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.

TMG's super Lexus LS Sports 650 gets track tested

The people at Toyota Motorsport GmbH have been responsible for the Japanese automaker's motorsports efforts since the 1970s, but since Toyota pulled out of Formula One after the 2009 season, the tuning shop has been developing a super sedan based on the Lexus LS called the Sports 650. Details on TMG's first road car have been scarce, but XCAR was recently invited to drive the 641-horsepower Lexus on track.
Here's what we know: the Sports 650 has enough power to sprint to 60 miles per hour in under four seconds, tops out at 199 mph, weighs over two tons and utilizes LFA brakes. Oh, and its twin-turbo V8 bellows like an AMG V8. That last part isn't surprising when considering TMG could become Toyota's in-house tuning arm - like AMG is to Mercedes-Benz. As for the bespoke body kit, fender flares and stacked exhaust pipes? They fit the car well and even remind us a bit of Lexus' other high-performance sedan, the IS F. Currently there are no plans for the Sports 650 to be made into a production car, but we doubt TMG is devoting this much effort developing the LS into a road-rocket for nothing.
Check out XCAR's video below to see the AMG-fighter wrung out on track, and then ponder what could be if TMG were let loose to fiddle with other cars in Lexus' lineup. Now that's something we could get used to!
