When people talk of the teardrop shape they do not mean it literally. A water drop in mid-air wants to be a sphere due to surface tension, and water drops are very small so the surface tension forces are dominant.
Here is a "teardrop" shape:

.Cd,
That white camaro in your pictures has decals stuck to the front to give the appearance of headlights and the turn signals. For all I know the grill could be a decal too. So the front is a lot smoother than it looks.
