In the automotive industry, engine downsizing is the practice of utilizing smaller combustion engines over larger ones of the same power capacity when manufacturing vehicles. It is the result of car manufacturers attempting to provide more efficient vehicles that emit fewer emissions , [ 1 ] often mandated by legislative standards . [ 2 ]
Lightweighting is a concept in the auto industry about building cars and trucks that are less heavy as a way to achieve better fuel efficiency, battery range, acceleration, braking and handling. [1] [2] In addition, lighter vehicles can tow and haul larger loads because the engine is not carrying unnecessary weight. [3]
In both the interest of fuel economy and weight reduction, the B/C-platform ended the use of "big-block" V8 engines outside of the Cadillac division; after 1980, a 350 cubic-inch V8 was the largest engine fitted in a B-body chassis. In 1985, General Motors underwent a further downsizing of many of its nameplates using the B-platform chassis.

The engines are small in both physical dimensions and power output, relative to larger automobile engines.Power outputs are typically less than 11 kW (15 hp). The smallest of all are used in handheld garden machinery, such as string trimmers and chainsaws, which have a displacement as small as 24 cc (1.5 cu in). [2]

GM says this engine weighs 216 pounds (98 kg), ready for installation. [2] The engines debuted in the 2014 Opel Adam [3] and are produced in Szentgotthárd, Hungary, [4] and GM's Flint Engine plant. [5] By 2018, the new engine family had spread to other brands and markets and had replaced three separate engine families (S-TEC, Family 0, and ...
Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while ...
