After the new W463 was introduced in 1989 with extensively updated chassis and revised front end, the production of W460 ended in 1991 and was replaced by W461.
The W461 is essentially the chassis of W460 with powertrain of W463 and retains the W460 body.
While W463 is catered to the consumers who seek more creature comfort and better driving dynamics, W461 is built specifically for military, public authorities, and non-governmental organisations.
That included the 24-voltage electrical system for W461.
The W461 for military, public authorities, and non-governmental organisations is too extensive and wide-ranging to list here.

During the 1990s, W461 was offered with 2.3-litre four inline petrol engine and 2.9-litre five inline diesel engine from 1992 to 2001.
From 2001 to 2014, the W461 model for military and public authorities were offered with 2.7-litre five inline turbodiesel engine and later with 3.0-litre V6 turbodiesel engine.
They were called G 270 CDI Worker (2001–2006) and G 280 CDI Worker (2007-2009) respectively.

Over the years, Mercedes-Benz had introduced the civilian version of W461, built in limited series and for limited period of time.
They targeted primarily the consumers who wanted the "stripped down" version and did not need the creature comfort.
The engine choice was often limited to one type, namely diesel engine, per series.
Those editions were named as PUR or Professional.

In 2009, Mercedes-Benz, celebrating the 30-year anniversary of G-Class, introduced G 280 CDI EDITION.30 PUR based on five-door long wheelbase station wagon.
The consumers could order theirs with "Off-Road Package 1" or "Off-Road Package 2".
The passenger compartment had four seats upholstered in hard-wearing fabric or vinyl, rubber floor coverings, spray-protected/water-resistant controls, drainage apertures in the footwells, and wood floor in the load compartment with load lashing lugs and rails.
The dashboard received new instrument cluster from W463 and dual air bags.
The climate control remained manually operated so were the window winders and locks.
The exterior received the flexible wheel arch flaring, protective grilles for headlamps, taillamps, and front turn signal indicators, a walk-on hood/bonnet for easy access to the optional roof rack, a towing lug attached to the front bumper, and two-section barn doors in the rear.

The success of limited series "EDITION.30 PUR" led to G 280 CDI Professional in 2009 and its successor, G 300 CDI Professional, in 2010.
Initially, G 280 CDI Professional was limited to five-door long wheelbase station wagon before the body variants were expanded to five different body variations: three-door long wheelbase panel van (Kastenwagen in German), five-door long wheelbase station wagon, two-door cabriolet, and two-door and four-door cab chassis truck (Pritschenwagen in German) for G 300 CDI Professional.
The production of the civilian variant continued until 2014.
However, the military variant continues to this day.
