Hyundai Prius-fighting hybrid spied wearing new camo

Hyundai's engineers certainly don't want the public to see its upcoming dedicated hybrid model in several of these new spy shots, but the company can't deny that the machine is on the way. These test cars were first spotted last summer as Prius-like five-door hatchbacks. However in these photos and the second set, it would seem that the model has morphed into a more sedan-like shape similar to the Chevy Volt. Unlike the last time we saw this car during arctic testing, the vehicle no longer is covered in plastic concealment. That obfuscation has been replaced with a very effective camo pattern on everything but the roof, and in several photos, workers are actively standing in the way of the spy shooters' lenses. Beyond the whole model's general shape, there are a few details to pick out, though. You can easily spot the outline of the brand's hexagonal grille up front. There appears to be a rather complicated air dam design there, too. In profile, the shape of the rear hatch creates an integrated spoiler at the back. While the camouflage makes it very hard to tell, we don't see a plug-in port on this example. According to our spies, this test car was being driven with a slew of other electrified models, including a BMW i3, Nissan Leaf, Volkswagen e-Golf, and Kia Soul EV. Given that group, perhaps the engineers were specifically benchmarking the electric performance for this outing. Earlier reports suggest that Hyundai's latest hybrid could debut in the second half of 2016. Power reportedly comes from a 1.6-liter four-cylinder with hybrid assistance and a lithium-ion battery. Plug-in and five-door hatchback versions are also rumored.

New Toyota Supra may get a twin-turbo Lexus V6

We've heard endless rumors that a successor to the much loved and much missed Toyota Supra is in the works. Toyota hasn't done much to deny these conversations. On the contrary, the FT-1 concept from two years ago and the partnership with BMW have only fueled the fire. Now, talk of a new Lexus engine has led to speculation about the supposed Supra's powertrain. To be clear, this is mostly heresay. Few things have actually been confirmed, but based on what we know a few conclusions can be drawn. We know that BMW and Toyota are working on a joint product. We've seen mules testing out in the wild. In BMW guise, the possibly Austrian-built car will more than likely powered by turbocharged inline four and six-cylinder engines. Unless Toyota wants to use Bimmer power, they'll need to shoehorn one of their own under the hood. That leads us to this rumor of a twin-turbocharged V6 that will presumably power the new Lexus GS and LS. Japanese automotive publication Mag-X first reported on this engine. It was then picked up by YouWheel and Car Keys. Mag-X cites Toyota insiders and even gives an engine code, 943F. This engine allegedly will make more than 400 horsepower and more than 300 lb-ft of torque. While unconfirmed, this makes sense for Lexus. Nearly every luxury competitor has a six-cylinder engine with forced induction. While Toyota has previously had turbocharged inline-sixes, they've never produced a factory turbo V6. Every automaker is downsizing engines in an effort to meet fuel economy and emissions regulations. Toyota and Lexus will follow suit. Taking that V6 and tuning it for a performance application is a solid, if unverified, possibility. Related Video:

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.
