Scion rules out roadster, turbo versions of FR-S

Ever since Toyota and Subaru released the sports car alternatively known as the GT86, 86, BRZ and Scion FR-S a couple of years ago, rumors have circulated that even more exciting variants could be in store. But at least as far as Scion is concerned, those rumors are apparently nothing more than wishful thinking. Speaking with WardsAuto at the LA Auto Show last week, Scion chief Doug Murtha said that the prospect of an FR-S roadster has been taken off the table entirely. Apparently Scion lobbied parent company Toyota to produce just such a model, but after failing to find other markets interested enough in the model to put it into production, corporate HQ said no. "I think we were pretty aggressive on our (submitted plan), but we looked at what we would have conceivably lost on the product and said, 'We're not going to even push it further,'" Murtha said, going on to note, "Nobody was more disappointed than we were." Murtha further shot down the idea of a turbo version of the FR-S, dismissing it as a prospect the blogosphere (that's us) wanted to happen but "that's not something that's coming." Either variant might have helped Scion and Toyota boost sales of the model (which are predictably dropping after their first two years on the market), but the investment also might not have paid off their development, tooling and marketing costs. Of course, Murtha can only speak for Toyota, but we'd be surprised to see Subaru go it alone on either model, as costs would be that much more prohibitive without a partner. Bummer.

FIA introduces 'Hypercar Concept' for World Endurance Championship

One of the most common jabs at hypercars is the question, "Where can you drive them to their potential?" Imagine the answer being: to the checkered flag in the 24 Hours of Le Mans. We're not there yet, but the FIA World Motor Sport Council took a step closer to the possibility during its second annual meeting in Manila, the Philippines. One of three initiatives the WSMC announced for the 2020 World Endurance Championship was "Freedom of design for brands based on a 'Hypercar' concept." This "Hypercar concept" would replace LMP1 as the premier class in the WEC. The dream, of course, would be seeing racing versions of the AMG Project One, Aston Martin Valkyrie AMR Pro, Bugatti Chiron, Koenigsegg Regera, McLaren Senna GTR, Pagani Huara BC, and the rest of the gang trading paint and carbon fiber through Dunlop in a heinously expensive version of "Buy on Sunday, sell on Monday." The reality is that we don't have all the details yet on the set of regulations called "GTP," but the FIA wants race cars more closely tied to road cars, albeit with the performance level of today's LMP1 cars. Exterior design freedom would shelter internals designed to reduce costs, the FIA planning to mandate less complex hybrid systems and allow the purchase of spec systems. One of the FIA's primary goals is lowering LMP1 budgets to a quarter of their present levels. Audi and Porsche budgets exceeded $200 million, while Toyota - the only factory LMP1 entry this year and next - is assumed to have a budget hovering around $100 million. Reports indicated that Aston Martin, Ferrari, Ford, McLaren, and Toyota sat in on the development of the proposed class. If the FIA can get costs down to around $25 million, that would compare running a top IndyCar team and have to be hugely appealing to the assembled carmakers. The initiative represents another cycle of the roughly once-a-decade reboot of sports car racing to counter power or cost concerns. The FIA shut down Group 5 Special Production Sports Car class in 1982 to halt worrying power hikes, and introduced Group C. In 1993, Group C came to an ignoble end over costs; manufacturers were spending $15 million on a season, back when that was real money and not one-fifth of a Ferrari 250 GTO. Then came the BPR Global GT Series that morphed into the FIA GT Championship, which would see the last not-really-a-road car take overall Le Mans victory in 1998, the Porsche 911 GT1. That era would be most aligned with a future hypercar class.

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.
