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.

Lexus jumps head first into turbocharging with its 2015 NX 200t

If Lexus is going to stay competitive, it needs to turbocharge sooner rather than later.
If there's anything that Lexus is experienced with, thanks in large part to its corporate parents at Toyota, it's hybrid powertrains. The automaker has hybridized tiny little four-cylinder engines, massive honkin' V8s and everything in between. So synonymous are hybrids and Lexus that it would be a shock to see a brand-new model released without an accompanying version with blue badging and a little "h" appendage to its name.

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.
