Is a 1.5L Engine Powerful Enough for Sedans?

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.
The 1.5L engine is perfectly sufficient for daily driving and is ideal for urban commuting. When starting from traffic lights, as long as you keep up with the throttle, you won't fall behind. In summer, with the air conditioning on and carrying three people uphill, it might feel a bit sluggish, but if you're willing to step on the throttle, the power kicks in once the RPM reaches 3000. The key point is that this displacement is the most fuel-efficient in its class, with a solid 6 liters per 100 kilometers, making the later car maintenance pressure smaller. For new drivers, this displacement is actually safer, as the power isn't too aggressive, making it easier to control.
