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 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."

How many Toyotas are potentially affected by seat fabric problem?

When we reported yesterday on Toyota's stop-sale order of certain 2013 and 2014 models due to an issue with the fabrics on models with heated seats not conforming to flammability regulations, one of our many questions was how many vehicles were affected? More importantly, how many of those cars have already found homes?
Kelley Blue Book has the troubling statistics. Every 2013 and 2014 Avalon features heated seats. 6.2-percent of 2013 and 4.5-percent of 2014 Camry sedans, meanwhile, were sold with heated seats. That doesn't seem as bad as 100-percent of the larger Avalon, until you consider the Camry's huge volume - the 5.6-percent average still accounts for a lot of cars. Sienna minivans are heavily affected as well, with a total of 37-percent of 2013s and 46-percent of 2014s fitted with butt warmers. The stop-sale only affects 7-percent of 2014 Corolla models, but like the Camry, that number is rather misleading due to the sheer volume of cars Toyota moves. You can see the entire breakdown of percentages by clicking on the inset image.
According to Karl Brauer, a senior analyst for KBB, this problem comes at the worst possible time. "Given that much of the US is currently in the grips of a record cold snap, there's sure to be high demand for models with seat heaters," Brauer notes. The stop-sale order is a good first step, but it doesn't do anything to inform consumers who currently own the affected models and may, in these frosty temperatures, want to use their seat heaters. "Should owners of those vehicles stop using the seat heaters?" Brauer asked.
