Toyota may put Mirai hydrogen fuel cell powertrain into a Lexus

Toyota is hoping to define the world of hydrogen fuel cell vehicles with its uniquely styled Mirai sedan in a fashion similar to the way the Prius pops into people's minds when they think of a hybrid. The Japanese automaker believes it can sell about 700 FCEVs worldwide in the first year alone and build rapidly from there to an estimated 3,000 sales in the US by 2017. Of course, not everyone is completely enamored with the Mirai's design. Toyota is rumored to have an alternative in the works to quell some of those naysayers, possibly taking flagship form with a new Lexus LS powered by fuel-cell tech. The LS FCEV could be unveiled by 2017 to sit at the very top of brand's lineup. According to an inside source speaking to the Australian website Motoring, the front end would feature larger air intakes to cool the electrical components. The fuel cell would reportedly be positioned under the front seat, and the hydrogen tanks would be located under and behind the rear seat. Somehow, Motoring claims that all of this might be lighter than the current LS600hL hybrid, to the tune about 440 pounds. The model is also claimed to offer a range of about 239 miles, just a bit shy of the Mirai's roughly 300 miles. Assuming this vehicle actually exists, the cost for buyers of this flagship would almost certainly ring up at more than the LS600hL's $120,440 base price. Autoblog has reached out to Toyota for any further info about this rumor, one way or the other. If we hear back, we'll update this story with the details.

Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

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.
