A dynamometer system may comprise motorized rollers disposed on motorized rotational mounts such that the dynamometer may simulate lateral motion as well as longitudinal motion of a vehicle under test. A dynamometer system may comprise at least one roller for supporting a vehicle tire. The roller may be supported by a turn table. The roller and the turn table may be coupled to direct-drive rotational motors. The roller and the turn table may be configured to rotate about perpendicular axis. The dynamometer may be operated in a variety of modes which may allow for at least one of or combinations of evaluation of lateral dynamics, longitudinal dynamics, or vertical dynamics of a vehicle under test. In this manner, more realistic evaluation of vehicle performance can be obtained in a controlled environment.

Test rigs for dual-axle vehicle corner systems and methods of testing dual-axle vehicle corner systems are disclosed.
