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.

Toyota's hydrogen fuel cell Mirai isn't good enough to be a Lexus

It looks like the first hydrogen fuel-cell vehicle from Lexus will be faster than previously advertised, but it will get to the market slower than expected. It's all part of the paradox involved with Toyota looking to broaden its fuel-cell technology beyond the Mirai. Either way, the first Lexus fuel-cell vehicle is slated to start sales by the end of the decade, said Auto Express, citing comments from Alain Uyttenhoven, head of Lexus Europe. Uyttenhoven noted that it'd take an SUV to provide enough space to accommodate the packaging for the Lexus fuel cell powertrain. That comment may imply that the hydrogen-fueled powertrain from Lexus will offer similar performance to that of the Lexus RX450h hybrid SUV. That model delivers 300 horsepower and boasts a 0 to 60 mile-per-hour time of about seven seconds. Such a mill would be a departure from what we'd previously reported on Toyota's plans to expand its fuel-cell technology to its Lexus luxury badge. With Toyota believed to be planning to unveil as many as three fuel-cell models in time for the 2020 Summer Olympics in Tokyo, the Japanese automaker said early last year that it may have a Lexus fuel-cell vehicle available as soon as 2017, while reports suggesting the model would be a Lexus LS-based sedan. Additionally, the Mirai's fuel-cell powertrain had been believed to be the platform for the proposed Lexus fuel cell from the moment that model started sales in California last year. Apparently, though, the Mirai's 152-horsepower powertrain, coupled with a full-tank range that would be about 20 percent less than the 300-mile Mirai, isn't up to snuff for Lexus duty.

Anything but boring | 2018 Lexus LC 500 First Drive

This is it, the headliner, the main event. After years of Lexus promising to make less-boring cars and instead giving us countless spindle-grille facelifts, the 2018 LC 500 is here as the brand's new North Star. It's the official halo to mark where Toyota's luxury brand is headed. This is the car that we hope can bring an end to the relentless mentions of boring cars - which are themselves needlessly boring. And besides, "not boring" is a terrible metric for evaluation. What Lexus is really trying to do is give its cars some spirit, to transcend the paint-by-numbers stereotype that made this brand the luxury juggernaut it is today. By that yardstick, the LC 500 is a success simply based on how it looks. It's beautiful in a way that we couldn't predict from the 2012 LF-LC concept that foreshadowed it. The kind of beauty where instead of reflexively grabbing your phone to take a picture, you just stand there and keep looking. And pictures don't do this car justice, anyway. They soften the edges and reduce the massive draw of the wide shoulders. In person, looking straight at the LC, the car looks like it's 80 percent hood. In the rest of the lineup, the trademark Lexus grille's execution ranges from caricature (RC) to botched nose job (LX). Here it pulls everything together. From every other angle, the LC has some feature that seems excessive – in the best way possible. The proportions of the LC give off a distinctively functional vibe, and it's genuine. That hood is so long because the 5.0-liter V8's center of mass sits three and a half inches behind the front axle. The extra space up front is mostly empty - Lexus uses high-strength steel cross-braces to shore up torsional rigidity instead of adding structure ahead of the front wheels, and the battery sits under the trunk floor. For all the visual excitement, the LC is still a conventional vehicle. Aside from some advancements in the LC 500h's hybrid powertain, the innovation here is of the iterative type. It's interesting, in that Lexus is betting on emotional appeal and driving character at a time when the future relevance of both is up for debate. If anything, the LC is a car for the current automotive world, not the one to come. And despite extensive use of aluminum and sheet-molded carbon, the LC 500 weighs in at a hefty 4,280 pounds. That's right in line with the BMW 6 Series and a good deal below the Batali-esque Mercedes-Benz S-Class Coupe's 4,700 pounds.
