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.

177k Toyota Camry Hybrids being recalled for brake issue

It looks like Consumer Reports might be getting part of what it wants regarding the Toyota Camry Hybrid and its braking system. Toyota is issuing what it calls a limited service campaign, rather than a full recall, covering about 177,500 of the hybrid sedans from the 2007 through 2011 model years because of an issue with the cars' brake fluid reservoirs.
The models have a filter separating two chambers of the brake fluid reservoir, and the part can get clogged over time. If this happens, the fluid level in one of the chambers can get too low and eventually cause the power assist to fail. There are multiple warning lights on the dashboard that illuminate over time if the filter gets obstructed, though. The company is replacing the entire reservoir with an improved unit, and the fix takes about two hours to perform.
Consumer Reports recently began asking for a recall on these models for the potentially clogged filters. The magazine also reported a second issue with the ABS brake actuator that could lead to a difficult to depress brake, but Toyota has increased the warranty on the part to 10 years or 150,000 miles.

Toyota Mirai might be the name of new fuel cell car; it means 'future'

Anybody remember the Ford Futura? It wasn't exactly a world-beater of a car, so we don't think the name Toyota's has apparently chosen for its first production fuel-cell vehicle is a tribute of sorts. Though one never knows. Maybe Toyota just likes 18-inch-tall EVs. The Japanese automaker has apparently settled on a nameplate for its fuel-cell model, and the name will be "Mirai," which means "future" in Japanese, Bloomberg News says, citing a person familiar with the process that it didn't identify. Bloomberg couldn't get anyone with Toyota to comment on record about the name – and neither could AutoblogGreen – but we do remember that Toyota has bandied this name about before, so we're not setting anything down in stone quite yet. Last month, Toyota said the new fuel cell car would debut in Japan next April and would be priced at about $69,000 before any sort of government incentives kicked in. The company hasn't revealed details about a US release date or pricing here, but indicated that US sales would start where there's already some semblance of a hydrogen-refueling infrastructure. That pretty much means California and nowhere else in the states. The fuel-cell model is said to have a full-tank range of about 435 miles and that the tank can be filled up in about three minutes, similar to a gas-powered vehicle. In other words, the future.
