From the Universal Studios Hollywood website, 2022
“Ready to experience Mario Kart like never before? Put on the special goggles and battle Team Bowser on iconic Mario Kart courses alongside Mario, Luigi, and Princess Peach. Collect coins and throw shells to win the Golden Cup on the world’s first interactive Mario Kart ride with cutting-edge technology at SUPER NINTENDO WORLD™. Opens early 2023.”
This attraction has been confirmed for Super Nintendo World, Japan (see video below, June 2017), and is believed to be the signature attraction that will be featured in the Hollywood and Orlando locations.
This attraction is believed to include augmented reality technology (‘special goggles’), and to merge this with a physical ride experience, using a track-mounted vehicle.
At some point during the ride, a tunnel lined with immersive projections will be used to simulate either an increase in speed, or a move to a different location.
