This tutorial is for a freeform generalized car model. It can be adapted towards specific models by using plan drawings in orthographic view and adding extra edge loops as needed. (NB - You'll need to enable Advanced menus for this tut - via Edit | Prefs)


Start with a basic cube.


Extrude outwards the hood and trunk volumes.
(Bonnet & boot for those more used to the U.K. terminology.)


Extrude upward the cab volume.

Scale car, move edges, etc. in order to make proportions more car-like.
Note window angles, roof line, body lines, cab profile, etc.
In addition to being shorter than the body, the roof also tends to be less wide as well.

Select edge ring (default hotkey "g") and connect (default hotkey "c") to create centerline.

W3D quadcar Step6.jpg

Move centerline edges as necessary to define shape a little better.
Note that on most cars, the front and rear windshields have some curvature.

W3D all quad car Step7.jpg

Add these edges to help define the lower body.
Can be done rapidly by selecting appropriate edge ring, hitting "3", and then connecting.

W3D all quad car Step8.jpg

Add these edge loops to help start the front wheel wells.

W3D all quad car Step9.jpg

I almost forgot. These edges must be added as well before doing making the wheel wells.
Don't forget to adjust where needed to maintain proper curvature on cab windshields.

W3D all quad car Step10.jpg

Select these faces and dissolve.

W3D all quad car Step11.jpg

Connect vertices on front and back corners to create diagonal edges.
(A second diagonal edge is in the front of the wheel well area.)
Making the edges may take more than one step.

W3D all quad car Step12.jpg

Connect the front and back diagonals created previously.

W3D all quad car Step13.jpg

Scale edge Radial | radial Z | Scale to point. Select same point as illustrated. Scale to 0%.
(Holding shift will make snapping to 0% easy.)
This is faster than two separate vertice flatten operations.

W3D all quad car Step14.jpg

Create edges inside wheel well (connect, cut, etc.) so that existing edge loops maintain continuity.

W3D all quad car Step15.jpg

Create these "control" edge loops on the cab area of the car.
Using slide twice makes placement easy.
First slide relative +/- 100%, then without deselecting slide distance desired amount.

Create another set of control loops as in the illustration.

W3D all quad car Step17.jpg

Create and place an edge loop as illustrated.

W3D all quad car Step18.jpg

Select edges and slide back as shown in illustration.

W3D all quad car Step19.jpg

Select these faces and repeat the same steps used earlier to make the front wheel well.

W3D all quad car Step20.jpg

Select faces as pictured and scale along Z axis.
(Faces on front inside of wheel wells are also selected but not visible in picture.)
This shapes the wheel openings.

W3D all quad car Step21.jpg

Select these edges and move on Y axis to further adjust wheel well shape.

W3D all quad car Step22.jpg

Loop cut along the centerline. Select the unfinished half and delete it.

W3D all quad car Step23.jpg

Select resulting centerline face, then switch to verts. Flatten verts along x-axis.
(This step works with my personal workflow as I've had problems with the virtual mirror.
It ensures centerline verts actually lie along the centerline when using a RMB reference.
If you find the virtual mirror to work better, you can adapt your workflow to use it.)

W3D all quad car Step24.jpg

Select centerline face again, mirror.

W3D all quad car Step25.jpg

Of course you would think that it would be done in the previous step.
As the smoothed preview here shows, this is definitely not the case.
(This is true if you plan on smoothing it later.)
Right now it would be a bit "nerfy" if smoothed.
Thus a couple more steps to go.

W3D all quad car Step26.jpg

Select all the faces inside the wheel wells and extrude region normal.

W3D all quad car Step27.jpg

Create these controlling edge loops.

W3D all quad car Step28.jpg

Select these faces. Extrude region 0 units. (Use tab entry and enter 0, or use shift to constrain.)

W3D all quad car Step29.jpg

Without deselecting faces from before, hit "l" (L, not 1). This will select the edge loops that go around the edges. Slide inward.

W3D all quad car Step30.jpg

Select the faces on the sides as shown. Extrude region outwards a small amount.

W3D all quad car Step31.jpg

Select edges shown. Slide so that edges move inward on the side.

W3D all quad car Step32.jpg

Create some more "control" edge loops such as the ones highlighted here.

W3D all quad car Step33.jpg

Let's see how it looks with basic wheels, a few more minor tweaks, and in smoothed preview.
Pretty good, isn't it? You can either use the model as it is for low poly applications, smooth a few times, or use it as the base mesh for a more detailed model. (Maybe the final result here will be the start for a later tutorial on modeling detailed cars in Wings 3D.)

After modeling cars this way a few times, it should become obvious as to how the mesh can be changed for different models.
