Toyota retires robots in favor of humans to improve automaking process

Mitsuru Kawai is overseeing a return to the old ways at Toyota factories throughout Japan. Having spent 50 years at the Japanese automaker, Kawai remembers when manual skills were prized at the company and "experienced masters used to be called gods, and they could make anything." Company CEO Akio Toyoda personally chose Kawai to develop programs to teach workers metalcraft such as how to forge a crankshaft from scratch, and 100 workstations that formerly housed machines have been set aside for human training.
The idea is that when employees personally understand the fabrication of components, they will understand how to make better machines. Said Kawai, "To be the master of the machine, you have to have the knowledge and the skills to teach the machine." Lessons learned by the newly skilled workers have led to shorter production lines - in one case, 96percent shorter - improved parts production and less scrap.
Taking time to give workers the knowledge to solve problems instead of merely having them "feed parts into a machine and call somebody for help when it breaks down," Kawai's initiative is akin to that of Toyota's Operations Management Consulting Division, where new managers are given a length of time to finish a project but not given any help - they have to learn on their own. It's not a step back from Toyota's quest to build more than ten million cars a year; it's an effort to make sure that this time they don't sacrifice quality while making the effort. Said Kawai, "We need to become more solid and get back to basics."

Mazda CX-5 named Japan's Car of The Year, Subaru BR-Z wins "Special Award"

The Mazda CX-5 stamped its Kodo design and SkyActiv technology authority all over the Japan Car of the Year awards, taking the top prize ahead of the Subaru BRZ/Toyota GT 86. It is Mazda's second victory in the last ten years, the 2005 MX-5 claiming the same trophy, and the fourth time the Hiroshima company has won.
The award is decided by 60 local "automotive experts and journalists," and open to any passenger car released in Japan from November 1, 2011 to October 31, 2012 that has sold more than 500 units. Each judge gets 25 votes, his or her top vote getting 10 points, the rest of the points being spread among the judge's choice for the next best four cars.
The second-place getters were the Toyobaru twins with 318 votes, the surprise being they didn't beat or get any closer to the crossover. The Subaru BRZ did claw some mojo back, earning the Special Award given to cars that have made "an exceptional impact." The BMW 3 Series was third overall and won the Import Car of the Year award with plenty of room between it and the second place Range Rover Evoque.

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.
