As all drivers will know the older a car is the more maintence it will require. Petrol and diesel engines have a lot of moving parts and need to be serivced regularly. Oil and filter changes, spark plugs and leads, head gaskets and gearboxes all require regular up-keep and investment to keep them running smoothly. An electric car has fewer moving parts, so naturally this means fewer things to go wrong.
Electric cars also have regenerative braking systems. Regenerative braking systems help to charge the battery while a car is in motion and this increases the range of the battery between charges. By having this technology it means there is less wear and tear on an electric vehicles brakes than there is on a typical petrol or diesel vehicle and as such this means lower overall repair costs.
One thing that will still be comparible between traditional internal combustion engined vehicles and electric cars and vans, is tyre wear. Tyres will need to be changed regularly.
Many leasing companies and manufacturers offer maintenance packages for an additional cost to help cover any unforseen maintenance issues.
