One of the most fascinating aspects of engine cams is their cam profile, which defines the shape and motion of the cam lobes. The cam profile directly influences how quickly and how far the valves open and close. A cam profile with a more aggressive shape will allow the valves to open wider and stay open longer, resulting in improved intake and exhaust flow at higher RPMs. This enhancement can lead to significant increases in power output.

Safety is another critical consideration in modern chassis design. Automotive manufacturers are implementing advanced safety features, such as crumple zones and reinforced passenger compartments, designed to absorb and dissipate impacts during collisions. The use of computer-aided design (CAD) and simulations has also improved the ability to predict and enhance safety performance before manufacturing physical prototypes.
