Toyota and Subaru file patents for performance FR-S and BRZ

People have longed for a more powerful version of the Subaru BRZ, Scion FR-S, and Toyota GT86 since the triplets arrived on the market. So far, neither partner in the deal has launched a model to fully satiate that hunger. However, the Japanese patent office recently approved documents from Toyota for the design of a vehicle that looks just like the Subaru STI Performance Concept (pictured above). According to AutoGuide, the filing also gives Fuji Heavy Industries credit for the design. The STI Performance Concept debuted at this year's New York Auto Show as an early step in STI's attempt to expand its reach here. The BRZ-derived coupe featured a body with a ground-scraping front bumper, tweaked headlights, wider fenders, a massive rear wing, and diffuser with a center-exit exhaust. All of these elements also show up on the patent renderings. The concept was just as exciting under the hood because STI installed a 2.0-liter, turbocharged boxer four-cylinder from its GT300 racer, and upgrades for the chassis, suspension, and brakes came from the Japanese market's BRZ tS. While the coupe made hearts race, the company was clear it didn't necessarily plan to build the model. Patent filings aren't a guarantee for production, and even if this one does arrive in showrooms, it might not come to the US. That's because Subaru and Toyota have a history of creating Japan-exclusive versions like the tS or Style Cb. That being said, spy shots have revealed a camouflaged GT86 testing in Europe, and rumors indicate more power from the engine. Subie's boss has even confirmed the existence of a partnership to create a next-gen model. 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.

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.

Toyota Recalling 516,000 Vehicles In Three Recalls

Toyota said Thursday it's recalling 516,000 vehicles worldwide - including 430,500 in the U.S. - for three separate safety problems, including brakes that can activate without warning. The company said it has no reports of accidents or injuries due to the defects. In all three cases, the company will alert owners and dealers will repair the issues for free. The largest recall, of 450,000 Sienna minivans from the 2004-2011 model years, targets vehicles sold in cold weather areas. Toyota said road salt can corrode the spare tire carrier under the vehicle and the tire can fall off. Siennas from the 2004-2010 model years were for the same issue in 2010, and a splash protector and anti-rust protection were applied. But the company says the splash protector can fall off and rust can still occur. The recall involves 370,000 minivans sold in the U.S., 80,000 in Canada and 400 in Europe. Also recalled Thursday were: - 16,000 Lexus GS 250 and 350 sedans from the 2013 model year because a manufacturing defect can cause the brakes to activate without warning, and without turning on the brake lights. Most of the vehicles - 10,500 - were sold in the U.S. Also included are left-hand-drive sedans sold in Canada, China and Europe. - 50,000 Highlander and Highlander hybrid SUVs from the 2014 model year. Toyota says a software glitch may prevent the vehicle from properly calculating the size of the front passenger when determining whether to fire the air bags. The affected vehicles assume the passenger is smaller, so the bags may not fire or they may fire at a lower speed than necessary for a larger passenger. Toyota says most of the affected vehicles - 45,287 - were sold in the U.S. Around 3,400 were sold in Canada and the rest were sold in Mexico and Europe.
