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.

Dubai Police conscript 467-hp Lexus RC F into high-performance stable

The Dubai Police Department has added yet another... um, let's call it unconventional, cop car to its ranks. But rather than an ultra-exotic, mid-engined masterpiece, it's the V8-powered Lexus RC F. Finished in the white-and-green color scheme typical of Dubai's fuzz, the RC F was purchased alongside another Toyota product, a utilitarian Toyota Land Cruiser. While the off-road-ready SUV's purpose seems clear, enforcing the emirate's laws in the areas outside the city, the 467-horsepower Lexus will likely follow in the lead of Dubai's other high-performance offerings, appearing more for publicity and public relations than actual law enforcement. Check out a couple shots of the new cop car up top.

Lexus NX rolls on wheels made of ice

To create this rolling ice sculpture, Lexus teamed up with London-based Hamilton Ice Sculptors, which fitted the compact luxury crossover with wheels and tires crafted from ice. The sub-zero craftsmen then deep-froze the entire vehicle, stored it at -22 degrees Fahrenheit, and drove it around London – pleasantly surprised to find that it started on the first try. As far as publicity stunts go, the finished product looks even cooler than the cardboard IS that Lexus had crafted a few months ago or the biometric glow-in-the-dark RC F from this past summer. The project took three months of research, design, and testing to carry out. The wheels replicate the alloys on the NX with millimetric precision, right down to the tread pattern, and each one took a team of four craftsmen 36 hours of work to complete. Of course, blocks of ice would have a hard time supporting the weight of the vehicle – especially while in motion – so the frozen wheels were reinforced with clear acrylic discs. And to make it all glow, they were also fitted with in-wheel LED lighting. This isn't the first time we've seen ice sculptors apply their skills to automobiles, following the frozen Canadian Tire pickup, Toyota Land Cruiser, Nissan Cube, and Saab Aero-X we've seen in recently years. But this one is at least as cool, in one sense or another. Scope out the results in the video above, and the process that went into their creation in the making-of video below.

LEXUS NX RIDES ON THE WORLD'S COOLEST WHEELS – CRAFTED IN SOLID ICE The concept of driving on ice has taken on a whole new meaning for Lexus, which has crafted the world's first set of working wheels and tyres made from frozen water. Brussels, Belgium - True to its mission of "creating amazing" and inspired by the craftsmanship that goes into every vehicle it makes, Lexus commissioned a team of ice sculpture specialists to explore how ice could be used in place of conventional alloy metal and rubber. After three months' research, design and testing, the finished wheels were fitted to a Lexus NX for the ultimate ice drive. The car itself was deep-frozen, stored for five days at -30°C (it started first time) before being driven off down a London road. The addition of in-wheel LED lighting added an extra dramatic dimension to the cutting-edge contemporary styling of the NX.
