Weekly Recap: Things you might not know about the 2015 Dodge Charger and Challenger Hellcats

If you're an enthusiast, and you don't know that Dodge spawned another Hellcat this week, you really must have been living in cave. The 2015 Dodge Charger SRT Hellcat is probably the biggest news for enthusiasts since the reveal of, well the 2015 Dodge Challenger SRT Hellcat.
But, there are some things you might not know or might have missed about the new Charger and Challenger Hellcats. For starters, reports that the Hellcat production would be limited to a low volume are not true.
"We have not capped the Hellcat on either the Challenger or the Charger," Dodge CEO Tim Kuniskis said.

BMW-Toyota joint sports car project is on like Donkey Kong

It's official - there will be a jointly developed sports car from BMW and Toyota. While the two auto giants signed a Memorandum of Understanding that pledged to pursue "joint development of architecture and components for a future sports vehicle" back in June of 2012, in the interim, it has remained unclear how those plans had been progressing. BMW has finally officially confirmed that the German and Japanese manufacturers will be codeveloping a pair of sports cars in addition to pursuing other disciplines including fuel cell systems and lightweight technologies.
"We have agreed on a joint architecture for a sports car. What is important is that there will be two different vehicles that are authentic to the two brands," BMW Development Chief Herbert Diess told Germany's Frankfurter Allgemeine Zeitung, Reuters is reporting. This is a very, very big step for both brands, but now the speculation can officially begin as to what the products of this agreement will look like.
There's ample reason to believe that the BMW-Toyota tie up will result in a Supra successor based on comments made by the chief engineer of the GT86/FR-S program, Tatsuya Tada, back in August. Follow that with a rumor from earlier this month that Toyota could debut a Supra concept car at the upcoming Detroit Auto Show later this month, and we could be seeing the fruits of this partnership sooner rather than later.

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.
