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 Pro/Celebrity Race Scion FR-S [w/video]

Toyota has been hosting its Pro/Celebrity race at the Toyota Grand Prix on Long Beach since 1977. The charity event, which has raised millions of dollars over the years, traditionally pits Hollywood celebrities against professional athletes (including race car drivers) on the full Grand Prix course in modified street vehicles. The short, sprint-style race is popular with the crowds as the amateur drivers race uninhibited - the result is an action-packed race with plenty of excitement and automotive... er... carnage.
Over the decades, the drivers have raced a variety of Toyota products including last year's front-wheel-drive Scion tC. But this year, Toyota announced at the Chicago Auto Show that the new rear-wheel-drive Scion FR-S would be stepping up to the plate. The good news only became better when Toyota Motorsports invited us out to Southern California's Willow Springs Raceway (the same circuit where the drivers train and practice) to be one of the first behind the wheel.

Toyota and Lexus show off advanced safety research vehicle [w/video]

While Google and Audi explore the possibilities of autonomous vehicles, Toyota and its Lexus division are studying the intermediate step of vehicles equipped with a deep suite of technology that help drivers make the best decisions. Introduced at this week's Consumer Electronics Show in Las Vegas, the Lexus advanced safety research vehicle is an LS sedan fitted with three high-def color cameras to detect objects up to almost 500 feet away, 360-degree Light Detection and Ranging (LIDAR) lasers that can detect objects up to 220 feet away, three radar units to keep track of other vehicles at intersections, a precision odometer on the rear wheel, GPS that estimates orientation and an accelerometer.
Currently testing at a purpose-built 8.6 acre urban testing ground at the Higashi-Fuji Technical Center in Susono, Japan the Toyota research vehicle is being used to study how to make better drivers, as well as figuring out how to reduce crashes as the industry's journey through passive and active safety systems progresses. In the event of a crash, new rescue systems are also being tested.
Further investment is being put into the Intelligent Transportation System (ITS) that would use shortwave signals to harness information from the car and from other vehicles on the road, as well as roadside infrastructure and even pedestrians. Toyota reasons it could then build a picture of interactions and, for instance, alert the driver to a potential collision at a blind intersection.
