Mercedes-Benz G-Class

Mercedes-Benz G-Class

The Mercedes-Benz G-Class or G-Wagen (as it was called from 1979 to 1994), short for Geländewagen (or cross-country vehicle), is a four-wheel drive vehicle / sport utility vehicle (SUV) produced by Steyr-Puch (now Magna Steyr) in Austria for German automaker Mercedes-Benz. The G-wagen is characterized by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few vehicles to have such a feature. Despite the introduction of an intended replacement, the unibody crosover SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is the longest produced Mercedes-Benz in Daimler's history, with a span of 32 years.
The G-class was developed as a military vehicle from a suggestion by the Shah of Iran (at the time a great shareholder) to Mercedes and offered as a civilian version in 1979. The G-class replaced the cheaper Volkswagen Iltis in 1990. In this role it is sometimes referred to as the "Wolf" and LAPV Enok. 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 different parts.




History

Development started in 1972, focusing on off road abilities and maximum safety and comfort; with a cooperative agreement between Daimler-Benz and Steyr-Daimler-Puch in Graz, Austria. Mercedes-Benz engineers in Stuttgart were in charge of design and testing, while the team in Graz developed the production plans. The first wooden model was presented to Daimler-Benz management in 1973, with the first drivable prototype beginning various testing including German coalfields, the Sahara Desert, and the Arctic Circle in 1974. Construction commenced on a new production facility in Graz, where the new cross-country vehicle would be assembled nearly entirely by hand in 1975, with production of the "G Model" beginning in Graz in 1979. In 1980, the Vatican took delivery of a specially made G-Wagen outfitted with a clear thermoplastic top which served as the Popemobile. The “Papa G” later took up permanent residence at the Mercedes-Benz Museum in Stuttgart, Germany.
The first major refinements were introduced in 1981, including an automatic transmission, air conditioning, an auxiliary fuel tank, protective headlamp grilles and a cable winch. Fuel injection became available in 1982, when the 230 GE was introduced in Turin,along with more comfortable and supportive front seats, auxiliary heating, wider tires and fender flares. For 1985, differential locks, central door locking and a tachometer become standard and in 1986 50,000th G Models had been produced.
The G-Wagen was facelifted in 1990. In 1989, for the 10th anniversary of the G Model, a new model variant with permanent 4-wheel drive, a wood-trimmed interior and optional Anti-lock Braking System (ABS) debuted at the Frankfurt International Motor Show. Production began the following April. For 1992, a new sub-series for professional users began production. The civilian model began to offer cruise control, a stainless-steel spare-tire cover, running boards and Burl Walnut wood interior trim. The same year, the 100,000th G Model was built in Graz. In 1994, the model line was officially renamed the G-Class. Ventilated front disc brakes and a driver’s air bag became standard. In 1996 the automatic transmission became an electronically controlled 5-speed unit. Headlamp washers, cruise control and a front passenger’s air bag were added. In 1998, the range-topping G 500 with a 296 hp V 8 was introduced for series production.
For 1999 a limited run of V 8 powered "G 500 Classic" special editions marked the model's 20th anniversary. A multifunction steering wheel was added to all models. Later in the year, the new G 55 AMG debuts as the most powerful G-Class yet, with 354 hp. The U.S. market launch of the G-Class took place in 2001. New alloy wheels, a chrome grille and body-color bumpers plus a more luxurious cabin were introduced. New dynamic control systems included the Electronic Stability Program (ESP), Brake Assist and the 4 wheel Electronic Traction System (4 ETS). The G 55 AMG was upgraded in 2004 with a supercharged V 8 engine developing 476 hp. In Siberia in 2006, a documentary filmmaker was the first foreigner to reach the world’s coldest region with a passenger vehicle in winter, driving a stock G 500 nearly 19,000 km without a single breakdown, in temperatures as frigid as -63˚F/-53°C.
A new version was expected for 2007, but the new GL-Class did not replace the G-Wagen, and it will continue to be hand-built in Graz, Austria at an annual production of 4,000 to 6,000 units. In February 2009, Magna Steyr, an operating unit of Magna International, announced that it signed an agreement with Daimler AG to extend the production of the Mercedes-Benz G-Class at Magna Steyr in Graz, Austria until 2015. Besides the production, the further development of the G-Class by Daimler's subsidiary Mercedes-Benz Consult Graz since 1992.
For 2007 the output of the G 55 AMG was raised to an even 500 hp. Bi Xenon headlamps, corner-illuminating front foglamps and new scratch-resistant nano-particle paint finishes were offered for the first time. In 2008 more-refined instrumentation and controls were included in the G-Class cabin, along with the COMAND system with hard-drive-based navigation, a rear view camera, voice control, Bluetooth and a Tire Pressure Monitoring System. The Vatican receives a new white “Popemobile” based on a G 500. 2009 marked the 30th anniversary of the vehicle, with over 200,000 units having been manufactured in Graz since 1979.

