Aging Prius, dropping gas prices putting hurt on hybrid, EV sales

"As Prius represents by far the biggest chunk of the hybrid marketplace, where Prius goes, the segment goes," - Ed Kim, Autopacific
Fuel prices in the US have been tumbling for the last several weeks, with the average price of a gallon of gas at $3.120 as of October 20, according to the US Energy Information Administration. That price reflects a serious recent drop from $3.299 on October 6. Reports have even suggested that those low numbers might not change for a little while, perhaps as long as years. While drivers certainly love paying less at the pump, the change may be hurting the market for more fuel-efficient models, including the Toyota Prius.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.

Expedition drives from Russia to Canada over North Pole...

No, a Ford Expedition did not drive from Russia to Canada via the North Pole, but that's exactly what a team of intrepid explorers accomplished recently. Using specially-modified buses with massive tires, the group slowly drove 2,485 miles in 70 days over drifting ice, occasionally using a pickaxe to clear a path and staying on guard for chasms that could open up and plunge the team into the frigid arctic waters. Average speeds were about 6 mph, "at the speed of a (farm) tractor." While the big tires technically allowed the buses to float if the need arose, the team preferred to stay out of the water to keep the suspension from getting coated in thick, hard ice. Falling in on foot would mean almost certain death.
According to Phys.org, the buses were powered by Toyota diesel engines, but were built with prototype parts from a previous driving expedition to the North Pole. Right now, the machines are parked in a garage in Canada's Resolute Bay while the the team rests up with family back home. They plan to continue their trek to back across the Bering Straight to Russia. If successful, the team may eventually offer a version of their buses for commercial sale.
