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 and Suzuki are looking at an R&D partnership because they admit they're behind

The Chairman of Suzuki Motor Corporation, Osamu Suzuki, and the President of Toyota, Akio Toyoda, have convened at Toyota's Tokyo offices to declare plans to join hands regarding research and development. According to Toyoda, Toyota "hasn't been good at creating alliances," and its partnership with the small carmaker Daihatsu has been the most well-known collaboration so far. Perhaps the comment has a tinge of regret from Toyota and GM's NUMMI days in Fremont, especially as the statement released by Toyota says that "Toyota is conscious of the fact that it may be behind competitors in North America and Europe when it comes to the establishment of standardizations and partnership with other companies." But as different technologies advance at breakneck speed and it is difficult for companies both big and small to stay competitive, let alone ahead of the game, Toyota is accepting the need for collaboration. Toyoda referred to passenger safety, environmental issues, automated driving, and hydrogen technology, all of which are key challenges for any carmaker looking to stay relevant, and all expensive to experiment with. Spreading the cost over more vehicles should help. "We received an offer from Suzuki regarding collaboration possibilities on advanced and future technologies such as in information technology. Suzuki made a frank proposal to us, and in understanding that Toyota is facing the challenges which I had mentioned earlier, we thought that with the relationship between both companies, there is an opportunity for a business partnership to help solve such challenges. As such, we decided to explore such possibilities together," said Toyoda. In the future, Daihatsu will still be Toyota's tool in emerging markets, but now Toyota could have access to Suzuki's small-car know-how. Osamu Suzuki acknowledges that "Suzuki's current business focuses on minivehicles in Japan and India," as Suzuki withdrew from the US and Canada in 2013. A joint effort will help Suzuki remain relevant, and as a manufacturer of predominantly small vehicles it has been focusing on competitive pricing more than cutting edge technology. Related Video:

Toyota sells off Tesla shares, too

The incredible rise of Tesla's stock price has done little to now stop two major shareholders from ditching their stake in the American EV manufacturer. First, Daimler, parent company of Mercedes-Benz, ditched its four-percent stake, and less than a week later, Toyota is doing the same thing, selling off an undisclosed bit of its Tesla investment.
The move comes as Toyota winds down sales of the RAV4 EV, which gets its batteries and electric motor from Tesla at the company's Fremont, CA factory.
"We have a good relationship with Tesla, and will evaluate the feasibility of working together on future projects," Toyota spokesperson Kayo Doi told Bloomberg via email.
