Overview

This research shows reduced fuel consumption in electric cars and vehicles through optimizing body shape, suggesting improved energy savings and lower greenhouse gas emissions.

Key Points

  • The study aims to explore aerodynamic drag reduction and improved cooling performance in vehicles.
  • Analysis of aerodynamic drag and thermal cooling of passenger cars and electric vehicles.
  • Evaluation of strategies for component design to optimize body shape and cooling systems.
  • Consideration of fuel consumption impacts under different driving conditions.
  • Achieved cooling drag reduction of around 7% without harming cooling performance.
  • Predicted fuel consumption reductions of approximately 2.9% for highway and 1.7% for city driving.
  • Electric cars have a battery-to-kerb weight ratio of about one-quarter of the kerb weight, affecting energy use.
