Is 120 miles just about perfect for EV range?

When it comes to battery-electric vehicles, our friend Brad Berman over at Plug In Cars says 40 miles makes all the difference in the world. That's the approximate difference in single-charge range between the battery-electric version of the Toyota RAV4 and the Nissan Leaf. It's also the difference between the appearance or disappearance of range anxiety. The 50-percent battery increase has zapped any lingering range anxiety, Berman writes. The RAV4 EV possesses a 40-kilowatt-hour pack, compared to the 24-kWh pack in the Leaf. After factoring in differences in size, weight and other issues, that means the compact SUV gets about 120 miles on a single charge in realistic driving conditions, compared to about 80 miles in the Leaf. "The 50 percent increase in battery size from Leaf to RAV has zapped any lingering range anxiety," Berman writes. His observations further feed the notion that drivers need substantial backup juice in order to feel comfortable driving EVs. Late last year, the Union of Concerned Scientists (UCS), along with the Consumers Union estimated that about 42 percent of US households could drive plug-in vehicles with "little or no change" in their driving habits, and that almost 70 percent of US commuters drive fewer than 60 miles per weekday. That would imply that a substantial swath of the country should be comfortable using a car like the Leaf as their daily driver - with first-quarter Leaf sales jumping 46 percent from a year before, more Americans certainly are. Still, the implication here is that EV sales will continue to be on the margins until an automaker steps up battery capabilities to 120 or so miles while keeping the price in the $30,000 range. Think that's a reasonable goal to shoot for?

BMW i5 returns as next rumored i Project vehicle

Hydrogen fuel-cell vehicle enthusiasts may want to give each other some high-fives when they hear the latest news about BMW's reputed i5. The German automaker has been rumored to be on the verge of expanding its i brand beyond its i3 battery-electric and i8 plug-in hybrid cars for a long while. The latest rumors say that BMW could be working on a hydrogen-powered i5 crossover. BMW is in the "final stages of consideration" of expanding the sub-brand, Bloomberg News says, citing comments BMW executive Ian Robertson made this week at the Frankfurt Motor Show. There may be more light-weighting efforts, and an alternative powertrain is sure to be in order, but there are few details beyond that. BMW of North America spokeswoman Rebecca Kiehne declined to comment to AutoblogGreen. Since 2013, BMW has worked with Toyota on hydrogen fuel-cell drivetrains and might further expand that relationship, MarketWatch says, citing BMW financial chief Friedrich Eichiner. The two automakers have already worked together on a prototype BMW 5 Series sedan with a hydrogen-powered engine. That car was unveiled this summer. Earlier this year, we heard reports about an i5 that would actually be a hybrid-electric vehicle of sorts, and an extremely powerful one. That rumored vehicle – again some sort of modified 5 Series – would actually contain one gas-powered engine and two electric motors, all combining for more than 540 horsepower. If these latest rumors turn out to be true, they would mark a change in things, but we won't be surprise if we hear yet another version of what the i5 will be before it's all said and done.

The real reason automakers are giving away free hydrogen

Just like Hyundai did with its Tucson fuel cell, Toyota is offering free hydrogen fuel with the $57,500 Mirai H2 sedan. Toyota is being a bit vague about the details, saying simply that Mirai drivers will get, "complimentary hydrogen fuel for up to three years." Turns out, the reason that the hydrogen avant-garde will not be paying anything at the pump isn't because the automakers want to give them a boost or because the OEMs are kind. Instead, it's simply impossible to accurately charge people for hydrogen right now. It's simply impossible to accurately charge people for hydrogen right now. At an in-depth hydrogen seminar this week as part of the Mirai preview, three representatives from various hydrogen organizations revealed that the current hydrogen stations (most of which are in California) are not set up to accurately measure the hydrogen that is dispensed. Without this little bit of information, you can't charge customers for the fuel they use. Toyota is well aware of this, and Toyota Motor Sales' national manager of environmental, safety and quality communications, John Hanson, said that, "There are no set standards, so there is no way to charge people for anything." Alberto Ayala, the deputy executive officer for the California Air Resources Board, said CARB is in the middle of developing a way to sell a given amount of hydrogen, "which up to this point doesn't exist. If you think about it, it's a real simple yet real practical challenge. If you're going to pay for X amount of hydrogen, you're actually getting that amount of hydrogen." Ayala said it's not a difficult technical problem to measure the hydrogen as it goes into the car, but "we just have not done it. We are at a point where we are solving multiple remaining questions [with hydrogen infrastructure], and that just happens to be one of them." The National Institute of Standards and Technology says that there has been a discussion to change the current tolerance of two percent up to 10 or 20 percent, but that new technology should be able to measure accurately to within one percent. Air Liquide is working with Toyota to launch the Mirai in the US and Air Liquide CEO Ole Hofelmann told AutoblogGreen that being able to charge customers will be key to the technology's success. "We need to make sure we accurately measure the gas," he said.
