1999 Opel Omega B (facelift 1999) Dimensions, Size & Specs

The curb weight of the Opel Omega B facelift ranges from 1530 kg to 1710 kg (3372 to 3769 lbs), depending on the engine variant and equipment level. The maximum permissible gross vehicle weight (GVWR) lies between 2080 kg and 2200 kg (4586 to 4850 lbs). This weight range reflects the robustness of the vehicle, balancing performance and safety with the styling and comfort expected from an executive sedan of that era.

The Opel Omega B facelift provides a generous luggage capacity of 530 liters (approximately 18.7 cubic feet) with the rear seats in their upright position. When the rear seats are folded down, this capacity expands to 830 liters (about 29.3 cubic feet), offering ample space for transporting larger items or extra luggage. This makes the Omega B suitable for long trips or everyday family use, ensuring versatile storage options within a sedan body style.

The ride height or ground clearance of the Opel Omega B facelift varies between 140 mm and 150 mm (5.5 to 5.9 inches), depending on specific model and suspension setup. This clearance strikes a balance between comfortable ride quality, suitable for urban and highway driving, and enough height to handle occasional rough patches or speed bumps without scraping the undercarriage. However, it is not designed for off-road use or extremely rugged terrain.

Yes, the Opel Omega B facelift fits comfortably into a standard garage. With a length of approximately 4898 mm (192.8 inches), width around 1775 to 1785 mm (69.9–70.3 inches), and height near 1450–1455 mm (57.1–57.3 inches), it remains within typical residential garage size limitations in many countries. It is advisable to check your specific garage dimensions, especially for width and length, but the Omega B’s sedan proportions generally allow for easy parking and maneuvering inside a standard single or double garage.

Compared to the first generation Opel Omega (Omega A), the Omega B facelift (1999-2003) shows a slight increase in size and refinement. The Omega A was generally shorter and narrower, with less interior and luggage space. The Omega B facelift improved cabin comfort with a longer wheelbase and enhanced aerodynamics, translating into more passenger and cargo space without dramatically increasing the vehicle footprint. This enhanced the Omega’s executive appeal and competitiveness in its segment.

When compared to similar executive sedans of the late 1990s and early 2000s, such as the BMW 5 Series E39, Audi A6 C5, or Mercedes-Benz E-Class W210, the Opel Omega B facelift holds its own in terms of dimensions. Its length of nearly 4.9 meters (192.8 inches) and a width of around 1.78 meters (70 inches) positions it competitively within the segment. While premium German rivals may offer slightly more refined interiors or additional technology, the Omega B was praised for its spacious cabin, balanced proportions, and a large trunk making it a practical choice in the executive sedan category.

The Opel Omega B facelift supports a range of tire and rim sizes based on the variant and trim options. Rim sizes include 15, 15.5, 16, and 17 inches with widths ranging from 6.0J to 7.0J (where 'J' indicates rim profile). The compatible tire sizes include 195/65 R15, 205/65 R15, 225/55 R16, and 235/45 R17. This variety allows owners to choose between comfort-oriented tires or sportier setups depending on driving preferences. The rim and tire combination also affects handling dynamics, ride quality, and visual appearance of the car.

The roof load capacity of the Opel Omega B facelift is rated at 100 kg (approximately 220 lbs). This means that you can safely mount roof racks, cargo boxes, or bicycle carriers without exceeding this weight limit. It is essential to adhere to this limit for safety reasons and to maintain vehicle handling characteristics. This roof load capacity enhances the car's practicality for outdoor activities, vacations, or transporting larger or bulky items that don’t fit inside the trunk.

The 1999 facelift of the Opel Omega B brought several notable improvements over earlier versions. These included updated styling with refined headlights, grille, and bumpers that gave a more modern, aerodynamic look. Interior revisions improved ergonomics and materials, enhancing comfort and luxury feeling inside the cabin. Mechanically, there were updates for better engine performance and reliability, as well as enhanced safety features such as improved airbags and ABS. These changes helped maintain the Omega’s competitiveness in the executive sedan market through the early 2000s.
