The Mercedes G-Class, sometimes called G-Wagen (short for Geländewagen, "cross country vehicle"), is a mid-size four-wheel drive luxury SUV manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. In certain markets, it has been sold under the Puch name as Puch G. 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 SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest produced Mercedes-Benz in Daimler's history, with a span of 35 years. Only the Unimog surpasses it.The G-class was developed as a military vehicle from a suggestion by the Shah of Iran (at the time a significant Mercedes shareholder) to Mercedes and offered as a civilian version in 1979. In this role it is sometimes referred to as the "Wolf" and LAPV Enok. The Peugeot P4 is a variant made under license, with a Peugeot engine and different parts. It was not available from Mercedes-Benz in the United States until 2002, although this was preceded by a grey-market where even basic models commanded six-figure prices in the 1990s. It was launched in 2002 as the Mercedes-Benz G500 with a V-8 gas engine and achieved 3114 sales that year.This eventually tapered down to some sub-1000 sales years, however, in the 2010s sales began to increase again surpassing 3000 in 2014 and in 2015 it sold more than in its launch year, with 3616 sold that year. So called "off-road" vehicles have been heavily mocked for their wide-spread on-road only use in the USA (and realated 4x4 SUV's like the G-Class), however it is indeed deteriorted on-road conditions that can be a matter of life-and-death transportation need, or at least getting to work for many drivers due to inclement weather, such as snow or flooded roads.
