Translogic 164: Driving the fuel cell vehicles of the 2014 LA Auto Show

The LA Auto Show is known for its environmentally friendly vehicle debuts. At last year's show, hydrogen fuel cell concepts from Honda and Toyota joined a lease-ready Hyundai Tucson FCEV to cast a green hue over the convention center. This year, automakers took us a step closer to a fuel cell future by offering drives of their hydrogen-electric hybrids. Translogic host Jonathon Buckley takes a ride in the Toyota Mirai, which is headed for production in 2016. He follows that with a spin in the Volkswagen Passat HyMotion and the Audi A7 Sportback h-tron quattro concept. Which of these fuel cell vehicles holds the most promise? Tune in to find out.

2014 Toyota Corolla details leaked

Toyota will launch the 2014 Corolla later this year, and thanks to the ever-leaky internet, a couple of key details about the new sedan have been revealed. Car and Driver was able to uncover these bits of information thanks to someone at a Toyota dealer in Kansas who has seen the car, as well as its order guide, though the dealer's site has since removed its original posting.
We got our first glimpse at the next-generation Corolla's design at the 2013 Detroit Auto Show, where Toyota unveiled the Furia concept, pictured above. Yes, it looks all sporty and aggressive, but fear not, appliance shoppers, C/D says that the production car should have a couple of Furia bits mixed in with a huge helping of Camry-inspired styling.
The 2014 Corolla will reportedly continue to use a 1.8-liter four-cylinder engine, though the mill has been massaged a bit, adding Toyota's Valvematic continuously variable valve timing. A four-speed automatic (yep!) will be offered in the base model, though the manual transmission now has six gears, and higher trim levels can be had with a CVT. Both engine output and fuel economy numbers should improve slightly over the 2013 model. Currently, the Corolla produces 132 horsepower and 128 pound-feet of torque, and achieves 27/34 miles per gallon (city/highway) with the five-speed manual 'box.

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.
