Hot Wheels Mario Kart Rainbow Road GXX41 - 8-Foot Track

Hot Wheels Mario Kart Rainbow Road GXX41 brings the Rainbow Road course to a floor-sized toy raceway with five translucent lanes, lights, sounds, and two included karts. The track reaches 8 feet long and 24 inches high, giving the set a large footprint for a toy designed for children ages 4 and up.

Five Lanes Across Eight Feet

The Mattel GXX41 listing identifies the set as a 2021 release with an 8-foot course, five race lanes, and capacity for up to five Mario Kart 1:64 scale die-cast karts. Its electronic start gate controls the launch, while the finish gate displays the winning lane.

The layout can be assembled straight or curved. Banked turns, a wavy road section, pop-up obstacles, and a spinning Item Box randomizer give the gravity-fed raceway more structure than a basic single-lane track.

What Comes In The Set

The US Target listing records 30 pieces, two 1:64 scale die-cast vehicles, and overall dimensions of 16 inches high by 36 inches wide by 5.25 inches deep. The listed weight is 10.22 pounds, and adult assembly is required without tools.

The included karts are Mario and an exclusive King Boo. The set uses three AAA batteries for its electronic functions, and the batteries are not included. Mattel's product information lists the age grade as 4 years and up.

Space Power And Compatibility

The five-lane course is the main distinction between GXX41 and smaller Hot Wheels track sets. It allows simultaneous racing for as many as five compatible 1:64 die-cast karts, while the two included vehicles provide a ready starting lineup.

The set is battery-powered for its lights, sounds, countdown, and finish display, but the cars move through the course by gravity rather than a motorized booster. That design keeps the race mechanics simple, although the 8-foot length and 36-inch listed width require a large play surface.

Best Fit For Mario Kart Fans

At $127.99 on Target's page on 09/24/2026, the GXX41 sits above compact Hot Wheels race sets and offers a much larger course, five lanes, electronic race effects, and two themed vehicles. Its value is tied to multiplayer scale and the Mario Kart presentation rather than portability.

The verdict is straightforward: GXX41 suits children ages 4 and up who want head-to-head racing and have room for a long, elevated track. The 30-piece assembly, 10.22-pound weight, six required AAA batteries, and limited two-kart starting set define its practical limits.
