Moreover, unlike propulsion on a roller ergometer or a dynamometer, MWC propulsion on a motorized treadmill allows for greater freedom of MWC movements and some inertial effect exposure linked to the acceleration/deceleration of the wheelchair and head-trunk-upper limb segments.
The controlled system disturbance rejection is tested by applying a step torque to the chassis dynamometer rollers against the wheel rotation direction.
Motor Trend magazine put an S8 on a chassis dynamometer — a set of weighted rollers used to measure power output at the tires — and found it making 479 horsepower at just over 6,300 rpm.
For those of you who don't know what a dynamometer is, it's basically 2 very big rollers in the ground that will allow the drive wheels of the vehicle to turn without the car actually going anywhere, as seen in the picture above.
A force measurement system, referred to as "dynamometer", for accurately acquiring the contact forces and moment in a single-wheel roller rig using piezo-electric load cells is designed and developed.

Definitely a roller coaster.
