During operation, air resistance and road friction limit the speed of Oil Electric Hybrid Sedan, necessitating optimized aerodynamic design.

Improving the shape and propulsion fluid flow increases airflow to the Electric Car, reducing air resistance and thus improving acceleration performance.
Simultaneously, optimizing tire characteristics enhances rubber grip, reducing friction and increasing traction, further improving acceleration.
The acceleration performance of Oil Electric Hybrid Sedan is also limited by battery capacity, i.e., the current the battery can provide.
Therefore, increasing battery capacity and improving battery performance can enhance acceleration.
This requires timely battery replacement and updates to the electronic control system to improve battery utilization efficiency and reduce energy loss, thereby increasing the power and speed of the Electric Car.
