🏎️ 赛车 = 赛 (race/compete) + 车 (vehicle) = race car
赛 means to compete or race; 车 is the general word for a wheeled vehicle. Stick them together and you get the vehicle built for racing, or the racing event itself.
赛 — roof 宀 + 共 (together) + shell 貝
赛 originally meant offering thanks or recompense to spirits, written with 貝 (cowrie/money) suggesting tribute or payment. The upper part acts as the phonetic component. Over time the meaning shifted from ritual repayment to 'compete' or 'contest,' as in matches between rivals.
车 — pictograph of a chariot/cart
车 is a pictograph originally drawn as a top-down view of a chariot, showing the axle, wheels, and carriage box. The ancient form 車 clearly depicted two wheels connected by an axle. It still means vehicle, cart, or car today.
