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.

Spongebob Squarepants Toyota Highlander gets Tanked in Vegas

In 2006, I bought a Scion xB (the super upright, first-generation one), and I always had this wild dream of turning the xBox into an aquarium after it had run its course in my personal test fleet. Long story short, that never happened. But apparently the folks at Toyota got wind of my idea - only, well, this isn't exactly what I had in mind.
Let's just start at the beginning here. This is a 2014 Toyota Highlander - you know, the redesigned one that bowed in New York earlier this year. I haven't driven it yet, but I'm sure it's plenty nice and will appeal to all sorts of families. Families with kids. Kids who like cartoons. Cartoons like Spongebob Squarepants.
Which brings me to our next talking point: the collaboration between Toyota and Nickelodeon for the Spongebob-themed wrap that covers every inch of this Highlander. This isn't the first time we've seen the yellow cartoon sponge on a Highlander - Toyota unveiled a differently wrapped version earlier this year - but this one features more of an aquatic, under-the-sea sort of theme. Perfect, considering the main point of this crossover's reason for being at SEMA.
