Hummer UK have converted this H3 to remote control. Intended for off road use only, it can traverse 16-inch vertical walls, 40% side slopes and two feet of water, all while you stay level and dry, presumably from the comfort of a lawn chair.
The lads and ladettes over at Hummer UK are all about the crazy marketing stunts, having put the first H3 imported into the tiny island nation into a gigantic toy box. This R/C conversion was carried about by Cranfield Universty and continues the Big Boy's Toy marketing theme. It's interesting to see the vehicle being marketing solely on its recreational image, but the company does note that a diesel H3 will be available "within three years."
