Opel prepared itself for the Euro 4 Emission standards and introduced a facelift for Vectra's second generation in 2005 for the entire range.
The German carmaker stayed true to its values and offered the Vectra a choice of three bodies: a sedan, a liftback (named GTS), and a station wagon. As usual, the hatchback, or liftback, was the middle road between the other two bodyworks, offering a bigger trunk than the sedan and a sportier look than the wagon.
Opel redesigned the entire front fascia. It didn't make just some small changes. There was a new pair of headlights swept-back over the hood and front fenders and a new grille. Its bumper sported new side scoops and raised outer sides. But the changes stopped there. The long greenhouse with a sloped tailgate remained the same, having the standard rear window wiper. The only difference was that the wiper was blade-style, not with the old system with brackets. Opel didn't change the taillights nor the chromed trim from the trunk.
Inside, the carmaker introduced a new infotainment unit with different buttons. Also, the instrument panel featured encircled dials and gauges. Another improvement was for the steering wheels, which received a new, three-spoke design and re-arranged buttons.
Under the hood, the GM installed a few new engines. Part of them, such as the 1.8-liter, was already Euro 4 compliant, but others were not. The most significant change was the introduction of the 2.8-liter turbocharged V-6, which replaced the older 3.2-liter unit built by Holden in Australia.
