Toyota's Euro Aygo spied in prototype form

The five-door version of the next-generation Toyota Aygo, a Euro offering cloned by the Peugeot 107 and Citroën C1, has been caught out on the town wearing all black. Facelifted early last year, predictions are that the next version of the city car will be slightly lower and wider than the current car, with improved ergonomics and materials. Based on what little can be seen for now, a new intake and headlight treatment should be on the menu in front, with taillights placed higher on its backside.
A three-door version is expected, but a gasoline-hybrid model is also rumored, along with power and fuel economy improvements to the three-cylinder engine that presently puts out 67 horsepower and 69 pound-feet of torque.
We should see it next year, along with the new Citroën C1 and Peugeot 108.

Former NHTSA chief may lead automaker-backed Takata investigation

An automaker-led effort may see the former head of the National Highway Traffic Safety Administration take on the probe into the Takata airbag inflator disaster. A coalition of at least ten automakers is in talks with former NHTSA administrator David Kelly, with unnamed sources familiar with the discussions telling The Wall Street Journal he is "among those we are considering to coordinate" the investigation.The Detroit News, meanwhile, is reporting he could be hired "in the coming days." Takata, the Japanese seatbelt and airbag manufacturer, has been the center of a defect scandal since last year. Takata is under fire for air bag inflators that can explode, shooting out metal and plastic pieces. At least five deaths and dozens of injuries have been linked to the problem worldwide. Earlier this year, Honda Motor Co., the automaker with the biggest exposure to the defective Takata air bags, was fined $70 million in the U.S. for not reporting to regulators some 1,729 complaints that its vehicles caused deaths and injuries, and for not reporting warranty claims. It was the largest civil penalty levied against an automaker. Should he take the role, Kelly would be at the fore of an investigation being assembled by an alliance of ten automakers, which includes the Detroit Three and Honda. Toyota first suggested a joint investigation back in December, The Journal reports. Kelly's goals, meanwhile, will be many. The Detroit News reports that questions abound regarding not only the recalled airbag inflators and the conditions that cause them to fail, but the whether the replacement units will have similar problems in the future. The automaker committee is far from the only one analyzing the airbag issue. Takata has assembled its own panel, led by former Secretary of Transportation Samuel Skinner, while NHTSA's deputy administrator, David Friedman, has brought in an outside engineering firm to investigate the inflators, The Detroit News reports. Separately, on Friday Takata Corp., the Japanese seatbelt and air-bag maker at the center of a defect scandal, is expecting more red ink for the fiscal year through March. It is projecting a 31 billion yen ($264 million) loss, worse than the previous forecast for a 25 billion yen ($214 million) loss, despite higher sales expected for the fiscal year. Ten automakers have recalled about 12 million vehicles in the U.S. and about 19 million globally for problems with the air bags.

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.
