Customers want wireless charging in next-gen Prius Plug-In; they might get it

Could 2016 be the year prospective Toyota Prius Plug-in Hybrid buyers are waiting for? Why, yes, says an unidentified Toyota spokesman. That's according to Plug-in Cars, which reports that a wireless plug-in vehicle charging system may be less than two years away for the Prius Plug-in. WiTricity has, for a few years, been developing its magnetic resonance wireless charging system for the model. This type of system allows for more distance leeway than other wireless setups when it comes to how close the car and its on-board receiver need to be to the floor-mounted system. That allows for smaller, lighter on-board receivers, which is key for any plug-in vehicle. Toyota spokeswoman Jana Hartline confirmed in an e-mail to AutoblogGreen that the company has conducted wireless charging tests in Japan "with hopes to bring that technology to market in the near future" but declined to provide more detail on the company's plans to offer wireless charging for plug-ins. Toyota's Satoshi Ogiso said last summer that the Prius Plug-in would eventually offer a wireless charging system in response to prospective customers' demand for it, though he wasn't specific on a time frame. Toyota started discussions with WiTricity regarding wireless charging system development more than three years ago and said late last year that it had reached a licensing agreement with the Boston-based company. WiTricity has also worked on developing wireless-charging systems that are compatible with Audi and Mitsubishi vehicles. WiTricity grew out of MIT back in 2007, back when we could barely imagine how it would work.

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 still wants Tesla's battery help, still evaluating RAV4 EV program

Tesla Motors said earlier this month that the agreement it has with Toyota to supply battery packs for the Toyota RAV4 EV SUV would be finished by the end of the year. The deal is done, but Toyota is now singing its best version of Baby, Please Don't Go. The Japanese automaker may look to extend the battery-pack agreement with California-based Tesla, Automotive News says, citing comments made by Osamu Nagata, who heads Toyota's manufacturing and engineering in North America. Nagata also complimented Tesla for its "clear business strategy." Toyota, which owns 2.5 percent of Tesla, started the RAV4 EV collaboration in 2012, in which Tesla was to make about 2,600 battery packs for the all-electric SUV. That agreement was estimated to be worth about $100 million. "We are also evaluating the RAV4 EV program and will have more to say at a later date" – Toyota "We have a good relationship with Tesla and will evaluate the feasibility of working together on future projects," Toyota said in a statement e-mailed to AutoblogGreen. "We are also evaluating the RAV4 EV program and will have more to say at a later date." And while Toyota hasn't quite met initial sales expectations – it sold about 1,600 of the RAV4 EVs through this spring – the company expects to reach 2,500 by the end of the year. And the partnership did generate about $15 million in revenue for Tesla, according to that company's first-quarter letter to shareholders. That said, Tesla is obviously focusing its battery-making efforts on its own models.
