Some performance parameters of automobiles are: Acceleration: An important performance parameter in most types of vehicles. For example, the Society of Automotive Engineers (SAE) Baja competition scores a car based on the time it takes to go 150 ft from a resting start. Braking: A main performance parameter of automobiles that affects traffic safety. Brake power is the power obtained at the crankshaft, which drives the wheels. Aerodynamics: An essential part of a vehicle's performance and efficiency. Aerodynamics helps reduce air friction, also known as wind drag, on a vehicle's... Show more

Some performance parameters of automobiles are:

Acceleration: An important performance parameter in most types of vehicles. For example, the Society of Automotive Engineers (SAE) Baja competition scores a car based on the time it takes to go 150 ft from a resting start.
Braking: A main performance parameter of automobiles that affects traffic safety. Brake power is the power obtained at the crankshaft, which drives the wheels.
Aerodynamics: An essential part of a vehicle's performance and efficiency. Aerodynamics helps reduce air friction, also known as wind drag, on a vehicle's body.
Fuel power: Vehicle specifications include fuel capacity, power, torque, and displacement.
Combustion mass balance: The combustion process can be modeled by applying laws of mass and energy conservation to the processes in the engine cylinder. Basic design and performance parameters include compression ratio, swept volume, clearance volume, power output, and indicated power.
Battery technology: An automotive lithium-ion battery pack is a device that provides energy to the electric vehicle. 

Other performance parameters of automobiles include:
Maximal speed
Maximal climbing angle
Mileage in a certain condition
Hydrogen consumption in a specific cycle
