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.

Recharge Wrap-up: BMW plans for retired batteries; automakers support dual-standard chargers

Toyota will test hybrids with silicon-carbide (SiC) power semiconductors. In Japan, Toyota has put the SiC power semiconductors into the power control units of a Camry Hybrid prototype and a fuel cell bus for a year-long test. Research suggests the SiC units will decrease electrical losses while managing power supply, thus improving overall powertrain efficiency. Current power semiconductors account for about 20 percent of electrical losses, and success with these tests could mean more efficient hybrids on the roads in the future. Read more at Hybrid Cars. Automakers from CCS and CHAdeMO camps are supporting dual-standard charging station networks. https://www.autoblog.com/bmw/, Volkswagen (CCS camp) and ChargePoint announced plans to build "express charging corridors" by installing about 100 DC fast chargers, many of which will support both types of charging. Kansas City Power & Light is partnering with Nissan (CHAdeMO camp) and ChargePoint to install DC chargers that "will charge any model of electric vehicle on the market." This leads the folks at Green Car Reports to look into whether this ends the looming standard war between automakers in the US. Read more at Green Car Reports. BMW, Bosch and utility company Vattenfall are making plans for a second life for retired BMW i3 batteries. The Second Life Batteries Alliance project will recycle the old lithium ion battery packs - which can still hold a charge - in off-grid storage and grid-stabilization applications, beginning with a grid storage system in Hamburg, Germany. Bosch has created a battery management algorithm to extend the life of the batteries and make sure they don't cause harm to Vattenfall's facilities. Read more at Transport Evolved.

Toyota wants improved crash scores with midcycle facelifts

The performances of some Toyotas in the Insurance Institute for Highway Safety's (IIHS) regimen of crash tests leave something to be desired. Consider the small overlap frontal crash test: only six Toyota, Lexus and Scion vehicles have undergone the new test, yet all but one of them received a poor rating. Osama Nagata, CEO of Toyota Motor Engineering & Manufacturing North America Inc., says midcycle vehicle updates are in the works to address the safety issues brought to light by the IIHS test, Automotive News reports. He confirmed that the RAV4 is getting safety updates following its crash test performance last month, but he didn't name any other models.
All three Toyotas that were tested - 2013 RAV4, 2012-2013 Prius V, 2012-2013 Camry - received poor ratings. The 2007-2012 Lexus ES 350 and 2006-2013 IS 250/350 also received poor ratings. The only other Toyota Motor Corp. vehicle to score better than poor is the 2014 Scion TC. It received an acceptable rating in the small overlap frontal crash test and is the only recent vehicle in Toyota's line-up to get the IIHS Top Safety Pick+ rating.
The small overlap front crash test measures the safety of a car when its front left corner is strikes an object during an accident, bypassing traditional crumple zones, which deform in a way to protect passengers. In 2009, automakers were alerted to the forthcoming addition of the test, which was first implemented last year, IIHS spokesman Russ Rader says. They responded with differing intensity, he says, pointing out that Subaru and Honda started incorporating design changes early on so their cars would perform well in the tests.
