Check out This POV of the Radiator Springs Racers at Carsland, Disney's California Adventure! Radiator Springs Racers is a slot car dark ride attraction in Cars Land at Disney California Adventure. The attraction features third-generation Test Track technology, an attraction located at Epcot in Walt Disney World. Radiator Springs Racers is themed to the fictional world from Disney·Pixar's Cars. The attraction is the most expensive to be built in the entire Disneyland Resort, one of the most expensive attractions Disney has ever built, and one of the most expensive theme park attractions in the world at an estimated cost of over $200 million, which took up about 18% of the entire cost of the $1.1 billion expansion plan for Disney California Adventure Park. The attraction takes guests in a six-person vehicle[1] through a briefing with Doc and Lighting McQueen, characters from the film Cars. Guests race another guest vehicle through turns and banks, ending with a randomized race result. At the "What's Next?" presentation at Disney California Adventure on June 11, 2010, Imagineer Kathy Mangum gave a brief rundown of the storyline for the attraction. Walking past the courthourse, the queue goes through some of the original buildings of Radiator Springs when Stanley first opened his Stanley's Oasis business at the natural Radiator Springs that provided the town's name and enter the old hotel he set up in Taillight Caverns. Guests board their ride vehicle and are taken on an idyllic drive through Ornament Valley Range. The vehicle enters the dark ride portion of the attraction as guests nearly run into several Audio-animatronic characters. As the vehicle swerves out of the way, it encounters the Sheriff who appears as if he is going to issue a speeding ticket, but instead is impressed with the driving skills and invites the car to the town's big race. Before the race can begin, though, Mater has to take the vehicle for a round of tractor tipping. Suddenly, Frank the Tractor wakes up and chases the trespassers off of his farm. On the way back into town, the vehicle is prepared for the race. At this point, the vehicle will either turn to Luigi's Casa Della Tires for a tire change or to Ramone's House of Body Art for a quick paint refresh. From there, the two vehicles sit idle to one another at the starting point. After Luigi's word, the race begins through the remaining out-door portion of the attraction reaching the ride's top speed of 40 mph (64 km/h). The race finishes after the vehicles drop a sloped bank where guests have their on-ride photo taken.
