did more than anyone else to hold together the disparate alliance of often-contrasting carmaking cultures.
