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 to replace GX SUV with new TX crossover

There's been a lot of news regarding future Lexus products recently, including spy shots of new RC coupe and NX compact crossover, and reports that a 2+2 coupe based on the LF-LC concept is heading for production. Now, Automotive News says that Japan's #1 luxury automaker is planning to replace the fullsize, body-on-frame Lexus GX SUV with a three-row crossover called the TX.
The article says that the GX, which is based on the foreign-market Toyota Land Cruiser Prado, will get a styling update for 2014 before being phased out in 2016. In a similar move as Infiniti made with its new three-row JX/QX60, the new TX will be car-based, but details are still unknown as to whether it will be front-wheel-drive riding on the Toyota Avalon platform or rear-wheel-drive using the Lexus GS platform. Either way, this new luxury crossover could join the Lexus lineup as soon as late 2016.

2021 Lexus LC gets modest updates including less weight, new colors

The Lexus LC is already one of our favorite cars, and the 2021 Lexus LC aims to be even a little better. The luxury automaker has made a number of minor changes to the suspension, infotainment and color schemes. Starting under the skin, Lexus found some weight savings in the wheels and suspension. In fact, the new LC has 22 fewer pounds of unsprung weight thanks to lighter rear wheels, aluminum lower control arms, high-strength steel springs, and tubular anti-roll bars rather than solid ones. Lexus says that these improvements along with retuned shocks should give the new LC a softer, smoother ride. That's not all, as Lexus is now including its Active Cornering Assist technology to the stability control system, which brakes the inside wheels in turns to improve cornering ability. Lexus also adjusted the shift logic for the transmissions in both the V8 LC 500 and hybrid LC 500h to be smoother and more responsive. Users of Android phones will also be pleased to know that Android Auto will be standard equipment on the 2021 LC. Apple CarPlay and Amazon Alexa integration will also continue to be standard. So however you like to interact with your phone and media, you'll be covered. There are a few color updates, too. Cadmium Orange and Nori Green Pearl have been added as exterior colors. The latter you may remember from the limited edition 2020 Lexus Inspiration Series model. Inside, black and tan interiors stick around, while the Rioja Red option is replaced by Flare Red. Sadly, the Bespoke White interior, which featured indigo and orange leather and suede has been discontinued. Pricing and availability for the 2021 Lexus LC has not yet been announced.
