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.

'Zero' chance of Renault taking over Nissan, Mitsubishi, says Ghosn

TOKYO — Renault SA absorbing Nissan Motor Co. and Mitsubishi Motors Corp is not an option as the carmakers look to strengthen their partnership while retaining their autonomy, alliance chairman Carlos Ghosn said on Friday. "Anybody who will ask Nissan and Mitsubishi to become wholly owned subsidiaries of Renault has zero chance of getting a result," Ghosn told shareholders of Mitsubishi Motors at a meeting. He also serves as chief executive of France's Renault. The alliance was the world's top-selling passenger vehicle maker in 2017, but as the global auto industry consolidates, it is looking to strengthen its position before the 64-year-old Ghosn, its main architect, retires in the coming years after overseeing the partnership for nearly 20 years. We reported in March that the carmakers were discussing a deeper tie-up, which could see the French government, a major shareholder in Renault, give up influence at Renault and the French carmaker relinquish control over Nissan. The three automakers have a unique partnership designed to leverage their combined scale to save on costs including R&D, parts procurement and production to better compete with rivals Volkswagen AG and Toyota Motor Corp. They are also interlinked by their shareholding structure. Renault holds 43.4 percent of shares in Nissan, while Nissan owns 15 percent of Renault, with no voting rights in a partnership that began in 1999. Mitsubishi Motors joined the alliance in 2016 after Nissan took a 34 percent controlling stake in the smaller automaker. Nissan CEO Hiroto Saikawa has said the alliance is not discussing a "full merger." Ghosn said that while the focus of the alliance was to sell more cars and increase profitability by reducing unnecessary duplication of processes, he wanted each of the three automakers to maintain their independence, which differentiated the group from Toyota and Volkswagen. "We need to work together ... to find a system by which what we have today, which is working very well, can continue in the future no matter who is leading the alliance," he said. "We need to prove that this is sustainable five years down the road, 10 years down the road, 15 years down the road." In a Figaro interview published last week, Ghosn was upbeat about the prospect of securing a new deal for the alliance despite its extreme political sensitivity in France and Japan, saying a plan would need to be announced "well before" the end of his four-year term at the helm of Renault in 2022.

Nissan, Kia under investigation over occupant detection systems

Kia and Nissan are facing separate investigations by the National Highway Traffic Safety Administration because of alleged problems with the occupant detection systems in their vehicles' airbags. The larger investigation is NHTSA's new engineering analysis into 986,826 Nissan and Infiniti vehicles. They include the 2013 Nissan NV200 and 2013-2014 Altima, Leaf, Pathfinder, and Sentra. Among the Infinitis, there are the 2013 JX35 and 2014 Q50 and QX60. Owners allege the occupant classification system can misidentify passengers and turn off the airbag if they don't weigh enough. Nissan recalled over a million vehicles worldwide last year to fix the same problem with a software update, but NHTSA kept getting complaints about the issue after the repair. The agency opened a preliminary evaluation in March, and after 1,271 complaints it has now been updated to an engineering analysis. The Feds intend to evaluate the effectiveness of Nissan's solution. NHTSA is also opening a preliminary evaluation into the 2007-2009 Kia Spectra for the occupant classification not working properly, and it could affect an estimated 186,000 of these vehicles. The government agency has 43 complaints from people allegedly reporting the failures. According to NHTSA, the issue could result in the airbag not deploying with enough force or not activating at all in an accident. This investigation is meant to assess the scope of the potential flaw, and there's no recall yet. INVESTIGATION Subject : Occupant Classification System Fault Date Investigation Opened: SEP 01, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15031 Component(s): AIR BAGS All Products Associated with this Investigation Vehicle Make Model Model Year(s) KIA SPECTRA 2007-2009 Details Manufacturer: Kia Motors America SUMMARY: The Office of Defects Investigation (ODI) has received 43 complaints alleging a malfunction of the front passenger seat occupant classification system (OCS) in 2007-2009 Kia Spectra vehicles. The complaints report illumination of the SRS (air bag) warning light. All of the complaints allege the cause of the light illumination to be a malfunction of the OCS sensor mat imbedded in the passenger seat cushion, and/or report the presence of diagnostic trouble code B1448 which relates to the OCS sensor mat also. Many of the complaints note the malfunction occurred after the warranty period expired and mention high repair costs as a major deterrent to repairing the vehicle.
