2014 Toyota Tundra to debut at Chicago Auto Show

The fullsize pickup market is dominated by trucks from Ford, General Motors and Ram, but this segment could get some hefty competition in coming years. We've already reported that Nissan is planning a redesign of its Titan truck for 2015, and now Toyota has announced that it will be revealing the 2014 Tundra next month at the Chicago Auto Show.
In the brief press release posted below, Toyota says that the 2014 Tundra will be "redesigned," but it's unclear as to whether this means we'll be seeing an all-new truck or just an extensive refresh. The current Tundra design has been around since 2007 and sales are hardly worrisome to the Big Three, so a new design would be a logical guess.
In any case, we only have to wait a couple more weeks for the new Tundra to debut on February 7, and we'll be on hand to bring you plenty of live coverage from the show.

BMW-Toyota sports car heading towards Tokyo debut

Earlier this year, BMW and Toyota confirmed a four-part joint venture mostly focusing on increasing improving vehicle efficiency using fuel cells, lightweight materials and better battery technology. Also tucked into the announcement was a "feasibility study" for a shared platform to underpin a future midsize "sports vehicle."
In terms of the latter, it seems that things have stepped up from the feasibility stage to the conceptual stage, as Motor Trend reports we could see a pair of new sports car concepts debut later this year in at the Tokyo Motor Show. There isn't much information about the new program, but the article suggests the sports cars could be all-wheel drive hybrids, with electric motors powering the front wheels and a gas engine powering the rear wheels. While a partnership between Toyota and BMW might not lend itself to a catchy portmanteau like "Toyobaru," here's hoping it will bear fruit that is as exciting as the ones produced by the Toyota/Subaru tie up.

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.
