Back to the Future

The case for streamlined cars isn't new - for decades, mankind has searched for higher top speeds, especially in racing. And because aerodynamics is by far the most dominant force to overcome at high speeds (even at highway speeds, over half the energy goes to pushing air away...), reducing the aerodynamic drag coefficient has been key...............................

So how did the Mercedes W125 beat the Veyron decades ago? You guessed it - aerodynamics. The aerodynamic power required to push the air away scales with the cube of velocity, whereas mechanical losses (like drivetrain and rolling resistance) only scale linearly with velocity. So at these speeds, aerodynamics easily account for over 90% of all energy needs.

The record-breaking Mercedes W125 - Drag coefficient Cd of 0.235

Ford Probe Y - Drag coefficient Cd of 0.137

Recent attempts have been made to make cars as aerodynamic as possible while still maintaining good looks, like the Lightyear One (featuring a Cd value "below 0.20") and the Mercedes EQXX (featuring a Cd value of 0.17!).
