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 Hilux successor spotted

The midsize truck segment is suddenly seemingly exploding with new vehicles worldwide, even here in North America. Not only will the Chevrolet Colorado and GMC Canyon be available very soon, Toyota is already testing a replacement for its aging Tacoma and Honda has promised a Ridgeline replacement within the next 18 months. Also, the recently shown Nissan Navara is said to portend the future of our Frontier. Here's some more fresh evidence from Europe of this pickup boom with the next generation of its venerable Hilux in testing.
Thanks to Top Gear and sometimes the evening news, the Hilux has built a reputation of being able to go just about anywhere. According to out spy shooter, this particular pickup was spotted during hot weather testing in southern Europe. Interestingly, a Volkswagen Amarok was along for the ride as a benchmark. Because the VW tends to offer a bit more comfort than the generally utilitarian Hilux, this could indicate Toyota is considering taking the new truck in a slightly comfier, more refined direction.
Compared to the current model, this camouflaged tester sports a narrower front grille and headlights. The hood scoop is also absent here. The lower air dam also receives a more horizontal look, but the more vertical fog light housings provide some contrast. The crazy camouflage pattern makes things hard to discern at the rear, but the taillights appear to be more slender than they on the current model. Unfortunately, mechanical details about the new truck remain a mystery at the moment, but enjoy these spy shots as a preview of one more upcoming pickup.

Toyota and Mazda set to expand partnership

Toyota and Mazda are already teaming up for the Scion iA and Mazda2, but that partnership might just be the beginning. Reuters reports the two Japanese companies could expand their work together, with Toyota chipping in its experience with both fuel cells and plug-in-hybrid tech, and Mazda contributing its know-how in regards to its Skyactiv line of engines. The report cites a pair of unnamed sources that are "not authorized to discuss the matter publicly." The move, on the surface, is certainly appealing for both parties. Mazda has very little experience with hybrids (remember the Ford-rebadged Tribute Hybrid?), let alone something as advanced as a fuel-cell vehicle. Teaming with Toyota, arguably the world's greatest hybrid manufacturer, would give it a serious leg up. For the Japanese giant, meanwhile, a partnership with Mazda could expand the economy of scale for the Mirai FCV's tech, while Skyactiv engines would do well in replacing the base engines in cars like the Corolla, Camry, and RAV4.
