X-Steam is a steam-powered race car with a steampunk aesthetic. This casting features a movable front splitter, dubbed the "flip-lip" by its designer, Miguel López; the splitter can be adjusted upwards to allow the car to clear loops and downwards for display purposes. This was Miguel López's last design before he left Mattel.
The casting was retooled for its Hot Wheels id release, now featuring a different engine and steering wheel piece; the base was also significantly modified to accommodate for the RFID chip.
