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 builds world's first 'outdoor website' for RAV4 promo

This whole thing started with the premise that Toyota's target RAV4 buyers are people who spend their time cycling, hiking, and generally not in front of computer screens. These people are therefore not able to benefit from the full website experience that Toyota has built for the RAV4. We should clarify that the video below is for Toyota South Africa, and maybe RAV4 buyers there really are the disgustingly outdoorsy ideal that us bacon-eaters are not living up to.
Toyota's agency partner, Hello Computer, set up a 1.8-kilometer track at a cycle park that replicated sections of the automaker's website with real physical displays and interactive feedback. Riders were asked to leave their mouses and hit the trail on a mountain bike to experience the RAV4 Outdoor Website and learn about the vehicle.
That seems like a lot of effort for something that's available on the smartphones of these hyper-active people who aren't in front of computers, but hooray for creatively conquering a problem that didn't exist. Hey, let's not be complete wet blankets - maybe some of the cyclists that ran the Toyota gauntlet got a RAV4 for their to- and fro-ing after the experience. Check out the video of the outdoor website below.
