For a very basic LEGO car, you will need a minimum of 4 tires of the same size, 2 axles of the same size, and at least one long LEGO piece to connect them. LEGO also manufactures pieces like steering wheels, seats, windshields, and car doors that you may enjoy adding to enhance your car’s details.
LEGO pieces are small and can pose a choking hazard to pets and small children if they’re left lying around. If they’re left on the floor they might also be stepped on, which can be painful. Building on the floor will work, but keep an eye on your pieces to make sure they stay in a contained area.
If working with small children, make sure the children do not put the LEGO pieces in their mouths, as they are a choking hazard.
For the chassis you will need 4 tires of the same size, 2 rectangular axles of the same size, and a thin 4x12 plate (the long, thin LEGO pieces). For the body, you will need 2 2x2 bricks, 6 2x4 bricks, 4 1x2 bricks, 1 1x4 brick, 2 2x2 clear angular bricks, 1 LEGO windshield, and 1 LEGO steering wheel piece.
Make sure the axle pieces and tires fit together snugly. The tires should be secure, but still able to spin freely. Make sure your tires and base piece are proportionate. Tiny tires will not adequately support a larger LEGO car, and will impede speed and movement.
Snap the clear bricks to the top of the square bricks. Attach the pieces you just completed to the front end of your car. Make sure the end of the plate is flush with the edge of the pieces you attached.
Stack two 2x4 bricks together. Snap on the windshield piece. Attach this section to the plate just behind the piece you attached in Step 3.
Snap the 1x2 bricks to either end of the 2x4 brick. It should look a little like a short “u” when you’re finished. Position the steering wheel in the space between the 1x2 bricks. The piece should be on the back row of studs with the wheel facing you. Press into place. Attach this section to the base just behind the windshield section. Build the body of the car. You will need 1 2x4 brick and 2 1x2 bricks. Snap these together to form a “u. " Attach this section to the plate just behind the cab.
Stack the two 2x4 bricks. Snap the 1x4 brick to the back of this stack. Press the plate onto the 1x4 brick so that it hangs off the back of the structure a little. It should look like the little “wing” on the back of a sports car. Attach this section to the base just behind the body section.
The front edge of the front wheels should line up approximately with the front end of the base piece. The back edge of the rear tires should line up approximately with the rear end of the base piece. If the tires are obstructed, change the width of the base piece, or find two longer, matching axle pieces.
You will need 2 1x10 bricks with holes in the sides, 1 2x4 plate (thinner than a 2x4 brick), 1 8x4 plate, 1 1x4 brick, 1 2x4 brick, 1 2x2 brick, 1 2x8 brick, 2 Technic axles, 4 LEGO wheel rims, and 4 LEGO tires. [2] X Research source You will also need 2 rubber bands.
Snap the 1x4 brick to the very front of the chassis. Forming a “T” shape, snap the 2x4 brick to the middle of the plate just behind the brick you just placed. Snap the 2x2 brick to the very back of the chassis. Place it in the middle of the plate so there is 1 stud on either side. Attach the 2x8 brick so that it covers the last 2 studs of the “T” shape. The back of this brick should hang out over the back end of the chassis.
Wrap one rubber band around the finger and thumb of your non-dominant hand. Slip the other band through the center of band #1 and pull about halfway through. Slide one end of band #2 through the loop formed by its other end and pull to secure.
For this design, you will need 2 rectangular axles, 4 tires of equal size, 4 2x8 bricks, 8 2x4 bricks, 2 1x2 bricks, and a thin plate at least 2x4 (but a longer plate is better). You will also need one small party balloon. [4] X Research source
Attach the tires to the axles. Place an axle at each end of the car. Turn the body over. You should now have a car body that is 4x16 with the two 2x4 bricks on top and wheels on the bottom.
Snap the 1x2 bricks to the top of the 2x4 column. Place one at each end to create a little hollow in the middle. Attach the final 2x4 brick to the top of the column. You should have a small hole in the middle of the column near the top.
