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 pushing upmarket as others move down, LF-LC production hinted [w/video]

Jeff Bracken, Lexus' US group vice president and general manager, knows his company lost its position as America's biggest luxury brand back in 2011, and it's a mantle that his employer probably won't be getting back any time soon. That's because Lexus is electing not to follow the luxury segment's downmarket trend any more than its $32,500 CT 200h hybrid hatchback. "Since we won't be going down below $30,000, it will be very difficult for us to ever regain luxury leadership," Bracken admitted on Autoline After Hours late last week.
Rivals Mercedes-Benz, BMW and Audi all have new low-end entries on sale or in the wings to entice new buyers and fortify their CAFE scores, but Lexus has Toyota and Scion to capture sales underneath its lineup. Instead, Bracken hints that Lexus is going upmarket and higher-performance, fueling ongoing rumors of a LFA successor, or perhaps a new offering based on the lauded 2012 LF-LC coupe concept shown above, a production version of which could also slot in where the unloved SC convertible left off. "We need to begin bringing to market luxury performance... higher performance vehicles. IS-F certainly was the beginning of that, maybe on the lower end," says Bracken.
Later in the online video interview show, Bracken gets even more candid:

2022 Lexus NX First Drive Review | Believe us, it really is all new

The 2022 Lexus NX is at once a safe evolution of the product it replaces and a significant redesign with long-lasting implications. Its dimensions and styling are so similar to the outgoing NX that you'd be forgiven for thinking it's merely a mid-cycle refresh, but indeed, it's a ground-up re-do based on new underpinnings. Sure, they're shared with every front-wheel-drive Toyota group product introduced in the past four years, but then, that's part of the "safe evolution" bit.  Now, there's nothing inherently wrong with such an approach to a new model. Although the NX has never been considered a class leader since it was introduced for 2015, it nevertheless enjoyed strong sales – you know, just like the Lexus ES, RX and name-a-Toyota – vehicles that car enthusiasts might scoff at but everyone else appreciates for their build quality, dependability, resale value and general competence.  Although, if we're talking competence, it's at least worth pointing out one element of the Lexus formula that all those loyal buyers have somehow been putting up with: the Remote Touch tech interface and the infernal touchpad that's been in use, with a few exceptions, in every Lexus since it debuted in Â… that's right, the original NX. And here's where the long-lasting implications of the all-new 2022 NX come in: Remote Touch is gone and in its place the new "Human Machine Interface" touchscreen infotainment system will be making its way through the brand. This is a very big deal, because it means a very real and annoying reason for not buying a Lexus is about to go away Â… and isn't present at all in the new NX.  That said, the new touchscreen not only represents the most important change and improvement to the NX, but the most significant missed opportunity. WeÂ’ll cover that in-depth in a followup infotainment review, but in short, the system thinks too highly of voice commands and could really use the ability to show multiple sources of information at once. Otherwise, the two available touchscreens (a base 9.6-inch unit and a 14-inch widescreen upgrade) feature a UI that's quicker, prettier and easier to use. I was able to jump into the new NX and quickly figure it all out, which definitely can't be said of other luxury systems that continue to perplex after multiple uses, including MercedesÂ’ MBUX and Remote Touch. Those trims with the 14-inch screen also pair with a unique set of steering wheel buttons.
