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.

Ford Fusion production scaled back just 3 months after it was accelerated

Three months after kicking off production of the Ford Fusion at its Flat Rock, MI factory, Ford Motor Company is taking steps to trim output in the face of heavily discounted competition from Toyota and a growing supply of vehicles.
The addition of Fusion production in Flat Rock - which also builds the Mustang - was meant to be what pushed the handsome mid-sizer past its arch-nemesis, the Toyota Camry. An extra facility building Fusions was also meant to curb the growing demand for Ford's highly profitable sedan.
But with word that Flat Rock would take "approximately" one extra week off for the holidays combined with an 88-day supply of Fusions - reportedly due in no small part to what Morgan Stanley analyst Adam Jonas called "aggressive discounting of the Camry" - some analysts are now beginning to wonder if Ford may have overextended itself by adding a second Fusion facility to the mix.

Watch the Muppets go for ice cream in a Toyota

Do Muppets drive? We're not sure it's necessarily a good idea, but it's been known to happen. Fozzy called his hibernating uncle's Studebaker a bear's "natural habitat," and Doctor Teeth wouldn't get the Electric Mayhem very far without his band's psychedelically painted school bus. But how about Rolf in a 2014 Toyota Highlander?
That's what we got a glimpse of in the run-up to the Super Bowl, and the same combination (plus one Rizzo the Rat) that features in this adorably ordinary video below. Ordinary because it's just a couple of guys going out for an ice cream. Adorable because, well... they're Muppets. See what we mean in the surprisingly entertaining two-minute clip below.
