Dubai claims debut of Toyota GT86 sedan concept

Typically, when the organizers of an auto show reveal that a new car will debut at their show, we take notice. But this particular claim from the Dubai International Motor Show ought to be taken with a grain of salt.
As our compatriots at AutoGuide discovered, the Facebook page for the Emirates auto expo includes a post with an interesting claim: that a sedan based on the Toyota GT86 (known in the US as the Scion FR-S) will debut at the show. The Facebook post is accompanied by the image above, purporting to show the concept in question.
The strange part is that the organizers claim the four-door GT86 concept will make its "regional unveil" at the Dubai show, which would seem to indicate that the concept in question would make its international debut at an earlier show. Considering that the doors open in Dubai on Tuesday, that seems increasingly unlikely. All of this begs the question, If this isn't actually a four-door GT86, what might it be?

When a Ferrari and a Toyota GT86 get jiggy, strange things happen

Swapping V8s into small Japanese cars is not new. In fact, swapping V8s into small sportscars from anywhere is not new. From the original Cobra to the modern FR-S and BRZ, big V8 power in a light, lithe chassis has been delicious combination rivaling the Reese's peanut butter cup. People familiar with these swaps know that American iron is the preferred source for large-displacement grunt, but Ryan Tuerck and Gumout have taken a different route, specifically from Italy. Replacing the 2.0-liter flat-4 of this Toyota GT86 is a Ferrari F136 V8. Unfortunately that's about the only detail we really know about this project. The F136 was used in the F430, California and 458 Italia, and all with varying displacement and output. So we don't even know which of those variants this engine is. If it came from a California, that'd at least make the front-engine location easier to fabricate. No matter though, it's still a Ferrari engine in a small car, and that's awesome. And Donut Media, the company that produced the video, promises more details down the road. In the meantime, enjoy this video preview of the project.

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. Read more in the press release below. 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.
