OPEL Signum 2005-2008 Photos, engines & full specs

After the dismissal of the Opel Omega in 2003, the German car-maker needed a new offer in the executive market and it came with the Signum, which was refreshed in 2005 along with the Vectra range.

The Opel Signum was the big flop on the German car-maker range. It was based on the long-wheelbase platform of the Vectra Station-wagon and, while the front was identical with its lesser brother, the rear was different but resembled the Opel/Vauxhall Astra, which was a compact hatchback. The 2005 refresh brought a new exterior look, new interior features, and a new engine.

From the outside, the most striking difference was on the headlights. The new parts were bigger and extended toward the A-pillar. The hood and the front fenders were changed. A wide chromed bar with the large Opel badge was the dominant feature of the grille.

Inside, the Signum retained its four-seats architecture with two separate places for the rear occupants. Due to its long roofline and 2.83m (111”) wheelbase, it offered plenty of legroom and headroom. There was a new, three-spoke steering wheel, new wood grains, aluminum, or carbon-look trims.

The engine lineup was completed with five gasoline engines (1.6 - 2.8 liter, 100 - 230 hp) and four CDTI common-rail types of diesel (1.9 - 3.0 liter, 100 - 184 hp). The top model was fitted with a turbocharged gasoline V6 unit. Apart from the base, 100 hp engine, which was fitted with a 5-speed manual, all the others were fitted as standard with a 6-speed manual. The 2.8 V6 Turbo, the 150 hp 1.9 CDTI, and the 3.0 V6 CDTI were available with a 6-speed automatic.