G-Wagen 460 and 461

The original 460-series Geländewagen went on sale for civilian buyers in 1979, after having debuted in February of that year. It was offered with two wheelbases, a short wheelbase (SWB) of 2,400 mm and a long one (LWB) of 2,850 mm. One could choose between three body styles: A two-door short wheelbase convertible, a two-door SWB wagon and a long wheelbase four-door wagon. The two wagon versions were also available as windowless two-door Vans (or Kastenwagen in German). While always assembled in Graz, the car was sold as the Puch G only in the Austrian, Swiss, and Eastern European markets.
During the G-wagen's 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 wheelbase of 2,850, 3,120 or 3,400 mm, the chassis/cab being the base vehicle for army-ambulances or communication vehicles. Because of the sheer variety of military versions, this article focuses on the more standardized civilian G-Wagen.
The 460 was popular with military and off-road enthusiasts, with more than 50,000 built in the first decade. Mercedes-Benz initially did not sell the model in the United States, but by means of "casual importation" grey-market in the mid-1980s, importers sold a number of G-Wagens which had been modified to meet the specifications by the US DOT,at about $135,000.
 
 
G-Class 463

The chassis was significantly revised for 1990, and resulted in the new 463 G-Class. Equipped with anti-lock brakes, full-time 4WD and a trio of electric locking differentials. The interior was totally upgraded, finished with wooden accents and optional leather upholstery. The 463 features a larger choice of engines, with the V8-powered 500 GE added in 1993. The 500 GE was produced in limited numbers for just two years. All 463 G-Wagens began using Mercedes-Benz's new letter-first naming scheme in 1994.


1997 update

The range was refreshed again in 1997, including the introduction of a power-topped convertible and two new engines, the 2.9 L 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 349 hp (260 kW) G55 AMG cemented the vehicle in the American market, becoming a vehicle of choice for many celebrities.

2005 update

Mercedes-Benz considered that 2005 would be the last year they would export the Geländewagen to the USA market; however, with an order placed by the U.S. Marine Corps for 157 Mercedes-Benz units to replace their archaic Desert Patrol Vehicle with a more modern and militarized Interim Fast Attack Vehicle, the manufacturer continued to offer the vehicle in the US market. To celebrate the supposed end of US market Geländewagens, 500 examples of the "Grand Edition" model were made available. All "Grand Edition" are marked with external Grand Edition badging on the front fenders as well as silver plaque with specific series number "xxx of 500" on the interior of the vehicle. Also new for the 2005 model year was the first G55 AMG model, boasting a 469 hp (350 kW) V8 engine. So equipped, an original G55 AMG is able to achieve 60 mph (97 km/h) in 5.4 seconds.
The new G550 has a 32-valve 382-horsepower 5.5-liter V8 engine, while the current G55 AMG has a 500-horsepower supercharged 5.4-liter V8 engine. The G550 goes from 0 to 60 mph in 7.2 seconds, while it takes the G55 AMG 5.2 seconds.
 
Brabus G V12 Biturbo
Various automobile tuners such as AMG, Brabus, Lorinser, Carlsson, A.R.T., and RENNtech have all modified the engine, interior, and exterior.
It was rumored that, with military contracts for the G-Class completed, production of the old G-wagen in Graz, Austria would cease in 2006. However, reports state that production of the current G-wagen will continue for the foreseable future, alongside its once-intended replacement, the 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.

G 55 AMG Kompressor (2006)

In the mid-year update, the engine was updated to increase power to 500 PS (368 kW; 493 hp) and torque to 700 N·m (516 lb·ft)@2750-4000 rpm via enhanced and retuned engine control unit. Other features include 18-inch AMG light-alloy wheels in titanium grey with 285/55 R 18 wide-base tyres, bi-xenon headlamps, oval foglamps with a cornering light function and ISOFIX child seat attachments in the second seat row, scratch resistant body paint in calcite white, periclase green metallic and teallite blue metallic.
The vehicle went on sale in September 2006, in long Station Wagon body only
 






