DCA will be getting "Carsland" in last remaining piece of parking lot out back as part of the $1.1 billion makeover. It will include three attractions inspired by Disney-Pixar's Cars. One will be in the styling of the old Flying Saucers ride (

Finally the centerpiece will be the E-ticket level "Radiator Springs Racers" featuring a latest-generation Test Track style ride system allowing for head-to-head high speed "racing". Here's more info, plus concept art:

Anyway, Carsland will be entirely themed to Disney-Pixar's Cars and will resemble Radiator Springs. No other film tie-ins are planned at this time and would frankly look very out of place.
