Nice EV concept car model, very stylish and futuristic .
It just very basic car body modeling, no lights, doors, wheels, etc. Less polygons, I only use Crease=1 to represent sharp edges. Easy to alter the shape to your taste, allowing you developing the styling further, adding lights, intakes, altering the proportion and so on.
3D printable model, watertight surface, no gaps between faces and edges.
Checked with Repitier-Host printing software.
Model was created in 3dmax, render with VRay, files include.
