Very Large Trucks

A further step from this is the side loading forklift that can be described as a specially fabricated vehicle with the same properties as a truck of this type, in addition to the ability to pick up its own load.
• Engine
The oldest truck was built in 1896 by Gottlieb Daimler. Most small trucks such as sport utility vehicles (SUVs) or pickups, and even light medium-duty trucks in North America and Russia will use gasoline engines (petrol engines), but many diesel engined models are now being produced. Most of the heavier trucks use four stroke diesel engine with a turbocharger and aftercooler. Huge off-highway trucks use locomotive-type engines such as a V12 Detroit Diesel two stroke engine. Diesel engines are becoming the engine of choice for trucks ranging from class 3 to 8 GVWs.
North American manufactured highway trucks often use an engine built by a third party, such as CAT, Cummins, or Detroit Diesel, but both Mack and Navistar offer their own engines.
