Introducing The Alternative Hybrid Vehicle Propulsion System       

Hydraulic hybrid systems use pressurized fluid, instead of electric power as an additional or alternative power source. Hydraulic systems are significantly more efficiently than electric systems recovering up to 75% of the vehicle's kinetic energy compared to 25% for electric.

The hybrid vehicles primary goal, is to reduce fuel consumption 

The Product

Using proven hydraulic hybrid technologies, we have produced a universal fit hydraulic hybrid conversion kit. "ITS" aftermarket hybrid conversion kit will significantly reduce the exhaust emissions produced by motor vehicles. The hybrid drive is suitable for all  medium to large truck and bus chassis units.

The outcome from installing the "hydraulic Drive Assist" hybrid system is a significant reduction in annual fuel costs, which in turn also reduces emissions. Maintenance costs and break repairs are also reduced as well as extending the vehicles usable life. 

Hydraulic Hybrid Features & Goals


Sold as a self installation aftermarket product
Up to a 30% reduction in fuel consumption and exhaust emissions
2 to 3 years payback or return on investment
A 50% reduction in maintenance costs
Single day installation of the hydraulic hybrid conversion kit
Designed for the life of the vehicle
Components are 100% recyclable , at end of vehicles life


Hydraulic Drive Assist is suitable for all types of buses



See the side profile image below of the Hydraulic Hybrid Drive Unit 2. 

To accommodate the close-coupled hydraulic motor (green object) the vehicles drive axle is replaced with a modified unit  

This configuration produces a very compact and robust hybrid drive unit. The advantage of this unit over our other designs, is it reduces component count for the system, and therefore increases reliability. This hybrid system is designed for the life of the vehicle, there are no expensive batteries to replace periodically as in the case in the electric hybrid buses.


The images above are of our suggested layouts for distributing the hydraulic accumulators and other hybrid components around the chassis. 

The accumulator bottles can also be mounted vertically against the back wall of the bus if space is available. 



Expressions of interest are sought from companies wanting to be an early adoptee of this emerging technology
