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 will steer clear of driverless cars

Toyota executives say the company's primary focus is on safety. At least for the time being, that means the company won't pursue development of a driverless car.
Speaking at the company's advanced safety seminar in Ypsilanti, MI, Thursday morning, Seigo Kuzumaki, Toyota's deputy chief safety technology officer, said that Toyota envisions a future driving environment that optimizes the best of both humans and computers, not choosing one over the other.
"Toyota's main objective is safety, so it will not be developing a driverless car." - Seigo Kuzumaki

Report: Daihatsu leaving European market

More than any other, two carmaking giants sit at the top of the industry: Toyota and General Motors. But while GM sells under a (shrinking but still) expansive range of brands, the Toyota Motor Corporation sells most of its vehicles under its own name. That doesn't mean that Toyota, however, doesn't have its own portfolio of subsidiaries. Here in the United States we have the youth-oriented Scion division, while Lexus handles its upscale offerings, and overseas there's Daihatsu.
The budget brand offers a range of small cars under its own name; most are hatchbacks, but there's also the Copen roadster and even a rebadged Camry called the Altis. You may have come across some of their offerings while traveling overseas, particularly in Europe, but that last part is about to come to an end, according to reports.
Word from across the pond is that Toyota plans to withdraw Daihatsu from the European market altogether. The move would reportedly take effect in 2013, and if it comes to pass, would follow similar withdrawals from the North American (1992) and Australian (2006) markets. Thanks for the tip, William!
