Forty years of the Opel Omega A: the large Opel of a new era

In 1986, Opel introduced an entirely new top model for the upper mid-size segment: the Opel Omega A. This model succeeded the successful Opel Rekord and marked a clear break with the past. While the Rekord still had its roots in the 1960s, the Omega was developed as a fully modern business car for the second half of the 1980s. With an aerodynamic design, a spacious body, and a wide range of engines, Opel managed to create a car that was both comfortable and technically advanced. Shortly after its introduction, the Omega gained international recognition when it was named Car of the Year in 1987.

Development and design

Development of the Omega began in the early 1980s. The project was given high priority within Opel, and significant investments were made in research, development, and production. In total, the car's development would take several years and require an investment of billions of Deutsche Marks. Technically, Opel remained true to a classic design. The Omega featured a longitudinally mounted engine and rear-wheel drive, a configuration still common in this class at the time. The car featured independent suspension all around (rear: trailing arms) and was designed with comfort and stability in mind.

Aerodynamic

One of the key focuses during development was aerodynamics. At a time when many large sedans were still quite angular, the Omega featured a streamlined body with a remarkably low drag coefficient of around 0,28. This was particularly beneficial for a car of this size and contributed not only to improved performance but also to lower fuel consumption. The Omega was available as a four-door sedan and as a spacious station wagon, traditionally known as the Caravan in Opel's fleet.

Interior and equipment

Opel also took a step forward in the interior. The Omega offered a spacious interior with a strong focus on ergonomics and comfort. Depending on the model, buyers could choose from various equipment levels, ranging from relatively basic to very luxurious. Higher versions included features such as power windows, trip computers, air conditioning, and extensive upholstery options. Opel could also equip the Omega with ABS. In many European countries, the Omega became particularly popular as a company car and lease vehicle. The model was known for its comfortable handling, good high-speed stability, and relatively low running costs compared to some premium competitors. At the same time, the car's quality couldn't always compete with the more expensive versions in the business segment. Examples from the first few years were prone to rusting, electrical malfunctions were a common problem, and early models, in particular, weren't always free of creaking and rattling noises.

Facelift and technical innovations

In 1990, the Omega received a facelift that brought both visual and technical changes. Externally, the changes remained relatively subtle. The grille was modified, and details in the lighting and trim were also modernized. Furthermore, the facelift series was characterized by the use of more chrome. More significant were the changes under the hood and in the model lineup. A year before this update, the original 1,8-liter four-cylinder was discontinued, with the two-liter engine becoming the new entry-level engine. At the same time, new powertrains were introduced, including more modern six-cylinder engines. The introduction of a 24-valve version of the 3,0-liter inline-six, in particular, gave the Omega a noticeably sportier character. This engine produced over 200 hp and gave the large Opel performance that rivaled sporty models in the same class.

Engine range

One of the Omega A's strengths was its wide engine range. At the bottom end of the lineup were four-cylinder petrol engines, including versions with and without catalytic converters of the 1,8-liter and 2,0-liter engines. In 1988, the four-cylinder range was supplemented with the 2,4-liter engine. For the six-cylinder enthusiasts, three-liter versions were also available. Furthermore, the 2.6-liter inline six-cylinder engine was developed from this powerplant and debuted in 1990 (facelift). In addition to petrol engines, Opel also offered diesel variants. These became particularly popular with many drivers and taxi companies. The diesel was available with and without a turbocharger and had a displacement of 2260 cc. The diesels were further developments of the 2.3-liter diesel engine from the Opel Rekord E2.

Sporty variants

Although the Omega was primarily a comfortable business car, sportier versions also appeared. A well-known example is the Omega 3000, which was equipped with a powerful 3,0-liter six-cylinder engine. This version had a sportier appearance with a modified body kit, larger wheels, and a more sporty chassis. The absolute highlight of the first Omega generation, however, was undoubtedly the Lotus Omega. This special version was developed in collaboration with Lotus Cars and became one of the most extreme sedans of its time. The car was equipped with a heavily modified 3,6-liter six-cylinder engine with two Garrett T-25 turbochargers and an output of 377 hp. This allowed the Lotus Omega to reach speeds that even surpassed many sports cars of the time. With a top speed of approximately 285 kilometers per hour, the model was considered one of the fastest production sedans in the world in the early 1990s. Only the Alpina B10 achieved more impressive performance.

End of the first generation

Production of the Omega A continued until 1993, with deliveries ending in April 1994. Opel then presented its successor, the Opel Omega B. This second generation built on the foundation of its predecessor, but featured a more modern design and new technology. Today, forty years after its introduction, the Omega A is considered by enthusiasts to be an important step in Opel's history. The model combined classic rear-wheel drive with modern aerodynamics and a wide engine range. This allowed the Omega to develop into a strong representative of the large European business cars of the 1980s and early 1990s.
