What is a Hybrid? 8 -Increased Efficiency -Lower Emissions
-Limited Range -Long Range -Lower Efficiency -Higher Emissions
Slide 9
Types of Hybrid 9 Parallel: Higher power, but less efficient
Series: Better efficiency, but less power
Slide 10
The Design 10 Main Systems -Frame -Electric Traction -Internal
Combustion Traction -Drivetrain -Control
Slide 11
The Mixed Hybrid 11 The Red Devils will implement a mixed
hybrid design that combines the power of a parallel hybrid with the
efficiency of a series hybrid
