SHERP of Kyiv has built amphibious all-terrain vehicles since 2015 that drive and float on enormous self-inflating tyres, inflated or deflated in under thirty seconds by exhaust gas. The 1,300 kg ATV carries a tonne behind a 44 hp Kubota turbodiesel; the Pro XT is the larger four-wheeler sold through ARGO of Canada; the N 1200 is insulated for the Arctic; and the ten-wheeled articulated Ark is 9.6 m long and carries 22 people or 7,500 lb.
The four-wheeled SHERPs: the 1,300 kg ATV on 63-inch self-inflating tyres with a 44 hp Kubota turbodiesel, 45 km/h on land and 6 km/h in the water; the larger Pro XT sold through ARGO with a Doosan D18 and seats for nine; and the insulated N 1200 for the Arctic.
Ten driven wheels on five axles, articulated in the middle: 9,632 mm long, 2,520 mm wide, 600 mm of clearance, a Doosan D24 of 320 N·m, and the same 63-inch ultra-low-pressure tyres as the ATV. The XTX carries 7,500 lb, the XTZ up to 22 people, and it swims at 6 km/h.
