4. Mercedes Benz G class
Cd value: 0.54
This vehicle number four on our list of least aerodynamic cars ever made is one of the longest produced by Mercedes Benz, being introduced in 1979. Primarily made as mid-size SUV vehicle with great performances, during the time it upgraded looks, creating comfortable interior and modern engines that enable fast movement through the muddy and rough terrain. Being highly ranked in this vehicle class, this car is also very expensive, and adding to that, a real fuel devourer.
