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 rejig how they manage Daimler partnership, sources say

PARIS — The Renault-Nissan-Mitsubishi alliance is set to scrap a role overseeing ties with Daimler in favor of individual relations with the German group, three sources told Reuters, as they try to better manage a partnership that has not met initial hopes. The shift comes as alliance-level executive Jacques Verdonck, who was in charge of the cooperation with Daimler, retires at the end of the month, the sources familiar with the matter said. France's Renault will instead rely on its head of partnerships, Sandra Gomez, while Nissan will do the same with Catherine Perez. Mitsubishi will also have a person in charge of partnerships, the sources said, adding the bilateral approach was in line with the new "leader-follower" strategy of the alliance. That involves leaning on the strengths of each carmaker in certain areas. Renault and Daimler declined to comment, while Nissan could not immediately be reached for comment. The plan marks another shift following the end of the Carlos Ghosn era at the alliance. The architect of the Franco-Japanese partnership, who also extended the collaboration to Daimler, was arrested on financial misconduct charges in Japan in late 2018, before fleeing to Lebanon in 2019. He denies any wrongdoing. His exit strained already difficult relations between Nissan and Renault, which are now working to get back on track with cost-saving joint production projects among other steps. The partnership with Daimler - which owns high-end brand Mercedes-Benz, contrasting with the more accessible models produced by the others - has also looked in danger of losing steam. Nissan and Renault, both hit by losses, recently sold down their stakes in the German group. Collaborations on Renault's compact Twingo car and Daimler's Smart model are set to end, and some targets for industrial cooperation have been downgraded over the years. But Daimler still has a factory in Mexico with Nissan, and has been exploring the possibility of jointly developing at least one large van model with Renault. An industry shift towards electric vehicles could yet yield other opportunities, one of the sources said. "The collaboration with Daimler is at present made up of Renault-Daimler projects, Nissan-Daimler ones and some between the three," another of the sources said, with yet another saying that the changes reflected a more pragmatic approach.

VW could look outside its own ranks for next CEO

Companies have two options when coming up with succession plans – hire within, or go outside its ranks. Either choice comes with advantages and disadvantages, to be sure. Hiring within means generally getting someone familiar with the company and its culture and traditions, while going outside is ideal if you're looking to shake things up and bring in fresh ideas. It's unclear which avenue the Volkswagen Group will go down when it comes time to replace its head man, Herr Professor Doctor Doctor Herr Martin Winterkorn, but he isn't ruling out a trip outside of Wolfsburg. Winterkorn has already given the reins of the VW brand to former BMW board member Herbert Diess, while Andreas Renschler, a former Daimler board member, is heading up VW's truck group. Now, Winterkorn has made some statements to a German weekly that indicate the most important thing about his successor isn't necessarily his (or her, though no women appear to be on the short-list) previous employer, Motoring.com.au is reporting, so much as his qualities as a leader and an engineering background. "A Volkswagen boss has to have a big affinity to our products. He needs to be close to customers and he needs to have a relationship with dealers," Winterkorn told Stern. "Like always, it depends on the personality and it also helps if the candidate is an engineer." Motoring throws out a couple of potential candidates from within, including Porsche boss Mathias Muller, Audi Chairman Rupert Stadler and engineering guru Ulrich Hackenberg, in addition to both Diess and Renschler. And while each candidate has a lot of potential, the only thing that's guaranteed right now is what Winterkorn has already said: "The decision about who will succeed me is not an easy one for the supervisory board."
