Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.

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.

US Congress lets $8,000 hydrogen vehicle tax credit expire

When Toyota introduced the 2016 Mirai last month in preparation for a launch late next year, it said that the hydrogen car will have a $57,500 MSRP and that there will be a federal tax credit available worth up to $8,000. The problem, as we noted at the time, is that that federal credit was set to expire at the end of 2014. The technical language of the current rule says that someone who buys a fuel cell vehicle, "may claim a credit for the certified amount for a fuel cell vehicle if it is placed in service by the taxpayer after Dec. 31, 2005, and is purchased on or before Dec. 31, 2014." With the 113th Congress now finished up for the year and legislators headed home for the holidays, we know one thing for certain: the federal tax credit for hydrogen vehicles was not updated and will end as we're all singing Auld Lang Syne next week. All of this isn't to say that Mirai buyers won't be able to take $8,000 off the price of the car 12 months from now. For proof of that, we only need to look at other alternative fuel tax incentives and realize that this Congress simply isn't moving fast enough to deal with things that are expiring right now. One of the last things that the 113th Congress did in December was to take up the tax credits that expired at the end of 2013 and renew some of them. Jay Friedland, Plug In America's senior policy advisor, told AutoblogGreen that PIA and other likeminded organizations worked with Congress to extended the electronic vehicle charging station (technically: EVSE) tax credit that was part of the Alternative Refueling Tax Credit in IRS Section 30(C) through the end of 2014. "Individuals can deduct 30 percent of the cost of purchasing and installing an EVSE up to $1,000; businesses, 30 percent up to $30,000," he said. "This tax credit is applied to any system placed into service by 12/31/14 and is retroactive to the beginning of the year. So go out and buy your favorite EV driver an EVSE for the holidays," he said. An electric motorcycle credit was killed at the last minute as Congress was getting ready to leave, but H.R. 5771 did extend the Alternative Fuels Excise Tax Credits for liquefied hydrogen and other alternative fuels. These sorts of tax credit battles happen all year long. In July, Blumenthal introduced the Fuel Cell and Hydrogen Infrastructure Act of 2014, which never got out of the Finance Committee.
