New Toyota Mirai videos continue questionable hydrogen claims

"Toyota engineers were simultaneously working on a brand new technology that met all the driver's needs with an even smaller carbon footprint." Toyota has released a number of new promotional videos for the hydrogen-powered 2016 Mirai. Most are exactly what you'd expect: pretty, full of promise and vaguely informational. But there was one line in the Product Introduction video that caught out ear. In the Product Information video about the Mirai, the narrator goes into a short history of Toyota's green car advances. After talking about the Prius and the Prius Plug In, making EVs for urban commuting and the rest of Toyota's advanced fuel programs, we hear this: "Never satisfied though, Toyota engineers were simultaneously working on a brand new technology that met all the driver's needs with an even smaller carbon footprint, one that took its lead from nature itself." You can watch the video (and four others) below. Plug In America co-founder Paul Scott told AutoblogGreen, "Show us the math! Toyota claims the FCV has a smaller carbon footprint than their EV, but every paper I've read indicates the FCV uses 3-4 times as much energy to travel a given distance as an EV. If they are making this claim, let's call them out to prove it. Show us the math!" There's some math that comes out in favor of EVs here and here. "BEVs and FCs have a very similar carbon footprint, dependent on fuel source." – Toyota's Jana Hartline Plug-in vehicle advocate Chelsea Sexton went further. "Assuming appropriate comparisons in energy feedstock, basic science doesn't support the notion that the footprint of an FCV is smaller than that of an EV," she told AutoblogGreen, explaining that "appropriate comparison" would mean using similar energy generation methods for both hydrogen and plug-in vehicles. Not the tendency, she noted, "of H2 fans to compare FCVs based on solar-based electrolysis to EVs running on coal-bases electricity and similar shenanigans." Besides, Sexton said, "focusing purely on efficiencies entirely misses the biggest struggles that FCVs face in the market, namely fuel price, inconvenience, and market fear, even if the vehicles themselves are initially subsidized.

Recharge Wrap-up: Toyota FCV ready for production, Nissan tests Leaf-to-Home energy management

Toyota will begin selling its hydrogen fuel cell vehicle (FCV) in Japan in December. The US and Europe can expect to see the car become available next summer. The FCV, which will likely be called "Mirai" (meaning "future") in Japan, is ready for production ahead of its initial deadline at the end of the fiscal year in March. Toyota planned for annual production of 700 units, but might increase output to meet higher-than-expected demand, which is currently nearing 1,000 units. The cars will mostly be sold in the four cities where a hydrogen fueling infrastructure is already being put in place: Tokyo, Nagoya, Osaka and Fukuoka. Read more at Nikkei Asian Review. Nissan is testing the Leaf EV as part of an energy management system including "Leaf to Home" technology. The system allows the Leaf to help support the power grid during peak energy usage, or provide backup power to a home or building during outages, particularly in emergencies like natural disasters. Using the Leaf's battery to provide electricity during peak hours would lessen the demand on the grid and make the system work more efficiently. Furthermore, if consumers are compensated for the energy saved by using the Leaf for power during periods of high demand, it could encourage more people to adopt the EV.

CDP keeps track of how much companies are disclosing about their impact on global climate change. "The need for data on corporate climate change impacts and strategies to reduce them has never been greater," says CDP CEO Paul Simpson. "For this reason we congratulate those businesses that have achieved a position on CDP's Climate Disclosure Leadership Index." Other perfect scores were earned by Nissan, BMW, Daimler and General Motors. Read more in the press release from Honda below. Scientists at Stanford University have developed a lithium ion battery that can warn users before it overheats. A thin layer of copper between the anode and the layer separating the anode from the cathode acts as a sensor. When it detects lithium buildups from overcharging are approaching the separator, it sends an early alert long before it gets to a point where it would cause a short (which could lead to a fire). The new safety measure could be used in all sorts of battery applications, and not be limited to EVs. Learn more at Phys.org.

2018 Nissan Kicks vs other tiny crossovers: How they compare on paper

Update: As we now have now driven the 2018 Nissan Kicks and have all the specs and figures available, we thought it was time to update this comparison post. The data chart has been updated with final Kicks information as well as changes to competitors made for 2019. Anyone else have "Pumped Up Kicks" by Foster the People stuck in their heads? Well, you do now. I couldn't be the only one. Anyway, the 2018 Nissan Kicks is a thing. It replaces the Nissan Juke, which Mr. Stocksdale thought was a bad idea and Mr. Myself thought was a smart idea. Nevertheless, neither of us were especially pumped up by the Kicks. However, the majority of car buyers are all about SUVs, and this littlest segment of them has been multiplying like Tribbles in the past few years. The Juke was one of the first of these subcompact crossovers, but it was probably too oddball for a mainstream audience (not to mention inefficient) and never really caught on. Newer competitors certainly didn't help. Well, to see how the Kicks compares to those very competitors, lets fire up the Autoblog Comparo Generator 3000 (TM). Specifically, we'll be looking at those subcompact crossovers with similarly small dimensions, especially low prices and/or a disinclination to offering all-wheel drive. We're talking about the Nissan Kicks vs the Toyota C-HR, Hyundai Kona, Kia Soul, Honda HR-V and Jeep Renegade. Now, if you're interested in literally the exact opposite SUV segment, check out our recent Mercedes G-Class comparo. Otherwise, on to the spreadsheet: Dimensions and passenger space In terms of exterior dimensions, the new Kicks is right smack in the middle of the segment. It's virtually the same as the Honda HR-V, yet manages to eek out a few extra cubic feet of cargo space behind its raised back seat. The Honda and its "Magic Seat" still beats it in terms of maximum capacity, but it sure is close. The Kia Soul has the biggest maximum number, but that's largely the result of being a box. Its small behind-the-back-seat cargo number is likely a better indicator of how much you'll be dealing with on a day-to-day basis. And in that day-to-day way, the Kicks is excellent. Backseat legroom seems to be a Kicks downside, as all but the C-HR surpass it. (Seriously, it's almost impressive how large the C-HR is on the outside but cramped inside.) However, the Kicks' tall greenhouse not only allows for ample headroom, but seats that are mounted high off the ground.
