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.

2020 Kia Soul vs. subcompact crossovers: How they compare on paper

At 10 years old, the 2020 Kia Soul has entered its third, and potentially best, generation yet. To get here, it fought off other boxy hatchbacks such as the Scion xB and Nissan Cube. But now it faces all new competition: subcompact crossovers. They offer similar sizes, prices and flexibility as the Soul, but with a veneer of ruggedness. But the Soul is ready with its own rugged trim, the X-Line, plus the return of its powerful turbocharged variant. To see how the Soul stacks up to the fresh competition, we've compiled vital stats on all the tall hatches. Considering the prodigious size of the subcompact crossover segment, we've limited our selection to a few options that are similarly priced and sized to the Soul, and that offer a bit of funky styling. They include the Toyota C-HR, Nissan Kicks, Hyundai Kona and Honda HR-V. There are of course many more options, and you can create your own comparisons using our Compare Cars feature. (You can also check out our Mitsubishi Eclipse Cross comparison that includes a few larger choices). In the meantime, though, check out all the numbers on our selected vehicles in the chart below, followed by analysis after. Performance, fuel economy and drivetrains The crossover segment is diverse when it comes to powertrains, with all different displacements, induction systems and drive wheels. A surprising number of these supposedly rugged and off-road-oriented vehicles (at least more than normal cars) are front-drive only. These include the Nissan Kicks, Toyota C-HR and Kia Soul. But the Kona and HR-V offer all-wheel drive, with the Hyundai offering it on both engine options. Speaking of engine options, only the Kia and Hyundai have two possibilities, either a base 2.0-liter naturally aspirated engine, or a turbocharged 1.6-liter engine. The base engines have identical outputs of 147 horsepower and 132 pound-feet of torque, but the turbo engines differ. The Soul has 201 horsepower to the Hyundai's 175, but both make the same 195 pound-feet of torque. The Kicks, C-HR and HR-V all offer just one engine option, and they're all naturally aspirated. The Nissan's engine is the smallest and least powerful: a 1.6-liter engine making 125 horsepower and 115 pound-feet of torque. The HR-V is next with a 1.8-liter engine making 141 horsepower and 127 pound-feet of torque. The C-HR rounds out the trio at 144 horsepower and 139 pound-feet of torque from a 2.0-liter engine.

Foreign automakers pay from $38 to $65 per hour to non-union workers

As leaders for the United Auto Workers gather in Detroit for their Special Convention on Collective Bargaining to work out the negotiating stance for this year's new labor agreements with the Detroit 3 automakers, what they most want to do is figure out how to eliminate the two-tier wage scale. However, the lower Tier 2 wage has allowed the domestic automakers to reduce their labor costs, hire more workers, and compete better with their import competition. As it stands, per-hour labor rates including benefits are $58 at General Motors, $57 at Ford, and $48 at Fiat-Chrysler – a reflection of FCA's much greater number of Tier 2 workers. The Center for Automotive Research released a study of labor rates (including benefits) that put numbers to what the imports pay: Mercedes-Benz pays the most, at an average of $65 per hour, Volkswagen pays the least, at $38 per hour, and BMW is just a hair above that at $39 per hour. Among the Detroit competitors, Honda workers earn an average of $49 per hour, at Toyota it's $48 per hour, Nissan is $42 per hour, and Hyundai-Kia pays $41 per hour. The lower import wages are aided by their greater use of temporary workers compared to the domestics. Automotive News says the ten-dollar gap between those foreign camakers and the domestics turns out to about an extra $250 per car in labor, which adds up quickly when you're pumping out many millions of cars. That $250-per-car number is one that, come negotiating time, the Detroit 3 will want to reduce, as the UAW is trying to raise both Tier 1 and Tier 2 wages. Another wrinkle is that the domestic carmakers are considering the wide adoption of a third wage level lower than Tier 2. Some workers who do minor tasks like assembling parts trays kits and battery packs already make less than Tier 2, but the UAW will be quite wary about cementing yet another wage scale at the bottom of the system while it's trying to fight a bigger battle at the top.
