SPMM Plus is a vehicle Kinematics and Compliance (K&C) characteristic test system that acquires quasi-static suspension characteristics critical to vehicle ride and handling performance. This data can be used for benchmarking tests, prototype vehicle design, and as a basis for vehicle models widely used in simulation testing.

The SPMM adopts a fully electric body and fixed-ground design that faithfully simulates on-road vehicle behavior, with decades of application proving its efficiency, accuracy and reliability. The latest SPMM Plus is customized to meet the evolving needs of the automotive industry, featuring a larger motion range, advanced control system and the ability to accommodate larger vehicle sizes, with over 40 installation sites worldwide.
