Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

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 U2 urban utility concept inspired by Maker Faire [w/video]

There's a quiet revolution happening in US cities. People want to mix an urban lifestyle with a connection to nature and appreciation for craftsmanship. The result of all of this is folks pursuing things as varied as urban farming, home brewing and the whole maker movement. Toyota thinks it has the perfect concept for these intrepid customers with its new Urban Utility concept that it is debuting during a panel discussion hosted by Make: magazine in San Francisco and debuting publicly on September 20 at the World Maker Faire in New York City.
The Urban Utility concept can best be described as a modern take on the old panel van. Designers from Toyota's Calty Design Research center in California interviewed Maker Faire participants to find out what its users want from a novel vehicle like this. "Toyota saw an opportunity for a new approach to an urban vehicle based on increasing re-urbanization of our cities and urban drivers' desire for flexibility, fun and maneuverability," said Kevin Hunter president of Calty.
On the outside, the Urban Utility doesn't really scream for attention. It's meant to meet users "desire for greater utility but a smaller vehicle footprint," according to the release, but the shape is still very much a van. The designers do try to lend it some panache with the LED headlights up front and checker board side panels. It's really more about utility than looks, though, because the roof can roll back for taller loads, the rear glass retracts into the tailgate, and the whole rear can fold down as a ramp to load stuff more easily into the cabin. Toyota isn't talking about a powertrain yet but claims that the underbody is also especially durable for a long life in the big city.
