Lexus gives IS early updates for 2015

After just a year on the road, Lexus is bringing some modest tech and style upgrades to the 2015 IS. There are no mechanical changes to speak of, but the refinements should spruce things up a little bit.
The only exterior change for the 2015 IS models is the addition of LED foglights, but as they say, it's what's on the inside that counts. All models get an improved radio with Siri Eyes Free voice command for iPhone 4S and 5 users, and the standard backup camera now includes dynamic grid lines. There is also new piano black trim around the instrument panel and window switches, and a Stratus Gray interior color replaces the previous Light Gray. Buyers get a one-year subscription to the Lexus Enform Remote, which allows drivers to use their smartphones to control some aspects of the car, like remotely locking the doors.
Vehicles ordered with the F Sport package get heated and ventilated front seats, and all-wheel-drive F Sport models get a heated steering wheel, as well. The warmed wheel is also optional on non-F all-wheel-drive models. It should keep drivers nice and toasty in the winter.

Final Lexus IS F rolls off assembly line in Japan, bound for US

We knew this day would come, but it's nonetheless a bit of a sad one for Lexus enthusiasts as the very last example of the IS F has rolled off the assembly line in Tahara, Japan. Decked out in its trademark bright blue, the final IS F is destined for a customer right here in the United States.
Far from just another now-defunct model in an endless succession, the IS F marked the first time that Lexus did a proper performance model, debuting in production guise at the 2007 Detroit Auto Show alongside the LFA concept long before the latter entered production and took the idea of the high-performance Lexus even further. The IS F may not have sold in huge numbers, but it definitely marked a milestone for Toyota's luxury division.
Don't cry too much, however, as the new RC F that effectively takes its place packs an even mightier punch. While both are powered by essentially the same 5.0-liter V8 engine mated to an eight-speed automatic driving the rear wheels, the outgoing sedan's 416 horsepower and 371 pound-feet of torque is easily outgunned by the new coupe's 450 hp and 383 lb-ft.

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.
