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.

Hyundai, Kia, Genesis and Subaru clean up in IIHS 2018 safety ratings

Hyundai, its partner Kia and its Genesis division are the big winners in the latest vehicle safety ratings from the Insurance Institute for Highway Safety, accounting for six of the 15 models that earned the Top Safety Pick+ awards for 2018. Subaru was right behind with four, Mercedes-Benz had two, and Toyota, BMW and Ford each had one. Another 47 vehicles earned the Top Safety Pick designation, where Toyota had 10 vehicle models, with Hyundai recognized for nine models. All but one of the seven vehicles in Subaru's lineup, the BRZ, qualified for one of the awards. IIHS strengthened the criteria for the Top Safety Pick+ award for 2018 to require headlights to earn a "good" rating — an "acceptable" rating was previously enough to notch the "plus" award — and good or acceptable passenger-side protection in the small overlap front crash, which replicates a crash involving just the front corner of a vehicle. It also required vehicles to have acceptable or good headlights for the first time to earn a Top Safety Pick award. Most of winners for both awards qualified on the basis of optional upgrades. IIHS in October began evaluating the passenger side of vehicles in its small overlap front crash test after it said it became clear that automakers were neglecting that side of the vehicle as they focused on improving driver-side protections. IIHS first began conducting driver-side small overlap crashes in 2012. It began measuring both how well low and high beams illuminated the road and the amount of glare they produce for oncoming vehicles as part of its ratings in 2016. The Top Safety Pick+ winners are listed below. The list doesn't include any minivans, pickups or minicars, which don't appear on either list of awardees.
