The History Of Mercedes G400

For G-class stars, see Stellar classification.

The Mercedes-Benz G-Class or G-Wagen, short for Geländewagen (or cross-country vehicle), is a four-wheel drive vehicle / sport utility vehicle (SUV) produced by German automaker Mercedes-Benz. It was borne by proposals for a military vehicle in the early 1970s by the Shah Mohammad Reza Pahlavi of Iran, a major Daimler-Benz shareholder. Developed in co-operation with the Austrian car manufacturer Steyr-Daimler-Puch, production of the G-Class began in 1979 with the 460 Series models. The G-Class has been sold under the Puch name in certain markets, and the Peugeot P4 is a variant made under license, with a Peugeot engine and other equipment.

Mercedes-Benz secured military contracts for the vehicle in the late 1970s and offered a civilian version to the public in 1979. Designed to be a durable, reliable, and rugged off-roader, the G-wagen utilizes three fully locking differentials (one of the few vehicles sold in the U.S. to have such, along with the Jeep Wrangler Rubicon, Toyota 80-series Land Cruiser, Pinzgauer High Mobility All-Terrain Vehicle, and Mercedes-Benz Unimog). Among the engines offered in the G-Class for the 2004 model year is a 5.5-litre V8.

Marking its 25th anniversary, the 2005 Mercedes-Benz G55 AMG was relaunched as the G55 Kompressor or G55K and received a boost in power, thanks to a 5.5-liter, supercharged V8 developing 469hp (350kW) and 516lb·ft (700N·m). of torque.

The G-Wagen was first offered for sale in 1979 and redesigned in 1990/ 1991. A new version was expected for 2007, but the new GL-Class will not replace the G-Wagen and it will continue to be hand-built in Graz, Austria at an annual production rate of 4,000 to 6,000 units.

W460

The original W460 G-Wagen went on sale for civilian buyers in the model year 1979. It was offered with two wheelbases, a short wheel base (SWB) of 2400 mm and a long one (LWB) of 2850 mm. One could choose between three body styles: A 2-door SWB convertible, a 2-door SWB wagon and a LWB 4-door wagon. The two wagons were also available as windowless 2-door Van (or 'Kastenwagen' in German). During the G-wagens impressive life span many a different body style was made for army and public-service clients, like the Popemobile, the pickup or the chassis/ cab with a wheel base of 2850, 3120 or 3400 mm, the chassis/ cab being the base vehicle for army-ambulances or communication vehicles. Please note that, because of the sheer variety of military versions, this article is mainly about the somewhat more standardized civilian G-Wagen.

The W460 was popular with military and off-road enthusiasts, with more than 50,000 built in the first decade. The vehicle was not offered in the United States officially, but by means of "casual importation" grey-market in the mid-1980s, importers were successful in selling some G-Wagens (mostly W463s) that had been modified to meet US DOT specifications for around $135,000.

W461

The production of the W460 ended August 1991. It was replaced by the all but identical W461. Initially, engine choices were limited to the four cylinder 230GE petrol- and five cylinder 290GD diesel engine. The W460 'cabrio' version was skipped. From 1997 the W461 sported a slightly updated interior with better seats, changed door panels and an updated dash. From this time, the W461 was only available as 290GD Turbo Diesel with 4-speed automatic transmission. The petrol engine was dropped. Disc brakes all around became standard and the bell-housing of the front axle was changed to accommodate larger reduction-gears. The exterior and other mechanics changed little, not even the model badge which kept indicating 290GD.

The main technical difference between the W460/ 461 and W463 model, apart from the choice of engines, gearboxes and heavy-duty suspension, is the layout of the drive train. Whilst the W463 offers full-time 4WD, the W460/ 461 is basically rear wheel drive with manually selectable 4WD. This means that these models do not have a centre differential, thus no centre diff-lock. Only front and rear locking differentials are needed to obtain a fully locked drive train. The front lockers were not fitted as standard, but as a factory-fitted option. The difflocks are manually operated using hydraulic levers next to the transfer case selector handle. Other differences between W460/ 461 and W463 models are mainly cosmetic. From the front, the W460/ 461 can be easily recognized by its grille and headlight covers which differ slightly from the W463 and are always black (on a factory standard car), even if the rest of the bodywork is not. If fitted, wheel arch extenders are made of unfinished plastic, thus also black. Furthermore are the rear view mirrors mounted on the front doors instead of being mounted at the base of the A-pillar. The model badge is integrated in the base of the mirror. Finally, from behind, the biggest differences are the fuel cap, which is not covered on the W460/ 461, and the arrangement of the taillights and bumpers. The last and most notable difference can be found inside the car. Where the W463 is very luxurious (wood/ leather/ electrics etc.), the simpler model is quite basic, with a dash and trim that closely resembles the original vehicles from the late 70's. Apart from the choice of rugged materials, some luxuries like automatic transmission (standard on the 290GD TD), power steering (standard on W461), ABS, drivers airbag, central locking, engine pre-heater, air conditioning (rare), heated seats and electric windows were available for the W460/ 461. Since 2001 the W461 is no longer available for civilian customers. With its demise the very last Mercedes-Benz sporting the old naming-scheme vanished. The 290GD TD was never rebadged as G290 TD.

