It is hosted by R.C., but Rex is the host in Shanghai and under the named Rex's Racers.
Situated at the back of Toy Story Playland amongst mature trees which double as overgrown bushes in the Toy Story universe, RC Racer is the main attraction of that section of the park and the park's third roller coaster when it opened in August 2010 at Walt Disney Studios Park.
The ride takes inspiration from Mattel's popular Hot Wheels line of toy cars, which come paired with the orange track as seen in the Toy Story films. Climbing aboard the huge remote-controlled R.C. car, riders are propelled forwards and backwards through the station building in a semi-circular "half pipe" of track, quickly building up enough speed to hit the top height of almost 80 feet (24 metres).
When Andy Davis’ away when he was young, the toys will play. Luckily, he set up his orange Hot Wheels set in his backyard just before he left… and no one loves playing with it more than Rex, the insecure Tyrannosaurus Rex.
With the help of his Triceratops friend Trixie, Rex is inviting guests to race day. After winding your way through a series of toy garages and race-pit buildings, find themselves a seat inside RC. Then, guests hold on tight as RC begins zooming forward and backward, seemingly breaking the laws of gravity while taking you higher and higher on the U-shaped track.
