This disclosure describes a stable, high-speed utility vehicle. In an implementation, an example utility vehicle provides stable, fast transport over snow and ice. A chassis places the center of gravity of the entire vehicle low for stability during quick turns at high speed. The hull of the vehicle can float over snow or loose debris. The hull includes angular side panels that grip and grab snow when the vehicle tilts substantially to one side. The sides constitute a rail or riding surface for the vehicle to support the vehicle during sideways traverse on a steep slope. Multiple simultaneous steering mechanisms enable the vehicle to turn stably, in a tight radius, even at relatively high speeds. In an implementation, the vehicle features a 200-500 HP engine with speeds of 60 mph to transport work crews to remote utility sites.
