With its “Sixteen” concept car that originally debuted in 2003, Cadillac is headlining the Amelia Concours d’Elegance. Powered by a 13.6 liter, V16 powerplant with 1,000 hp, the Sixteen measures in at 19-feet long and weights in at 5,000 pounds. The Sixteen was widely rumored to have come very close to production status and is part of the American automaker’s “Art and Science” design theme.

It is possible that the presence of the Sixteen concept is to gain some feedback for Cadillac as it plans a new flagship sedan. Several more classic models will be present as well including a 1949 Coupe de Ville, 1952 Convertible Coupe, 1953 Le Mans concept, 1958 Eldorado Biarritz, 1959 Cyclone, and the 2002 Cien concept.

“We wanted a super luxury flagship,” said Wayne Cherry, the retired Vice President of GM Design who led the Sixteen design project. “The Sixteen had to have a presence. We wanted it to be the ultimate expression of Cadillac; to reinstate Cadillac as a world leader in design and technology and a reminder of the heritage of Cadillac.”
