Criteria | Weighting | 4-Wheel | 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. | ||||

Steering | 0 | This criteria is broken up into the design, manufacturability and assembly of front, rear, or all-wheel steering. In this case, we will use the best scoring implementation of the three steering types. Consider this a child decision matrix. | ||||
Front | 1 | 0 | 0Delta wins due to the simplicity of only having 1 wheel in front, and tadpole and 4 wheel remain identical due to both having 2 wheels up front -Malcolm | |||
Design0 | 0Delta only has to connect to one wheel, while tadpole remains virtually the same due to also being connected to 2 wheels -Malcolm | |||||
Manufacturability0 | 0Delta has very few components just have to make sure it maintains positive caster, and again, tadpole is the same as 4 wheel -Malcolm | |||||
Assembly | 0 | 0 | Delta takes up very little space, and is not complex, so stuff could be built around it, although car shape might limit potential space -Malcolm | |||
Rear1 | 0 | |||||
Design | 0 | 1 | Tadpole now has the rear advantage, as it only has one wheel, and delta loses that advantage -Malcolm | |||
Manufacturability | 0 | 1 | Rear steering only would be difficult to design for in general, but again tadpole benefits here from only having 1 wheel, although being able to maintain a positive caster while also wrapping the steering all the way around the car could prove difficult -Malcolm | |||

Brakes | 0 | With the assumption that the implementation of brakes will be relatively equal between different wheel allocations (only front, only back, all wheels), we will only look at the over arching difficulty. Brake wheel allocations is being worked on by Ayush. | ||||

Motor Allocations | 0 | Typically, for tadpole design the vehicle is rear wheel drive - Evan Dodd Consider the number of motors and if a differential would be required https://www.youtube.com/watch?v=gIGvhvOhLHU&t=282s |
