In 2015, the museum underwent extensive renovation. The building's façade was redesigned by the architectural firm Kohn Pedersen Fox, while designers at The Scenic Route configured interior spaces to accommodate changing exhibits that are intended to encourage repeated visits. The remodeled museum opened to the public on December 7, 2015.
The ground floor focuses on automotive artistry, showcasing an array of extravagant automobiles. The second floor is principally concerned with industrial engineering—including design, performance, and a collection of interactive teaching exhibits. Special displays on the industry floor cover racing, motorcycles, hot rods and customs. The third floor chronicles the history of the automobile with an emphasis on the car culture of Southern California.
