Is a 1.5L Engine Powerful Enough for Sedans?

[OWyatt]

Generally speaking, a 1.5L engine is definitely sufficient for daily use by ordinary people, such as in compact cars and microvans. However, if you frequently drive on highways for long distances, engage in off-road operations, or traverse mountainous roads, it's better to opt for a slightly larger displacement. Engine Output Power: When discussing a car's power performance, most people refer to the engine's horsepower as a benchmark. However, in reality, the vehicle's weight also constantly affects its power performance. Using the power-to-weight ratio to assess whether a car's power is sufficient is more scientific than simply looking at the power output. Engine Output Torque: In fact, the parameter that truly reflects a car's power is not just the power output but also the torque. Torque represents the engine's force output; the greater the torque, the greater the driving force on the wheels, and the faster the acceleration. Based on the current standards for most vehicles, an A0-class car with 1505N·m, an A-class car with 1755N·m, and a B-class car with 2005N·m are considered sufficient.