Mercedes-Benz W114

Mercedes-Benz W114

The Mercedes-Benz W114 and W115 models are a series of coupes and sedans introduced in 1968 by Mercedes-Benz, manufactured through model year 1976, and distinguished in the marketplace by nameplates designating their engines.
W114 models featured six-cylinder engines and were marketed as the 230, 250, and 280, while W115 models featured four-cylinder engines and were marketed as the 200, 220, 230, and 240.
All were styled by Paul Bracq, featuring a three-box design. At the time, Mercedes marketed sedans in two size classes, with the W114/W115, positioned below the Mercedes-Benz S-Class.
Beginning in 1968, Mercedes marketed their model range as New Generation Models,giving their ID plates the designation '/8' (due to their 1968 Launch year). Because they were the only truly new cars of the so-called 'New Generation' and because of the '/8' or 'slash eight' designation, W114 and W115 models ultimately received the German nickname Strich Acht, loosely translated into the English Slash Eight.


History

The W114/W115 models were the first post-war Mercedes-Benz production car to use a newly engineered chassis, not derived from preceding models. The new chassis format of semi-trailing rear arms and ball-joint front end, first displayed in the W114/W115 chassis would be used in all new Mercedes passenger car models until the development of the multi-link rear suspensions of the 1980s. The W108/109 S-Class chassis of the 280S/8, 280SE/8 and 300SEL/8 (and W113 280SL Pagoda) would be the last of the low-pivot swing axle and king pin/double wishbone front ends. The next S-Class -the W116 chassis- having the same engineering of the W114/115.
The W114/W115 models replaced the W110 Fintail models stemming from 1961, and were themselves replaced by the W123 series after 1976.
The Mercedes-Benz W114/W115 was the mid-sized saloon model for Mercedes, positioned below the S-Class. Mercedes also launched its first 5-cylinder diesel engine OM617 in this chassis. It followed heavily in the direction set by the W108/109 S-class, which was launched in 1965 and heralded the new design idiom. The car was designed by French auto designer Paul Bracq who was chief designer at Mercedes-Benz for models from 1957 to 1967, a period that included models such as the Grosser Mercedes-Benz 600. Bracq was also responsible for BMW designs (1970–74) and Peugeot designs (1974–96).


The W114 received a facelift in 1973 - with a lower bonnet-line, lower and broader grill, a lower placement of the headlamps, A-pillar treatment for keeping the side windows clear, ribbed tail lights to minimize occlusion of the tail lights with road dirt, and larger side mirrors. The interior received inertia reel belts and a new padded steering wheel with a four-hole design.
Mercedes introduced a coupe variant in 1969 carrying the nameplate '250C/CE' or '280C/CE' and featuring a longer boot hood and a 2.8 litre six-cylinder engine. It is considered by enthusiasts to be one of the finest classics of the 1960s and 1970s, although this is not reflected in the prices of these cars which is generally less than its more popular contemporaries the Mercedes SL R107/C107 roadster and coupé (1971–1989) which featured the 3.5 or 4.5 litre V8 under the hood, and only a fraction of price commanded by the Pagoda models (1963–1971). While a 'hard-top' unlike the fully convertible SL, the pillarless design allowed all the windows could be lowered completely for open air motoring. Only 67,048 coupés were manufactured from 1969 to 1976 (vs. 1.852,008 saloons). Of these 24,669 were "280C" and "280CE" (top of the range), and 42,379 were the lesser "250C" and "250CE". the Mercedes-Benz W115 in known to be a very durable car in year 2004 a greek taxi driver denoted his 1976 Mercedes-Benz 240 D to the Mercedes-Benz Museum Collection with 4.6 Million kilometers covered which becomes the Mercedes-Benz with the highest recorded mileage known to date.

Innovations
Like its saloon variant this car also boasted advanced technological innovations. 1969 saw the introduction of the Bosch D-jetronic fully electronic fuel injection system into the 250CE. This was the first ever production Mercedes-Benz to use this system.
Other innovations in the W114/W115 models include a center console (a first in a Mercedes sedan), ribbed taillights in 1974. All coupe models used the 6-cylinder engine (and thus were W114s) and were designated with a "C" in the model name.
A Mercedes-Benz 220 D pickup on the W115 chassis was built briefly in Argentina in 1970s.

 
 
North America

The W114/W115 was introduced in North America in 1968, but with fewer engine choices than elsewhere. These models from the start had unique headlights, utilizing a sealed beam lamp instead of the H4 type used in the European models. Bumpers changed frequently and there were at least three different bumpers used over the production run in NA. For 1974 the bumpers grew significantly due to new DOT requirements.
North American 240Ds were offered with a 4-speed manual or 4-speed automatic, whereas all 5-cylinder 300D models were equipped with the 4-speed automatic without a manual option.
