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.

Nissan tells Renault it is 'not opposed' to Fiat Chrysler merger plan

TOKYO – Nissan on Wednesday told Renault it wasn't opposed to its partner's potential $35 billion merger with Fiat Chrysler, the Nikkei newspaper said, as the two met to hash out the future of their alliance amid a deal that could upend the auto industry. The leaders of Nissan Motor Co, France's Renault SA and junior partner Mitsubishi Motors Corp gathered at Nissan's headquarters in Yokohama for a scheduled alliance meeting - one overshadowed by Fiat Chrysler's proposal this week for a merger-of-equals with Renault. The plan, which would create the world's third-largest automaker, raises difficult questions about how Nissan would fit into a radically changed alliance. Renault Chairman Jean-Dominique Senard arrived in Japan on Tuesday to discuss the proposed tie-up with Nissan, 43.4% owned by the French automaker. "We are not opposed," the Nikkei quoted an unnamed Nissan source who had attended the meeting as saying. The person also said "many details need to be worked out" before the Japanese automaker solidifies its position on the issue, the Nikkei reported. In a statement, the alliance members confirmed that they had "an open and transparent discussion" on the proposal. The deal looks designed to tackle the costs of far-reaching technological and regulatory changes, including the drive toward electric vehicles. Nissan, which has rebuffed overtures by Renault for a merger of their own despite their 20-year alliance, was blindsided by the discussions, sources have told Reuters, stoking concerns that a deal with Fiat Chrysler could weaken Nissan's relations with Renault. The tie-up also poses an additional challenge for Nissan CEO Hiroto Saikawa, already grappling with poor financial performance and an uneasy relationship with Renault after Nissan led the ousting last year of long-standing alliance chairman Carlos Ghosn. There have long been tensions between Nissan and Renault over the imbalance of power in their alliance. Nissan, the bigger company, holds a 15% non-voting stake in the French automaker, while Renault owns 43.4% of Nissan. Ahead of Wednesday's meeting, Japanese media quoted Saikawa as telling reporters that he would look at the potential opportunities afforded by a Renault-FCA merger. Credit ratings agency Moody's said it was vital for Nissan to stabilize its partnership with Renault to expand operational synergies and improve margins.

Chrysler, Nissan minivans earn 'dire' crash test results, says IIHS [w/video]

First introduced in 2012, the Insurance Institute for Highway Safety's small-overlap frontal crash test has become the bane of many auto engineers' existence. It's a particularly steep design challenge because it forces just 25 percent of a vehicle's front end to take the brunt of a 40-mile-per-hour impact. The newly released results of four family-minded minivans underscore just how difficult the crash test is: only one scored an Acceptable rating, and the other three did very poorly. The 2008-2015 Chrysler Town & Country and Dodge Grand Caravan, plus the 2011-2015 Nissan Quest, all received Poor ratings in the test, the IIHS' lowest possible score. The three of them showed significant crash intrusion into the driver's area. The dummy in the Nissan actually had to be cut out of the vehicle, with an IIHS spokesperson remarking, "the structure collapsed like a house of cards." In the Fiat Chrysler Automobile vans, the steering wheels moved out of the way, making the airbag less effective and letting the driver's head hit the dashboard. While it was not actually crashed, the agency is also giving the 2009-12 Volkswagen Routan a Poor score because it shares a structure with the FCA models. The newly released results of four minivans underscore just how difficult the small-offset crash test is. The refreshed 2015 Toyota Sienna (shown), conversely, earned an Acceptable rating and is also a Top Safety Pick+ because of its optional forward collision warning and automatic braking system. While the crash test dummy moved around during the impact more than the agency would have liked, sensors showed a low risk of injuries. The IIHS tested the Honda Odyssey last year, and it earned a Good overall score, the agency's best ranking. It's also a Top Safety Pick+ vehicle. The only member of the minivan segment left to test is the latest Kia Sedona, and the Institute is reportedly waiting a little longer for Kia to make changes to improve the model's performance. When reached for comment, Nissan spokesperson Steve Yaeger provided Autoblog with the following statement: "Nissan is committed to vehicle safety and believes that consumers should have information about crash protection so they can make educated buying decisions. Nissan is proud of the 2014 Quest's "good" rating in the IIHS front moderate overlap and side impact tests as well as a "good" head restraint rating.
