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.

Toyota FCV rallies to the hydrogen cause as zero car

It's been two decades since Toyota dominated the World Rally Championship with its Celica Turbo 4WD. But this past weekend, Toyota hit the rally stage in a very different vehicle.
That, as you can see, is the Japanese automaker's Fuel Cell Vehicle (FCV), which is still in its prototype phase. We're still at least half a year away from seeing the FCV in production trim, but the model has already been pressed into duty as the "zero car" at the Shinshiro Rally, the last round of the Japanese Rally Championship.
The zero car, for those unfamiliar, is to rally what a pace or safety car is to circuit racing, driving the rally stage to check for signs of trouble before the competitors put their feet to the floor, so it's not as if the FCV needed extensive modifications. From the looks of things, it just needed some jazzy stripes, mud flaps, probably different rolling stock and an interior with racing buckets and harnesses, roll cage, radio equipment and maybe a bit more ground clearance.

2014 Toyota Tundra Platinum 4x4

The Toyota Tundra is the automotive version of off-brand Cheerios: it doesn't dominate the market, and it's not the first model people think of when they hear the term "pickup truck."
Ford, General Motors and Ram dominate the segment with vehicles that offer ridiculous levels of towing and payload capacities and models loaded with luxury items and primed with tech-rich engines. The off-brands, meanwhile, are led by the Tundra, which while still accounting for six-figure sales (112,732 units in 2013, up from 101,621 in 2012), sits well behind the F-150s and Silverados of the world. After our first drive of the revamped 2014 Tundra, we came away thinking this truck is a total underachiever, aimed at placating Toyota loyalists and doing little to win over new customers.
But everybody deserves a second chance, and we thought a week's drive in a different environment might lead to a different - or at least a more fully realized - opinion. While the Tundra might not be an industry leader, it still makes it on many truck buyers' shopping lists. So, should you consider this off-brand pickup truck? To find out, we borrowed a top-of-the-line Tundra Platinum for a week. Read on to see what we found.
