Mechanical engineers are responsible for the design and overall integration of the structure, systems, and functions of the vehicle under their responsibility (e.g., steering, suspension, brakes, axles, pneumatics, and hydraulics). They check and approve new components or systems developed by designers. They make sure components meet the targets in the specifications (functionality, durability, costs, standards, performance, etc.). They must also check that new concepts fit together and can be manufactured. They have the opportunity to work within a multidisciplinary team that includes enthusiastic and qualified engineers and technicians and to play a role in creating innovative ways to get around using electricity.
