Fewer parts, fewer services, fewer repairs
A modern engine, which was built by the current Euro standards, consists of approximately 2500 parts. The effort for development, manufacture and assembly is correspondingly large. In an electric motor only around 250 parts in contrast, are installed. Accordingly, few parts must, if at all, to be serviced or replaced. At most, signs of wear can occur in the bearings of the rotating rotor. Defects in the winding of the stator, the stationary part of the electric motor, are extremely rare. «A car with a combustion engine has thousands of parts in the drive train, an electric car only hundreds – we’re talking about a factor of ten to one,» says the Allgemeine Deutsche Automobil Club ADAC.
No gears
With very few exceptions, e-cars do not have complex transmissions. They always drive in «first gear». In contrast to the combustion engine, the maximum torque is already achieved shortly after the start. An e-car can very rapidly accelerate even at low speed. Even small e-cars accelerate on sports car level.
Electric motors are simpler and more efficient
Electric motors are smaller than combustion engines of the same performance. For their production, less material is needed. Many parts are unnecessary in the e-car. There is no automatic start-stop, no clutch transmission, no catalytic converter, no particle filter, etc. E-cars are practically maintenance-free. Apart from brake fluid and coolant for batteries, nothing needs to be replaced. Electric motors are significantly more efficient than combustion engines. They work almost silent and vibration-free and encounter no emissions. The recuperation during braking reduces energy consumption and wear on the brakes.
