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 plotting WRC-inspired Yaris hot hatch

The emergence of the new Honda Civic Type R goes to show that the Japanese can make hot hatches every bit as good as the Europeans. But though it's been a while since Toyota had a serious contender in the game, word has it that it's about to jump back in. The impetus for Toyota's (re-)entry into the hot hatch segment is its impending return to the World Rally Championship. The company announced just a couple of months ago its intention to run a Yaris-based (or at least -styled) rally machine in the WRC by 2017, and now the latest reports indicate a road-going version won't be too far behind. Though the competition-spec model is expected to pack a 1.6-liter turbo four built by Toyota Motorsport GmbH specifically to comply with FIA regulations, the street-legal Yaris hot hatch is tipped to carry the 2.0-liter turbo four from the Lexus NX 200t. Though the jury's still out, it'd likely stick with front-drive instead of a more complex all-wheel drive system, but with a six-speed manual and a limited slip differential, it has all the potential to be a real firecracker. Only a limited number will likely be offered, ostensibly to meet FIA homologation requirement – in the same vein as the Citroen DS3 Racing or the Volkswagen Polo WRC Street – and likely to carry a similarly premium price tag in the neighborhood of 34,000 euros. We'd be pleasantly surprised if any of them were to make it to North American showrooms, though.

Earthquake causes most of Toyota's Japan operations to shut down

Toyota is idling a large portion of its Japanese assembly plants as a result of the devastating earthquake in Hokkaido, Japan. The earthquake had such a big effect on the carmaker's supply chain that a number of its plants will have to be shut down for an undisclosed period, starting on Saturday. The 6.7 magnitude earthquake occurred early on September 6 th, resulting in more than dozen casualties and hundreds of injuries, cutting power to the entire island; the powerplant supplying half of the island's power was located so close to the earthquake's epicenter that it shut down automatically, bringing down the rest of the island's grid with it. Tens of people were also reported missing, as reported by Reuters. The affected factories are the Kyushu, Tahara and Toyota Auto Body plants, according to Automotive News, and they manufacture vehicles such as different Lexus models and the Toyota Land Cruiser. Some of the models produced in these factories are exported to the United States, but a Toyota spokesman said that North American operations are not likely to be significantly affected by the plant closures. As well as the automobile assembly plants in Hokkaido, Toyota also has a facility there that manufactures transmissions and transfer cases. As it was also without power, Toyota could not confirm when the plant would be back online. Out of Hokkaido's 2.95 million households, 1.54 million had regained power by Friday afternoon. All in all, Toyota has 18 manufacturing facilities in Japan; spokeswoman Akito Kita said that from Monday on, the shutdown will affect all Japanese Toyota and Lexus lines — not including two Daihatsu facilities that are also used for Toyota products. The shutdowns come directly after Toyota also announced a recall for Japanese-built hybrid models, mainly Prius. Related Video:
