The second generation of that car, from 1987, shared its base with the Rekord's Opel Omega successor, which was again lengthened to produce the Senator.

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.

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 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 180 PS (132 kW; 178 hp) and 248 N⋅m (183 lb⋅ft) with 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 110 PS (81 kW) 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.

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.

[7] At the Paris Show in September 1984 the 2.5E was given a new LE-Jetronic Bosch fuel injection system; power inched up to 140 PS (100 kW).

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.

[9] The Comprex offered 95 PS (70 kW) and a 172 km/h (107 mph) top speed, and acceleration figures showed a twelve percent improvement over the turbodiesel.

The Comprex offered marginally higher power than the turbodiesel, but more importantly, 90 percent of the maximum torque was available from 1300 rpm.

A four-wheel drive conversion was also available, engineered by Ferguson, who had previously provided similar modifications for the Jensen FF.

[11] 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.

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.

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.

A digitally controlled 4-speed automatic from Aisin-Warner equipped with three different switching programs Sport, Economy and Winter.

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.
