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 prices TRD Pro Tacoma, 4Runner

Toyota is finally all set to drop more details about the upcoming off-road ready TRD Pro Series models of the 4Runner, Tacoma and Tundra after first revealing them in February. These trucks and SUV might not get the big engine and other mods that desert-stormers like the Ford F-150 Raptor have, but they are still a nice step up over the stock versions. All of the TRD Pro vehicles come as 4x4 models with Bilstein shocks with remote reservoirs in the rear, TRD front springs, skid plates, black wheels, retro-inspired "TOYOTA" badging and TRD-branded floor mats and shift knobs on the inside. They're available in three colors: Inferno, Attitude Black Metallic and Super White.
The Tacoma hits the market first in early August with prices starting at $35,525, plus $885 for delivery, processing, and handling, for an Access Cab V6 with a six-speed manual. Opting for a five-speed automatic brings things up to $37,390 after the destination fee. A Double Cab with a manual goes for $37,320, or $38,300 for the automatic, after the delivery charges. The 4Runner follows in September with just a single trim priced at $41,110 - $41,995 after the charge - for the V6 and five-speed auto.
Toyota is holding off on revealing more about the Tundra for now. It's coming in the fall, but the company isn't announcing prices yet. We don't have to wait long, though. "Within the next month we'll reveal that," said Toyota spokesperson Sam Butto to Autoblog about the TRD Pro Tundra's price.

Hi-po Toyota GT86 to get KERS?

We happen to like the Toyota GT86 - and, it of course goes without saying that the same applies to the Subaru BRZ and Scion FR-S, as well - just the way it is. Yes, that includes the standard 2.0-liter four-cylinder boxer engine and its 200 horsepower at 7,000 rpm.
That said, a little extra power never hurt anybody, right?
The most obvious way to add some punch to the GT86 would be with a turbocharger, and that has indeed long been rumored for an STI version of the BRZ. Will Toyota follow suit? According to Top Gear, the answer is no. Says GT86 chief engineer Tetsuya Tada, "I think 300bhp with a turbo and 200g/km of CO2 would be tasteless in this day and age. And a turbo would mean the loss of the GT86's uniqueness." Perhaps a bit harsh, but there you go.
