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.

Rod Millen to face Monster Tajima in Electric Division of Pikes Peak Hill Climb

The 91st running of the Pike's Peak International Hill Climb is scheduled to begin on June 30. Like last year's event, the 12.42 mile course - fully paved these days - starts at 9,390 feet elevation and doesn't stop climbing until it reaches an impressive 14,110 feet (the air is so thin up there that the FAA requires pilots to use oxygen at that altitude).
There will be an assortment of internal combustion machines racing to the summit, entries from France, Italy, Japan, Latvia, Sweden, Brazil, Canada, Great Britain, Hungary, Czech Republic, Poland and Belgium, but all eyes will be on the electric showdown between Rod Millen and Nobuhiro "Monster" Tajima, from Japan. 61-year-old Millen is a familiar name to Toyota racing fans, and he will be driving the Toyota TMG EV P002 (it won the Electric title last year), while Tajima will be again piloting the Monster Sport E-Runner (which was forced out of the field last year after a fire broke out).
Other entrants include Rhys Millen driving a 2013 Hyundai PM58OT and Paul Dallenbach, who will be driving Millen's Hyundai Genesis Coupe (it set the all-time speed mark last year).

Ford only automaker to make 2012 Buzz Rankings, Toyota most improved

Ford landed itself a spot among the top 10 brands in the 2012 Buzz Rankings. The annual index scores 1,100 brands in 41 categories to determine which nameplates had the most positive buzz throughout the year.
For the third year in a row, Subway took the top honors overall with a score of 40.3, and Ford was the only automaker to break into the top 25 by earning a sixth-place finish overall. The manufacturer earned a score of 32.1 points, which was enough to push it up one spot from the 2011 Buzz Rankings. Honda managed 21.2 points overall, which is still well behind 25th-place Kohl's at 26.5 points. Toyota, Volkswagen and BMW all round out the top five automakers.
The 2012 Buzz Rankings also keep track of which brands improved the most over the past year, and this year, Toyota was the manufacturer with the largest leap forward. The Japanese automaker jumped from just 14 points in 2011 to 20.5 in 2012. Chrysler, Kia, Dodge and Volkswagen all saw sizable steps forward as well.
