This document provides specifications and calculations for designing a vehicle with a maximum speed of 50 kmph. It lists the vehicle's gross weight as 2943 kg, air resistance as 67.586 N, and tire radius as 0.27m. It calculates the vehicle's maximum tractive force as 1640.4 N, road load on flat ground as 1950 N, and maximum torque at the wheels as 431.07 Nm. It also provides details on gear ratios ranging from 18 to 6.312 and an acceleration range of 7.84 to 7.68 m/s^2. Finally, it includes a parts list with estimated costs and timelines.
