Mercedes-Benz LF – fire-engine chassis of the 408 to 1313 series: the numbering scheme of gross weight and horsepower, petrol and diesel engines, 4 to 6 cylinders, 2.2 to 5.7 litres
This page gathers Mercedes-Benz chassis of the 408 to 1313 series that served as the basis for fire engines of the German fire brigades. The type designation follows the classic factory scheme of the 1970s and 1980s: the first one or two digits give the gross vehicle weight in tonnes, the following two the engine output in hp divided by ten, B denotes a petrol and D a diesel engine – the LF 608 D a six-tonne chassis with about 80 hp diesel, the LF 1113 B an eleven-tonne chassis with about 130 hp petrol. The chassis were built at the Wörth am Rhein plant, Mercedes-Benz's main truck works since 1965.

Bodybuilders such as Metz, Magirus, Ziegler and Schlingmann fitted these chassis with fire engine bodies that for decades formed the backbone of Germany's volunteer and professional fire brigades, with crew cab, pump and water tank on the chassis.
On used examples, rust on frame and cab, the condition of pump and bodywork, mileage and the service book count, and on the diesel engines the injection pump and clutch; parts for chassis and engine run through the classic Mercedes-Benz truck network, and for the fire-service bodywork through the respective bodybuilders.
