In the automotive world, aerodynamics is a necessity rather than a bonus. Low drag reduces wind resistance, improves efficiency, enhances EV range, boosts fuel economy, and stabilizes cars at high speeds. Some vehicles are designed with painstaking attention to airflow, producing record-breaking drag coefficients that make them nearly invisible to the wind. Let’s dive into the top 9 slippery low-drag cars that demonstrate the pinnacle of aerodynamic engineering, along with their model years and drag coefficients (Cd, which is a measure of how aerodynamically efficient a vehicle is).
Lucid Air (2022): 0.197 Cd
The Lucid Air is a luxury electric sedan with one of the lowest drag coefficients in production at 0.197.
