Does a Small-Displacement Engine Consume More Fuel on Highways?

[LeLily]

Small-displacement engines consume more fuel on highways. Reasons why small-displacement engines consume more fuel on highways: Small-displacement engines produce lower torque output. To maintain vehicle performance, they must operate at relatively high RPMs for extended periods, leading to increased fuel consumption. Introduction to small-displacement vehicles: By conventional definition, small-displacement vehicles typically refer to "micro cars" with engine displacements around 1.0 liters, achieving fuel consumption below 5 liters per 100 kilometers. Compared to vehicles with 1.4-liter engines, they save approximately 4 liters per 100 kilometers. For a typical family car driving 2,000 kilometers monthly, small-displacement vehicles can save nearly 1,000 liters of fuel annually. These vehicles are economical, energy-efficient, and environmentally friendly. With increasing energy constraints and potential gasoline price hikes, the energy-saving benefits of small-displacement cars are undeniable facts.
