Could be just the ticket for a compact PHEV range extender. Then again, it could be just another 1-day clickbait news story.The original engine on the kart weighed 40 pounds, producing up to 6.5 HP. The new X-Mini engine (core) weighs 4 pounds, and currently produces 3 hp at 10,000 RPM, and is expected to produce up to 5 hp at up to 15,000 RPM when development is completed. The X-mini engine can be configured to be used in drones, generators, mopeds/bikes/small vehicles, chainsaws, etc. The technology is inherently scalable, and can operate on a variety of fuels including kerosene / JP-8.
