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.

Recharge Wrap-up: 1M Lexus hybrids, Best Buy Geekmobile goes Prius

Cummins is developing a plug-in hybrid system for heavy trucks. Its plug-in system for Class 6 trucks (those with a gross vehicle weight between 19,000 and 26,000 pounds) is expected to improve fuel economy by 50 percent. Funded in part by a $4.5-million grant from the US Department of Energy (DOE), the system will use a battery pack and some form of range extending internal combustion engine. The system will employ various drive cycles in order to help commercial fleets save fuel based on their needs. Read more at Gas2. German automaker Borgward, LG Chem, Bosch, and software firm SAP have joined forces to form an electric mobility partnership. Borgward recently revived its brand with a new model, the BX7. Borgward has also announced that two other models, the BX5 and BX6, will be available as plug-in hybrids. SAP will provide software services, and LG Chem will supply battery technology to Borgward. Bosch will supply and help develop a number of components for Borgward cars. Read more at Inside EVs. Lexus has sold its millionth hybrid. The luxury automaker began selling hybrids with the electrified RX in 2005, and the millionth hybrid was a NX 300h sold to a customer in Milan, Italy. "This is my first Lexus," says the customer of that vehicle in a Lexus release, Aldo Pirronello. "... and I am honored to celebrate this important milestone with Lexus!" Lexus currently sells 10 hybrid models worldwide. Read more from Lexus. Best Buy's Geek Squad is switching from Volkswagen Beetle Geekmobiles to the Toyota Prius C. As part of an update to the home electronics chain's house call service, the Geeks will be driving more eco-friendly cars with a refreshed logo. More than 1,000 Prius C Geekmobiles are being deployed nationwide. With the Geek Squad answering more than 5 million house calls a year, the fuel savings from switching to a more efficient hybrid cars means reduced emissions over the 12.6 million miles they'll drive per year. Read more in the press release below. Vehicle of Choice for Geeks? Toyota Prius c An armada of agents is about to roll out in Toyota Prius c. Their mission: to help people across America get the most from their technology. Starting today, Best Buy's Geek Squad will dispatch more than 1,000 of the vehicles – fully decked out as the new Geekmobile – nationwide.

Toyota struggling in Latin American market, attempting recovery

With uncertainty in the US and Chinese markets, automakers are scrambling to rev up their efforts in what were traditionally secondary markets. Take Toyota's efforts in Latin America. A recent story from The Wall Street Journal highlights the Japanese brand's push in the southern hemisphere, particularly in Brazil, where it has expanded its operations and installed new executives with a greater range of powers, all in a bid to grab a bigger slice of the ever-growing South American pie.
South America is dominated by General Motors, Fiat and Volkswagen, which maintain a combined 60 percent of the market share - Toyota holds a mere 4.5 percent. The WSJ spoke with Steve St. Angelo, Toyota's boss in Latin America, who said, "We are playing catch up, but we're catching up fast. We now have the resources to give the region the attention it really needs and deserves."
That attention includes an all-new, locally produced small car called the Etios. As bewildering as it seems, Toyota wasn't competing in the low-cost economy car market in South America. With the Etios, which arrived in September of 2012, its sales in the first seven months of 2013 are up 75 percent.
