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.

Suzuki and Daihatsu join Toyota electric vehicle venture

TOKYO — Suzuki Motor Corp and Daihatsu are joining a commercial electric vehicle coalition led by Toyota Motor Corp, the carmakers announced on Wednesday, helping the Japanese alliance expand its focus from trucks to smaller cars. The two automakers will each acquire a 10% stake in the joint venture, on par with Isuzu Motors and Hino Motors, while Toyota will hold a 60% stake, they said. "With Suzuki and Daihatsu joining the project and working together, we'll be able to expand our circle of cooperation to not only cover commercial vehicles but also mini vehicles," said Toyota President Akio Toyoda. "With this expansion, I believe that we'll be able to take one step closer to a better mobility society," Toyoda said. The move comes as Japanese automakers face growing competition from tech giants and other rivals making electric and driverless cars. Toyota, Isuzu and Hino launched the Commercial Japan Partnership Technologies Corporation in April to bolster their competitive edge in connected, commercial vehicles. Daihatsu's president Soichiro Okudaira said joining the pact and introducing connected, mini-commercial vehicles would allow data sharing, a major benefit for companies to provide better services to customers and improve logistics efficiency.
