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.

2014 Toyota Corolla gets marginal IIHS small overlap crash test score [w/video]

Toyota may have performed some major surgery on the 2014 Corolla, but that hasn't helped the Japanese automaker overcome tough new crash test procedures. The Corolla, Toyota's bread-and-butter compact sedan, managed only a Marginal score on the new small overlap crash test, which was just added last year.
Despite the low score, the Corolla performed well in the moderate overlap front, side, rollover and rear testing, which was enough to score it a 2013 Top Safety Pick. In testing in August, six of the Corolla's competitors earned the Top Safety Pick + award, for good or acceptable scores across the board.
According to the Insurance Institute for Highway Safety, the Corolla's "Marginal" score was down to an "intruding structure," that could cause injuries to the lower left leg. There was also concern that in a collision, the driver's head would move after hitting the air bag, and collide with the A-pillar or dash.

The UK votes for Brexit and it will impact automakers

It's the first morning after the United Kingdom voted for what's become known as Brexit – that is, to leave the European Union and its tariff-free internal market. Now begins a two-year process in which the UK will have to negotiate with the rest of the EU trading bloc, which is its largest export market, about many things. One of them may be tariffs, and that could severely impact any automaker that builds cars in the UK. This doesn't just mean companies that you think of as British, like Mini and Jaguar. Both of those automakers are owned by foreign companies, incidentally. Mini and Rolls-Royce are owned by BMW, Jaguar and Land Rover by Tata Motors of India, and Bentley by the VW Group. Many other automakers produce cars in the UK for sale within that country and also export to the EU. Tariffs could damage the profits of each of these companies, and perhaps cause them to shift manufacturing out of the UK, significantly damaging the country's resurgent manufacturing industry. Autonews Europe dug up some interesting numbers on that last point. Nissan, the country's second-largest auto producer, builds 475k or so cars in the UK but the vast majority are sent abroad. Toyota built 190k cars last year in Britain, of which 75 percent went to the EU and just 10 percent were sold in the country. Investors are skittish at the news. The value of the pound sterling has plummeted by 8 percent as of this writing, at one point yesterday reaching levels not seen since 1985. Shares at Tata Motors, which counts Jaguar and Land Rover as bright jewels in its portfolio, were off by nearly 12 percent according to Autonews Europe. So what happens next? No one's terribly sure, although the feeling seems to be that the jilted EU will impost tariffs of up to 10 percent on UK exports. It's likely that the UK will reciprocate, and thus it'll be more expensive to buy a European-made car in the UK. Both situations will likely negatively affect the country, as both production of new cars and sales to UK consumers will both fall. Evercore Automotive Research figures the combined damage will be roughly $9b in lost profits to automakers, and an as-of-yet unquantified impact on auto production jobs. Perhaps the EU's leaders in Brussels will be in a better mood in two years, and the process won't devolve into a trade war. In the immediate wake of the Brexit vote, though, the mood is grim, the EU leadership is angry, and investors are spooked.
