Most Hot Wheels track sets are labeled for ages 4 and up; some playsets and race sets list age ranges such as 5–8 years.
Common inclusions are connector pieces, curved or loop track sections, launchers, and often one Hot Wheels vehicle for immediate play.
Most Hot Wheels track sets are non-powered, but a few include motorized or battery-powered elements. One listing specifies it requires four D alkaline batteries (required, not included).
Many Hot Wheels track sets and vehicles are 1:64 scale; some accessory or refill packs are labeled "Not to Scale."
