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 reveals new customizable Camatte57s kid-friendly concepts

Toyota plans to follow up last year's kid-friendly Camatte concept with two new versions: the Camatte57s and Camatte57s Sport (right). Like the original Camatte, the two new concepts will make their debut at the International Tokyo Toy Show, which is happening this weekend.
Not much has changed with these two new Camatte models. Like their predecessor, they both feature detachable body panels (the count is up to 57), a 1+2 seating array and reconfigurable pedals that allow children to operate the gas and brakes while Mom or Dad steers. What is new is an open-top roadster design that even eschews doors in favor of easier ingress/egress. They look like something a tourist would rent to get around a Hawaiian island, though we dig the distinct personalities of each model's design.
Both cars are all-electric, though Toyota hasn't provided any other specifications, like what makes the Sport model sporty besides its more aggressive body panels and silver, black and red color scheme. That's just as well, as neither concept, like the original Camatte before them, is street legal.

Toyota i-ROAD leans its way into the city [w/video]

According to Toyota, the "i-ROAD takes the company closer to its goal of creating the ultimate range of eco cars." As you're surely aware, that range of eco cars includes the enormously successful Prius family, but this new machine is nothing like the hybrid hatchback. And it's not even a car - Toyota calls the i-ROAD a Personal Mobility Vehicle.
Toyota's i-ROAD Concept, which debuts at this week's Geneva Motor Show, is adorned with just three wheels, meaning it's just as much a motorcycle as it is a car, and the driver and passenger sit in tandem style instead of side-by-side. This arrangement allows for a very thin 850mm width, which is about the same as a large motorcycle. Because the cockpit is enclosed, the occupants don't need helmets, nor are they open to the elements outside.
Also like a traditional two-wheeler, the i-ROAD tilts through the turns and when driving on uneven surfaces. Toyota says its computer-controlled Active Lean technology automatically balances the vehicle with no input from the driver.
