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 increasing Yaris Hybrid production to 222,000 this year in France

More fuel economy means more factory workers and more production for Toyota's most popular model in Europe. That simple equation explains why the Japanese automaker is boosting annual production of its gas- and hybrid-powered Yaris compact vehicles at its French factory. The new number will be about 222,000, a 15 percent increase. To do that, Toyota will need to add about 500 workers to bring its total there to more than 4,000, UK's The Green Car Website says. Vive le Toyota! Toyota updated the European Yaris in the middle of 2011 and added a hybrid version later that year, the model has many fans across the pond. It helps that they hybrid is rated (using the friendlier European standards) at a whopping 81 miles per gallon, a tremendous number for a car that costs approximately $26,000. Toyota could soon have a bit more room in the small hybrid segment, since it was reported recently that Honda would discontinue European sales of its Insight and CR-Z hybrids soon. That decision was made easier because of increasing competition from Toyota, which boosted hybrid sales in Europe last year by 43 percent. In contrast, both the CR-Z and Insight experienced more than a 60-percent plunge in European sales in 2013.

Why Lexus shies away from plug-in hybrids

Lexus may have softened its stance a bit from the anti plug-in vehicle ads the Toyota luxury badge ran last year, but at least one executive from the company casts a pretty critical eye towards the concept as a way to cut both emissions and refueling costs. In fact, Lexus doesn't really buy the fact that buyers of plug-in hybrids are really looking to save both gas and the environment, Green Car Reports says, citing an interview at the recent New York Auto Show with Lexus executive Mark Templin. Templin also said hydrogen fuel-cell technology may be a better way to edge towards zero emissions. Templin decried plug-in hybrid technology because it adds weight to vehicles, which contributes to poor emissions figures in the process. He added that plug-in vehicle buyers are motivated more by potential tax credits and solo driving rights in high-occupancy vehicle (HOV) lanes than cutting back on fuel use. Last summer, Lexus ran an supposedly tongue-in-cheek print ad poking fun at how long it takes to charge a plug-in vehicle and how using air conditioning can shorten a car's charging range. Last spring, Lexus had to backpedal from an anti-electric ad it ran that had serious mistakes about hydrogen infrastructure. News Source: Green Car Reports Green Lexus Toyota Hybrid PHEV
