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 aims to build autonomous car around 2020 [w/videos]

The race is on to get increasingly sophisticated forms of autonomous driving technology on the road, and brands like Tesla are bringing these solutions to some drivers now. But as one of the world's largest automakers, it's no surprise to see Toyota competing in the field, as well. By 2020, the company thinks a person could be largely unnecessary for freeway trips. With a suite of tech called the Highway Teammate, a modified Lexus GS is already showing what's possible. Using a combination of millimeter wave radar, LIDAR, and cameras, the GS gets a full view of the road, and software processes all of the info to make decisions. The result is a ride on the freeway without human interaction. The system can merge, change lanes, make passes, take curves, and maintain a safe distance from other vehicles. Accurate map data is a necessity to make this work, so the system currently only being tested on Tokyo's Shuto Expressway. While Highway Teammate might not be the best name, it accurately communicates the way Toyota thinks of the tech. The company is making big investments in artificial intelligence to assist drivers, not completely replace them. You can see the system in action in the video below, and the second clip's gravely serious narrator explains the company's idea of having a fully connected road someday.

New Toyota Test Vehicle Paves the Way for Commercialization of Automated Highway Driving Technologies Toyota City, Japan, October 6, 2015-Toyota has been testing a new automated driving test vehicle called Highway Teammate, with the aim of launching related products by around 2020. In addition to demonstrating the capabilities of next-generation safety technologies, the vehicle represents Toyota's view of the evolving driver-car relationship in the age of artificial intelligence. Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out. Toyota refers to this approach as the Mobility Teammate Concept, and Highway Teammate represents an important first effort to give form to this concept.

Hardcore Lexus RC F spied along with facelifted model

The Lexus LC F isn't the only high-performance Lexus spied testing. Another of our spy photographers caught a hardcore version of the RC F sports coupe out testing with its more mild-mannered sibling, the latter of which was trying to hide its mild facelift. Of the two cars, the RC F is the more interesting for a couple of reasons, and not just because it will be the faster of the two. First of all, it looks like this RC F will be significantly lighter than the current model. The weight savings will likely come mainly from new carbon fiber panels that include the bare carbon hood and roof panel. It's possible Lexus will have found some other areas to save weight, but these parts are all we can see at the moment. The other reason this RC F is grabbing our attention is the impossible-to-miss rear wing. Its tall supports, large size and bold end plates signal that this is more of a track car than just a fast road car. Whether it delivers track-car levels of downforce has yet to be seen. The fixed wing is also likely lighter than the power-retractable one on the regular RC F. Another performance upgrade we can see are the giant cross-drilled brakes. One of the big mysteries of this car is of course whether Lexus will have upgraded the powertrain to match the other upgrades. We're not getting our hopes up. Lexus only has two versions of the 5.0-liter V8 (that we know of): the RC F version that makes 467 horsepower, and the LC 500 version that makes 471 horsepower. We could see Lexus using the slightly hotter LC version, but likely nothing new. Part of what leads us to think that is the RC F GT Concept Lexus built for Pikes Peak a few years ago. That car got loads of light parts, a roll cage and a wide body kit, but it had just the same 467-horsepower V8 as any other RC F. View 15 Photos As for the other RC on display in these spy shots, it gives us a solid look at the coupe's upcoming midcycle refresh. Interestingly, it appears Lexus has abandoned the split lights that had the Nike "Swoosh" style running lights. Now everything is integrated into single units. The outboard grilles now have more prominent strakes in them, and there's now a small grille or air inlet at the base of the main grille. Around at the back, there are almost no changes that we can see through the camouflage. Only a possible extension of the diffuser between the rear reflectors is all that shows through.
