From 1995 the series was equipped with improved disc brakes, now with internally ventilated discs. More comfort was provided by a central locking system with infra-red remote control, including an integral immobilizer. The exterior mirrors were heated. The last examples of the G 500 limited edition left the production lines during the course of 1995, and by then it was no longer the most powerful G-model: this honour went to the G 36 AMG, which featured a larger displacement version of the engine in the G 320, generated 272 hp (200 kW) and was capable of 190 km/h.
In 1996 the G 300 Turbodiesel (177 hp/130 kW) replaced the G 350 Turbodiesel. The electronically controlled five-speed transmission was initially reserved for the new model, and Mercedes-Benz also presented the convertible variant with an electro-pneumatic roof. New features of the third model upgrade for the 463 series included a headlamp cleaning system and an aspherical mirror on the front passenger side. The diesel version was given cruise control, and the dashboard now featured a bulb failure warning lamp for the vehicle lights.
In 1997 the new V6-engine replaced the venerable in-line six-cylinder in the G 320, and the automatic transmission previously reserved for the G 350 Turbodiesel also became available for this variant. The following year saw the G 500 as the new flagship model, and part of a regular production series. With an output of 296 hp (218 kW) this was the first G-model to exceed the 200 km/h mark. All three engine versions were available as a short or long wheelbase station wagon, and as a convertible. The G 500 was also particularly well appointed, with electrically adjustable front seats, white indicator lenses, improved, internally ventilated front disc brakes, leather upholstery and burr walnut trim. Options included a parking aid, a navigation system, fixed telephone installation and heated rear seats.
In March 1999 the 20th anniversary of the G-Class was celebrated in Graz. This birthday was marked with a limited edition of 500, the G 500 Classic. Its luxurious appointments included special almandine black metallic paintwork, a two-tone nappa leather interior, exclusive wood trim, bumpers painted in the exterior colour and "Classic" lettering on the side mouldings. In summer 1999 the other models in the 463 series also received the multifunction steering wheel of the other Mercedes saloons.
Since its production launch in 1979, the G-Class has also been available with special protection in the models 280 GE, 300 GE and 500 GE. Since 1991 only the G 500 has been available as a GUARD version with special protection.
In 2000 the G 300 Turbodiesel was replaced by the G 400 CDI with its eight-cylinder diesel engine (250 hp/184 kW). The already extensive appointments were upgraded further, e.g. with the COMAND display system including navigation, radio, CD-player and telephone, a rain sensor, headlamp assist and automatic climate control. One year later the G 270 CDI was added (156 hp/115 kW). Since 2001 the G-Class has also been equipped with the Electronic Stability Program ESP®, 4ETS and Brake Assist, offering a unique combination of highly effective traction and handling safety systems, thereby improving both road safety and off-road capability even further.
From November 2001 the G-Class also became officially available in the USA – and encountered an unexpectedly welcoming market for this off-road classic, which served to increase the production volume of the G-Class significantly. In 2003 the decision was also taken to launch the G 55 AMG as the flagship model. Its eight-cylinder power unit had an output of 354 hp (260 kW), and the top speed was electronically limited to 210 km/h. Based on figures for 2008, the largest market for the G-Class was Germany, with a share of 30 percent, followed by USA, with around 20 percent. The diesel share amounted to approximately 40 percent. In the USA only the long station wagon G 500 and G 55 AMG were offered initially, later also the G 55 AMG Kompressor. Since the market launch of the G-Class a total of 200,000 vehicles have been delivered to customers worldwide.
The 25th anniversary of this classic Mercedes-Benz off-roader was celebrated in 2004. It was marked by a special "Limited Edition" for Germany, and by the identically engineered "Classic 25" for the world market. The G 55 AMG Kompressor
(476 hp/350 kW) was also presented, and all long-wheelbase models were given window bags. The V8 petrol engines now complied with the Euro 4 standard, the suspension setup of the more powerful models was revised and the steering gear was improved. There were other, safety-related changes, including a three-point seat belt for the rear centre seat of the long station wagon. The short station wagon and convertible were now offered as four-seaters, i.e. without a centre seat belt for the rear seat unit.
