How Much Horsepower is Enough for a Car?

[DelJulianna]

Here is an introduction about how much horsepower is enough for a car: 1. Judging by vehicle weight: For small cars weighing around 1000-1200kg, a naturally aspirated engine of about 1.5L or a 1.0T turbocharged engine is sufficient. For compact cars weighing 1200-1400kg, a 1.2T or 1.4T turbocharged engine will do. For mid-size and large cars weighing over 1500kg, a naturally aspirated 2.4L or a 2.0T turbocharged engine is needed. 2. Assessing car power: Insufficient power means the car's acceleration capability cannot reach its maximum speed. If a car's acceleration time within the same speed range is shorter than what normal traffic flow requires, then the car has sufficient power and horsepower. For driving on city roads, 100 horsepower is adequate. To evaluate a car's power, pay attention to two parameters: one is the power value, and the other is the torque value.
