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.
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 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 ]
The average car weight in 2022 was 4,094 pounds, according to a report from the Environmental Protection Agency. However, what is considered a normal weight will depend on the type of vehicle you ...

Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be mutually exclusive; an engine may be de-tuned with respect to output power in exchange for better economy or longer engine ...
Reducing weight has resulted in using aluminum-silicon alloys more frequently for the engine block in small-displacement engines. Engine blocks of comparable design, but using Al-Si alloys, are not lighter than cast iron engine blocks in the same ratio as that for the specific weights of the materials.
For instance, a small car might need only 10–15 horsepower (7.5–11.2 kW) to cruise at 60 mph (97 km/h). It is likely to be geared for 2500 rpm or so at that speed, yet for maximum efficiency the engine should be running at about 1500 rpm (gasoline) or 1200 rpm (diesel) to generate that power as efficiently as possible for that engine ...
