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 Toyota Tundra TRD Pro

Despite the earnest efforts of Japanese automakers like Toyota and Nissan, the American pickup truck scene remains wholly dominated by the likes of Ford, General Motors and Chrysler. This is not news. Part of the reason is because of the sheer number of variants offered by US automakers - everything from work-spec base trucks to house-leveling heavy duty models can be had, with a seemingly endless combination of engines, cab sizes, bed lengths and trim levels. It's a hugely profitable business, and though the Japanese automakers still offer competitive fullsize trucks, in terms of sheer volume, they simply don't compete.
But American pickups aren't just about work; there's a huge play aspect involved, too. Look at the desert-storming Ford F-150 SVT Raptor or the Ram Power Wagon - these butch trucks are built with superb off-road prowess in mind, and Detroit's Japanese rivals have once again largely been silent in this segment. Until now.
Introduced at the 2014 Chicago Auto Show, Toyota now offers the TRD Pro series of models that, in addition to the crazy-orange Tundra seen here, includes the smaller Tacoma pickup and 4Runner SUV. And this isn't just some pretty appearance package, either - there's honest-to-goodness capability baked into all of the TRD Pro models. Intriguing, for sure, so I recently spent a weekend with the big boy Tundra to see what's what.
