The coefficient of drag of the 2023 Hyundai Sonata Hybrid is 0.24.
A drag coefficient, or Cd, measures how much aerodynamic resistance a vehicle creates relative to its frontal area. Lower values generally mean air can flow around the car more efficiently, reducing the energy needed to maintain speed. The regular 2023 Sonata is commonly listed at 0.27, while the Hybrid’s aerodynamic body achieves the lower 0.24 figure.
Hyundai’s design uses details such as active grille shutters, a shaped rear spoiler, underbody airflow management and aerodynamic wheels. These features help reduce turbulence and keep air attached to the body as it moves down the road. The hybrid’s streamlined shape complements its gasoline-electric powertrain, especially during steady highway driving.
A common mix-up is confusing Cd with fuel economy. A 0.24 coefficient does not mean the car automatically achieves 24 mpg or 24 percent savings; it is only one factor among weight, tires, gearing, engine efficiency and driving conditions.
