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.

2023 Japan Mobility Show Mega Photo Gallery: All the highlights and reveals from Tokyo

The 2023 Japan Mobility Show managed to serve up a surprise heap of exciting and futuristic designs and production reveals. Our staff was on the ground in Tokyo for this year's show, where we captured not just all of the latest automotive trends, but some genuinely weird and fascinating stuff.  Browse: Some Delightful Oddities of the 2023 Japan Mobility Show But on to the cars. This year's show featured introductions from Daihatsu, Honda, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Suzuki and Toyota. Some are weird; some are wild; most are probably destined to change significantly before production or merely fade into the void with the rest of the industry's vaporware, but if even a few of these make it to showrooms, we'll consider it a win. Scroll on down for our live galleries of each of the show's major debuts (and cars we're only now seeing in person for the first time).

Nissan reportedly rejecting Renault proposal for closer ties

TOKYO — Nissan Motor Co Ltd will reject a management integration proposal from French partner Renault SA and will call for an equal capital relationship, the Nikkei newspaper said on Monday, citing sources. Nissan's management feels the Japanese company has not been treated as an equal of Renault under existing capital ties, and a merger would make this inequality permanent, the Nikkei reported. The outlook for the alliance — one of the world's top automaking partnerships — has been in focus since the arrest in November of its main architect, Carlos Ghosn, on charges of financial misconduct. The former Nissan and Renault chairman has denied the charges against him and has said he was the victim of a boardroom coup by Nissan executives opposed to closer ties. To which, Bloomberg reported that it has seen emails in which Nissan executives were working with Japanese government officials to defend the company's independence, as Ghosn was pushing for a full merger. The emails indicate growing concern at high levels of the Japanese government, in the months before Ghosn's arrest, that his merger efforts would boost Renault and its largest shareholder, the French government, and harm Nissan, in a relationship the Japanese already saw as lopsided. The emails indicated a desire to keep the existing structure of the alliance with a "re-balancing of the shareholding" to reduce Renault's 43 percent stake in Nissan, and stated that Nissan's independence "should be respected." Nissan declined to comment directly on the emails, while reiterating that misconduct by Ghosn and his former aide, Greg Kelly, is "the sole cause of the chain of events." Renault saved Nissan from the brink of bankruptcy two decades ago and under their current capital alliance, the French company holds greater control over its much larger partner. Nissan Chief Executive Hiroto Saikawa declined to say whether the company had received a merger proposal from Renault. "Now is not the time to think of such things," he told a group of reporters outside of his house in Tokyo. "At the moment we are focused on improving Nissan's earnings performance. Please give us time to do that." Renault declined to comment on the report. Renault has argued in its proposal that an integration would maximize synergies within the French-Japanese alliance, according to the Nikkei. The Financial Times reported last month of Renault's intention to restart merger talks with Nissan within 12 months.
