Head Gasket

HW All Drivers Welcome 3/5  Card #167/250  Orange/Teal - 2026 Hot Wheels Mainline. Head Gasket is a fantasy casting whose body design is inspired by an engine block, with its name punning on the actual "head gasket" engine part. Its orange-and-teal colour scheme is tied to Mattel's International Day of Play promotion, dated 06.11.2026 right on the card. This card is numbered 3 of 5 in the HW All Drivers Welcome series, card 167 of 250. All Drivers Welcome is an inclusivity-themed series, and promotional tie-in cards like this one tend to become short-print collectibles once the associated event date has passed.
