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.

Kia EV9 wins 2024 World Car of the Year and World Electric Car at New York Auto Show

The Hyundai Group refuses to release its kung-fu grip on winning prestigious vehicle awards, especially those for electric vehicles. In 2020, Kia took the overall World Car of the Year (WCOTY) title with the Telluride, won World Performance Car with the EV6 GT, and won the World Urban Car category with the Kia Soul EV. In 2021, after the Hyundai Group walked away with nothing but a free lunch, the Hyundai Ioniq 5 won the 2022 World Car of the Year laurels, plus World Electric Vehicle and World Car Design of the Year, followed in 2023 by the Hyundai Ioniq 6 winning the same three awards. Kia returns to the top step today, the new EV9 announced at the New York Auto Show as the 2024 World Car of the Year and World Electric Vehicle. Because the South Koreans like to do this in threes, the Hyundai Ioniq 5 N won World Performance Car.  One hundred automotive scribes from 29 countries tested 38 vehicles for the main prize. The qualifications for entry are that a car must exceed 10,000 units in production annually, be on sale in at least two major global markets, and be priced below the luxury options in their respective regions. The EV9 beat the BYD Seal and the Volvo EX30 to the WCOTY title. Thirty-two cars vied for honors in the electric category, the EV9 outdoing the BMW i5 and the Volvo EX30. The German and the Swede aren't leaving New York with nothing, however, as the BMW 5 Series and i5 won the World Luxury Car title, and the EX30 won the World Urban Car trophy.  The Hyundai Ioniq 5 N outdid 16 other performance cars. We're sure there are engineers in Germany looking hard into their beer right now, the Ioniq 5 N pipping the M2 and XM to the victory circle.  The surprise of the bunch is the inclusion of the Toyota Prius, the global hybrid icon thrashing 70 other entries to win the 2024 World Car Design of the Year award. The other two finalists? The Ford Bronco and the Ferrari Purosangue. Ladies and gentlemen, give it up for the Prius.
