When drawing a sports car, it's important to understand that there are many different kinds of sports cars. There's vintage, there's some made purely for speed, and some that are a bit more practical. Here are a few examples.
A sports car should look like it's in motion even when it's in park. These cars are built for speed, so they should like it. Notice how the body of a sports car is low to the ground and it has an aerodynamic design.
Let's start drawing our sports car by first laying down our guide lines. Draw these lines very lightly with a 2H or harder pencil so that they are easy to erase later on. These lines don't need to be perfect - they are just a guide.
We should first draw the grill of the car, which should be rather low to the ground. Make it interesting looking and be sure that it molds to the contours of the car by wrapping around the front end.
Working our way up the car, we can draw the hood and bottom edge of the front of the car. The hood can have large humps on either side that will make it look like air simply glides over it.
Let's continue working on the body of the car by drawing the side and rear end. Draw the wheel wells rather large, since sports cars have large tires.
Finish the contours of the car's body by drawing the roof and cab area. It should be very smooth and rounded.
Insert a large windshield and one large side window, since most sports cars do not have a back seat. Notice that the side window has a small piece of plastic or metal trim in the back corner.
Draw in miscellaneous details such as side mirrors, the door handle and lock, emblems, and the headlamps. Notice how the headlamps are very long and mold to the contours of the hood.
Finish the details by drawing aerodynamic grooves and humps along the body of the car.
Drawing the tires can by rather tricky. To do it properly, draw squares in the location of the tires. Then draw an X from corner to corner inside each square. Then, but using the intersection point of the X, draw another X in each square from top to bottom and side to side. This will find the center of each side of the square and act as a guide to create the circles.
To draw the actual circle, draw the lines of the circle through the points where the inner X meets the sides and tops of the squares. This will create properly proportionate circles, but they are not yet three dimensional.
To make the circles three dimensional enough to look like tires, use the above methods to create a partner circle next to your original circle. Then, draw a line from the top edge of the first circle, to the top edge of the new circle, as seen here with a green line. Do the same for the bottom of the circles.
Then darken the proper lines and erase all unneeded lines. You should now have disk or cylindrical shaped objects which resemble the basic shape of tires. Finish the wheels by drawing the rims. The lug bolts mount in the center of the tire and the arms of the rims reach out and hold the tire.
To add a greater sense of depth and dimension, shade the vehicle as you see fit. It’s a good idea to shade in the wheel wells, windows, and hollow parts of the and grill.
Finish off the illustration by inking it with a brush and ink or Micron markers. It's a good idea to use a ruler and a flex curve to get nice, clean lines. Once the ink is dry, erase the pencil marks with a kneaded eraser. You can add shine streaks to the windows with white ink or opaque white paint. And that's how you draw a sports car!
