*The bullet depicted has a sub-transonic drag coefficient of Cd 0.147.
*In ground proximity,and sectioned longways to create a 'template',the bullet would have Cd 0.294.
* Adding wheels would get Cd 0.334- 0.344.
* It would have a lot of wetted area for its frontal area,and like your VW,without a tail,only mediocre Cd.
* The 'Template' would produce Cd 0.12-0.13,depending on wheels/tires
