Technicalities of Hybrid Cars

Different Types of Hybrids 1) Mild Hybrid Cars 2) Full Hybrid Cars 3) Plug-in Hybrid Cars 4) Muscle Hybrid Cars

Different Types of Hybrids 1) Mild Hybrid Cars A) Engine shuts off while coasting and stopped. B) Some use regenerative braking. C) Use the electric motor to assist the gas motor when needed. D) Doesn’t get the same fuel economy improvements as full hybrids (usually around 10%).

Different Types of Hybrids 2) Full Hybrid Cars A) Engine shuts off while coasting, stopped, and in reverse. B) Use of regenerative braking. C) Can propel vehicle on electric motor alone (up to 15mph). D) Achieves much greater fuel efficiency (up to 70% in the city). E) Uses a NiMH battery.

Different Types of Hybrids 3) Plug-in Hybrid Cars A) Engine shuts off while coasting and stopped. B) Use of regenerative braking. C) Can propel vehicle on electric motor alone for up to 50 miles. D) Achieves much greater fuel efficiency (numbers vary from over 100mpg to 50mpg and depends on it’s all electric range). E) Uses multiple battery types but most use Lithium-ion. F) Still many issues to work out (Battery, charging, cost).

Different Types of Hybrids 4) Muscle Hybrid Cars A) Uses hybrid technology to increase speed and performance as it’s main goal. B) Little to no increase in fuel economy.

How Hybrids Improve Fuel Economy 1) Turn Kinetic Energy into electrical energy through regenerative braking. 2) Sometimes shut of the engine. For instance at stop lights during initial acceleration and low speeds. 3) Use improved aerodynamics to reduce drag. 4) Use low resistance tires to reduce rolling resistance. 5) Use lightweight materials.
