 The Aptera's 100 Wh/mile target translates to approximately 10 miles per kWh, significantly more efficient than some common electric vehicles like the Tesla Model 3 (around 239 Wh/mile). 

Why the high efficiency?
  • Aerodynamic design: The three-wheel design and sleek shape are highly aerodynamic, minimizing air resistance.
  • Lightweight materials: The use of a lightweight composite body contributes to the vehicle's low weight, reducing energy consumption.
  • Efficient powertrain: The vehicle utilizes efficient in-wheel electric motors.
  • Solar panels: The integrated solar panels contribute to the overall energy balance, potentially providing a significant portion of daily driving range. 
Factors that can affect efficiency:
  • Driving speed: Higher speeds increase aerodynamic drag and reduce efficiency.
  • Road conditions and terrain: Factors like uphill driving can increase energy consumption.
  • Driving style: Aggressive driving with frequent acceleration and braking can decrease efficiency.
  • Use of auxiliary equipment: Heating, air conditioning, and other electrical accessories can consume energy. 
In summary, the Aptera demonstrates remarkable energy efficiency, achieving levels around 122 Wh/mile in real-world testing with a target of 100 Wh/mile in the final production version. This exceptional efficiency is a key feature of the vehicle, contributing to its long range and potential for solar-powered driving
