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 postpones 2021 IS debut indefinitely

The new 2021 Lexus IS sports sedan was scheduled to make its debut today, but Lexus has made the decision to postpone the digital unveiling indefinitely. Lexus cites respect for "the recent global situation" as the reasoning for the postponement.  This week, Lexus released a simple statement on the digital debut of the 2021 IS. "Considering the recent global situation, Lexus has respectfully postponed the premier of the new IS, which was originally scheduled for 8:00 a.m. Japan Standard Time, June 10," it said. "Revised timing will be announced soon." With worldwide outpouring of civil protests in regards to the death of George Floyd, police brutality and the movement for police reform — all in the midst of a pandemic — it seems like a malapropos time to unveil a new car. Autoblog reached out to Lexus for further clarification on when the car would debut, and the company said it hopes to have more news at a later date. When it does debut, the next-generation sports sedan will utilize rear-wheel drive, and we expect all-wheel drive to be an option. According to a report from Motor Trend, the new IS will ride on an evolutionary modified version of its current "New N" platform, as opposed to an all-new setup, but that is unconfirmed. Like the current IS, the upcoming IS will likely offer both four-cylinder and six-cylinder powertrains options, though it is unclear what the power will look like. Related Video:

Lexus teases 2022 LX 600 flagship SUV

Like so many things at the moment, the Lexus LX debut got pushed back, but it's nearly upon us. Toyota's luxury brand began the teaser campaign for the 2022 Lexus LX 600 today, in preparation for an online debut October 13 at 12:30 p.m. Eastern at the same time the vehicle is unveiled live in the United Arab Emirates and Saudi Arabia. We can glean a few things from the teaser, the first being the same Lexus design language we recently saw on the 2022 NX transferred to what will be the automaker's flagship SUV. That means an LED light bar connecting two hockey-stick taillamps above a spelled-out "LEXUS" instead of the Lexus logo. The chrome accents of the LX 570 are history, the rear license plate placed in an unadorned trapezoidal recess. The rear bumper is now nearly flush with the tailgate and loses its stanchions at the edges.    And then there's that LX 600 badge, officially signaling that numbers aren't about engine displacement. Depending on market, the LX is expected to get the twin-turbocharged 3.5-liter V6 that launched with the 300-Series Toyota Land Cruiser in June and puts out 409 horsepower and 479 pound-feet of torque in that model. Japanese outlet Creative Trend says this mill will eventually get hybrid assistance to create an LX 750h trim with 480 hp and 642 lb-ft. of total system output. The 3.3-liter diesel V6 with 305 hp and 516 lb-ft. could end up in places like Japan and Australia, and it's possible a base version with the naturally aspirated V6 finds its way to market.  Toyota said putting the new Land Cruiser on its TNGA-F platform saved about 440 pounds. We won't be surprised if the Lexus loses some weight as well, but we also expect a lot of new tech in the LX 600, and luxury is heavy. Features like the Multi-Terrain Select system and Multi-Terrain Monitor seem like shoo-ins, as does the 360-degree camera system. An option for fingerprint authentication to start the vehicle might bow as well. We'll know next week when the 2022 LX livestream kicks off. Related Video: This content is hosted by a third party.
