The Senator A was last part of a joint model programme executed by GM in the 1970s to develop a common series of vehicle platforms for both its European brands (and also for the Holden brand in Australia). The first two product families of this strategy – the T-Car (Kadett C/Chevette) and the U-Car (Ascona B/Manta B/Cavalier) had already been released. The V-Car (or V78) platform would simultaneously provide the next-generation Opel Rekord, a replacement for the Vauxhall FE Victor, and a 'stretch' version to replace the unsuccessful 'KAD' cars, and act as a flagship for both Opel and Vauxhall.

The Senator therefore emerged as a long wheelbase version of the Opel Rekord E, complemented by a three-door fastback coupé version on the same platform called the Opel Monza, which was planned as a successor for the Opel Commodore coupé.

The Senator A and Monza were initially sold in the United Kingdom as the Vauxhall Royale (and Vauxhall Royale Coupé). Unlike other members of the joint Opel/Vauxhall model programme of the period, the Royale was simply a badge engineered version of the Senator with only detail differences from its Opel sister.

Following the merger of the UK Opel and Vauxhall dealer networks in 1982, the Opel marque was repositioned as a performance-luxury brand, and the Vauxhall Royale models were dropped in favour of the Opel Senator/Monza, coinciding with the "A2" mid-cycle facelift. This policy was reversed in late 1984, with the Senator reverting to Vauxhall branding for the 1985 model year, but the Monza remained on sale as an Opel until its discontinuation at the end of 1987.

The vehicle was also available in South Africa as the Chevrolet Senator until 1982, when it was rebadged as an Opel.[http://www.productioncars.com/gallery.php?car=15764&make=Chevrolet&model=Senator Chevrolet Senator] The Chevrolet Senator was fitted with a locally built version of Chevrolet's 250 inline-six (4,093 cc), with {{convert|132|PS|kW|abbr=on}}.{{cite book | ref = AR82 | title = Automobil Revue '82 | editor-last = Büschi | editor-first = Hans-Ulrich | publisher = Hallwag, AG | language = de, fr | pages = 250–251 | location = Berne, Switzerland | volume = 77 | date = 3 March 1982 | isbn = 3-444-06062-9 }} The post-1982 South African Opel Senator received Australian-built, six-cylinder engines. In Serbia, the locally assembled Senator received the 2.5-litre six and was badged the "Opel Kikinda".

The Senator and Rekord E were used as the base vehicle from which the Holden Commodore was developed for the Australian and New Zealand markets. The later VK Commodore was a hybrid between the two Opel cars, featuring the Senator's six light glasshouse grafted onto the Rekord E derived shell.

The engine range for the first phase of the model's life included the 2.8S and the newly developed 3.0E, which had {{convert|180|PS|kW hp|0|abbr=on}} and {{convert|248|Nm|lbft|0|abbr=on}} with fuel injection. The three-speed automatic transmission was Opel's own design introduced in 1969, and was manufactured in Opel's transmission plant in Strasbourg, it was modified to cope with the new and improved power outputs.

Opel's own four speed manual transmission was not up to the job and they turned to transmission producer Getrag, who installed their 264 four speed manual gearbox in the early four cylinder Monzas. This was replaced by the five speed 240 for the 2.5 and 2.8 engines, and the 265 gearbox for the 3.0E.

The straight-six engines were all of the Opel cam-in-head engine design, as used in the earlier Commodore models and originating from the 1.7 and 1.9-litre straight four engines first used in the 1966 Kadett and Rekord. Opel would stick with the CIH engine design up until the 2.4 Frontera in 1993.

With the 3.0 litre engine, the Monza was the fastest car Opel had built, capable of {{convert|215|km/h|mph|0|abbr=on}}, and 0–100 km/h (0–62 mph) in 8.5 seconds. In June 1981, the fuel injected 2.5E engine also used in the smaller Commodore was added to the Senator/Monza lineup.Automobil Revue '82, pp. 432–433 With {{convert|136|PS|kW|abbr=on}} it was very close to the now irrelevant 2.8 and its {{convert|140|PS|kW|abbr=on}}, and the 2.8S was discontinued in 1982.

The original Senator and Monza were facelifted in November 1982, although the Senator "A2" (as it is usually called) only went on sale in March 1983. In the United Kingdom, it was initially sold only as an Opel, before being rebadged as a Vauxhall in 1984. The A2 Monza was only sold as an Opel.

