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.

Latest Forza Motorsport 5 car pack leaves us scratching our head (in a good way) [w/video]

As we scrolled down the roster of the latest car pack for Forza Motorsport 5, the Hot Wheels Car Pack, our expression became bemused over the strange mix of vehicles that we now have at our disposal. This is quite unlike any of the other sets of DLC Turn 10 Studios has offered. Sure, there are the typical headliner cars – the Lamborghini Veneno and 2015 Audi S3 – that will appeal to the mainstream racing fan or auto enthusiast. But this latest car pack is so jammed full of nuggets of automotive weirdness that it's hard not to get excited. The Hot Wheels pack has no shortage of racers, with a particular focus on historical offerings. A 1939 Auto Union Type D covers the pre-war era of Formula One, while a 1967 Lotus 49 and a 1952 Ferrari 375 represent post-war racing. For a modern twist, a Mazda USF2000 car slots in below the Indy Lights car from the Nurburgring booster pack. From here, things get vintage and weird. There are a pair of delightfully offbeat coupes, in the form of a 1974 Toyota Celica GT and a 1973 Ford XB Falcon GT (here's hoping we get a vintage Holden Monaro in the future). Those two are joined by a 1956 Ford F-100, which your author already plans on converting into a dragster with vinyl flames down the side (because that's what all vintage pickups should be). The new ride we're most excited about, though, is the 1983 GMC Vandura G-1500. Yes, that's the van from The A-Team, and we're sure it will prove to be an excellent canvas for the artists of FM5 to cover with airbrushed, fire-breathing unicorns and mystical, gray-haired wizards (or just poorly painted letters that read "Free Candy"). This latest car pack is the final monthly car pack for FM5, although Turn 10 is quick to point out that while the monthly updates are over, there will still be new batches of cars made available to gamers. As for the Hot Wheels pack, it's available now on Xbox Live for $9.99. Scroll down for the press release from Turn 10 Studios, as well as a video of the newest additions to Forza Motorsport 5's vehicle roster. Forza Motorsport 5 Hot Wheels Car Pack Now Available Turn 10 Studios is bringing the Hot Wheels® Car Pack to "Forza Motorsport 5," available for download today. The pack features a collection of vehicles built from the ground up for the new generation that car fans can collect and customize while putting their virtual driving skills to the test.

How Toyota's neighbor delayed 23,000 of its deliveries

Don't you just hate when your neighbors' mess becomes your problem? Toyota certainly has good reason to be upset, after an dirty mishap at a steel mill delayed thousands of vehicle exports from its nearby port in Nagoya, Japan, (pictured above) by as much as a month.
The messy situation occurred on June 22 when the mill near the port lost power and had to burn off an excess buildup of coke oven gas - which isn't exactly a situation friendly to living beings or the environment. According to Automotive News, it caused a massive amount of smoke to emit from the plant that fell as soot and tar on about 23,000 vehicles that were waiting to be shipped out. Getting the models properly cleaned off has been quite a task. A team of 5,000 workers were at the port until this week getting them gleaming again.
Potential Toyota buyers in North America have no need to fret about getting a sullied car, though. A Toyota spokesperson told Automotive News that none of the vehicles were bound for this continent. The automaker is reportedly considering asking the mill's owners for reimbursement for the cost of the weeks of cleanup. Paying for the mistake is, after all, the neighborly thing to do.
