The Tesla Model 3 has a drag coefficient of 0.219, which is the lowest of any Tesla vehicle.[1][3] This represents a 5% improvement over the previous Model 3 generation, which had a drag coefficient of 0.23.[3][5]
The improved aerodynamics of the new Model 3 are due to design changes such as a more streamlined front bumper, smaller headlights, and a flatter hood.[3] Tesla has also made aerodynamic improvements to the rear of the vehicle, including a redesigned lower rear bumper with an air diffuser.[3]
While the Model S has an even lower drag coefficient of 0.208, Tesla claims the new Model 3 has the "lowest absolute drag of any Tesla."[3] However, the most aerodynamic production car on the market is the Lucid Air, with a drag coefficient of 0.197.[3]
The improved aerodynamics of the 2024 Tesla Model 3 contribute to a 12% increase in range on the WLTP test cycle, with the Model 3 RWD now rated at 344 miles and the Model 3 Long Range at 421 miles.[3] The enhanced aerodynamics also result in a 30% decrease in wind and ambient noise inside the vehicle.[3]
