Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.

Recharge Wrap-up: Mazda, Toyota earn environmental awards

Electric mobility nonprofit Drive Oregon has launched a campaign to invite the electric car industry to perform testing in the state. The campaign tells companies to, "Test Drive the Future in the Living Lab," citing Oregon's density of EV owners and charging infrastructure, varied terrain and climate, funding opportunities, and the state's technological reputation as the "Silicon Forest." Plus, as Drive Oregon Executive Director Jeff Allen, points out, "if you really screw things up here, it doesn't make as much noise as it would in California." Already, Jaguar Land Rover has announced plans for an Innovation Incubator in Oregon. Read more at Green Car Reports. Mazda's new paint system has won the Prime Minister's Award in the category of Manufacturing and Production Process at the 6th Monodzukuri Nippon Grand Award ceremony. Mazda's Aqua-tech paint system significantly reduces emissions of volatile organic compounds (VOCs) and CO2. The Aqua-tech system uses a water-based color basecoat and a urethane clear coat to reduce VOC emissions by 57 percent. It consolidates the painting process and reduces energy in paint-booth air-conditioning and flash-off processes to reduce energy consumption. It also allows Mazda to create such colors as Soul Red, which looks quite nice on the MX-5 Miata. Read more at Green Car Congress, and learn all about the Aqua-tech paint process from Mazda. The Toyota Mirai has received a 2015 Environmental Award from Austrian automobile club ARBO. The hydrogen fuel cell car took the prize in the category of Current Innovative Environmental Technologies. "At Toyota, we believe that various technologies will co-exist, ranging from EVs to hybrids to the most innovative of all, the fuel cell car," says Gerald Killmann, Vice President R&D of Toyota Motor Europe, in a comment thanking ARBO. "Mirai is a core component of Toyota's vision for a sustainable mobility society, one that allows us all to move freely in comfort and safety in an environmentally friendly, sustainable manner." Read more in the press release below. Vienna, Austria- November 5th - The Austrian automobile club ARBO* (Auto-Motor und Radfahrerverbund Osterreiche) has awarded the Toyota Mirai with the "2015 Environmental Award". This Award was received during a gala ceremony held yesterday in Vienna, where the Toyota Mirai was awarded in the category of "Current Innovative Environmental Technologies" . The jury consisted of ARBO automotive experts.

Next-gen Toyota Prius spied inside and out

Toyota has built itself into the industry's standard-bearer when it comes to hybrids, and it isn't going to let the poster child for gas-electric vehicles get stale on the market. These spy shots captured in California are our first good look at the next-generation Prius, which could come to market wearing a 2015 model year designation.
Even though it looks like Toyota may have blown its annual camouflage budget on this mule, we can clearly see that it will have the same iconic half-moon design that has been with the car since 2003. If so, this goes against reports from last year that suggested the car would be getting a different look inspired by the 2013 NS4 Concept. Although, this could also indicate that the Prius family will continue to grow - adding a new sedan - to the existing Prius C, Prius V and Prius Plug-In lineup.
These spy shots also give us an indication as to what the interior will look like, with a more stylish three-spoke steering wheel and an instrument panel design that sort of reminds us of a BMW. On the other hand, all the tape, cobbled together pieces and lack of space for a center stack display screen has us thinking this isn't what the final product will resemble.
