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.

Cosworth announces Power Packages for Subaru BRZ, Scion FR-S with up to 380 hp [w/video]

Cosworth stands on the list of the most famous engine tuners in the world with its DFV engine engine dominating Formula One for a time in the '70s. So when it teases plans to take on the FA20 engine from Subaru and Toyota found in the BRZ, Scion FR-S and Toyota GT86 abroad, our interest is indeed piqued. Cosworth is promising to take the 2.0-liter, four-cylinder boxer engine from its current 200 horsepower all the way to 325 hp and even 380 hp in a future track version through a series of staged Power Packages. At the moment, only the first stage is available that takes the mill to a potent 230 hp.
Cosworth says that its new strategy is to offer its upgrades in kits rather than individually so that it can be sure that everything works and fits when owners receive it. The Stage 1 Power Package emphasizes helping the FA20 breathe better and includes a nearly complete replacement for the stock exhaust system. There is a sports exhaust with four-inch, diagonally cut, polished tips and Y-shaped muffler, an overpipe front pipe with a spherical resonator and a new manifold header that is 22 percent lighter the standard unit. In addition to that, the kit comes with a software reflash, low temperature thermostat, Cosworth badge and plaque.
The stage one kit is available now, and stages two and three go on sale later this summer, according to its website. Autoblog contacted Cosworth for pricing information for the kits. We will update this story, if we hear back. The company also released a video showing off the exhaust upgrades. Scroll down to watch it and read the full release, below.

Toyota SEMA concepts promote active lifestyles, rallying [w/video]

Toyota has six vehicles that it's bringing to the Specialty
Equipment Market Association (SEMA) show next week, all of which were developed by and for people who live active lifstyles. Four of them are the result of the Toyota Dream Build Challenge, which tasked a team of athletes and vehicle customization shops to build Toyota sedans, pickup trucks and sport utility vehicles in seven weeks that would enhance performance in their respective sports.
We'll lead off with the CamRally Camry, developed by NASCAR driver Parker Kligerman, Kyle Busch Motorsports and Mooresville, NC shop Detroit Speed, Inc. for the Dream Build Challenge, because it appeals to us gearheads (sure, call us one-sided). It was totally transformed into a rally vehicle, and it has to be the most badass Camry we can remember seeing. The sedan is always a bit flaccid-looking in stock form, but the CamRally's wide body and other exterior upgrades and the turbocharger make us forget about that, as do its stripped, painted interior and Sparco race seat.
