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.

Lexus LF-LC GT ready to hit Gran Turismo

Lexus might not have as rich a motorsport history as its parent company Toyota does, but it's not been without its racing activities – fielding the LFA in the VLN series at the Nurburgring and powering Daytona Prototypes in American endurance racing, but especially in Japan's own Super GT touring car series. That's where it recently rolled out the RC F GT500 is to replace the aging SC430, fighting for the championship last season right up to the bitter end. And this year it will bring a similar version of the RC F to GT3 racing as well. But before it does, the Japanese automaker has given us another racing machine to lust over – only this one is just for the virtual reality of Gran Turismo 6. Following the two teaser images that previewed its reveal, Polyphony Digital (the studio behind the Gran Turismo franchise) has revealed the new Lexus LF-LC GT. The latest in the Vision Gran Turismo series of virtual racers, the Lexus concept starts with the LF-LC show car revealed at the Detroit Auto Show back in 2012, but applies to it some of the same queues as the aforementioned RC F racer. The bodywork melds into extended aprons to keep the car glued to the digital track, there's a side-exit exhaust, carbon hood and roof, a giant rear wing, gargantuan diffuser and lightweight alloys on racing slicks. It's even got the rainbow-swirled white paint job of the RC F GT3 concept. Technical details weren't released, but then this concept wasn't designed to hit any real road or track any time in the near future, anyway. Related Video:
