2014 Toyota Corolla and Tundra production underway

After months of leaked photos and speculative reports, Toyota finally unveiled its 2014 Corolla to the world in early July at a star-studded California party. The confetti has been swept up and the champagne flutes washed and stored, and now the real work can begin: production. Toyota has announced that its new C-segment player has begun rolling off the lines at its plants in Mississippi and Ontario, Canada this week ahead of the planned start of sales in September. What's more, the refreshed 2014 Tundra pickup has also segued into production in San Antonio, Texas.
Corolla production in Mississippi is still a relatively recent phenomenon, with the plant having begun assembly of the outgoing model in the fourth quarter of 2011, while Toyota's Cambridge, Ontario plant has been churning out the compact volume king since 1988. Conversely, the Tundra has been in production at the Texas facility since 2006, and Toyota projects that the plant will build its milestone one-millionth new vehicle in September, right around the time the reworked fullsize pickup goes on sale.

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 will steer clear of driverless cars

Toyota executives say the company's primary focus is on safety. At least for the time being, that means the company won't pursue development of a driverless car.
Speaking at the company's advanced safety seminar in Ypsilanti, MI, Thursday morning, Seigo Kuzumaki, Toyota's deputy chief safety technology officer, said that Toyota envisions a future driving environment that optimizes the best of both humans and computers, not choosing one over the other.
"Toyota's main objective is safety, so it will not be developing a driverless car." - Seigo Kuzumaki
