So at lower speeds, aerodynamic drag ends up a lower proportion of overall drag.<br /><br />For a Challenger car at 100kph, aerodynamic drag is over 90% of the total drag. Around 50kph, it's perhaps 75% of the total drag. Below 30kph or so, aerodynamic drag drops so much that only about half of the drag on the car is due to aerodynamics (the other half is rolling resistance). So if the race is cloudier and slower, a lower CdA is still an advantage, but it's a less significant advantage overall. mostdecehttps://www.blogger.com/profile/17817140290262571411noreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-42114745316069416102017-09-30T15:19:39.941-07:002017-09-30T15:19:39.941-07:00Why would monohull cars be less advantageous in th...Why would monohull cars be less advantageous in the rain.
