Mazda CX-5 named Japan's Car of The Year, Subaru BR-Z wins "Special Award"

The Mazda CX-5 stamped its Kodo design and SkyActiv technology authority all over the Japan Car of the Year awards, taking the top prize ahead of the Subaru BRZ/Toyota GT 86. It is Mazda's second victory in the last ten years, the 2005 MX-5 claiming the same trophy, and the fourth time the Hiroshima company has won.
The award is decided by 60 local "automotive experts and journalists," and open to any passenger car released in Japan from November 1, 2011 to October 31, 2012 that has sold more than 500 units. Each judge gets 25 votes, his or her top vote getting 10 points, the rest of the points being spread among the judge's choice for the next best four cars.
The second-place getters were the Toyobaru twins with 318 votes, the surprise being they didn't beat or get any closer to the crossover. The Subaru BRZ did claw some mojo back, earning the Special Award given to cars that have made "an exceptional impact." The BMW 3 Series was third overall and won the Import Car of the Year award with plenty of room between it and the second place Range Rover Evoque.

Toyota will bring Lexus-based Platform 3.0 autonomous vehicle to CES

The Toyota Research Institute says it will bring its next-generation Platform 3.0 automated driving vehicle to CES next week, an autonomous test car that is notable for incorporating the sensors and cameras into the body, rather than as ungainly attachments, and with the spinning LIDAR rooftop sensor replaced by a more sleek panel of sensors. Platform 3.0 is built on a Lexus LS600hL. Toyota Research Institute says it enlisted CALTY Design Research in Ann Arbor, Mich. and engineers at Toyota's nearby North America R&D center to conceal the equipment. As a result, Platform 3.0 gets a new rooftop weather and temperature proof panel, which it says was inspired by off-road motorcycle helmets, integrated into the available space in the sunroof compartment to minimize height. It's also embellished with chrome trim along the side, where it meets the roofline, and the rear swoops down to integrate with the LS's contour lines. The team also managed to consolidate computational electronics and wiring into a small box in the trunk. Toyota says the Platform 3.0 is one of the most perceptive autonomous test vehicles on the road today, with a design makes the test vehicle easy to build at scale. It gets a Luminar LIDAR system boasting a 200-meter, 360-degree range (the previous version only tracked the forward direction), enabled by four high-res LIDAR scanning heads that help it better see dark objects. Shorter-range LIDAR sensors feature low on all four sides of the vehicle, one on each front quarter panel and on the front and rear bumpers, to detect low-level and smaller objects, like children or road debris. Production begins this spring at the Toyota Motor North America R&D headquarters at low volumes to allow for flexibility, given the rapid rate of development of Toyota's autonomous test platforms. Some will be assembled using Toyota's Guardian dual-cockpit control layout to allow for transferring control between a human test driver and the automated system while keeping the driver as a backup, while the single-cockpit, fully autonomous Chauffeur mode will be shown at CES starting Jan. 9.Related Video: This content is hosted by a third party.

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.
