1973 oil crisisIn October 1973, the members of the Organization of Arab Petroleum Exporting Countries (OAPEC), led by King Faisal of Saudi Arabia, proclaimed an oil embargo targeted at nations that had supported Israel during the Yom Kippur War. The initial nations targeted were Canada, Japan, the Netherlands, the United Kingdom and the United States, though the embargo also later extended to Portugal, Rhodesia and South Africa. By the end of the embargo in March 1974, the price of oil had risen nearly 300%, from US to nearly globally; US prices were significantly higher.
Torsion bar suspensionA torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance.
Volkswagen GroupVolkswagen AG (ˈfɔlksˌvaːgŋ̍), known internationally as the Volkswagen Group, is a German multinational automotive manufacturer headquartered in Wolfsburg, Lower Saxony, Germany. The company designs, manufactures, and distributes passenger and commercial vehicles, motorcycles, engines and turbomachinery, as well as offers related services, including financing, leasing, and fleet management.

Renault 4The Renault 4, also known as the 4L (pronounced "Quatrelle" in French), is a small economy car produced by the French automaker Renault between 1961 and 1994. Although the Renault 4 was marketed as a short station wagon, its minimal rear overhang, and single top-hinged rear opening made it the world's first mass-produced hatchback car, as well as the first front-wheel drive family car produced by Renault. The car was launched at a time when several decades of economic stagnation were giving way to growing prosperity and surging car ownership in France.
HumveeThe High Mobility Multipurpose Wheeled Vehicle (HMMWV; colloquial: Humvee) is a family of light, four-wheel drive, military trucks and utility vehicles produced by AM General. It has largely supplanted the roles previously performed by the original jeep, and others such as the Vietnam War-era M151 jeep, the M561 "Gama Goat", their M718A1 and M792 ambulance versions, the Commercial Utility Cargo Vehicle, and other light trucks. Primarily used by the United States military, it is also used by numerous other countries and organizations and even in civilian adaptations.
Shock absorberA shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below).
Automobile handlingAutomobile 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 moving in steady state condition. In the automotive industry, handling and braking are the major components of a vehicle's "active" safety, as well as its ability to perform in auto racing.
Henry FordHenry Ford (July 30, 1863 – April 7, 1947) was an American industrialist and business magnate. He was the founder of Ford Motor Company, and chief developer of the assembly line technique of mass production. Ford created the first automobile that middle-class Americans could afford, and his conversion of the automobile from an expensive luxury into an accessible conveyance profoundly impacted the landscape of the 20th century. Ford was born on a farm in Michigan's Springwells Township, leaving home at age 16 to work in Detroit.
Mercedes-BenzMercedes-Benz (mɛɐ̯ˈtseːdəsˌbɛnts, -dɛs-), commonly referred to as Mercedes and sometimes as Benz, is a German luxury and commercial vehicle automotive brand established in 1926. Mercedes-Benz AG (a Mercedes-Benz Group subsidiary established in 2019) is headquartered in Stuttgart, Baden-Württemberg, Germany. Mercedes-Benz AG produces consumer luxury vehicles and light commercial vehicles badged as Mercedes-Benz.
Car suspensionSuspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires.
