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 Prius sales could come up short in 2013

A Toyota executive has said that the automaker's hybrid Prius model may not reach its 2013 goal of selling 250,000 units in the US marketplace. Bill Fay, group vice president for Toyota's US sales, told Reuters, "The 240,000 to 250,000 range is kind of where we're settling our sights for the Prius family."
The first-generation Prius, a five-passenger model, was introduced to the States in 2001 (its arrival made it the second mass-produced hybrid, after the two-seat Honda Insight). The second-generation model arrived in 2004, followed by the current third-generation design that arrived for the 2010 model year. The automaker has subsequently added the Prius V, a hatchback wagon (shown above) and the Prius C, a subcompact hatchback. As of March, 2013, cumulative worldwide sales of the Prius had reached 3.67 million units.
Last year, Toyota sold 236,659 Prius models in the US. However, sales of the model have fallen 5.1 percent in the first six months of 2013. In response, the automaker has boosted its marketing for the model, and the promotions are expected to continue through at least July.
