| |
| − | The goal of the powertrain is to move the car forward. In an internal combustion engine, this is accomplished by converting chemical energy stored in a combustible fuel source into mechanical energy. An internal combustion engine burns the fuel to create rotational energy. This is transmitted to the ground through the drivetrain.

| |
| − |
| |
| − | =Engine:=
| |
| − | As of 2019, the FSAE rules require an internal combustion engine with a displacement of 710cc or less. Available OEM motors within this displacement limit are largely sourced from motorcycles and snowmobiles.
| |
| − | =Intake=
| |
| − | All air used by the engine(s) for combustion must pass through a 25mm opening, commonly referred to as a 'restrictor'. For naturally aspirated engines, this restriction limits the maximum power output from the engine to about 100 hp.
| |
| − | =Exhaust=
| |
| − | The competition rules limit sound output of the engine.
| |
| − | =Fuel=
| |
| − | The fuels available at US competitions are gasoline of octane ratings 93 and 100, and E85.
