This five-door car is difficult to attribute to a particular class. Opel Signum has too long wheelbase for a hatchback, very short rear overhang for the station wagon and low roof and small size, only five seats, for a mini-van. Also it could not belong to representative class, though the place on the second row is not less than in cars of S-class. So, the release of Opel Signum launched a new class, which obviously was not expected. On the other hand ii doe not have anything revolutionary: base of Vectra III was stretched by 130 mm and completely revised the stern of the car. When looking at the Opel Signum in profile it clearly shows that the shape of a pillar has the letter "C" form. Emphasis is placed on the wide rear side door and huge lanterns which are flanking the vehicle.
Continuing the comparison Opel Signum with Vectra, it is notable the appearance of the original bumper which is a continuation of the radiator grille, which, incidentally, was also altered it. It is now painted in the body color and has a "honeycomb" insertion. The square fog lights were transformed into rounded. The center console and the instrument panel were inherited from Vectra. The rear seats are separate (in the ratio 40:20:40), can be folded independently of each other and have almost the same control as the driver: each can be moved between 130 mm and change the angle of the backrest to the 30 °. When handling the seats do not need to dismount the headrests. Trunk of the vehicle in the normal position provides 365 liters useful volume and with rear seats folded up to 1410 liters. If the cargo will be much longer, he front right seat can be overturned back. Then inside the Opel Signum calmly fit folded three-meter carpet.
However, a comfortable passenger compartment and a huge trunk are not the only innovations in Signum. The new 2.2 Direct Ecotec direct injection is one more reason to be proud. 155 horsepower calmly pull 1480 kg curb weight. Initially, however, persistence of the engine is slightly annoying, but after a while, we even see this as a grain of truth. With this delay it is very easy to switch to a higher gear without the familiar jerks.
