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: No plans for LFA replacement anytime soon

Supercars are fantastic in terms of their raw performance, sound and ability to inspire interest in an automaker. They aren't so good at actually making money, even for giant, global automakers like Toyota. And if you are holding out hope that Lexus might be fibbing about there being no plans for an LFA successor, we have some bad news. "I think you will see us do some incredible things in the future, but probably not a $375,000 supercar anytime soon," Lexus Executive Vice President Mark Templin told Automotive News. The issue comes down to the LFA's cost to develop and massive price. Lexus built just 500 of the V10 supercars from 2010 through 2012. Templin said that the plan was originally for a much more modest vehicle with a steel body. However, that intention changed to plans for an aluminum exterior and eventually evolved further to carbon fiber during the course of its engineering. Templin is clear that Lexus isn't giving up on more accessible performance with its F sub-brand models, but more supercars aren't coming, at least not anytime soon. He previously suggested that the LFA was a generational model with a 30-year wait for the next one. These days, the workshop that built the LFA has been converted for a much less powerful but perhaps more important vehicle. Toyota now uses it to build the Mirai with the company's hydrogen fuel cell powertrain.

2016 Lexus GS F revealed ahead of Detroit debut

The last time we heard about Lexus' new Detroit Auto Show-bound performance car debut, all signs pointed to GS F. Now, the cat's out of the bag, and we've got the first official images and details of the Japanese automaker's latest performance sedan, and honestly, it's exactly what you'd expect – though that isn't necessarily a bad thing. Power comes from the automaker's 5.0-liter naturally aspirated V8 – the same eight-pot that powers the RC F – good for 467 horsepower at 7,100 rpm and 389 pound-feet of torque that comes on strong between 4,800 and 5,600 rpm. That force is sent to the rear wheels via Lexus' eight-speed automatic transmission. In order to make this F a significantly better-handling vehicle than the standard GS, Lexus is fitting its Torque Vectoring Differential from the RC F, which uses three modes – Standard, Slalom, and Track – to alter torque delivery to better suit different driving dynamics. Lexus has released a few preliminary specifications about the GS F, so we know the sedan tips the scales at 4,034 pounds and will ride on 19-inch wheels with 255/35-series tires up front, and 275/35 rubber out back. This all sounds pretty good, but we can't help feel a wee bit disappointed, especially considering the numbers being thrown down by competitors like the BMW M5 and Mercedes-Benz E63 AMG, not to mention the new 640-hp, 200-mph Cadillac CTS-V that'll also debut at next week's Detroit show. Still, if the Lexus RC F is any indication of the brand's future performance offerings, we don't doubt the GS F will, at the very least, be a super fun car to toss around. Stay tuned for the GS F's official unveiling, next week.
