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 NV400 becomes Japan's first electric ambulance

Consumer passenger cars aren't the only vehicles undergoing electric transformations. We've seen the introduction of early electric fire trucks, and now Japan is getting its first electric ambulance. It's a Nissan NV400, and it will be used by the Tokyo Fire Department at the Ikebukuro station. Though badged as a Nissan, the NV400 is at its heart a Renault Master Z.E. electric van. The powertrain is the same as the French van with a 33-kilowatt-hour battery (7 kWhs less than the base Nissan Leaf) and a 55-kW motor driving the front wheels. That translates to 74 horsepower and 162 pound-feet of torque. That doesn't sound like much, but in as dense a city as Tokyo, it's not likely the NV400 will be able to reach high speeds at all, even if it had a Hellcat engine. There are a couple of unique additions to the van to enhance its ambulance capability. One is the inclusion of a separate 8-kWh lithium-ion battery that can operate all the equipment on board for long periods of time without eating into the ambulance's range. It can even be used like a generator to provide power to external emergency equipment. Then there's the stretcher, which Nissan vaguely says is electrified to make it easier to use by the medical personnel. We presume the stretcher has an electric motor to make it easier to push around. Since neither the NV400 nor its Renault counterpart is sold here, we're not expecting to see one of these ambulances in the U.S. any time soon. But electric versions of local emergency vehicles seem like a good idea, since range wouldn't be an issue, and the torque would be useful in large vehicles. Ford is readying an electric full-size Transit, which is offered in America in gas versions. Perhaps we could see some electric Ford ambulances in the near future. Related Video:

Nissan beats 2Q expectations with $1.3b profit

Nissan reported its Q1 financial results through the April-June period, and Bloomberg reports that the Japanese automaker beat analyst expectations. The outlet averaged income estimates provided by 11 analysts to come up with a figure of 130.2 billion yen ($1.3 billion), while Reuters' analyst survey returned a estimate of 163 billion yen ($1.6 billion) in operating profit. Nissan easily beat them both with 152.8 billion in net income and 193.7 billion in operating profit. That profit number is up from 122.6 billion yen in the same quarter last year. The surge comes from increased US sales. June sales grew 13 percent, helping propel a 4.5-percent increase for the year so far and the best first-half calendar-year sales Nissan has had in ten years. Higher incentives have helped, as well as superheated Nissan Rogue sales; the crossover moved 99,302 units through the first six months of 2014, this year that number is 135,397, and observers expect its popularity to continue. In contrast to other automakers struggling with the slowdown in China, Nissan isn't doing so badly there. Growth rose by 5.7 percent in the first half of this year, a number that would have been larger but for depressed commercial vehicle sales because of the economy's slowdown. Nissan is sticking with its original targets, sure that government intervention and new models will hold the markets steady enough. The press release below has more information on the numbers.
