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.

Toyota shows a smoother autonomous Lexus for CES

Toyota is bringing a new research vehicle to CES. The TRI-P4 autonomous driving test vehicle, based on the Lexus LS500h, is a major step ahead, according to Toyota, as it has improved computing power and additional cameras for better reaction times. Earlier test mules have also used the LS as a basis, and the shift to the new, fifth generation LS brings chassis and steering-control benefits, so the vehicle's movements are smoother in automated mode. The camera tech has also been better integrated into the vehicle design, courtesy of CALTY in Ann Arbor, Michigan. Development has been swift, as the TRI's P2.1 car was unveiled in 2017. The P4 car will be used for Toyota Research Institute's Guardian and Chauffeur mode development. The two tiers differ somewhat, as TRI's Ryan Eustice explains: "Our Chauffeur development is focused on full autonomy, where the human is essentially removed from the driving equation, either completely in all environments, or within a restricted driving domain. Guardian, on the other hand, is being designed to amplify human performance behind the wheel, not replace it. The introduction of the new P4 platform will help us accelerate the development of both tracks when it joins our fleet this spring." The vehicle's situational awareness is boosted by two extra cameras facing on the sides, and a new imaging sensor both forward and rearward. Toyota says the P4's lidar setup is a carryover from the previous platform, but that its machine learning is much improved by its more powerful computer setup. The electricity required by the P4's computing power also comes from the hybrid battery, and as the computer "brain" is now housed vertically against the rear seat's backing, actual trunk space has been freed. More LS500hs will begin to be modified into TRI-P4 vehicles during spring 2019. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Couple survives 50-foot fall from overpass in Toyota

It doesn't matter the make or model - modern vehicles are technological miracles when it comes to occupant protection. Take this story out of New York City, which involved two people going for a very wild ride in a Toyota Matrix.
Carlos and Raquel Broadbelt were on the Cross Bronx Expressway overpass when they hit a patch of ice while dodging a pothole, sending them hurtling into a guardrail and over the side of the overpass. They fell 50 feet onto the road below. Despite the catastrophic accident - and the mangled Toyota - both driver and passenger walked away. The couple spent a night in the hospital just for observation.
The Broadbelts' miraculous survival has even surprised doctors, who told Dave Carlin from CBS New York they'd never seen an accident like it. Take a look below for the full news report from CBS New York.
