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.

Google self-driving Lexus crashes into a bus

Google's self-driving cars have been in accidents before, but always on the receiving end... at least, until now. The company has filed a California DMV accident report (PDF) confirming that one of its autonomous vehicles (a Lexus RX450h) collided with a bus in Mountain View. The crash happened when the robotic SUV had to go into the center lane to make a right turn around some sand bags – both the vehicle and its test driver incorrectly assumed that a bus approaching from behind would slow or stop to let the car through. The Lexus smacked into the side of the bus at low speed, damaging its front fender, wheel and sensor in the process. This was a minor incident, and we're happy to report that there were no injuries. However, this might be the first instance where one of Google's self-driving cars caused an accident. If so, the Mountain View crew can no longer say it's an innocent dove on the roads -- while this wasn't a glitch, its software made a decision that led to a crash. We've reached out to Google to see if it can elaborate on what happened. No matter what the response, it was always going to be difficult to avoid this kind of incident. Until self-driving cars can anticipate every possible road hazard, there's always a chance that they'll either be confused or make choices with unexpected (and sometimes unfortunate) consequences. However, the hope at this early stage isn't to achieve a flawless track record. Instead, it's to show that self-driving cars can be safer overall than their human-piloted counterparts.Related Video:This article by Jon Fingas originally ran on Engadget, the definitive guide to this connected life.

Toyota has two all-new 8-passenger SUVs in the works, and one's a Lexus

Toyota announced yesterday that its Princeton, Indiana, manufacturing plant is getting a big $803 million infusion of cash. The reason? Toyota casually dropped that it will soon build “two all-new, three-row SUVs” there. TheyÂ’ll be “designed with the active Gen Y American Family in mind,” which is another way of saying that Toyota is targeting Millennials. In case you missed it, Millennials are in their late 20s and 30s now! That means they have growing families and need more space to put them. Both new SUVs will seat up to eight passengers. The other big reveal is that both will be electrified. WeÂ’re going to assume that means theyÂ’ll be regular hybrids in ToyotaÂ’s case, though thereÂ’s every possibility for a PHEV “Prime” version, too. Both will have semi-automated driving systems, advanced enough that they will “allow for hands-free driving in certain conditions.” Plus, there will be a remote parking system that allows “the driver to park and unpark outside the vehicle using a smartphone.” The last nugget of tech Toyota is sharing with us is that both will use a new “digital key” that turns your smartphone into a quasi key and allows you to share it digitally with others. Another bit of information concerning these two is that one will be a Toyota, and the other will be a Lexus. What these two models will be named is not yet clear. Seeing “three-row SUV,” our minds instantly go to Sequoia. That model is as old as it gets these days, and is deeply in need of a redesign — the current generation launched all the way back in 2008. However, Toyota does not explicitly say that this news pertains to the next-gen Sequoia. In fact, previous reports of the Sequoia shifting its production location to San Antonio lead us to believe that this news has absolutely nothing to do with a potential next generation of the SUV. Coincidentally, the Sequoia is currently built at the Princeton, Indiana, plant thatÂ’s getting this investment — that official switchover to Texas is reported to happen sometime in 2022.  ToyotaÂ’s language in this press release, plus the knowledge that Sequoia is leaving Indiana, all indicates that these two three-row SUVs might not be rough-and-tumble body-on-frame off-roaders. TheyÂ’re likely going to be plenty capable (hitting that “active lifestyle” market), but the focus toward families suggests that comfort could be paramount.
