The Mercedes-Benz 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 Mercedes-Benz CLK-Class is a series of mid-size luxury coupés and convertibles produced by German car manufacturer Mercedes-Benz in two generations.
 Although its design and styling was derived from the E-Class, the mechanical underpinnings were based on the smaller C-Class, i.e. respectively based on the W202 and W203 platforms of the C-Class.
 It was positioned below the Mercedes-Benz CL-Class and SL-Class, but above the SLK-Class.
 The CLK name derives from the German "Coupé Leicht Kompakt" (or Kurz), translated Coupé-Light-Short.
 In 2009 Mercedes ceased to use the CLK designation moving the segment designation back to E-Class Coupe/Convertible instead, as it had called this specific line of its vehicles previously before the CLK moniker was introduced in 1997.
Mercedes-Benz EQ is an upcoming family of battery electric vehicles to be manufactured by Mercedes-Benz.
 The first model was previewed at the Paris Motor Show in 2016 with the Generation EQ concept vehicle.
 Mercedes-Benz intends to produce ten EQ models by 2022, three of which will have the Smart brand, representing between 15% and 25% of the company's global sales.
 All of Mercedes-Benz electric vehicle design and production efforts will target the EQ family.
The Mercedes-Benz SLC-Class is a compact luxury roadster manufactured by Daimler-Benz in three generations; R170 launched in 1996, the R171 in 2004 and R172 in 2011.
The Mercedes-Benz E-Class (C207 and A207) are the respective coupé and convertible versions of the fourth generation Mercedes-Benz E-Class automobile.
 Sold from 2009 until 2017 by Mercedes-Benz, the C207 and A207 replaced the previous C209/A209 CLK-Class models.
 Like the CLK-Class predecessor, the C207/A207 E-Class are derived from the C-Class.
 Sedan and station wagon models of the E-Class of the same vintage are built on their own platform and are known as the W212 and S212.
 The coupé and convertible share a more aggressive, swifter look than the sedan and saloon, with a more svelte front and a sleeker bonnet.
The Interim Fast Attack Vehicle (IFAV) is a vehicle deployed and used by the United States Marine Force Recon and Marine Expeditionary Units. Force Recon used to operate a fleet of Desert Patrol Vehicles (formerly known as Fast Attack Vehicles or FAVs for short), popularized by the Navy SEALs as the "black dune buggy."
 However, this vehicle lacked cargo capacity and firepower, so Force Recon moved to a militarized Mercedes-Benz G-Class, also known as a G-wagon, 290 GDT diesel 4×4, a much more traditional "Jeep" type truck.
 The vehicle has only minimal armor, but numerous defensive weapons, including a Mk 19 automatic 40 mm grenade launcher.
 This vehicle is manufactured by Magna Steyr (Austria) for Mercedes-Benz (Germany).
The Mercedes-Benz W140 is a series of flagship vehicles that were manufactured by the German automotive company Mercedes-Benz.
 On November 16, 1990, Mercedes-Benz unveiled the W140 S-Class via press release, later appearing in several February and March editions of magazines.
 The W140 made its public debut at the Geneva Motor Show in March 1991, with the first examples rolling off the production line in April 1991 and North American examples on August 6, 1991.
 Short (SE) and long (SEL) wheelbase sedans were offered initially, as well as the coupé (SEC=S-Klasse-Einspritzmotor(Fuel injection engine)-Coupé) body style C140 from October 1992.
 Like all Mercedes-Benz lines, the W140 S-Class was rationalized in late 1993 using the new "letter-first" nomenclature.
 The SE, SEL, and SEC cars were renamed the S-Class, with alphanumerical designations inverted.
 For example, the 500 SE became the S 500, and the 500 SEL became the S 500 L.
 In 1996 the coupé models following a mid-life update were separated into the CL-Class.
 The W140 series S-Class was superseded by the W220 S-Class sedan and C215 CL-Class coupe in 1999 after an eight-year production run.
Mercedes-AMG GmbH, commonly known as AMG, is the high performance division of Mercedes-Benz.
 AMG independently hires engineers, manufactures and customizes Mercedes-Benz AMG vehicles.
 Mercedes-AMG is headquartered in Affalterbach, Baden-Württemberg, Germany.
 AMG was originally an independent engineering firm specializing in performance improvements for Mercedes-Benz vehicles; Daimler-Benz AG took a controlling interest in 1999, then became sole owner of AMG in 2005.
 Mercedes-AMG GmbH is now a wholly owned subsidiary of Daimler AG.
The Mercedes-Benz GLS-Class is a Fullsize luxury crossover SUV produced by the German carmaker Mercedes-Benz since 2006.
 It is a three-row, seven-passenger vehicle positioned above the GLE-Class in the lineup and is the flagship of the Mercedes-Benz SUV line.
 The GLS shares the same unibody architecture with the GLE-Class.
 The vast majority of GLS-Class vehicles are assembled at Mercedes-Benz US International, Inc, in Tuscaloosa County, Alabama except for a small number of early production 2007 model vehicles which were manufactured in Germany.
 The first generation (X164) was manufactured between 2006 and 2012 and was replaced in 2012 by the new generation GL-Class (X166).
Mercedes-Benz G63 AMG 6×6 is a SUT manufactured by Mercedes-Benz.
 A SUT derivative of the six wheel drive Mercedes Geländewagen developed for the Australian Army from 2007, at the time it was the company's largest and second most expensive street-legal offroad vehicle, manufactured by Magna Steyr in Graz, Austria.
 It combined the engine from the G63, a twin-turbo V-8, with a 6x6 portal axles, with pick-up version of the G-Class body, and a luxury interior.
 It was produced from 2013 to 2015, with production exceeding 100 vehicles.
