SUMMARY

The discussion centers on the feasibility of using a fiberglass monocoque structure for a 50-MPH electric three-wheeler. Key components identified include the WarP motor and Zilla controller, which operate on a 72-volt system. The design must accommodate two passengers and cargo while ensuring robust suspension mounting through molded-in metal hard points. The conversation highlights the critical balance between cost, battery weight, and range for effective electric vehicle performance.

PREREQUISITES
  • Understanding of fiberglass monocoque construction techniques
  • Familiarity with electric vehicle components, specifically WarP motors and Zilla controllers
  • Knowledge of electric vehicle range and performance metrics
  • Basic principles of vehicle design and aerodynamics
NEXT STEPS
  • Research the specifications and performance of the WarP motor
  • Investigate the capabilities and features of the Zilla controller
  • Explore fiberglass monocoque construction methods for automotive applications
  • Study electric vehicle battery technologies and their impact on weight and range
USEFUL FOR

Electric vehicle enthusiasts, automotive engineers, DIY project builders, and anyone interested in designing lightweight electric vehicles with efficient performance.

Electric car, it has to have a 50 mile range before recharge, carry two people with room for cargo (shopping), be a home garage project, i have been looking round and think the WarP motor and Zilla controller are a good drive system run on 72 volts.
Would a fiber glass monocoque with molded in metal (hard points) for suspension mounting
be robust enough, the top speed needs to be about 50 mph, acceleration needs fit with modern traffic.

The 3 main design considerations that will be powerful drivers in the cost of an electric car are the batteries (in both weight and cost), the motor (based on how heavy the car is, see batteries), and range/cruising speed.

In my opinion, "cheap" and medium to long-range EV's don't mix very well...
