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 LC convertible confirmed for production

The rumors were true, the Lexus LC convertible is going into production, and we got our first look at the production model at the Goodwood Festival of Speed. Unfortunately, our first look at the production car is of a camouflaged example. The good news is that it looks pretty much just like the concept that was shown in full at this year's Detroit Auto Show. And that car looks just like the coupe minus a roof, and the coupe is a stunner. Lexus didn't reveal any other details about the production LC convertible. It didn't even give a specific date, only saying it will "go into production in the near future." We're assuming the only major mechanical changes will have to do with the roof and chassis, meaning it will have the same powertrains as the coupe. Those include a sumptuous naturally aspirated 5.0-liter V8 making 471 horsepower and 398 pound-feet of torque and a hybrid V6 making 354 horsepower. The V8 and its 10-speed automatic sounds amazing, as you can see in the video below, and the hybrid is paired with a fascinating transmission that earned it our 2018 Tech of the Year award.    

Lexus teases Detroit-bound F Performance Coupe... again

A few weeks ago, Lexus released a teaser image of its upcoming Detroit Auto Show reveal, simply calling it the "next Lexus F." Now, a new shot of the Detroit-bound car has been sent out, and while we still don't know what the new model will be called, we can tell you this: it's a coupe.
Originally, we assumed the new Lexus F model would be the successor to the IS F sedan. But now that we know it'll be a two-door, it stands to reason that this could be the performance oriented version of the 2015 RC coupe that made its debut at the Tokyo Motor Show earlier this year. Of course, Lexus is still keeping quiet on any specifics, simply stating that the company "will unleash its upcoming F model as a coupe, conceived with grit, an entirely new expression of design and uncompromising performance."
The official name of the new F model is set to be revealed in early January, likely just before its official debut in Detroit. Stay tuned for more, and scroll down to read Lexus' very brief press blast.
