It is hosted by RC, but Rex will be 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).
Rex, Andy Davis’s insecure Tyrannosaurus Rex toy enjoys playing with RC Racer almost as much as he likes playing video games. With help from his Triceratops friend Trixie, Rex will invite guests to climb into RC for a thrilling ride on the U-shaped track. With Rex at the controls, RC Racer, with guests aboard, zips forward and backward at ever increasing heights and exhilarating speed.
