The coefficient of drag of the fifth-generation Toyota Prius is 0.27.
Toyota achieved this figure with the 2023 Prius, whose sharply sloping roof, smooth bodywork, underbody panels, and grille shutters help air flow efficiently around the car. The fifth generation was unveiled in November 2022 and introduced a more dramatic, lower-looking design than the fourth-generation Prius.
A coefficient of drag, or Cd, measures aerodynamic resistance: lower values generally mean less energy is needed to push a vehicle through the air. The fifth-generation Prius’s published 0.27 figure is associated especially with the LE specification and 17-inch wheels, though Toyota’s general product material also presents 0.27 as the model’s Cd.
A common mix-up is confusing this number with the fourth-generation Prius’s approximately 0.24 Cd. The newer Prius became more powerful and sportier in appearance, but its published drag coefficient rose slightly while its overall aerodynamic design remained highly efficient.