W463

Main article: Mercedes-Benz W463

The chassis was revised for 1990 as the W463 with anti-lock brakes, full-time 4WD and a full trio of electronically-locking differentials. The interior was totally upgraded, finished with wooden accents and optional leather upholstery.

The range was refreshed again in 1997, including the introduction of a power-topped convertible and two new engines, the 2.9L Turbo Diesel and the V6-powered (M112 motor) G320 - previous years' G320s were outfitted with the M104 I6. The V8 G-wagen returned with a new engine in 1998 as the G500, with official sales beginning in the United States in 2002 at $75,000. The 349hp (260kW) G55 AMG cemented the vehicle in the American market with many snapped up by celebrities. The most powerful V8, the 476hp (355kW) (later 500hp (370kW)) G55 AMG Kompressor, introduced in 2004 as model year 2005, is able to hit 60mph (100km/ h) in just 5.4 seconds. In 2005 M-B was considering that it would be the LAST YEAR they would import the Geländewagen into the USA market. They even launched a "Grand Edition" (something they like to do to sell off the last of a particular model). One reason it was supposedly continued in the US market was because of a order placed for some 160+ diesel units for the US Marine Corp (H1 HumVees don't fit well in the V-22 Opsrey). t2005 was the FIRST YEAR the G55 AMG model boasted 469 HORSEPOWER, a 120 HP increase over the '03 and '04 AMG models.

The new G500 has a 382 horsepower 5.0 liter V8 engine, while the G55 AMG has a 476 horsepower 5.5 liter V8 engine. The G500 gets from 0 to 60mph in 6.0 seconds, while the G55 AMG takes a mere 4.8 seconds.

The W463 client had a larger choice of engines, the preliminary apex being the V8-powered 500GE in 1993. This catered more of a luxury than off-road crowd with only center and rear differential locks and an even more luxurious cabin. The 500GE was produced in limited numbers for just two years. All W463 G-Wagens began using Mercedes-Benz's new letter-first naming scheme in 1994.

Various automobile tuners such as AMG, BRABUS, LORINSER, Carlsson (car company) and RENNtech have modified the engine and exterior with a 3.6 liter engine.

It was rumored that, with military contracts for the G-Class completed, production of the old G-wagen in Graz, Austria would cease as of 2006. However, reports state that production of the current G-wagen will continue for the foreseeable future, alongside its once-intended replacement, the GL-Class (X164). An outcry among enthusiasts who admired the G-Class for its tremendous off-road potential showed that a market still existed for such a vehicle. Mercedes-Benz elected to continue G-Class production for the hardcore off-road market, while the larger 3-row GL-Class would be marketed as a competitor for the likes of the Cadillac Escalade and Lincoln Navigator.

As of July 2006, Mercedes-Benz announced a late-availability 2006 model year G-Class on its website. The company also showed a facelifted 2007 model at the Paris Auto Show in September 2006 and increased the power of the G 55 AMG version from 476 to 500hp (370kW). Currently the 2009 G 500 and G 55 AMG is offered for sale at the 30-year Anniversary of the G Class. Both models with cosmetic upgrades most noticeable with the new grill, rims, etc. Mercedes-Benz has announced that the G-Class will continue to be manufactured through 2012 due to continued good worldwide demand including for military purposes.

Argentina The Argentine Army uses the MB-230G (short and long chassis) since the 1980s, in different roles; some 900 remain in service.

Canada A total of 1,159 vehicles have been ordered by the Canadian Army beginning in late 2003. An armoured kit can be fitted (or removed) in 8 hours by three soldiers. Their light armour has been criticised for leading to loss of life in Afghanistan, however it is considerably better than the Iltis predecessor. Delivery of these vehicles to Reserve units has also begun; they will be employed in armoured reconnaissance units. It is in the final stages of fully replacing the Iltis in most units as the armoured reconnaissance vehicle in use LFCA. Other units will replace the Iltis with a militarized Chevrolet Silverado known as the MILCOTS (or colloquially as the "Milverado".) :For the most exposed missions in Afghanistan 75 RG-31 Nyala built by BAE Land Systems OMC, South Africa, will be used.
