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.

Lexus LS 500 Inspiration Series is a limited extra-luxe edition of the flagship sedan

Lexus is continuing its trend of making its “Inspiration Series” of cars, and the latest model to get the treatment is the LS 500. Just like all the others before it, this one is mainly an appearance package meant to set it apart from other LS 500s on the road.  The first unique touch is its Deep Garnet paint that isnÂ’t available on the normal LS 500. Then you get 20-inch black chrome wheels that go quite nicely with the paint color. Lexus didnÂ’t forget the Inspiration Series interior, either. Standard is the ultra-luxe Kiriko glass trim you can get as an option on the regular LS 500. It looked stunning on that car, and itÂ’s going to look great combined with the white leather seats on this one, too. Lexus is also giving the Inspiration Series blue LED dash lighting and “Lexus” puddle lamps below the doors. There are only going to be 300 LS 500 Inspiration Series cars sold in America, and theyÂ’re going to be available to buy this fall. Mechanically, itÂ’s exactly the same as a regular LS 500 with the 3.5-liter twin-turbo V6 making 416 horsepower and 442 pound-feet of torque. As for pricing on this limited-edition model, Lexus isnÂ’t saying quite yet. A regular LS 500 similarly equipped is around the $100,000 mark, so look out for something in that range when we do get a price. Related Video:

Watch an Aventador, Viper and LFA play the songs of their people

Our friends at Road & Track recently stopped by Cars and Coffee in Irvine, California, with the 2013 SRT Viper and found themselves a place to park between a Lamborghini Aventador and a Lexus LFA. Those machines might as well be the three musketeers of ludicrous exhaust notes, and rather than keep those 24 raging cylinders muffled, R&T set about conducting an orchestra of internal combustion. On seeing these three lined up, we were more than prepared to call the Viper victorious when it came to tickling our ear drums, but the latest domestic V10 sounds down right civilized in this company.
If we're picking favorites, we have to say the LFA takes the cake. There's something about the noise of a street-legal V10 that can wrap it's tachometer all the way to 9,000 rpm that turns our knees to quivering dollops of jelly. Check out the clip below for a listen. We shouldn't need to tell you to get frisky with the volume.
