The Cadillac Sixteen Concept was designed with crisp edged lines of the midnight silver aluminum body panels accentuate the model's exceptionally striking appearance.


      The Cadillac Sixteen interior included a Bvlgari clock, Steuben crystal accents, Tuscany leather seating, and hand-woven silk carpeting. The right-sided rear seating for occupants featured powered adjustable slopes to recline like a chaise lounge. The hand-woven silk carpeting was a light cream color that matched the leather upholstery. For a further rich contemporary styling, the interior dash, door panels, and front and rear console was offered with a trimmed walnut burl veneer inlay.


      The Cadillac Sixteen also offered GM's XV-16 cylinder concept engine that generated more than 1000 horsepower and 1000 lbs. ft. torque. The extensive use of aluminum components and structure provided substantial weight advantages. The aluminum steel chassis employed a high-arm SLA suspension up front and independent semi-trailing arm suspension in the rear.
