Our hybrid technology transforms an original equipment manufacturers (OEM) vehicle into a hybrid vehicle by adding an electric motor, an advanced lithium-ion battery pack, and control software to the vehicle without making significant vehicle modifications or modifying the internal combustion engine or transmission.

The XL3 Hybrid Electric Drive System saves fuel through regenerative braking, a process by which the electric motor helps slow the vehicle during braking, to charge the hybrid battery. Then, when the driver accelerates, the hybrid battery releases the stored energy to the electric motor, helping to propel the vehicle. Our proprietary hybrid controls make the electric motor assist smooth and seamless to the driver and passengers.
