Toyota maintains world's largest automaker crown, GM and VW close behind

Toyota still holds the title of World's Largest Automaker. The Japanese automaker ceded the claim to General Motors in 2011 following a series of natural and man-made disasters that stifled production in Asia. Production is back up to full speed and, coupled with the introduction of a new Camry midsize sedan, Toyota retook the title in 2012 and has so far been able to keep it by selling 2.43 million vehicles in the first quarter of 2013.
The race is still tight - General Motors reports sales of 2.36 million vehicles, earning it the second spot globally with Volkswagen's 2.27 million sales nabbing the German automaker third place. It's not all smooth sailing for Toyota, either, as the brand's first-quarter figures were down 2.2 percent when compared to last year. GM posted a 3.6-percent gain and VW managed a 5.1-percent gain over the same period.
Sales in China may be a deciding factor as to which automaker performs best in 2013. Toyota's figures were down 13 percent in China. Meanwhile, GM and VW are continuing their upward trajectories in the crucial Chinese market.

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.
