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 reveals new versions of FT-1 concept at Pebble Beach [w/video]

Toyota certainly caught our attention when it unveiled the FT-1 concept at the Detroit Auto Show last January. Coming from the same people who gave us the Lexus LFA, Scion FR-S and Toyota Supra, the FT-1 concept looked striking in its bright red livery. But the Japanese automaker isn't quite done with it yet.
No, we're afraid we don't have a production announcement to share at the moment, but Toyota has revealed two new versions of the FT-1 concept that cast it in different light. Most notable is the graphite version pictured above. Replacing the bright red paintjob and two-tone red and black interior of the original concept, this second iteration - presented in the metal at McCall's Motorworks Revival in Monterey, California - goes for a more upscale and refined graphite exterior and a tan leather interior with exposed metal elements.
Both versions of the virtually road-going FT-1 concept will be playable in GT6, but at the same time Toyota also revealed (in digital form, at least) a virtual racing version of the concept called the FT-1 Vision Gran Turismo. Looking like the original concept was prepared for Japan's Super GT series, the FT-1 Vision GT is retuned for racing, with wider fenders, more extreme aero, competition-spec alloys on slicks and the like.

Scion pondering move upmarket?

Scion is simultaneously celebrating its ten-year anniversary with the 10 Series models and trying to figure out what to do with itself over the next ten years. Once a go-to consideration for young, first-time buyers who wanted something cool and different, in 2013 it has a model everyone is still talking about in the FR-S, a model few are still talking about in the iQ, and three models in between in the tC, xB and xD that make everyone wonder, "What happened?"
Automotive News spoke to Toyota's North American CEO, Jim Lentz - he was the VP in charge of Scion when it launched - about the options, and Lentz said one of them could be a move upmarket to challenge the established luxury brands that are moving downmarket. "There's going to be a big need in the $25,000 range for a fun-to-drive, nice-looking, value-oriented product," he said, and the FR-S, which starts at $25,255, could provide the platform for Scion to climb up a notch or two in price and perception. An idea like this could conceivably work in tandem with a proposal to move entry-level Scion products over to the Toyota brand - but remember, this is all just ideas on a whiteboard at the moment.
As opposed to an "entry-luxury fighter," the brand could swing back to the other option that was considered when it was formed, directly challenging the Korean makes that have usurped its cachet with first-time buyers. Lentz said Scion could go either way, and the tone of the piece seems to indicate that the final direction is still a ways away from being resolved.
