Owning customised construction facilities is the hallmark of a top F1 team. The benefits of facilities are tremendous. Computer Aided Design (CAD) systems cut down the time involved in all Design work, while Computer Aided Manufacturing (CAM) systems save Engineering time. A Carbon-Fibre Unit enables you to build your own in-house Internal parts; as does a Manufacturing Unit with in-house External parts. Using a Testing Rig will improve your car's overall performance, while building a Wind-Tunnel will save you having to rent one whenever you need an indication of how fast your car is.
