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 throwing water on fast-charging EVs

Toyota is undoubtedly committed to moving beyond the internal combustion engine for future automobiles. But, while the company embraces hybrids with boosted production, new models and in motorsports, the automaker is more standoffish when it comes to pure electric models. This is especially true as the Mirai hydrogen fuel cell sedan comes to market. In the mind of Mirai chief engineer Yoshikazu Tanaka, even fast-charging electric vehicles don't have much of a future because of their strain on the power grid. "If you were to charge a car in 12 minutes for a range of 500 km (310 miles), for example, you're probably using up electricity required to power 1,000 houses," he said to Reuters. Tanaka admitted that EVs have a place in the market, but it was for short drives during the day after being charged each night. As one of the people responsible for bringing the Mirai to the road, it shouldn't be too shocking that Tanaka puts his faith in hydrogen. He feels that H2 is the better choice for long-distance driving because of the available range and speed of refueling. "Of course, there are technological hurdles that need to be cleared to make this commercially viable," he said to Reuters. One of the biggest of those obstacles is building a new refueling infrastructure. But, despite government subsidies, Japan looks set to miss its goal of opening 100 H2 stations by the end of March 2016. Toyota has thrown a lot of support behind hydrogen but has been accused of overstating some of the fuel's benefits and embellishing the current refueling infrastructure. Still, engineers at the automaker are working to bring the cost of the fuel cell vehicle down to the level of a diesel by 2022.

2013 Toyota RAV4 earns 'poor' rating in IIHS small overlap crash test [w/video]

When the Insurance Institute for Highway Safety tested a batch of SUVs in its small overlap frontal crash test earlier this year, it held off on putting the Toyota RAV4 in the blender because the new, 2013 model was due to arrive shortly after the test. The new crossover might be better than it was before, but it could still only manage a rating of "Poor" in the test that has been a bugbear for a number of manufacturers.
Among other issues, the IIHS noted that the steering column moved seven inches to the right causing the crash test dummy to practically miss the airbag, the dummy's left foot was trapped in deformed sheetmetal and the dummy's head hit the instrument panel.
The 2013 RAV4 earned the Top Safety Pick rating by scoring well in the Institute's four other tests. A good score in this particular test would have earned it the Top Safety Pick+ rating that is so far only claimed by the 2014 Subaru Forester and 2013 Mitsubishi Outlander Sport in the SUV category. There's a press release below with more details and a video of the test.
