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.

Ford barely edges surging Chrysler for Canadian sales crown in best year ever

The auto industry in the US showed strong results through much of 2014 with sales regularly growing year-over-year for many brands. That same trend carried over in the Great White North, as well. Canada posted its best numbers ever with 1.85 million units sold, up about 100,000 vehicles over 2013. The country nearly had a new market leader, too. The big winner among our neighbors to the north in 2014 was Ford with 291,951 vehicles sold, up 3 percent from 2013, according to Reuters. That success also handed the company the sales crown for the fifth consecutive year. In large part, the strong result came from the company's popular trucks, which represented about 80 percent of overall sales. "Ford moved into the number one position in September and didn't look back," said a note to clients by DesRosiers Automotive Consultants quoted by Reuters. However, the Blue Oval didn't exactly take an overwhelming lead for the year. The company nearly had to hand over the sales trophy to FCA after the company rallied in the latter part of the year. The Italian-American conglomerate had its best results ever to nip at the Ford's heels and move 290,004 units for 2014, a 12-percent improvement from last year. Jeep especially helped the bottom line with over 50-percent growth, according to Reuters. Only two other brands were able to break the 200,000-vehicle barrier in Canada for 2014. General Motors came in third place overall with 249,800 sales, up 6.3 percent. The combined Toyota and Lexus also barely jumped the hurdle with 200,851 units moved, a 2.8 percent improvement.

BMW i5 could get Toyota-sourced hydrogen power

It's starting to feel like the automotive landscape is right on the cusp of a boom in hydrogen-fueled vehicles. After all, the Toyota FCV is nearly ready, Volkswagen is readying a fuel cell concept for this week's Los Angeles Auto Show and Hyundai already sells its Tucson Fuel Cell. The next big name to add to that list might be BMW, as the company's co-development deal with Toyota starts to bear fruit.
According to Autocar, BMW may use a version of the fuel cell system from the Toyota FCV in the future i5. As part of its eco-oriented i sub-brand, the i5 is expected to be a stretched version of the i3 (pictured above) with extra rear legroom and cargo space. It's unclear at the moment whether a battery-powered pure electric powertrain will also be available. If accurate, then the rumor could give the Bavarian brand a counterattack against Mercedes-Benz' planned fuel cell vehicle in 2017.
BMW and Toyota first signed the memorandum of understanding to co-develop fuel cells, lightweight technology and a sports car back in 2012, and they made the arrangement official in late 2013. So far, few details on the progress of the work have been disclosed, but the performance model has been rumored to use a front-engine, all-wheel drive layout with supercapacitors.
