Toyota buys Daihatsu for small-car development

Toyota is getting serious about small cars, but it's not going at it alone. Instead it's turning to its subsidiary Daihatsu, with which it will now share more resources and expertise. And in the process, it's acquiring the remaining stake in the smaller automaker. Daihatsu is a Japanese carmaker founded in its present form in 1951, but with roots that trace back as far as 1907. Toyota acquired a controlling interest of 51 percent in Daihatsu in 1988, bringing the company under its umbrella. But now it is raising its stake to 100 percent by a reciprocal share-swap agreement that will see Daihatsu's other shareholders take 0.27 shares in the larger company for each share in the smaller. As part of the new arrangement, the Daihatsu division will take the lead in developing new small cars, both for itself and for its parent company. Toyota in turn will also share key technologies with Daihatsu, and both will share each other's networks in emerging markets. The bottom line is that we can expect to see more small Toyotas and Scions developed and built by Daihatsu in the near future. The Daihatsu name may not be as familiar to Americans as some of Toyota's other brands. It briefly sold models like the Charade and Rocky in the United States under its own name in the late 1980s and early 90s. However US customers may be more familiar with those it built for the Scion brand, such as the Scion xB that was based on the Daihatsu Materia. While the realistic part of our brains force us to admit it's unlikely, the dreamer within us will hold out hope that the new arrangement could see a Scion version of the nimble little Daihatsu Kopen roadster make its way to our shores in the coming years. Toyota and Daihatsu to Strengthen Small Car Operations through Unified Global Strategy Toyota Motor Corporation (Toyota) and its subsidiary Daihatsu Motor Co., Ltd. (Daihatsu) have reached an agreement whereby Daihatsu will become a wholly-owned subsidiary of Toyota by way of a share exchange (expected to be completed in August 2016). The purpose of the agreement is to develop of ever-better cars by adopting a unified strategy for the small car segment, under which both companies will be free to focus on their core competencies. Ultimately, this will help Daihatsu and Toyota to attain their joint goal of achieving sustainable growth. Additionally, the aim of the share exchange is to enhance the value of both brands.

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. Read more in the press release below. 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.

How platform problems are delaying next-gen Prius

Short-term pain for longer-term gain? That may be the prognosis for the next-generation Toyota Prius, the world's best-selling hybrid. But, hey, the new version might get holiday season debut, now. Toyota is upgrading some of its most popular models and trying to cut long-term costs with components that can be used on multiple models on the new Toyota New Global Architecture platform, Automotive News says. That means more parts that can be used for the Camry, Avalon (not big stretch, since the Avalon is basically a rich man's Camry) and Corolla in addition to the Prius. The downside, of course, is that this takes a bit more engineering and certainly more time. In the case of the Prius, that means pushing back the start of production from next summer to December 2015. But Automotive News also says the Prius may have an all-wheel-drive option. Happy Holidays. The report is in update from Automotive News Europe, which cited folks familiar with the process who were not identified and said late last month that the production of the fourth-gen Prius would be pushed back by about six months as engineers continue to tweak the hybrid powertrain for maximum efficiency. The goal is around a 10 percent improvement in fuel-efficiency thanks to an upgraded powertrain and lower vehicle weight. Toyota spokeswoman Amanda Rice told AutoblogGreen in an email that the company doesn't comment on future products, so we'll just have to keep an eye out.