The facelifted car looked similar to its predecessor, with relatively minor changes: smoothed-off headlights increased in size, and chrome parts were changed to a matt black or colour coded finish. The car was much more slippery, with drag resistance down (from 0.45 to 0.36 $\backslash scriptstyle\; C\_\backslash mathrm\; x\backslash ,$).{{cite journal | ref= ED1 | journal=Le Moniteur de l'Automobile | page = 107 | title= Essai detaillé: Opel Senator 2.2i| trans-title = Detailed Test | last= Pirotte | first= Marcel | location = Brussels, Belgium | language = fr | volume=36 | number=813 | date=24 January 1985 | publisher=Editions Auto-Magazine }} The top of the range 3.0E received upgraded Bosch LE-Jetronic fuel injection.

Interiors were improved with an altered dashboard and the new instrument pack with larger dials used in the Rekord E2, and engines changed. Now, the fuel-injected straight-four {{convert|110|PS|kW|0|adj=on|abbr=on}} two-liter cam-in-head unit from the Rekord E2 was available, although with little fanfare; this and the 2.5 essentially replaced the Commodore which was itself quietly retired in 1982. Power of the 2.0 was soon increased to {{convert|115|PS|kW|0|abbr=on}}. In March 1983 a 2.3-litre turbodiesel (shared with the Rekord) became available, and a few months later ABS-brakes (hitherto only available for the Senator CD) became an available option across the entire Senator/Monza range. At the Paris Show in September 1984 the 2.5E was given a new LE-Jetronic Bosch fuel injection system; power inched up to {{convert|140|PS|kW|abbr=on}}. The 2.0E was replaced by the torquier 2.2E, still with the same max power. Only the 3.0E engine remained untouched, although its name was changed to 3.0i. On the transmission side, the Strasbourg-built THM180 three-speed automatic was replaced by a four-speed unit. For the 1985 model year, the digital instrument display introduced in the Kadett E was available on the top models, although buyers could opt for the conventional analogue dials as a delete option. The trim surrounding the windows was more blacked out than before as well, although ample chrome remained.Pirotte, p. 113 the four-cylinder models were never sold in Vauxhall form in the United Kingdom.

Shortly thereafter, in November 1984 a supercharged version (Comprex) was shown – at the time, the only production car in the world to use this technique. Going on sale in 1985, this very rare experimental version (1,000 units planned) were officially built by Irmscher rather than Opel.{{cite journal | journal = Quattroruote | title = Anteprima: Futuro Prossimo |trans-title=Preview: The Future is Near | language = it |date=January 1985 | volume = 30 | issue = 351 | publisher = Editoriale Domus | location = Milan, Italy | editor-first = Raffaele | editor-last = Mastrostefano | page = 61 }} The Comprex offered {{convert|95|PS|kW|0|abbr=on}} and a {{convert|172|km/h|mph|0|abbr=on}} top speed, and acceleration figures showed a twelve percent improvement over the turbodiesel.{{cite magazine | magazine = Tekniikan Maailma | ref = TM | date = 19 March 1985 | number = 5/85 | volume = 41 | issn = 0355-4287 | title = Comprex sarjatuotantoon | trans-title = Comprex for serial production | editor-last = Toivonen | editor-first = Rauno | publisher = TM-Julkaisu | location = Helsinki | language = fi | page = 33 }} Like the other Rekord and Senator diesels it had a pronounced bulge in the bonnet. The Comprex offered marginally higher power than the turbodiesel, but more importantly, 90 percent of the maximum torque was available from 1300 rpm. From September 1985 until the end of production in the end of summer 1986, a catalyzed version of the 3.0E was available, with power down to {{convert|156|PS|kW|0|abbr=on}}.

A four-wheel drive conversion was also available, engineered by Ferguson, who had previously provided similar modifications for the Jensen FF. Rather expensive, this could also be retrofitted to an existing car.{{cite journal | journal = Automobil Revue '82 | title = Hat der Vierradantrieb eine Zukunft?/L'avenir des quatre roues motrices? |trans-title=Does four-wheel drive have a future? | last = Frère | first = Paul | language = de, fr | page = 101 }} The system uses a viscous coupling to distribute power with a 60/40 rearward bias, to improve traction while maintaining the Senator's handling characteristics.{{cite magazine | magazine = Autoweek | last = Kacher | first = Georg | page = 8 | date = 24 August 1981 | title = All-wheel-drive Senator | issn = 0192-9674 | volume = 31 | number = 34 | publisher = Crain Press Inc. }} These were used by British Forces Germany under the BRIXMIS (British Commanders' in Chief Mission to the Soviet Forces in Germany) operations for the collection of technical intelligence. The same kit was also used by Bitter Cars for a four-wheel-drive version of their SC coupé, beginning in the end of 1981.

