Many other materials are used to meet lightweighting goals. [12] Cost of lightweighting, and increasingly sustainability of materials, is becoming an issue in solution selection - with the viable cost increase of a part per kilogram saved being between $5 and $15, [13] depending on the price point and performance needs of the vehicle.
The moving parts of the supercharger is a disc-shaped displacer with identical spirals (or scrolls) projecting from each side, and manufactured from light alloy to reduce inertia. A pair of fixed scrolls supported by the end walls of the compressor chamber are interleaved with the moving scrolls.
Composite gear housing refers to the use of composite materials to enclose the components of motor transmissions. Fiber reinforced composite materials are used primarily for weight reduction. Carbon fiber reinforced plastic material is commonly used in the aerospace and automotive industries.
Hydroforming is a means of shaping ductile metals such as aluminium, brass, low alloy steel, and stainless steel into lightweight, structurally stiff and strong pieces. One of the largest applications of cost-effective hydroforming is the automotive industry, which makes use of the complex shapes made possible by hydroforming to produce ...
In addition, because bicycles are very lightweight (usually between 7–15 kg) this means they consume very low amounts of materials and energy to manufacture. In comparison to an automobile weighing 1500 kg or more, a bicycle typically requires 100–200 times less energy to produce than an automobile.
Automobile handling and vehicle handling are descriptions of the way a wheeled vehicle responds and reacts to the inputs of a driver, as well as how it moves along a track or road. It is commonly judged by how a vehicle performs particularly during cornering , acceleration, and braking as well as on the vehicle's directional stability when ...
Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance.
As far back as 1971, the Citroën SM offered optional lightweight carbon fiber wheels. [ 32 ] [ 33 ] Use of the material has been more readily adopted by low-volume manufacturers who used it primarily for creating body-panels for some of their high-end cars due to its increased strength and decreased weight compared with the glass-reinforced ...
