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.

Toyota and Lexus recalling 235,000 hybrid CUVs and sedans over separate issues

When it rains, it pours. Toyota has announced a pair of separate but voluntary North America recalls covering approximately 235,000 vehicles built between 2006 and 2011. The larger of the two recalls targets Toyota's hybridized crossovers, the Lexus RX400h and Toyota Highlander Hybrid. 133,000 units, including 2006-2010 Highlander and 2006-2008 RX crossovers are covered in the campaign. The other recall affects 102,000 IS350 sedans, IS350C convertibles and GS350 sedans built between 2006 and 2011.
With the CUVs, the faults in the parallel circuits of the transistors can cause heat damage in the inverter assembly, triggering an abundance of warning lamps and sending the vehicle into limp mode. The Lexus sedans are being recalled due to loose bolts on the variable valve timing controller. Detected by unusual underhood sounds on startup, the issue can cause the engine to stop while driving. The inverter issue is also triggering similar recalls in Japan and Europe.
At the moment, it's unclear if any of these issues have caused any crashes or injuries. Toyota says it plans to notify owners of the recall via snail mail. Additional information for owners can be found on the recall sites for Toyota and Lexus or by calling Toyota's customer service line, at 1-800-331-4331.

Lexus resurrecting SC name for big, expensive coupe

Lexus is preparing the SC nomenclature for its third act, after the first bombshell SC coupe from 1991 and the second, Desperate Housewives hardtop convertible evolution from 2001. The brand is aiming again for something that makes a deep mark, with rumored specs pointing to a large, heavy, powerful coupe that will square its spindle grille up against the Mercedes SL and BMW 6 Series. It will be built on the frame of the next-generation LS sedan, and Automobile says internal combustion motivation will come in three flavors. The starter will be a juiced-up version of the company's 5.0-liter, naturally aspirated V8, the one that currently makes 467 horsepower in the RC F. Stepping up from there will be some kind of hybrid powertrain good for around 500 horsepower; last year Motor Trend wrote that the hybrid would be based around a V6 ICE with Toyota's coming "multi-hybrid" system. The top step will be a twin-turbo version of the V8 that could exceed 600 hp. Early reports of dimensions have it at 185 inches long, 75 inches wide, and 53 inches tall. It is expected to use the world's first application of a ten-speed automatic transmission. It'll also get the RC F's torque vectoring mechanism for the rear-wheel-drive setup, though Car and Driver says an all-wheel drive option "might be added later." Aluminum and carbon fiber components will help manage weight. Its design will be inspired by the LF-LC concept, and right now its pricing is as murky as its looks. C/D posits an MSRP from $80,000 to $95,000, Automobile figures it will go "past the $100,000 mark," and MT pegs the situation at $150,000. All agree, however, that it will join the retail pipeline as a 2017 model.