A limited edition convertible edition was also available in Germany, where the company "Keinath" reinforced the car heavily, and this added to the all round weight to the car.

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

There were various versions of the Senator B: twelve 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 Electronic adjustable suspension, "ERC", for the first time in a mass-produced European car, air conditioning, heated seats also in the back, genuine walnut panels, leather covered centre console, trip computer and cruise control.

The cars were available with either five speed manual or four speed automatic gearboxes. A digitally controlled 4-speed automatic from Aisin-Warner equipped with three different switching programs Sport, Economy and Winter.

It was also equipped with torque delay at each shift, called "torque retard", for not notable gear changes. In winter mode the car starts on the third gear and switches immediately to fourth as soon as possible to prevent spinning wheels and instability. This mode remains to the speed of 80 km/h and then automatically switches off. The gearbox also had built-in diagnostic system and emergency program. Later Lexus and Volvo used similar versions of this transmission. As a luxury car, there were many options, but much was also standard. Options included leather seats, heated seats both front and rear, and electronic air conditioning including refrigerator in the glove box.

LCD instrumentation was also an option. Digital electronic power steering ZF-Servotronic, the same as in the BMW 7 Series, was standard, as was a new front axle design which allowed the axle to slide under the car in a crash and thus increasing the length of the deformation zone and prevent deformation of the footwell. The 3.0 24V was equipped with BBS styled multispoke alloy wheels made by Ronal.

A 24-valve version of the 3.0-litre six was introduced in 1989, generating {{convert|204|PS|kW hp|0|abbr=on}} – compared with {{convert|177|PS|kW hp|0|abbr=on}} for the older twelve valve version. This model was very popular with police forces in the United Kingdom, with several cars being supplied to multiple forces with upgraded police specification for traffic policing service, with the notable exception of the Metropolitan Police.{{cite book |last=Anstead |first=Ant |author-link=Ant Anstead |title=Cops and Robbers: The Story of the British Police Car |date=2018 |publisher=HarperCollins |location=London |isbn=978-0-00-824451-4 |url=https://books.google.com/books?id=eDTuAQAACAAJ |pages=154–155 |access-date=29 August 2023}} 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 which engages at 4,000 rpm. The engine in police service was capable of a speed of up to {{convert|140|mph|kph}}, although the bonnet was prone to rippling at such high speeds.

Opel tuners Irmscher introduced a 4-litre version of the Senator and it went on sale in Germany only in late 1990. Power increased to {{cvt|272|PS|kW|0}}, it was equipped with a body kit and alloy wheels, while the car's interior benefitted from buffalo hide, added wood panels, and lots of power equipment.{{cite magazine | ref = CC91 | title = Opel Senator i dyr kostym | trans-title = Opel Senator in an expensive suit | language = sv | magazine = Teknikens Värld | publisher = Specialtidningsförlaget AB | location = Stockholm, Sweden | page = 22 | date = 24 January 1991 | issue = 2 | volume = 43 | editor-first = Claes | editor-last = Johansson }} For 1990 the 2.5 L was replaced by a 2.6 L Dual Ram. The twelve-valve, 3-litre version was deleted from the range in 1992. CD versions of the 2.6 L (UK market only), and a 24 valve 3.0 L were available up to the model's withdrawal in 1993.

With the second generation Omega presented at the end of 1993 and available for sale from March 1994, Opel considered themselves sufficiently represented in the upper end of the market by the top specification Omega B. Production of the Opel Senator B ended in the autumn of 1993 with only 69,943 cars produced since the car's launch six and a half years earlier. Annual production had slumped from 14,007 in 1990 to 5,952 in 1992, with only 2,688 cars produced in 1993.{{cite book |chapter=Opel Senator B (1987–1993) |pages=323–325 |title=Deutsche Autos seit 1990 |trans-title=German cars since 1990: Audi, BMW, VW and smaller series |isbn=3-613-02052-1|first=Eberhard |last=Kittler |publisher=Motorbuch Verlag |location=Stuttgart |language=de |date=2001}} Following the announcement of the discontinuation of the Senator, the government of the United Kingdom would order a final batch of around 200 Vauxhall Senators in 1993 for diplomatic and policing use prior to moving over to the Vauxhall Omega.
