Downforce Racer

Geared car, Years 9-11

Your students learn engineering concepts from first principles as they make, modify and optimise this geared racing car. To get the most out of their vehicle a good understanding of friction, downforce, weight and gear ratios is needed, and this comes through making the car and putting ideas to the test. Measuring speed, and comparing it with weight and gear ratio is an important step in this process. This is where the data logger comes in.  And when your students think they have the best car, it’s time to race them against each other.

This project is rich with engineering content, backed up with a full set of teaching resources. The teaching resource pack includes CAD tutorials and examples ready to send to your CNC router.

Connecting cables to the motor

It might be necessary to slightly crimp the motor connector cables before pushing them on the motor terminals. This will ensure a good push fit.
