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's Bob Carter says far fewer stations needed in shift from gas to hydrogen

Toyota's Bob Carter has been talking about green cars for years, but it's only been recently that his comments have really caught widespread attention thanks to his disparaging remarks about electric vehicle supporters like Elon Musk and Carlos Ghosn and optimism about hydrogen. Speaking at the opening of the Chicago Auto Show this morning, Carter said that Toyota has claimed the "pole position on CAFE," thanks to its deep hybrid bench. The company's green car cred will continue to grow because of its upcoming hydrogen fuel cell car, due out next year. Carter is relentlessly optimistic: "I truly believe fuel cells will fundamentally change how we feel about transportation," he said. The reason, Carter said, is that a hydrogen infrastructure will be easier to install than people think. He referenced a study conducted by the University of California (which we've heard about before) that found that California would only need 68 hydrogen stations to refuel the roughly 10,000 H2 vehicles that Toyota hopes to sell in by 2016 or so. That's a lot more than the nine that exist today, but the state has already approved funding for 20 new stations by 2015 and then up to 100 by 2024. Then he said this: "If every vehicle in California ran on hydrogen, we could meet refueling logistics with only 15 percent of the nearly 10,000 gasoline stations currently operating in the state." "We could meet refueling logistics with only 15 percent of gasoline stations currently operating in CA" - Bob Carter This made us wonder: if the refueling time and range are roughly equivalent between hydrogen and gasoline – Toyota's hydrogen car is supposed to be able to go 300 miles on a five-minute fill-up - then why has the market decided that there should be 10,000 gas stations in California and why would 1,500 be sufficient for hydrogen? "If the locations are optimized," he said, "we don't need 10,000 stations." For example, at major intersections, instead of three gas stations, you'd really just need a single hydrogen one. "There are a lot of questions about the infrastructure, but it's coming. ... It's a hurdle that we've got to climb but it's not as steep as some may imagine." Toyota's Mike Michaels, the national manager, media and public affairs at Toyota Motor Sales, then stepped in to point out that there are gas stations closing and admitted that there might be too many gas stations in California.

Hyundai Prius-fighting hybrid spied wearing new camo

Hyundai's engineers certainly don't want the public to see its upcoming dedicated hybrid model in several of these new spy shots, but the company can't deny that the machine is on the way. These test cars were first spotted last summer as Prius-like five-door hatchbacks. However in these photos and the second set, it would seem that the model has morphed into a more sedan-like shape similar to the Chevy Volt. Unlike the last time we saw this car during arctic testing, the vehicle no longer is covered in plastic concealment. That obfuscation has been replaced with a very effective camo pattern on everything but the roof, and in several photos, workers are actively standing in the way of the spy shooters' lenses. Beyond the whole model's general shape, there are a few details to pick out, though. You can easily spot the outline of the brand's hexagonal grille up front. There appears to be a rather complicated air dam design there, too. In profile, the shape of the rear hatch creates an integrated spoiler at the back. While the camouflage makes it very hard to tell, we don't see a plug-in port on this example. According to our spies, this test car was being driven with a slew of other electrified models, including a BMW i3, Nissan Leaf, Volkswagen e-Golf, and Kia Soul EV. Given that group, perhaps the engineers were specifically benchmarking the electric performance for this outing. Earlier reports suggest that Hyundai's latest hybrid could debut in the second half of 2016. Power reportedly comes from a 1.6-liter four-cylinder with hybrid assistance and a lithium-ion battery. Plug-in and five-door hatchback versions are also rumored.
