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.

US buyers show little interest in big hybrids

The idea of producing large, luxury-vehicle hybrids is turning into a "what were they thinking?" exercise in futility, USA Today reports. General Motors is discontinuing hybrid versions of the Cadillac Escalade, Chevrolet Tahoe and GMC Yukon SUVs, while Mercedes-Benz and Toyota's Lexus division are doing the same with their S-Class hybrid and LS hybrid sedans, respectively. The culprit? Big price increases for fuel economy improvements that border on the unimpressive. Granted, the Escalade hybrid gets 31 percent better fuel economy than the standard version, but that still maps out to a combined fuel-efficiency rating of just 21 miles per gallon. That can be seen as a worthwhile increase, if it didn't cost over $8,000 extra. The 2014 Escalade Hybrid, for example, starts at $74,425 while the non-hybrid can be had for $66,295. Meanwhile, the Lexus full-size hybrid costs $6,000 more than the regular version but only gets 1-2 mpg better combined fuel economy. The result of all these high costs? Low sales. Through April, GM sold 82 of its hybrid SUVs and pickups, down from 541 a year earlier. And the LS hybrid sales were in single-digit territory for April. That isn't stopping Lexus from promoting its hybrids as the right solution (with the wrong facts), though. There are still automakers giving big hybrid vehicles a shot, though. Nissan's Infiniti division is selling a hybrid version of its QX60 and says an impressive 10 percent of QX60 buyers choose the hybrid, which costs just $3,000 more. Looks like money talks.

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.
