Toyota mini doc chronicles Tundra towing Space Shuttle Endeavor

Toyota has worked up a quick video detailing the brand's involvement in the transportation of the Space Shuttle Endeavour last year. As you may recollect, the California Science Center ran into a hitch when it came to moving Endeavour from LAX to its new home. While most of the route would be covered by a robotically controlled transporter, one portion of the route directed the shuttle over an interstate. Unfortunately, the bridge across wasn't designed to stand up to the weight of the shuttle and its motorized sled.
The Science Center would have to remove Endeavour from its transporter and place it on a lighter, non-motorized sled. That's where longtime Science Center sponsor Toyota came in. As it turns out, the automaker had to prove to the California Science Center that a Tundra could actually tow the massive shuttle, so engineers put on a little demonstration with a stock truck pulling the equivalent weight over flat ground for the same distance. Once the Science Center was satisfied that the Tundra could pull it off, the move was green lit and the rest is history. Check out the short documentary below for yourself.

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.

Total auto recalls already on record pace in 2014

If you've noticed that there have been more recalls than usual this year, you may be on to something. According to a report from the National Highway Traffic Safety Administration, the US market is on pace to break a record for recalls. In 2013, 22 million cars were recalled. We're only a third of the way through 2014, though, and we've already halved that figure, with 11 million units recalled. That's wild.
Considering the past few months, it shouldn't be a surprise that General Motors is leading the charge, with six million of the 11 million units recalled coming from one of the General's four brands. Between truck recalls, CUV recalls and the ignition switch recall, 2014 hasn't been a great year for GM.
Other recall leaders include Nissan (one million Sentra and Altima sedans), Honda (900,000 Odyssey minivans), Toyota (over one million units in a few recalls), Volkswagen (150,000 Passat sedans), Chrysler (644,000 Dodge Durango and Jeep Grand Cherokee SUVs) and most recently, Ford (434,000 units, the bulk of which were early Ford Escape CUVs). So while it's been a bad year for GM so far, its competitors aren't doing too well, either.
