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.

The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.

Lexus, Mazda and Subaru top Consumer Reports Brand Report Cards

A revised methodology in devising its annual Car Brand Report Cards has seen Consumer Reports award Lexus its top overall ranking for 2013. For the first time ever, the institute broke out individual brands from their larger corporate umbrellas, meaning car makers like Lexus and Scion were judged independently from parent company Toyota. That strategy worked out well for Lexus, as the luxury brand earned a top report card score of 79 for the 2013 model year.
The institute has recommended every one of the Lexus models it has tested to date, and said that the company's products won out thanks to "a foundation of plush and very reliable vehicles."
Meanwhile, Mazda and Subaru tied for the second-highest scoring report cars, with scores of 76. Subaru earned praised for sporting models like the BRZ, which CR testers apparently had a lot of fun driving (naturally), while the Mazda products were lauded for their blend of practicality, sportiness and efficiency. Both of the Japanese brands offered good handling, fuel economy and versatility, said Consumer Reports.
