Toyota recounts past Supra glories

It could just be a slow start to the news week around the Toyota offices, but its UK blog has posted a brief history on its legendary Supra sports car. Read into however you'd like, but there has been plenty of speculation as to the return of the Supra nameplate in recent years (including last month from incoming Toyota chairman Takeshi Uchiyamada).
Built from April 1978 through July 2002, Toyota's sports coupe made quite a name for itself as both the Celica Supra (shown above) and the Supra, and the blog post charts many of the changes and highlights through the years. Head on over to the Toyota UK blog to read more about this Supra's history, and then be sure to check out the gallery of images from Toyota spanning all four generations.

Recharge Wrap-up: Toyota to go electric with Aygo? Renault Zoe bests BEVs in e-Rallye Monte-Carlo

Toyota could sell the Aygo hatchback as an EV. Toyota Europe CEO Johan van Zyl says that the A-segment city car could be a candidate for all-electric power. "We see a stronger growth of that type of thinking in cities where they're saying, 'We'd rather have emissions-free vehicles so it should be a plug-in or a pure-electric vehicle,'" he says. As the Aygo is produced alongside and shares most components with the Peugeot 108 and Citroen C1, it's possible those cars could see a plug-in version in the future as well. Read more at Hybrid Cars. The Renault Zoe took first and second place in the battery electric category of the 2016 e-Rallye Monte-Carlo. Defending Renault's title for a third year, two of the updated Zoes with improved range topped the category, taking second and third place overall. A hydrogen powered Toyota Mirai bested the Renaults by taking first place overall. 34 crews entered the competition, which took them from Fontainebleau, France to Monaco over four days.

Tanha, who cohosts the TransMissions podcast, commissioned artist Brendan Cahill to sketch a comic book cover featuring the Tesla Model X as a Transformer. The result is the Voltic (a name borrowed from Grand Theft Auto 5), an impressively reimagined Tesla Transformer that launches missiles from its falcon wing doors. While it doesn't necessarily fit into IDW's Transformers storyline, the commissioned piece does capture the imagination of comic fans and Tesla enthusiasts alike. Read more at Teslarati. Singapore is launching an EV carsharing program. The nation's Economic Development Board and Land Transport Authority have commissioned Bollore Group's BlueSG to operate the fleet of 1,000 EVs and 2,000 charging points by 2020, with 125 cars and 250 charging points available by the middle of next year. The program – sort of similar to the BlueIndy program in Indianapolis – is part of an effort to reduce pollution. "The future of transport in Singapore will look very different from today," says Coordinating Minister for Infrastructure and Transport Khaw Boon Wan. "Most people will not see the need to own a car." Read more at Wards Auto.

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.
