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.

Everything new at the 2019 New York International Auto Show

Transcript: Welcome to the 2019 New York Auto Show. It's the last auto show, and so far it's my favorite of the year. We have a new buggy, compact pickup and trail ready SUV from Volkswagen. Ford brought the new Escape and a new Mustang performance variant, and we have a brand new Toyota Highlander and Subaru Outback. Let's go take a look around. We're here at the New York Auto Show with the Subaru stand. Normally the Subaru stand is just some white carpet and some show lighting. This year it's like we're in a national park. It's ... Frankly, I'm from Oregon. You're from Colorado. Yeah. It's making us feel at home. And in that way what better place and what better people to introduce this Subaru Outback which is pretty much the official car of Colorado and Oregon. Yeah. You actually have to buy a Subaru before they let you move to Colorado. Now instead of climbing up there and taking a look because we've been told we can't do that we're gonna go over there and check out another one. So the exterior, not that different. No. Looks exactly like an Outback. There's actually oddly a little more black plastic trim on the outside. A little too much for me. Right. It's interesting because it kind of slowly went away from that from the beginning because in the beginning the black plastic trim kind of made it an Outback, and now they're kind of bringing it back. I guess they needed to make it more macho. Right. Right. Now we're inside. Inside it looks pretty different. Swank. It's kind of swank for an Outback which has been pretty plain. Now this is the newly available vertically gigantic touch screen here. 11.6 inches. That is massive. This is how big it is when it's turned on ... just for the viewers. Now this is the onyx trim. So with that you get the black mirrors, the black wheels. This upholstery is special to the onyx, so it's gray and black and you also have this green stitching. Yeah, I like this accent stitching. It's kind of neat. Oh there's also a little tray there. Well this is a deep bin here. You can probably fit a phone. There we go. Almost. Yeah there are two USB ports. There's an additional two in the backseat. So this thing here you pop in the cup holder and it gives you a little more space or less space. These are really big, so if you have one of those Nalgene bottles I'm guessing it's going to fit in there. One of my complaints about my Subaru that I own now which is a naturally aspirated Crosstrek is that up in the mountains. It's slow?

Couple survives 50-foot fall from overpass in Toyota

It doesn't matter the make or model - modern vehicles are technological miracles when it comes to occupant protection. Take this story out of New York City, which involved two people going for a very wild ride in a Toyota Matrix.
Carlos and Raquel Broadbelt were on the Cross Bronx Expressway overpass when they hit a patch of ice while dodging a pothole, sending them hurtling into a guardrail and over the side of the overpass. They fell 50 feet onto the road below. Despite the catastrophic accident - and the mangled Toyota - both driver and passenger walked away. The couple spent a night in the hospital just for observation.
The Broadbelts' miraculous survival has even surprised doctors, who told Dave Carlin from CBS New York they'd never seen an accident like it. Take a look below for the full news report from CBS New York.
