Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

2015 Toyota Camry priced at $22,970*, Hybrid at $26,790*

We last saw the heavily revised 2015 Toyota Camry at the New York Auto Show earlier this year. Now, it's finally time for the best-selling car in the US to hit the roads in late September, and Toyota is announcing how much the updated model actually costs.
The basic Camry LE rings up for $22,970 (*not including a $825 delivery, processing and handling fee). That's up slightly from the base price of $22,425 for the 2014.5 LE, but the updated sedan has some 2,000 new parts, while also being 1.8 inches longer and boasting a 0.4-inch wider track. The rest of the trim levels include the SE for $23,840, sporty new XSE for $26,150 and XLE at $26,150. Opting for the V6 is the XSE and XLE bumps pricing to $31,370.
Separately, the Camry Hybrid gets its own LE, SE and XLE trims. The LE starts at $26,790 with a standard, power driver's seat and 4.2-inch information display. The SE for $27,995 gets an improved interior and the XLE at $29,980 has leather, heated front seats, LED running lights and more.

Toyota preparing Scion-badged Nissan Juke fighter

As we've said on multiple occasions, the sub-compact crossover market is The Next Big Thing™. With that in mind, Toyota's lack of a competitor to the new breed of super-small, super-cute crossovers like the Nissan Juke, Honda HR-V, Mazda CX-3, and Jeep Renegade has been especially glaring. But as these photos show, the hole in the Japanese giant's lineup could soon be filled. Our spies captured this heavily disguised prototype testing in the deserts of the American southwest, signaling that Toyota is preparing to wade into the Nissan Juke's space by offering a tiny, but very heavily styled crossover of its own. Our spy photographers call the cute ute's look "aggressive," citing inspiration from the Toyota C-HR concept from the 2014 Paris Motor Show. Based on the meaty wheels and tires and what we can see through the camo, we're inclined to agree with their assessment. Underneath that sheet metal, we're told the new car rides on Toyota's new NGA platform. Like the Juke, a four-cylinder engine and continuously variable transmission will be on offer, although there's no telling whether Toyota will follow its rival's enthusiast beat and offer a six-speed manual version. What we find most interesting about all of this conjecture, though, is what it means for Scion, rather than its parent. Introducing a small crossover is the next logical step for Toyota's troubled sub-brand, and would serve as a delectable followup to the recently released iA sedan and iM hatch. Such a three-model lineup, when combined with the enthusiast-oriented FR-S, would transform Scion into a force to be reckoned with in the entry level space. Supporting this conjecture isn't too hard, either. As the spy photos show, this camo'd tester is being supported by a xB, the closest thing Scion (or its parent company, for that matter) have to a sub-compact CUV. It's unclear just when this new model will make its debut, but if Toyota hopes to make inroads into this popular new segment, this CUV will need to arrive before its extremely competent rivals can establish a solid foothold.
