When looking into some of the most efficient cars on the planet , there is something they have in common : a low drag coefficient .

Not only does this mean they ’ ve been strategically designed and tested to the hilt , but the cars are as close as possible to the lowest level of resistance a car can have while on the road .

Though this was previously achieved by cars that were low slung , with spoilers forcing air in the optimal directions , many of the latest cars are getting much better at this .

The Tesla Model S is recorded at 0.208 , which , to put it into perspective , is higher than the optimal shape that achieves 0.045 . Nevertheless , the car and its sister Model X ( recorded at 0.25 ) have very efficient shapes .

And these are just some of the EVs that top the chart . The RS e-tron GT records 0.24 , Lucid Air Sapphire achieves 0.197 , and the Lightyear 0 is set to reach 0.175 .
