8 car technologies designed to keep you safe

Technologies are always advancing forward, especially in your vehicle. As more safety technologies are being introduced into the market, it can be hard to keep track of everything. So here are 8 technologies designed to keep you safe on the road. Want more coverage?

Toyota's refreshed Sai is a Lexus HS by any other name

Toyota first launched Lexus in the United States back in 1989, but it wasn't until 2005 that it brought the luxury marque home to roost. But don't think that Toyota didn't find a way of selling many of its premium models in the Japanese Domestic Market in the meantime. The Lexus LS was sold as the Toyota Celsion, the ES as the Vista and Camry Prominent, and the SC as the Soarer. (We could go on, but you get the point.)
These days Lexus sells in markets around the world, including Japan, but Toyota still spins off its own versions of Lexus models to sell domestically as well. Like the new Sai, for example. Sharing its platform, hybrid propulsion and much more with the Lexus HS (which you may remember as the world's first dedicated luxury hybrid until it was pulled from the market early last year), the Sai was introduced to Japan at the same time as the HS was rolled out around the world. Now nearly four years on the market, Toyota has given it a bit of a refresh.
Boasting a far more aggressive front end and a restyled rear, the revised Sai features LED headlights, 16-inch alloys and a higher-quality interior in which JDM buyers will find a new center console and trim, along with an optional 10-speaker infotainment system. Toyota also boasts that the new Sai is made of 20-percent Ecological Plastic and recycled resin.

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.
