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 will split EV from combustion unit, seeks partnerships

PARIS — Renault has received several partnership proposals for the combustion engine unit it plans to create alongside one dedicated to electric vehicles and software, two sources familiar with the matter said. Renault plans to separate its electric and conventional car businesses, creating two entities to manage the shift towards fossil-free vehicles. "The group has already received partnership demands" for its internal combustion engine unit, one of the sources said. By bringing in partners on the combustion engine side Renault aims to free up funds to invest in electric vehicles, a technology in which it was a pioneer with Nissan and Mitsubishi, but in which it is now eclipsed by pure players such as Tesla. Renault intends to retain majority ownership of its electric division, which will employ about 10,000 people and which could be bourse-listed via an IPO in the second half of 2023. However, it will only remain a reference shareholder, not a controlling shareholder, of the combustion engine unit, which will have similar staff levels, said two other sources familiar with the plans. One of the sources said Renault may hang on to a 40% stake. Renault declined to comment. The carmaker at a capital market day this autumn will set out its plans for its electric arm based in France and the combustion unit headquartered abroad. That entity will include factories producing engines and gear boxes for gasoline and hybrid cars in Spain, Portugal, Turkey, Romania and Latin America. Among potential partners for its combustion engine business, CEO Luca de Meo in April mentioned Nissan, other automotive groups and long-term investors. De Meo is set to travel to Japan next month to discuss potential Japanese participation in its electric and combustion engine projects. Renault is undergoing a major restructuring aimed at restoring its finances and recently signed partnerships beyond its historical alliances with Nissan, Mitsubishi and Mercedes, such as with China's Geely Automobile Holdings. This month it sold 34% of its South Korean unit to Geely, which owns Volvo Cars and is a shareholder in Mercedes. With Geely, Renault plans to develop hybrid vehicles which will be assembled in its plant in Busan, South Korea. Earnings/Financials Green Mitsubishi Nissan Renault

Mercedes, Renault-Nissan to work together on truck project

Just a few weeks ago, Mercedes-Benz barged into the automotive world with news of a pickup as a mysterious but enticing future model from the German brand. Rumors of a possible collaboration with Nissan followed, but Renault-Nissan Alliance CEO Carlos Ghosn refused to give any clear details. That speculation is now over, because the automakers made their truck partnership official. This new information reveals that the Mercedes truck won't be a full in-house creation from Daimler. For example, the pickup will share some of its underpinnings with the latest Nissan NP300 Navara. The German company's engineers, however, will work to change the design to their liking. Also, as in the rendering, Mercedes will use a double-cab body for the model. "Thanks to our well-established partnership with the Renault-Nissan Alliance, we are able to drastically reduce the time and cost to enter this key segment." Daimler Chairman Dr. Dieter Zetsche said in the company's release. Nissan will play a further major role in the project by helping Renault develop a pickup based on the Navara as well. By 2020, all three trucks will be built together in Cordoba, Argentina, for Latin American markets and in Barcelona, Spain, for other parts of the world. Mercedes will target both regular customers and commercial buyers with its truck. While still not officially slated for North America, there's a chance that the Mercedes truck might be sold here. The US arm of the company reportedly has until the end of the year to decide to offer it with some added luxury-oriented upgrades compared to the rest of the world.
