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.

Mazda and Toyota formally announce plans to 'make cars better'

Following Monday's report that Toyota and Mazda could be expanding their cooperation, the two Japanese automakers have made it official, issuing a joint press release announcing a "mutually beneficial long-term partnership" that will "make cars better." The two companies will set up a joint committee to figure out the strengths and weaknesses of each party. As we explained yesterday, that likely means Mazda will benefit from Toyota's plug-in-hybrid and fuel-cell tech, while the world's largest automaker can take advantage of the Zoom-Zoom automaker's line of efficient Skyactiv engines. "I am delighted that our two companies can share the same vision and work together to make cars better. I can think of nothing more wonderful than showing the world – together – that the next 100 years of cars will be just as fun as the first," Toyota President Akio Toyoda said in the attached joint statement. Mazda President and CEO Masamichi Kogai echoed that sentiment, saying: "I hope that by working together to make cars better, we can raise the value of cars in the eyes of consumers while also enhancing the manufacturing capabilities of our home, Hiroshima, and all the communities we are involved in as well." Scroll down for the official joint press release. Toyota and Mazda Team Up to Make Cars Better Tokyo, Japan, May 13, 2015-Toyota Motor Corporation and Mazda Motor Corporation today entered an agreement to build a mutually beneficial long term partnership. By leveraging the resources of both companies to complement and enhance each other's products and technologies, the partnership will result in more appealing cars that meet the diverse needs and tastes of customers all over the world. A joint committee will now be set up to evaluate how best to utilize each company's respective strengths. The committee will encourage broad and meaningful collaboration across a range of fields, including environmental and advanced safety technologies. Marking the agreement, Toyota President Akio Toyoda said: "As evidenced by their SKYACTIV Technologies and KODO-Soul of Motion design, Mazda has proven that it always thinks of what is coming next for vehicles and technology, while still managing to stay true to its basic carmaking roots. In this way, Mazda very much practices what Toyota holds dear: making ever-better cars. I am delighted that our two companies can share the same vision and work together to make cars better.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.
