This concept car was created without image references.Only what I used was my car sketch from side view.I have huge car design visual library,so this model has the elements from well known concept cars and maybe from real production cars.

Model was created with blender3d 2.69,rendering preview images with cycles rendering engine included in blender3d.For blender file there is also model with standard materials.Tire treads were created from bunch of polygons.Some parts detached named by materials and objects.There is no need for textures for this product.For the final render I've been using studio hdr images,not included with final product.Model exported as subdivision 1,until my preview renderings created with subdivsion 2.There are no interior objects for this 3d model.On preview images you can see some color variations,so if you like you can create it in color variations you like.Enjoy my concept I hope you will be pleased by using this model in your scenes.
