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.

Toyota, Ford decide to end hybrid collaboration before it starts

Not all so-called Memorandum of Understanding pacts end in actual collaborations. For instance, after a two-year "feasibility study," Toyota and Ford have just announced that they will not be developing hybrid systems for use in light trucks and SUVs as previously planned, and the two automakers will instead continue to develop their own hybrid technology independently.
The would-be collaboration was first announced in August of 2011, and would have seen a rear-wheel-drive hybrid platform that would "improve the efficiency of trucks and SUVs while still allowing them to be driven in the way customers expect," according to our initial post on the topic.
Keep in mind that this announcement isn't to say we shouldn't expect hybrid pickups and SUVs from the two automakers, but that they probably aren't coming very soon - Ford says it will have a system "before the end of this decade" and we haven't heard much from Toyota on the hybrid truck front since the 2008 A-BAT Concept (pictured above) - and that they will not share any components between them (and they never have, for what it's worth).

Santa swaps his sleigh for a Ferrari-powered Toyota

A Ferrari-powered Toyota 86 is sure to garner a bit of attention, as well it should. We've been paying attention throughout this build, so it should be no surprise then that Santa did as well. He's ditched his red sleigh for the Gumout GT4586 in this video. If you've been following along, you know that Ryan Tuerck and Gumout built this completely bonkers machine that's far more exciting than some previous Japanese/Italian mash-up automobiles. Donut Media has been doing their part to document and promote every stage of the process. This new video is filled with the gratuitous amounts of lights, noise, and tire smoke that Donut is known for. We don't know the conversion from horsepower to reindeerpower, but the GT4586 should provide plenty of oomph for Santa's Christmas trek.
