VT-4 Modular Dynamometer
Two axle modular dynamometer, designed for cars with one or two driven axles. It allows for the measurement of power and torque in the inertial mode.
Full synchronization (1:1), enabling the measurement of the most modern cars with an active central differential or advanced traction control. Fully upgradeable. Standalone or in-pit.

[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] 5750 x 3210 for in-pit (floor level) mounted version.
[3] Maximum power depends on engine torque characteristic and engine rotations. Cars with higher engine power can be measured with lower accuracy.
