To organize all thoughts in selecting 3- or 4-wheel, I will make a decision matrix and select all criteria that must be considered.
When discussing a 3-wheel design we will be considering both a tadpole/teardrop shape and a delta shape as shown below.
Criteria | Weighting | 4-Wheel | Delta | Tadpole | Notes |
|---|---|---|---|---|---|
Suspension | 0 | This criteria is broken up into the design, manufacturability, and assembly of the front and rear suspension. Both will be factored into the final decision. | |||