An important decision was taken in 2005, after no less than 26 years in production, namely to keep the G-Class in the Mercedes-Benz model range. This was preceded by careful thought on whether and how this unique vehicle could be retained in the light of changing registration requirements, e.g. on issues of pedestrian protection and exhaust emission standards. The decision was greatly aided by the fact that the
G-Class continued to enjoy great popularity worldwide. More than 185,000 units had been produced in Graz since 1979.
In 2006, its 27th production year, the G-Class was once again upgraded for the future. That year saw the launch of the G 320 CDI, with an ultra-modern diesel engine (224 hp/165 kW) and a diesel particulate filter as standard, which likewise met the stringent EU4 exhaust emission limits. The engine was combined with the 7G-TRONIC seven-speed automatic transmission. The G 320 CDI replaced the
G 270 CDI and the G 400 CDI. Other standard appointments included bi-xenon headlamps and fog lamps with the cornering light function. The four-door station wagon featured ISOFIX child seat attachments in the second seat row. Another new feature was the scratch-resistant external paintwork in calcite white, periclase green metallic and teallite blue. The attractive and highly resistant "ARTICO" interior package was available on request. The seats and door panels were lined in a particularly hardwearing, breathable and comfortable man-made leather material, while the floor covering was of robust, easily cleaned plastic.
In July 2006 the output of the high-performance engine in the G 55 AMG was increased to 500 hp (368 kW); with a maximum torque of 700 Newton metres. This made for exceptional performance: the off-roader accelerated from 0 to 100 km/h in just
5.5 seconds, and the maximum speed is electronically limited to 210 km/h.
In spring 2007 the G-Class underwent a model refinement. New accents in the interior were provided by a new instrument cluster featuring four analogue dials surrounded by chrome rings. The four-spoke multifunction steering wheel also had a new look: leather-clad as standard in the G 320 CDI, and in a wood/leather design in the G 500 and G 55 AMG. All three models had a modified centre console with new controls and switches for the air conditioning system and comfort functions. This not only improved the appearance of the cockpit, the new layout also improved operational safety. The COMAND APS control and display system came as standard in the G 500 and
G 55 AMG models and as a special equipment option in the G 320 CDI. New special equipment features were also introduced as part of the model refinement package, including for example a reversing camera and tyre pressure monitor. From the outside the facelifted G-Class generation was immediately recognisable thanks to LED rear light clusters.
Once again a special G-Class vehicle was delivered to the Vatican. In December 2007 the company handed over a new Popemobile based on the G 500. The head of the Catholic church had requested an open presentation vehicle for use in clement weather. It was equipped with a folding front windscreen and handrails, and like its predecessors it was painted in Vatican mystic white. The Holy Father entered the
white-trim interior of the cabriolet via a set of red-trim steps in the rear and conducted his audience tours standing up so as to be easily visible to the faithful.
In May 2008 Mercedes-Benz announced another update for the G-Class. A new engine was now available for the G 500, the M 273 V8 engine now generating 388 hp (285 kW) from 5.5 litres of displacement and developing torque of 530 Newtonmeters. The latest model generation also caught up with and incorporated the latest telematics technology, with a Bluetooth hands-free system for mobile telephone as standard. A media interface was available as optional equipment, which allowed an external music storage device to be linked up with the off-roader’s onboard electronics and control system. From the outside, the G-Class could now be identified by its restyled three-fin radiator grille, with the G 500 sporting new-look 18-inch light-alloy wheels as an additional distinguishing feature. The facelifted G 55 AMG, which followed in June 2008, also had the modified radiator grille, although of course this model boasted new 19-inch AMG-styled light-alloy wheels. Its high-performance engine now developed 507 hp (373 kW). Another new feature in the G 55 AMG was the ESP®control system, which recognised dynamic acceleration more precisely than in previous models, thus optimising vehicle stability. In addition, the powerful G-Class was also available immediately equipped with Hill Start Assist.
Alongside the civilian variants of the G-Class there were the usual special equipment versions. In 2009, for example, the Australian army began taking delivery of a 6x6 version (all-wheel drive with three axles), an new concept designed to cope with special payload requirements. Like all G-Class models, this variant was also built in Graz.
