3. Hummer H2
Cd value: 0.57
Hummer H2 has been produced from 2003 to 2009. It is a large heavy SUV vehicle, more suitable for the off-road adventures (where it has shown as a decent vehicle) than for any other use, and therefore has many bad reviews. That is one of the reasons why there was only one Hummer H2 generation produced. Some “flaws” of this car are: huge fuel consumption, poor quality interior (having in mind the price of the vehicle), the wideness of the vehicle, tight cargo space compared to the size, etc. And in the end, bad aerodynamic shape, but being huge military like, slow off-road vehicle, that wasn’t designers’ primary concern.
