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.

400-hp Toyota Hybrid-R Concept gets second teaser

Toyota has released a second teaser of its Hybrid-R Concept, along with an estimation of the show car's power output. Using technology that's "similar to that used by Toyota Racing's TS030 Hybrid race car," the concept is expected to deliver over 400 horsepower.
The press release also mentions that the new concept is based on a current production model. While it's difficult to tell from the sole teaser image of the car's body, rumors are flying that it's related to the Yaris. If that's the case, though, it's difficult to know what to make of this concept. The teaser image is quite dark, but we played around with the exposure and came up with an image that reveals more details about the new concept. Take a look at the related gallery, below, to see the high-exposure image. We'll find out for certain what the Hybrid-R is in a few weeks at the Frankfurt Motor Show. Let us know what you think Toyota's newest concept is in the comments.

Could high demand, low supply doom Toyota Mirai?

Toyota recently gave the world a behind-the-scenes look at the small-scale production of the Mirai hydrogen fuel cell sedan. A team of just 13 people assembles three of them per day, and the Japanese automaker is using this rigorous build process to prioritize quality for each one. Although, there's some concern about whether the Mirai could become a victim of its own, growing success. The company reportedly already has 2,000 orders for the Mirai just in Japan, and an anonymous Toyota executive tells Automotive News that the waiting list is now "two years or something" to receive one. Keep in mind, this figure is before customers elsewhere in the world have any requests in, and the US launch is planned for California this fall with sales in Europe starting this summer. The automaker is keeping North American demand somewhat in check by only planning to move 200 vehicles or fewer on the West Coast in 2015. So, unless Toyota can pick up the production pace, the waiting list seems likely only to grow longer. Automotive News speculates that the company might be in danger of Mirai customers losing interest if they are forced to build anticipation for too long. That especially could be the case with a new Prius likely to be unveiled by the end of the year that could lure folks away It seems that Toyota is trying to react to the higher-than-expected demand for its hydrogen-powered model, though. In December, the automaker invested $168 million to add two more assembly lines for the Mirai's fuel cell stack and hydrogen tank. Related Video:
