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.

Despite slow sales, no new Scion models in near-term pipeline [w/poll]

According to a top Toyota executive, the Japanese automaker will not be introducing any fresh Scion models in the near future, Reuters reports. As of August, Scion sales for this year were down 1.6 percent from 2012 and accounted for only 0.3 percent of Toyota's overall US sales. And last month, Toyota Motor Sales USA Senior Vice President Bob Carter informed the 1,000 dealers who carry Scion that they can drop the brand without penalty.
However, never fear - Carter has assured that, while nothing new is coming for at least six months, the company is still very committed to the quirky Scion brand. Toyota launched Scion, which targets the youth market, in 2003, and sales peaked in 2006. The brand currently has five models, with the 2013 best-sellers being the FR-S sports coupe followed by the tC sedan and xB hatchback.
What do you think about Toyota's decision to hold off on introducing new or refreshed Scion models? Are they heading in the right direction, or does this spell doom for the funky Gen Y brand?

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.
