Thanks to the long wheel base (2380 millimeters) and the short rear-overhang, the Signum2 looks exciting even while standing still. This impression is enhanced by the muscular wheel arches filled by large 19-inch wheels fitted with 245/35 R19 tires. Typical Opel styling features are the prominent C-pillar and the wide, continuous shoulders. The designers and engineers omitted a B-pillar above the belt line in order to give the car a coupé-like appearance. The front is dominated by the typical Opel trapezoidal grille and the three-dimensional vertical headlamps. Like the new Corsa and Speedster, the Signum2 features a crease in the center of the engine hood.
In the interior, natural materials and friendly colors make for a comfortable, up-market atmosphere. Getting into the Signum2 is very comfortable, particularly for the driver and front-seat passenger. Pull the door handle and the front seats swivel automatically towards the doorways. At this stage, the steering wheel is lowered into the instrument panel, which makes access even easier. When the driver has taken his seat and is facing the front again, the steering wheel, which is designed like the controls of an airplane, automatically moves up towards him. This also reveals a clear view of the customized display behind it, which shows important information about the car and the pictogram-like route instructions from the navigation system. More detailed road maps are displayed on the 7" monitor in the center console (16:9 format). The front-seat passenger is provided with a full-blown computer with Internet access, operated via an infrared keyboard. When the mobile office is not in use, the color monitor of the PC folds flat and disappears into the instrument panel. A touch of the finger is all that it takes for the display to emerge from its hide-away. Rear seat passengers will find themselves in a world of relaxation and entertainment. There are two DVD players with headphones and special video glasses in the center armrest for listening to audio CDs or watching films in cinema quality.
The Signum2 is powered by the prototype of an eight-cylinder direct injection gasoline engine. The so-called 'Global XV8' aluminum concept unit was developed by GM Powertrain in the United States. It has a capacity of 4.3 liters and generates around 220 kW/300 hp with maximum torque of 400 Nm.
