What is the drag coefficient of an SUV?
The drag coefficient of an SUV (Sport Utility Vehicle) is a measure of the vehicle's aerodynamic efficiency. It is a dimensionless number that represents the ratio of the drag force acting on the vehicle to the dynamic pressure of the air flow. In simpler terms, the drag coefficient determines how much air resistance the SUV experiences as it moves through the air.
What is Drag Coefficient?
Drag coefficient, denoted as Cd, is a crucial factor in determining a vehicle's fuel efficiency and overall performance. It is a measure of how much the vehicle's shape and design contribute to the air resistance it experiences. A lower drag coefficient indicates better aerodynamics and less air resistance, which can lead to improved fuel economy and higher top speeds.
The drag coefficient of a vehicle is influenced by several factors, including the vehicle's shape, size, and surface texture. Streamlined, aerodynamic designs typically have lower drag coefficients, while boxy or angular shapes tend to have higher drag coefficients.
Drag Coefficient of SUVs
SUVs, by their nature, tend to have higher drag coefficients compared to more aerodynamic vehicle designs, such as sedans or hatchbacks. This is due to their larger size, taller profile, and often boxier shape. The average drag coefficient for an SUV is typically in the range of 0.35 to 0.45, though some more aerodynamic SUV models can have a drag coefficient as low as 0.30.
To put this into perspective, a typical sedan might have a drag coefficient around 0.25 to 0.30, while a sports car can have a drag coefficient as low as 0.22. The higher drag coefficient of SUVs contributes to their lower fuel efficiency compared to more streamlined vehicle designs.
Improving Drag Coefficient in SUVs
- Aerodynamic Design: Manufacturers are constantly working to improve the aerodynamics of SUVs through innovative design features, such as:
- Streamlined front and rear bumpers
- Smooth, sloping rooflines
- Underbody panels to reduce air turbulence
- Retractable side mirrors
- Active Aerodynamics: Some SUVs are equipped with active aerodynamic features, such as:
- Adjustable front grilles that can close at high speeds to improve airflow
- Deployable rear spoilers that enhance downforce and stability
- Lightweight Materials: Using lightweight materials, such as aluminum and carbon fiber, can also help reduce the overall weight of the vehicle, which can indirectly improve the drag coefficient.
By incorporating these design and engineering advancements, automakers are continuously working to lower the drag coefficient of SUVs, which can lead to improved fuel efficiency and better overall performance.
What SUV has the lowest drag coefficient?
2024 NIO EC7

What is the drag coefficient of a Toyota Highlander?
The streamlined look and high ground clearance help the airflow and give it a 0.34 drag coefficient.
What is the best drag coefficient car ever?
Lucid Air is the most aerodynamic production car, with a 0.197 coefficient of drag. Follow our quest to make Lucid Gravity the most aerodynamic, most sustainable and most advanced SUV ever.
What is the drag coefficient of a modern SUV?
Firstly, an SUV is large. Big 'boxy' objects tend to generate more drag. Historically, SUVs achieved drag coefficients of 0.35 to 0.45, but contemporary designs are now closer to 0.25 to 0.30. A similar trend can be said for small hatch back vehicles too.
What is the average drag coefficient of a SUV?
0.35–0.45
Sport utility vehicles (SUVs), with their typically boxy shapes, typically achieve a Cd=0.35–0.45. The drag coefficient of a vehicle is affected by the shape of body of the vehicle. Various other characteristics affect the coefficient of drag as well, and are taken into account in these examples.
What is a normal drag coefficient for a car?
The average modern automobile achieves a drag coefficient of between 0.25 and 0.3. Sport utility vehicles (SUVs), with their typically boxy shapes, typically achieve a Cd=0.35–0.45.
Is the .28 drag coefficient good?
Usually if a carmaker is bragging about it, it's in the low region, somewhere between 0.26 and 0.22 – and the lower the number, the better. For reference, an aerodynamically-ideal teardrop shape has a coefficient of drag of around 0.04.
What is the drag coefficient of a Rolls-Royce?
0.25
The all-new Spectre will also boast the lowest drag coefficient ever seen, at 0.25, making it the most aerodynamic Rolls-Royce ever.
What is the drag coefficient of the Honda CRV?
Why Honda CR-V SUV has better aerodynamics than Lamborghini Aventador….? Just realized that Honda CR-V SUV has a drag coefficient of 0.33 while Lamborghini Aventador has it around 0.38…
Is 0.35 drag coefficient good?
Pickups have both a larger frontal area and a poorer drag coefficient in the range of Cd 0.4-0.45. SUVs are better, but still typically manage only Cd 0.35-0.4. Regular cars are the most efficient, generally in the range Cd 0.3-0.35, though an increasing number, mostly in the prestige sector, get well below Cd 0.3.
