The Opel Signum is powered by a seven-strong range of gasoline and turbo-diesel ECOTEC engines, with 100 to 211 hp, three of which are new developments.

Pulling power output and smooth running are strengths of the new 2.0-liter ECOTEC turbo engine, which has maximum torque of 265 Newton meters. The four-cylinder is based on the proven 2.2 ECOTEC aluminum unit and has 129 kW (175 hp). The third new power unit in the series is also a descendant of the 2.2 ECOTEC aluminum engine generation, introduced approximately two years ago, and is the first gasoline direct injection engine from Opel. The 114 kW (155 hp) four-valve unit uses approximately six percent less fuel than a conventional manifold injection engine, yet it has 10 percent more torque at lower rpm and six percent more power.

Among the many technical innovations and optionally available for the Signum is the Bi-Xenon headlamp Adaptive Forward Lighting (AFL) system, the first dynamic curve light with a static bending light for intersections and turning situations, which will be available starting from the fall of 2003. Opel is also offering an orthopedically recommended Multi-Contour driver’s seat with electronic climate control and various adjustment possibilities.
The new Opel Signum comes with a comprehensive range of comfort and safety features as standard equipment including: air conditioning, front and rear power windows, central locking with remote control, full-size front and side airbags, full size head curtain airbags, and active head restraints for all front and rear outer seats. Opel is the first car manufacturer to offer active head restraints for the rear seats.
