Torque tube

Employing a torque tube to unite the front-mounted engine with the rear-mounted

transaxle creates an outstanding level of powertrain rigidity.

This aspect is essential in order to extract the most performance out of a vehicle. A

rigid powertrain reduces parasitic losses that occur from unwanted engine movement

and input from the wheels, allowing a greater amount of power to be sent to the road

and a more direct response.

Torque is transferred by means of an input shaft housed within the torque tube. This

fast-spinning shaft is mounted using rubber insulators with integrated bearings to

ensure quietness.

A front counter gear is employed,

allowing the engine to be placed

closer to the ground. The engine

crankshaft axis is lower to the

ground than the input shaft axis.
