Existing off-road recreational vehicles like quads and side-by-sides have considerable environmental effects. Using fossil fuels and generating lots of noise to explore nature would be a paradoxical and ironic choice. ENVO wants to take the challenge and develop electric mobility solutions to explore nature with excellent efficiency on the road and off-road. Here are the main design requirements for submissions in this category: 

• Context of use: 
  • Recreational use, paved road, and off-road.
  • Horse ranches
  • Agricultural and farm work
  • Hunting
  • Security patrolling (e.g., festivals, large commercial buildings, etc.)
  • Search and Rescue

• Formfactor: 
  • Four wheels, stable design with a low center of gravity
  • Hub motors; either two or four-wheel drive.
  • Front and rear suspension. Travel to be determined by the designer.
  • Optional: Suspension could also be used as a steering input with a leaning mechanism,
  • The cockpit can be enclosed/weatherproof or open.
  • A modular platform is desirable, so variable options like seats and extendable cargo can be added or removed. 
  • Swappable and modular batteries to be used.

• Performance and constraints: 
  • Speed: 65 km/h
  • Motor power: Minimum of 3 kW. 
  • Range: Minimum 80km
  • Width: Maximum 110cm
  • Wheelbase: Maximum 200cm
  • Weight: Maximum 140kg (including batteries)
  • Power input: No constraints. Examples: Thumb throttle, foot pedal, etc.
  • Steering input: No constraints. Designer to consider power steering depending on the application. Examples: handlebar, leaning mechanism, etc.
  • Brakes: Hydraulic disc brakes. Regenerative braking is optional.
  • Wheel and Tire size: No constraint.
  • Lights: High power front lights + rear braking lights. Other lights are optional.
  • Turning Radius: 5m maximum
