So it's a series hybrid with no mechanical link between the ICE and the wheels. This means that the engine runs at about 5k rpm when it's charging and then it shuts off until the cap is drained beneth a specified voltage.
It's originally a build for the Shell Eco Marathon so the rules for the competition has set the limits for which components we can use.
