remove as much space touching the surface which will cause friction.
A car will have aerodynamic features to reduce forces of friction and drag. A sleek body style will help do this.
Friction is de opposition of motion. if a car is in motion, the friction is said to be reduced because it oppose de movement of the car.

When car brakes are applied, they create friction between the brake pads and the wheels. This friction slows down the wheels, reducing the car's speed.
To reduce air friction.

The two types of friction that affect a mousetrap car are rolling friction, which occurs between the wheels and the surface of the ground, and sliding friction, which occurs between the axles and the wheels. Both types of friction can reduce the overall efficiency and speed of the mousetrap car.

Reducing mass and friction in a CO2 car can improve its overall speed and performance. With less mass to accelerate, the car can move more quickly, while reduced friction allows it to maintain momentum and travel farther. Both of these factors can help optimize the car's efficiency and competitiveness in a race.
Friction has two unpleasant effects: 1) it increases wear and tear, 2) it wastes energy.
Friction between the tires and the road can reduce the distance a car can travel because it creates resistance that opposes the motion of the car. The more friction there is, the more energy is needed to overcome it, which can decrease fuel efficiency and the overall distance the car can travel.
