Specific Purpose - To inform my audience about hybrid vehicles.
Central Idea - Hybrid car history and different platforms of hybrid vehicles.
Introduction

I. A hybrid car is a vehicle with more than one power source such as a small internal combustion engine and an electric motor.
II. Most hybrids only use gasoline when needed. The electric motor, powered by a stack of rechargeable batteries, is the primary workhorse for propulsion under low-speed driving.
III. When you think of a hybrid vehicle, you may find yourself thinking Toyota Prius.

A. Some mild hybrids will also be equipped with regenerative braking that will essentially charge the battery packs under braking.
B. Mild hybrids are not capable of exclusively operating on the Electric motor.

2. A Series hybrid platform, sometimes referred to as range-extending electric vehicles (REEV) incorporate a configuration by design to be operated mostly by the battery, but will have an ICE (Internal Combustion Engine) to recharge the battery when enduring a long drive.
B. Series hybrid’s only have electric motors to provide propulsion while maintaining an exceptionally high power to weight ratio providing enough torque over a broad range of speeds.
C. The gasoline engine drives an electric generator which charges the battery bank at which point the electric motor use the power from the battery bank to drive the vehicle.
Conclusion
