GM Europe decided to introduce a facelifted version for the Signum after just two years since its launch on the market, but that didn't help too much.
When GM introduced the Vectra lineup, either as a Vauxhall or as an Opel, on the European market, it already had a plan to make it as a replacement for the Omega range as well. By using the same platform, it could cut costs and use the same assembly line. As a result, the Vectra appeared in 2002, and the following year Opel introduced the Signum. In 2005, Vectra was refreshed and, with it, Signum went through a mid-life cycle refresh as well.
With its new, swept-back headlights and the thicker chromed slat at the front, the 2005 Signum showed a sporty, yet elegant, front fascia. Vauxhall changed the hood and the front fenders as well.
Inside, the Signum retained its four-seat 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 carmaker completed the engine lineup 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). Vauxhall fitted the top model with a turbocharged gasoline V6 unit. Apart from the base, 100 hp engine paired 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. All engines complied with the Euro 5 European emission standards.
