==Design==
A standard Mini 4WD vehicle is made of plastic using a [[Body-on-frame]] design.  The [[chassis]] contains the primary components including the AA batteries, motor, gearing, propeller shaft, drive axles, and wheels.<ref>{{cite web |url=https://www.tamiyausa.com/blog/mini-4wd-chassis-types/ |title=Mini 4wd Chassis Types |publisher=[[Tamiya Corporation|Tamiya USA]] |access-date=2022-07-25}}</ref>  The body is purely decorative although some newer designs incorporate ducting to cool the motor.  The body and chassis are made from hard plastics like [[Acrylonitrile butadiene styrene|ABS]].<ref>{{cite web |url=https://www.tamiyausa.com/shop/132-pro/jr-dcr-01/ |title=Specifications |publisher=[[Tamiya Corporation|Tamiya USA]] |access-date=2022-07-25}}</ref>
