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.

Mitsubishi and Nissan teaming up on electric kei car

Nissan and Mitsubishi have announced plans to build an electric kei car together. The yet-unnamed car would mark a major step towards electrification of Japan's popular supercompact segment. The car will be powered by a 20 kWh battery and will be engineered to cover daily driving duties in a Japanese driving cycle. The car can also double as a mobile power source or power a home in emergency situations. Nissan says the car will measure 134 inches long, 58 inches wide, and 65 inches tall, in order to comply with laws limiting kei car size. The companies state that the car will be developed by NMKV Co., Ltd., a joint-venture that stands for Nissan Mitsubishi Kei Vehicle. Each carmaker owns a 50 percent stake, and already jointly builds models such as the feline favorite Nissan Dayz, which Mitsubishi sells as the eK. In reality, that likely means Mitsubishi will be developing the car and Nissan will simply slap a badge on it. Nissan has not traditionally built kei cars, choosing instead to rebadge those made by Suzuki or Mitsubishi. In fact, Mitsubishi built the first electric kei car, the i-Miev, way back in 2009, and it was actually sold in the U.S. until 2017. The jellybean-shaped EV was a pioneer in the field, but its 62-mile range from a 16 kWh lithium-ion battery showed the limitations of the technology at the time. Mitsubishi moved about 32,000 of them before they pulled the plug, with a pre-tax-credit price ranging from $23,000 to $31,000. The new Nissan-Mitsubishi kei car will land at around 2 million yen, or $18,200. The price, while slightly more expensive than a gasoline counterpart, bucks predictions from analysts that said prices would skyrocket by 66 to 120 percent if kei cars were forced to electrify. A petrol-powered Nissan Dayz starts at around $15,200. Size-wise, the two share a similar footprint as they are governed by kei car size limits. The special class of cars get unique license plates and other registration cost benefits due to their compact dimensions. A BMW i3 would exceed those boundaries due to its 158-inch length and 70-inch width. However, the larger EV comes equipped with a substantially bigger 42.2 kWh battery good for 152 miles of range. Though no photos have been released, we predict it will look like the iMk concept (pictured above). The car will go on sale in spring 2022. Related Video This content is hosted by a third party.

Chevy Volt, Nissan Leaf go nearly the same all-electric miles a year

Range anxiety? What range anxiety? The concept is a foreign one to those driving Chevrolet Volt extended-range plug-ins, and as a result, that vehicle's all-electric driving miles are actually pretty close to that of the all-electric Nissan Leaf. Such were the findings of a study conducted by the Idaho National Laboratory (INL), which tracked about 8,700 cars during a three-year period, including a bunch of Volts, Leafs and Smart ED electric vehicles. In short, even though the Volt's all-electric range of about 38 miles is less than half that of the Leaf's, the Volts' collective all-electric driving was just six percent lower than the Leaf's (the next-generation Volt will be even more electro-generous, with a 50-mile range). The logic makes sense considering typical US driving habits, in which a vast majority of people commute less than 35 miles a day. Additionally, Volt drivers obviously have no fear of running out of electricity, so they were far more likely to max out on that range than some Leaf drivers. Overall, the average Leaf is driven about 15 percent less than the national average of about 11,300 miles a year for all vehicles, while Volts are driven about eight percent more. Of all those Volt miles, about 81 percent were in all-electric mode. Additionally, Volt drivers recharged about 1.5 times a day, while Leaf drivers recharged about once a day, and about 85 percent of that charging was at home. As for non-home charging, about 20 percent of the vehicles accounted for 75 percent of the station use, so folks are definitely creatures of habit.
