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.

Fuel cells will flop outside Japan, says VW

"It may fly within Japan, but not globally," VW's Shoji said.
It's long been battered into our beleaguered auto writer brains that the ultimate future source of motivation for tomorrow's cars and trucks is not gasoline, diesel, electricity, natural gas, propane or solar power - it's the hydrogen fuel cell. It's been the Next Big Thing since the start of Next Big Things.

Russian videographer nails this real-life 'Need for Speed' recreation

Aaron Paul and Kid Cudi tried. They really did. They put forth a decent acting effort, played with some incredible replica supercars, and filmed at some remarkable settings. But it's 2019, and 2014's "Need for Speed" sits at a 6.5/10 on IMDB, a 39 on Metacritic, and a 57% audience score on Rotten Tomatoes. The studio attempt to bring "Need for Speed" to life was lukewarm, so a Russian videographer took a shot at the idea with this impressive digital short. Unearthed by Reddit user, AbuDab1, the clip is the work of Russia-based videographer @Chekunov_v. Clearly a fan of all things fast and fancy, as seen by his Instagram, Chekunov recreated the start screen, the garage with car and mod selection, and the race sequences from the video game. The video starts with an Acura RSX Type-S (labeled as the Integra Type R) with familiar theme music playing in the background. Accompanied by video game sound effects, the spotlight switches between a Toyota Celica, a Toyota Supra and a Mitsubishi Lancer Evo. The Supra and Evo are locked, so the user settles on the Celica. He goes on to select mods, including a new spoiler, new wheels and a new color, again to the tune of the proper sound effects, menus and camera views. The car exits the garage and rolls onto the road, where the screen now shows a tachometer and an N2O gauge. The Celica is met with a race challenge, and the car lines up with a Mazda RX-8, an Acura RSX Type-S and a Subaru WRX STI. After a terrible launch, the Celica uses some NOS and takes the victory. Unfortunately, the video is a bit 2 fast, 2 short for our taste. It's well done, has some unique video work, and takes us back into one of our favorite video game series. Maybe this guy can direct the studio sequel.
