On the heels of the hybrid Vespa prank comes news regarding a real “green” scooter: Bajaj Auto announced today plans are underway to bring a liquid-propane/compressed-natural-gas-powered scooter to the market next year. Bajaj rival Kinetic plans to release two electric scooter models in 2007 (presumably after they get those Dragster 180s on line). Bajaj might look for design inspiration from China’s Chongqing Union Auto Co., who are already selling Bajaj-branded CNG-powered three-wheelers, without permission. Bajaj has promised to challenge Gaongqing, but trademark infringement justice is hard to come by in China.
