In short: While most executives focus on comfort, the Opel Senator's four-wheel-drive variant served a much more clandestine purpose. Engineered with a Ferguson viscous coupling, these specialized vehicles were utilized by British Forces Germany during BRIXMIS operations to collect technical intelligence behind the scenes.

The Opel Senator, a flagship executive saloon produced between 1978 and 1993, was born from General Motors' effort to create common vehicle platforms. Acting as a successor to the failed 'KAD' luxury series, the initial model was a long-wheelbase iteration of the Opel Rekord E. While the Senator was a high-end model for both Opel and Vauxhall, its versatility allowed it to be rebadged as the Chevrolet Senator in South Africa or the Daewoo Imperial in South Korea. The first generation was available as a fastback coupé under the Monza name. It was also sold in Yugoslavia as the Opel Kikinda after being produced under licence by IDA-Opel.

Beyond its luxury credentials, the Senator featured significant engineering advancements. In 1984, a rare supercharged diesel version called the Comprex was introduced by Irmscher, making it the only production car in the world to use that specific technique at the time. This experimental engine offered a 12 percent improvement in acceleration over the standard turbodiesel and provided 90 percent of its maximum torque from just 1300 rpm. The 3.0E variant was the fastest car Opel ever manufactured, reaching 215 km/h. This model also featured upgraded Bosch LE-Jetronic fuel injection.

The vehicle's most notable feature for intelligence work was the optional four-wheel-drive conversion. Engineered by Ferguson—the same firm that modified the Jensen FF—this system used a viscous coupling to create a 60/40 rearward power bias. This setup was specifically adopted by British Forces Germany for BRIXMIS operations, providing the traction necessary for technical intelligence collection missions. This specific four-wheel-drive system could be retrofitted to existing vehicles. It helped maintain the car's original handling characteristics while improving traction.
