Weight of batteries and motor

edited October 2013 in IET Formula 24+

Can anyone help. We are a new team and would like to know the weight of an individual battery, as well as the weight of the motor

Many Thanks

    Hi Beth,

    I've asked the team here at MIRA and we have the following weights;

    Battery = 11.48kg
    Motor = 5.24kg
    Motor Mount = 0.28kg

    Does this sound right or are we running with extra weight? Or are we running underweight???

    EDIT: Added Motor Mount weight.

  • Thanks that helps a lot. Do you know a rough weight of your car this year?
  • Our car was about 65kg (we never got around to weighing it in its Goodwood spec).

  • Our cars also weigh around 65kg without the batteries. I don't have the exact weight of the separate component parts but those given sound about what I can recall from physically shifting things around.

  • With batteries and motor, you should be looking at a mass in the region of 50-90kg. Anything too much more is a disadvantage, but not much.
    The key point is to make your vehicle from materials that are appropriate: you don't need a steel laddder chassis, but a you want something more sturdy than 3mm ply for the floor.
  • I have built two with my old school. One had the problem of being a kit car and therefore rather heavy. The other one was a trug. So ive never actually had the chance to build one from scratch. Thank you for your help, as a brand new engineering college there is a lot of expectations on our team this year
