Japan's government gives hydrogen vehicles a big boost

The Japanese government is really paving the way for hydrogen fuel cell technology on its roads. Japan's Ministry of Economy, Trade, and Industry is changing regulations on fuel tanks to make hydrogen cars more appealing to drivers, which should help put the country ahead of others in the race to develop a viable H2 fleet. Japan is raising the allowed pressure of hydrogen tanks from 700 atmospheres to 875, which has the effect of increasing driving range by 20 percent. This move puts the country in line with others with high-pressure fueling regulations. Japan is also in talks with the United Nations and the European Union to streamline inspection rules to make it easier to export Japan's fuel-cell vehicles. Toyota premiered its hydrogen-powered FCV Concept at the Tokyo Motor Show last year and plans to release a production version as early as next year. Honda also plans to build its own fuel-cell cars for 2015, and it debuted its FCEV Concept at last year's Los Angeles Auto Show. Nissan is sending mixed messages on hydrogen, both questioning the availability of a refueling infrastructure and working on developing the vehicles. In Japan, a relatively small country, increasing the range of fuel-cell vehicles makes creating a usable infrastructure a bit less daunting. Will hydrogen-fueled electric cars see the same sort of success as Toyota's Prius hybrid or battery-powered EVs? Only time will tell, but we can keep our fingers crossed that it will, and that the popularity spills over beyond Asia.

Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

Toyota, Honda, Mazda and Nissan recall 3.4 million vehicles for faulty airbags

Most vehicle recalls that take place these days are a result of some problem that happens during the manufacturing process by the automaker, but as we see here, parts suppliers can also factor in to problematic safety issues. Automotive News is reporting that a total of 3.4 million vehicles produced by Japanese automakers between 2000 and 2004 are being recalled globally due to faulty airbags produced by an outside supplier, Takata Corp.
According to the report, vehicles from Toyota, Honda, Nissan and Mazda are being recalled because of passenger front airbags that do not inflate properly. Globally, Toyota is said to be recalling around 1.73 million cars including 510,000 in the US composed of Toyota Corolla, Matrix, Sequoia and Tundra as well as the Lexus SC430 for the 2001 through 2003 model years; this is the second time this year the 2003 Corolla and Matrix have been recalled for an airbag problem. Honda is recalling 1.14 million models, Nissan another 480,000 and Mazda 45,463. The article says that Takata supplied faulty airbags to non-Japanese automakers, but it did not specify which ones.
Honda and Toyota have released information on their own websites about the recall, while Nissan and Mazda have not yet commented. Read official press releases from Honda and Toyota, below, and look for updates as we have word from the others.
