There is a big difference between the electric motor and combustion engine. So much so that in the automotive segment several research and testing are being made to occur the replacement of the combustion by the electric model, we already have several vehicles that hold this type of technology that is still considered recent.
The main difference is that the combustion engine is driven by fuel and electric motor receives electric energy and converts into mechanical energy. It turns out that the electric motor ends up having a much better performance than the combustion engine and generates power more efficiently as well.
The combustion engine has been widely used in the automotive segment and today is hard to find a vehicle that does not make use of it, and further studies will bring the development of these segments, we tracking to be aware of new technological resources available in the market.
