Vauxhall Signum I (Z03) gallery (2003–2008)

The Vauxhall Signum was launched in 2003 as an innovative executive car offering an alternative to traditional saloons and estates. Utilizing the long-wheelbase version of the GM Epsilon platform shared with the Vectra Estate, the Signum focused heavily on passenger luxury and versatility. Its standout feature was the innovative FlexSpace rear seating system, providing two individual multi-adjustable rear seats with substantial legroom, reclining backrests, and a folding middle section that could accommodate the Travel Assistant console with storage, cup holders, and an integrated coolbox. The engine lineup encompassed naturally aspirated 1.8 and 2.2 Direct petrol units, a 2.0-litre Turbo, and a 3.2-litre V6, while diesel options featured 2.0 DTI, 2.2 DTI, 1.9 CDTi, and a 3.0-litre V6 CDTi. In 2005, the Signum received a comprehensive facelift featuring a sharper front-end design, revised grille, upgraded dashboard architecture, and the introduction of an advanced 2.8-litre V6 Turbo petrol engine. The model was discontinued in 2008 ahead of the arrival of the Vauxhall Insignia.
