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.

2015 Lexus NX 300h

With so much hullabaloo being made over the first gasoline turbocharged engine produced by Lexus, it's easy to forget that there's another option for those who'd rather (barely) hear the whirring of electric motors than the high-pitched whizzing of turbos. That's too bad, because we think the NX 300h is one of the more interesting hybrids on the market, due in large part to its innovative all-wheel-drive system and relatively sporty driving dynamics. We spent several hours with the brand-new hybrid crossover from Lexus, and we came away with plenty to talk about.
Driving Notes
Of course, the big thing that differentiates the 300h from the 200t is its drivetrain. In place of the 2.0-liter turbocharged four-cylinder sits a 2.5-liter gasoline engine that runs exclusively on the Atkinson cycle to save fuel, augmented by a pair of electric motors and mated to an electronic continuously variable transmission. Lexus is no stranger to hybrids, buoyed by parent company Toyota's expertise, and the basic setup used by the NX 300h is a well-known quantity shared with the ES 300h.

Japanese dealer petitioning Lexus for luxury van [w/poll]

Used to be that if you wanted a luxury automobile - especially one to be chauffeured around in - your choices were basically limited to a sedan. It could be bigger or smaller, more or less expensive, depending on your needs and budget, but it was always going to have four doors and a trunk. But these days the rich and famous are looking elsewhere for their commodious forms of pampering transportation. There are, of course, the crossovers and SUVs, which only seem to be getting bigger and more expensive thanks to the likes of the Mercedes-Benz G-Class, Range Rover L and upcoming Bentley sport-ute. But luxury vans are becoming the new big thing.
That's the point that one dealer in Japan is trying to make to Toyota. The dealership owner himself reasons that if he's going out on the town, he's likely to take his chauffeured Lexus LS. But if he's taking a few friends along, even the biggest sedan isn't going to cut it. So he takes a Toyota Alphard (pictured above, also known as the Vellfire), a JDM van that's even bigger than a Voxy/Noah or Sienna but hardly a high-end affair. That's why he's asking Lexus to make a luxury van.
The idea may seem a little far-fetched, but isn't without precedent. It didn't take much for Lexus to transform the Land Cruiser into the LX and thus create its first luxury SUV. And as Mercedes has shown with pimped-out versions of the Sprinter and now with the debut of the new V-Class in Geneva, there's clearly a market for it... in some countries, anyway. The only question in our minds is how long it's going to take other luxury automakers to catch on, because let's face it: the Chrysler Town & Country ain't gonna cut it for those used to be driven around in a Maybach.
