We weigh every single part that we remove and install on our MX-5e and we are also weighing the whole car at various stages of the project. This enables us to accurately predict the final weight of our MX-5e project and ensure we are on track to meet our target weight of less than 1000kg. We are really hoping to get closer to 970kg though 😎 You can find all the component weights in this Microsoft Excel spreadhsheet.
To make it easier to weigh the heavier items and the car, we have developed our own vehicle scales.
On the 27th we weighed the MX-5e for the first time at 987.2kg. Having factored in all the bits we removed and added, we estimate that the original car weighed about 1021.5kg. This is with minimal fuel. A full tank of fuel adds another 40kg to this weight.
