The Opel Insignia is a large family car (D-segment in Europe) developed and produced by the German car manufacturer Opel since 2008. Taking its name from a 2003 concept car, the model line serves as the flagship Opel car line, slotted above the Astra and Corsa in size. The Insignia serves as the successor for both the Signum and Vectra model lines, replacing both vehicles under a single nameplate. Currently in its second generation, the model line is offered in four-door sedan/saloon body styles, five-door liftback, and as a five-door station wagon/estate.
