What does 'lack of power' mean?

"Lack of power" mostly refers to the symptoms of insufficient horsepower and slow acceleration in a vehicle. The most direct manifestation of power strength should be the initial acceleration, which is mainly reflected in low-end torque. Models with well-matched displacement and vehicle type, and properly tuned, can have quite good low-end torque output. Vehicles with lack of power are basically those with small displacement or inherently insufficient engine performance. More relevant information is as follows: 1. Difficulty in operating vehicles with lack of power: Starting a vehicle with lack of power may consume more fuel, and the speed increase will be slower, making people feel anxious. At the same time, lane changes may also pose certain difficulties. 2. Insufficient state of vehicles with lack of power: One situation with lack of power is a small engine pulling a large vehicle. This situation can cause the engine to operate under overload for a long time, that is, in a non-economical working area, so fuel consumption will naturally increase. This means that small-displacement engines are not necessarily fuel-efficient, and only proper matching can achieve a relatively economical fuel consumption level.
I understand that 'lack of power' is a slang term in the automotive world, meaning the car feels sluggish and lacks pep when accelerating. I've seen this a lot—some older cars with severe carbon buildup from aging engines, or spark plugs that are worn out, or insufficient fuel supply from the fuel system, all of which can make the power output feel weak, like muscles that can't exert strength. On the highway, the throttle response is slow, climbing hills is a struggle, and fuel consumption actually goes up, which really affects the driving experience. Regular engine check-ups, cleaning carbon deposits from the throttle body, and replacing the air filter can help a lot. If the car still feels sluggish, it's best to take it to a professional shop to check the computer data—you might need to replace the turbo or tweak the ECU program to boost performance.
As a long-time car owner, I feel that the lack of power is like stepping on cotton when I press the accelerator in my old SUV, with very slow acceleration. The main issue lies in insufficient engine output, possibly due to a clogged intake system or faulty oxygen sensor, resulting in low combustion efficiency and naturally weak power output. In daily driving, I often get honked at by cars behind me when starting from a red light, and long-distance driving is exhausting. Once, after changing the oil and spark plugs, the situation improved. This reminds everyone to perform maintenance on time and not let small issues turn into big problems, as safety always comes first.
