According to the company’s news release, “Infiniti’s hybrid system, developed solely within Infiniti’s parent group, is a single electric motor/twin clutch arrangement.
The hybrid system will include a lithium-ion battery pack that is the same size as a conventional battery, but holds twice the power. The M hybrid will be able to run on battery power alone “in certain driving conditions.”
It will also provide a power boost when the car is under maximum acceleration and turn into a generator to supply electricity to the battery pack when the car is coasting or braking.
