Opel Senator - Senator B

A new model, the Senator B (marketed without the "B" suffix), arrived in spring 1987, a long-wheelbase version of the Opel Omega. There was no Monza equivalent.

There were various versions of the Senator B: 12-valve 2.5 L and 3.0 L sized engines were released in 1987 along with a luxury "CD" model with the 3.0 L engine. The CD version boasted adjustable suspension, air conditioning, heated seats, trip computer and cruise control. The cars were available with either 5-speed manual or 4-speed automatic gearboxes. Senator as a luxury car had many options to choose among other were: leather seats, heated seats both front and rear, electronic air conditioning, LCD instrument cluster, BBS styled multispoke alloy wheels made by Ronal.

A 24-valve 3.0 L was introduced in 1989, generating 204 PS (150 kW; 201 hp) (compared with 177 PS (130 kW; 175 hp) for the older 12-valve version). This model was very popular with the police force in the UK, with several cars being supplied to upgraded police specification. The main feature of the new engine was a "Dual Ram" system, increasing torque at low engine speeds by means of a redirected air flow system engaged at 4,000 rpm.

Later in the model's lifespan, the 2.5 L was replaced by a 2.6 L Dual Ram, and the 3.0 L 12-valve was deleted in 1992. CD versions of the 2.6 L and 24-valve 3.0 L were available up to the model's withdrawal in 1993.

When the second-generation Omega was released in 1994, Opel considered that it was sufficiently represented in the upper end of the market by the top-specification Omega Elite. Consequently, the Senator was cancelled in May 1993 and not directly replaced.
