The term rice burner or rice car most often refers to automobiles (usually economy cars) that have the appearance of a customized or high performance car, but often have little or no functional modifications applied, such as an improved engine, suspension, or brakes. This practice is in contrast to the "stealth" or "sleeper" style of automotive modification, where a vehicle may have major internal modifications for greater performance, but the appearance remains similar to that of a stock model. Almost any vehicle can be modified in this manner, but the most common vehicles are usually the sport compact models from most major automakers.
