Opel Insignia

The Opel Insignia is a large family car (D-segment in Europe) developed and produced by the German car manufacturer Opel from 2008 to 2022. Taking its name from a 2003 concept car, the model line serves as the flagship model, slotted above the Astra and Corsa in size. The Insignia serves as the successor to both the Signum and Vectra model lines, replacing both vehicles under a single nameplate. The model line was offered in four-door sedan/saloon body styles, five-door liftback, and as a five-door station wagon/estate.

Sold worldwide, the Insignia is marketed under multiple nameplates. Under Opel tradition, the model line is marketed by Vauxhall in the United Kingdom, taking on the Vauxhall Insignia name. Both generations of the model line have been marketed in the Americas as the Buick Regal (sales of the Regal continue in China), except in Chile, where the vehicle was originally due to be marketed as the Chevrolet Vectra, but went on sale as the Opel Insignia instead. GM Australia marketed the second-generation Insignia as the Holden Commodore through 2020 (until discontinuing both the model line and the Holden brand).

The launch vehicle of the GM Epsilon II platform, Opel produces the Opel/Vauxhall Insignia in Adam Opel AG Werk Rüsselsheim in Rüsselsheim, Germany. SAIC-GM produces the Buick Regal in Shanghai, China (exclusively for the Chinese market). In the UK, the Vauxhall Insignia bid farewell as the model was retired in 2022.
