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 recalls 370k Sienna minivans, 10.5k Lexus GS models over separate issues

The year of the recall continues, but this time it isn't from General Motors. Toyota is announcing two, separate recalls affecting a pair of its models.
First, Toyota is recalling 370,000 Sienna minivans from the 2004 to 2011 model years that are registered or originally sold in cold-weather states. The problem is that the spare tire carrier assembly cable can be splashed by water contaminated with road salt and cause corrosion. There is a splashguard in place to prevent this, but it sometimes gets lost in "normal usage," according to the company. If the cable does break, then "the spare tire may separate from the vehicle."
This is actually the second repair for this problem for some of these vehicles. In 2010, Toyota issued a recall on 600,000 Siennas from the 1998 to 2010 model years. At the time, it installed a new splashguard and sprayed the area with an anti-rust chemical. However, according to Toyota spokesperson John Hanson speaking to Autoblog, the campaign worked for the 1998 to 2003 models but wasn't sufficient for the newer ones. For the latest recall, the vehicles are getting the entire cable replaced with a stainless steel unit and a new splashguard.

Toyota fills in details about its future design direction and global platform

"In the future, out of 100 customers, we want to excite ten of them instead of not offending all 100."
Almost all of the details about the Toyota New Group Architecture (TNGA) strategy have come out since the initiative was first reported on in March of this year, but Autoblog did learn a few new things about it on a recent trip to Japan. Probably the second-most important detail is that each new segment platform will be based around a common hip point to create an "optimal driving position architecture."
