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.

The revolutionary Bose suspension that could have been

The Bose name pops up on these pages every once in a while – usually, as you might expect, because some automaker or another has installed its audio systems in one or more of its models. But a few years back, the research-driven audiophiles at Bose developed a revolutionary adaptive suspension system that could have been a game-changer. Sadly, it wasn't. The Bose suspension system was a technological breakthrough. As you can see from the pair of Lexus LS sedans demonstrated (and the Porsche Cayman thrown in for good measure) in the two-minute video above from CNET, the system virtually eliminated body roll and smoothed out bumps in the road to near glass-like serenity. It could even jump over minor obstacles. Unfortunately, the system was too heavy and expensive to put into production, and the project was shelved. Instead, it was repackaged into a suspended driver's seat for heavy-duty, long-haul trucks and called the Bose Ride System. It's said to significantly reduce fatigue and back pain while encouraging driver alertness and wellness – which is all well and fine, but a far cry from what the suspension system could have meant for the automotive industry. Just think about that the next time you notice the Bose logo on the speaker grille in an upscale vehicle from the likes of Audi, FCA, GM, Mazda, or Nissan – all automakers that offer Bose audio systems, and which might have considered implementing the advanced suspension if only it were more practical for production.

Lexus GX and LX future may be in doubt

With the debut of an all-new RX, Lexus is in a position for continued strong sales in the luxury SUV arena. The fourth-generation RX has grown, making room for the new NX model beneath it. But further up the ladder, things could change for the GX and LX. In an interview with Autoblog at the 2015 New York Auto Show, Lexus executive vice president Mark Templin gave some hints at the future of his brand's SUV lineup. "With NX and RX, we have a really good one-two punch in the crossover segments, and we think we can cover most of the markets with that," he said. As for the larger, three-row GX and LX models, which are built on a traditional ladder-frame chassis, things aren't so clear. Templin noted the the success of both models all over the world – the LX is the best-selling Lexus in Saudi Arabia. The same is true for sales here, he said: "We do very well with those products in the United States – GX has been a great product for us in the US for the last couple of years since its initial introduction. But the future of those vehicles longer term is in doubt because of regulations that are being driven by governments all over the world." Don't start stockpiling LX 570s in anticipation of shortages just yet. Templin didn't give any specifics; he just notes that tightening fuel economy and emissions regulations could affect product planning. In our analysis, if and when GX rides off into the sunset, Lexus still needs a midsize, three-row SUV to fill that gap. The most likely candidate for that is some variation on the RX. Whether or not that's the case, don't expect a BMW-like proliferation of body styles from Toyota's luxury division. "It creates problems. It creates complexity, that's hard for every step of the process," Templin said, nothing that too many models stresses the design department, manufacturing, and even dealers inventory selection. As for the bottom end of the lineup, Templin wouldn't comment on a compact SUV below the NX, saying "I think there are more potential options for us in the future, but we're not trying to grow the number of models we have in our lineup. It's not really what our core business is about." For now, Lexus and Templin are focused on launching the RX, which accounts for three of every 10 Lexus models ever sold. The 2016 model, available in RX 350 and RX 450h hybrid versions, goes on sale by the end of the year. Related Video:
