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.

Toyota promoting Mirai as if hydrogen tax credit never went away

At the end of December, the US federal government let the $8,000 tax credit for hydrogen-powered vehicles expire. Despite this little wrinkle, Toyota is still promoting the upcoming 2016 Mirai fuel cell vehicle as a car that will cost under $50,000. In some cases a lot less, since it may also qualify for a $5,000 incentive in California. The car has a $57,500 MSRP, but Nihar Patel, vice president of North American Business Strategy for Toyota Motor Sales, spoke at the 2015 Washington Auto Show last week, and said that the Mirai could cost $44,500 in California. You can see this in the video at around minute four. Toyota knows that the federal incentives have expired, since the real news from the show was Patel's public request to the federal government that the $8,000 tax credit be extended. "We think that the federal credit expiration last year puts [hydrogen] customers in a fairly disadvantageous postion," he said. Plug-in vehicle buyers can still get up to $7,500 tax credit and, "we believe that this inequity needs to be fixed," he said. You can see this in the video at minute 10:20. Toyota said including both the after-incentives price and the call to reinstate those incentives was intentional since it shows a discrepancy between hydrogen and plug-in vehicles in the eyes of the feds. We asked Toyota's director of Energy and Environmental Research, Technical and Regulatory Affairs, Robert Wimmer, for more details on Toyota's request. "[The Mirai] being a ZEV and battery electrics also being ZEVs, we just want to make the playing field as level as possible," he said, adding that any extension would last "for the run of the vehicle," which would be three years. He admitted that the extension might only be for one or two years, if it happens at all. (A Toyota spokesperson clarified to AutoblogGreen that the Mirai program will not end after three years.) And that's the problem. "The tax process is difficult to predict," he said. "The two challenges we have now are that both houses of Congress are Republican and also that there has been talk for a while about comprehensive tax reform. If that moves forward, then extenders would probably be put on the back burner as comprehensive tax reform is discussed." Wimmer would not reveal any details about how Toyota is pressuring the government to act, only saying that Toyota's has people lobbying up on Capitol Hill.

IIHS: Drivers safer than passengers in frontal crash test

The Insurance Institute for Highway Safety introduced a small overlap frontal crash test in 2012 that replicates what happens when the front corner of a car impacts another object. In the test, vehicles travel at a speed of 40 mph toward a five-foot-tall barrier with 25 percent of the total width of the car striking the barrier on the driver side. One would assume that vehicles with good small overlap front ratings would protect the driver and the passenger equally. But a recent study from the IIHS proves that passengers aren't as protected as drivers. The IIHS conducted the test on seven small SUVs with good driver-side small overlap ratings and only one of the vehicles, the 2016 Hyundai Tucson, performed well enough to be given a good rating. The other SUVs performance ranged from poor to acceptable. After reviewing the results of the test, the IIHS is deliberating whether it should institute a passenger-side rating as part of its Top Safety Pick criteria. "This is an important aspect of occupant protection that needs more attention," states Becky Mueller, lead author of the study and an IIHS senior research engineer. "More than 1,600 right-front passengers died in frontal crashes in 2014." Since the small overlap front test was introduced, 13 automakers have made structural changes to 97 vehicles with roughly three-quarters earning a good rating after the adjustments. The IIHS' test for frontal ratings is completed with a dummy in the driver's seat and with a barrier overlapping the driver's side. Which makes sense, as passengers aren't always riding in a vehicle. "It's not surprising that automakers would focus their initial efforts to improve small overlap protection on the side of the vehicle that we conduct the tests on," states David Zuby, IIHS executive vice president and chief research officer. "In fact, we encouraged them to do that in the short term if it mean they could quickly make driver-side improvements to more vehicles. As time goes by, though, we would hope they ensure similar levels of protection on both sides." As the IIHS' test revealed, there's a massive difference in safety between the two front seats. Increase passenger safety, according to Mueller, would require automakers to strengthen the occupant compartment by using a different type of material or by making it thicker.
