Mini Minor to be co-developed with Toyota

It was back in 2011 when Mini first showcased the prospect of an even smaller hatchback with the Rocketman concept at the Geneva Motor Show. In the nearly four years since, parent company BMW has hemmed and hawed on the possibility of putting it into production, but the latest word from Europe has it that the project is a go. According to Automobile magazine, Mini is realigning its product portfolio into five pillars: the essential hardtop we've already seen (available in two/three- and four/five-doors), the convertible, the upcoming new Clubman wagon (coming this summer with full-size auxiliary suicide doors on both sides), the next-gen Countryman crossover in 2016 and two new model lines. One will be the production version of the Superleggera roadster concept, earmarked for 2018. The other will be the Minor, a smaller city car reviving a long-gone model name and presaged by the aforementioned Rocketman concept. But for that last one, Mini won't go it alone. To develop the mini Mini, BMW will reportedly turn to its partnership with Toyota. The relationship is already set to yield a new Supra and Z4 and share fuel cell and other technologies. But this would broaden the partnership to include a small hatchback. However rather than use the existing (or next-gen) Aygo, which is already built under joint venture with PSA Peugeot Citroen (with which BMW previously had a joint engine venture), word has it that the BMW and Toyota will develop a new platform for the project – one that will be used by both partners. The new product plan doesn't leave much room for the Mini Coupe and Roadster (which have already been discontinued), for the Paceman three-door crossover (which will suffer the same fate) or for the projected seven-seater minivan. But the addition of the new Superleggera roadster and super-mini Mini aren't likely to leave us wanting for either. Related Video:

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.

10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.
