PROBLEM TO BE SOLVED: To improve fuel economy, and to enhance braking performance and turning performance. SOLUTION: This vehicle includes a body 11, front wheels and rear wheels rotatably disposed in relation to the body 11, and wheel driving parts 31 and 32 disposed between the rear wheels and the body 11 to impart a camber angle to the rear wheels. A friction coefficient between each tire of the rear wheels and a road surface is made smaller than that between each tire of the front wheels and the road surface. Since the friction coefficient between each tire of the rear wheels and the road surface is made smaller than that between each tire of the front wheels and the road surface, fuel consumption of the vehicle can be improved. Since the friction coefficient between each tire of the front wheels and the road surface is made larger, accelerating performance and braking performance can be sufficiently enhanced. The camper angle is imparted to the rear wheels, and thereby lateral force is generated, cornering force can be generated and turning performance can be enhanced. COPYRIGHT: (C)2010,JPO&INPIT |
