[1] Mechanical connection between front and rear axles (synchronization) gives you an opportunity to measure modern AWD cars equipped with high tech systems controlling torque distribution between front and rear wheels, also 2WD cars equipped with advanced traction control system in which all the wheels must rotate in equal speed (otherwise car ECU will not allow to measure the car).

[2] 4600x3800 in surface-mounted version.

[3] Maximum power depends on engine torque characteristic and engine rotations. Cars with higher engine power can be measured with lower accuracy.

[4] Maximum power depends on eddy current brake rotations.
