Quizplus · Accepted Answer

The energy crises of the 1970s led to a greater emphasis on fuel efficiency and conservation, as countries sought to reduce their dependence on foreign oil and cope with limited supplies. As a result, many vehicle manufacturers developed more efficient cars and trucks, with technologies such as smaller engines, aerodynamic designs, and improved fuel injection systems. This trend towards fuel efficiency has continued over the decades since the energy crises, with new regulations and incentives encouraging further innovation in this area.
