China sticking to its guns on EVs for the future

Automakers are obviously free to develop whatever next-gen, zero-emissions tech that they want. However, if a company wants to get on the good side of the Chinese government, that strategy better include some plug-in vehicles. The authorities there are lending major support to plug-ins at the moment, and its forcing the auto industry to play along. According to Bloomberg, Toyota, Volkswagen, Hyundai, and BMW are all launching dedicated EV brands with their joint venture partners, and as many as 40 electric models could hit the Chinese market this year alone. However, analysts don't think the vehicles are going to sell well. Instead, the launches are essentially a way for companies to play nice with the government and help get the approval to build factories in the country. Take Toyota as an example. The company is pushing the future of hydrogen hard with promotional films for the Mirai and engineers talking down fast-charging EVs. Still, the Japanese automaker is getting ready to launch two EV brands in China with its joint venture partners, according to Bloomberg. China's push for alternative fuels has been happening for a while, but it really kicked into high gear last year. The government has set a goal to improve fleet-wide economy by 40 percent by the end of the decade in order to spend less importing oil and for the population's health. The plan has shown some success so far with hybrid and EV sales growing early in 2015.

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.

IIHS study finds minivans are unsafe for second-row passengers

The Insurance Institute for Highway Safety (IIHS) updated its moderate overlap front crash test in late 2022, and it found that four minivans struggle to protect second-row passengers. The agency stresses that minivan manufacturers need to prioritize safety for the rear occupants. While the minivan is no longer a common sight in driveways across America, it remains relatively popular among buyers with kids and gear to haul around. The IIHS tested four models: the Chrysler Pacifica, the Kia Carnival, the Toyota Sienna and the Honda Odyssey. These vans were put through an updated test that places a dummy the size of a small woman or a 12-year-old child in the seat directly behind the driver. IIHS explains that, for a vehicle to earn a "good" rating, there can't be an excessive risk of injury to the head, neck, chest or thigh. None of the four minivans achieved that distinction; the Pacifica, the Carnival and the Sienna got a "marginal" rating, while the Odyssey scored a "poor" rating. IIHS also points out that, with the exception of the Sienna, these vans lack a seatbelt reminder for the second-row passengers. Chrysler Pacifica View 5 Photos "The restraint systems in all four vehicles leave the second-row occupant vulnerable to chest injuries, either because of excessive belt forces or poor belt positioning. That's concerning because those injuries can be life-threatening," said Jessica Jermakian, the IIHS vice president of vehicle research, in a statement. IIHS stresses, in spite of these results, the back seat remains the safest place for children to travel in. In the Sienna, the rear dummy "submarined" (or slid forward) beneath the lap belt while the shoulder belt moved toward the neck. In the Carnival and the Pacifica, the seatbelt put too much force on the dummy's chest. IIHS adds that, alarmingly, the Pacifica's side curtain airbag did not deploy during the crash test and that the forces exerted on the dummy's neck were high in the Carnival. In the Odyssey, the forces exerted on the head and on the neck were even higher, and the dummy's head came too close to the front seatback in spite of the seatbelt. On a brighter note, all four vans earned a "good" rating for front-passenger protection. Related video: This content is hosted by a third party. To view it, please update your privacy preferences.
