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.

2018 Lexus LC 500 | Drivers' Notes

The 2018 Lexus LC 500 is the latest and greatest sports coupe from Japan. The 471-horsepower luxury spaceship looks like something straight off the auto show floor. Few cars have made the transition from concept to production with so little change, and unsurprisingly, the LC gets plenty of attention. While sports cars are great on winding roads and flat-out around a racetrack, the compromises in pursuit of performance can show when you actually try to live with one every day. That said, a car that pulls at your heartstrings can be forgiven for a lot. Senior Green Editor John Beltz Snyder: On my night with the Lexus LC 500, I was tasked with picking up my toddler, Wolfgang, from daycare. I wondered if I'd even be able to shoehorn the child seat into the coupe's tiny rear row. I moved the front passenger seat up as far as it would go and folded it forward, unclipping the seat belt from the shoulder strap holding it in place. I was able to get the child seat in its rear-facing position (my son's not quite two years old), and was happy to see that the LC had latch brackets, which made installation a little easier. I had to leave the passenger seat moved up and leaning forward, but the child seat fit properly. When I escorted Wolfgang out of daycare and to his ride, he said "Crazy car, Papa." Then I had to climb in the rear seat on the driver's side to clip him in. Totally worth it, though. He loved the car, and wanted to check it out more completely when we got home. And the LC 500 got a lot of looks from other motorists. Rubberneckers slowed down to check out the car on Woodward, and lingered as they passed me on the highway. The one thing I couldn't share with them was the full song of the car's 5.0-liter V8. Only in a couple instances when I was alone on a clear, country road could I mash the right pedal to enjoy the throaty sound of the exhaust as the engine revved to the top. In regular traffic, with a 10-speed automatic transmission keeping the revs low, the sound is much more subdued. This content is hosted by a third party.

The curves, the angles, and the creases all work in harmony to create the rare design that's busy yet also cohesive. Everything plays a role, even if it's a bit over the top. It attracts a lot of attention.

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.
