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.

Toyota sold record 1.52 million hybrids in 2017

Toyota has been selling electrified cars for more than two decades now, launching the Prius hybrid in Japan in 1997. Back in the fall of 2015, the automaker announced a number of goals as part of its "Environmental Challenge 2050." One of those was to sell 1.5 million hybrids (including its Lexus brand) annually by 2020. Toyota has announced that is has already achieved that goal, selling 1.52 electrified vehicles in 2017. That's an 8 percent increase of Toyota's 2016 hybrid sales, and means the company has sold more than 11.47 million electrified vehicles since it began. Toyota says that represents a reduction of more than 90 million tons of CO2. Last year's achievement "is a testament from our customers to the quality, durability and reliability of our electrified powertrains," says Toyota Executive VP Shigeki Terashi, "and, thanks to them, has led us to establish a solid and sustainable foundation for mass producing a more diverse portfolio of electrified vehicles across our range moving forward." Other goals of Toyota's Environmental Challenge 2050 are 30,000 annual fuel cell vehicle sales by 2020, mass production of battery electric vehicles in 2020 and annual electrified vehicle sales of 5.5 million by 2030. These are all part of Toyota's larger goal of reducing new vehicle CO2 emissions by 90 percent by 2050 (compared to 2010). Prior to 2016, Toyota hybrid sales peaked in 2013, at 1.28 million before slumping slightly in 2014 and 2015. Toyota saw an uptick and a new record in 2016, at 1.4 million, before setting yet another record in 2017, at 1.52 million. Related Video:

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.
