What is the drag coefficient of a Ram truck?

Published in Automotive Aerodynamics 3 mins read

The 2024 Ram 1500 achieves a drag coefficient of .357, a notable figure for a full-size pickup truck. This impressive aerodynamic performance is a result of optimized aerodynamics combined with advanced active aerodynamic features designed to reduce air resistance.

Understanding Drag Coefficient

The drag coefficient (Cd) is a dimensionless quantity that quantifies the resistance or drag of an object in a fluid environment, such as air. A lower drag coefficient indicates less air resistance, meaning the vehicle can move through the air more efficiently. For automobiles, particularly large vehicles like pickup trucks, reducing drag is crucial for improving fuel efficiency, enhancing stability, and minimizing wind noise.

Ram 1500's Aerodynamic Performance

The .357 drag coefficient of the 2024 Ram 1500 places it among the more aerodynamically efficient trucks in its class. This efficiency is largely attributed to thoughtful engineering and the integration of active aerodynamic elements.

How Ram Trucks Achieve Low Drag

Modern Ram trucks incorporate various design and technological features to minimize air resistance:

  • Active Grille Shutters: These automatically close at higher speeds to redirect airflow over and around the truck, reducing drag. When the engine needs more cooling, they open.
  • Active Air Dam: This deployable air dam extends downwards at certain speeds to improve underbody airflow, preventing air from building up beneath the truck, which can cause drag.
  • Optimized Body Contours: The overall shape of the truck, including the windshield rake, roofline, and bed design, is carefully sculpted to smooth airflow over the vehicle.
  • Side Steps and Wheel-to-Wheel Design: These elements are often designed not just for utility but also to manage airflow along the sides of the truck.
  • Tonality Covers/Bed Covers: While optional, hard or soft bed covers can significantly improve a truck's aerodynamics by smoothing the airflow over the truck bed.

Benefits of a Lower Drag Coefficient

A lower drag coefficient translates into several practical advantages for truck owners:

Aspect Impact of Lower Drag Coefficient
Fuel Economy Reduces the power needed to overcome air resistance, directly leading to better miles per gallon (MPG) and lower fuel costs.
Noise Reduction Less air turbulence around the vehicle results in a quieter cabin experience, especially at highway speeds.
Vehicle Stability Improves the truck's road-holding capabilities and stability, particularly in crosswinds or at higher speeds.
Performance Frees up engine power that would otherwise be used to fight drag, allowing for better acceleration and towing performance.
Reduced Emissions Improved fuel efficiency also means a reduction in CO2 emissions, contributing to a lower environmental impact.

For a vehicle like the Ram 1500, which balances robust capability with daily usability, achieving a low drag coefficient like .357 demonstrates a commitment to efficiency without compromising its core utility as a pickup truck.
