A recent test, which included the electric sedan next to other four cars for a thorough wind tunnel celebrated the start-up California-based automaker with having the most aerodynamic car on the road.
Even if you don’t know much about physics, it’s an easy guess that having a very aerodynamic car brings a growth in total efficiency, which is actually the strive of any automaker when trying to cut loses and increase mileage.
While many strive to achieve for various reasons only average aerodynamics efficiency, others go out of their usual business to reach certain thresholds. To put to the test some of the models who boast increased efficiency on the matter, a recent Car and Driver test brought together the Chevrolet Volt, Mercedes-Benz CLA 250, Nissan Leaf, Tesla Model S P85 and the venerable Toyota Prius to the wind tunnel.
Here, the aerodynamic drag of each was thoroughly measured, also bringing in for an official reference an older 2001 Honda Insight hybrid – which has an official drag coefficient (Cd) of 0.25.
The results were actually quite interesting, as the only two models that lived to their advertised official drag coefficients were the Model S – with 0.24 and Chevy’s Volt with 0.28. Toyota’s Prius came very close to what it said – with a 0.26 coefficient instead of the official 0.25. On the other three cars, the official ratings were missed by a mile: Leaf came with a tested 0.32 figure (official 0.28); the Insight was way off at 0.30 (against the stated 0.25) and the Mercedes was the worst – from the official 0.23 to the recorded 0.30.
