+ ADVANTAGES

• No possibility of tire slip or tire pressure fluxuation
• Controlled loaded sweeps
• Natural Torque Distribution permits torque split for improved compatibility on most AWD vehicles
• Requires minimum floor space when not in use
• Fan speed proportional to speed
• Portable

– DISADVANTAGES

• Not a linked system which can be problematic for some AWD vehicles
• Longer setup time than roller dynos

The Rototest HUBDYNO® features a portable and relatively lightweight design. Rototest’s Perfect Dynamometer ConnectionTM (PDC) system is said to facilitate quick and precise connection of the drive hubs to the load cells. Each precision-machined load cell features a coil-over shock suspension system, and once mated to the drive wheels, permits suspension travel as the vehicle loads and unloads. This system also permits safe changes of steering angle while under load. Rototest states its low-inertia design reduces powertrain stress. To address the challenges of working with modern all- wheel drive vehicles that rely on sensitive mechanical and electronic center differentials for torque split, Rototest developed a technology called Natural Torque DistributionTM. This technology is said to permit safe and accurate measurement and control of modern AWD powertrains. The hydraulically driven fans connect to the load cells and convert the hydraulic pressure into road-simulated wind, up to 85 mph.
