What is the drag coefficient of the Toyota Avalon?
3 Answers
The drag coefficient of the Toyota Avalon is 0.27cd, which is quite advantageous for a family car positioned in the B+ segment. Taking the 2021 Toyota Avalon as an example, it is classified as a mid-size car with the following dimensions: length 4975mm, width 1850mm, height 1450mm, and a wheelbase of 2870mm. It has a fuel tank capacity of 60 liters and a curb weight of 1595kg. The 2021 Toyota Avalon features a MacPherson strut front suspension and an E-type multi-link rear suspension. It is equipped with a 2.5L naturally aspirated engine, delivering a maximum horsepower of 209PS, a maximum power of 154kW, and a maximum torque of 250Nm, paired with an 8-speed automatic transmission.
The Avalon is rock-solid on the highway, with an official drag coefficient of just 0.27 – absolutely top-tier in its class. During my test drive, I noticed how aggressively low the front end sits, with nearly flat side windows and even streamlined side mirrors. The real game-changer is the near-full underbody coverage – at 120 km/h the cabin stays library-quiet. Though some owners complain the underbody panels trap mud during car washes, this design requires regular cleaning to prevent cooling issues.
Recently, while researching the Avalon, I discovered a little-known fact: its slightly upturned rear end actually helps with airflow guidance! The car also has an underbody panel to streamline turbulent air. It's these meticulous details that contribute to its 0.27 drag coefficient. My buddy who drives this car on long trips says it saves half a liter per 100km compared to the previous model, probably because the smooth airflow reduces engine strain. If the active grille shutter (available on some trims) worked more diligently, highway fuel efficiency could improve even further.
