Some analysis of ancient chariots provide that the Egyptians greatly improved the design of this vehicle. However, while they certainly did make improvements to certain parts of the chariot, it is arguable whether the Egyptian chariot was better, or simply designed for a different purpose and terrain than others in the Middle East. For example, the Egyptian chariot had a metal covering for the axes, which reduced friction, and this was certainly an improvement. Also, some wooden parts were strengthened by covering them with metal sleeves.
