100-meter acceleration is a test of the car's engine power. An average car takes about 8 seconds to cover 100 meters, while a supercar typically takes only 3 seconds. Additional information: Maximum speed: The maximum speed refers to the highest driving speed a car can achieve on a level and well-paved road (concrete or asphalt). It is the speed at which the driving resistance and driving force are balanced under windless conditions on a flat road, and it is one of the three evaluation indicators of a car's dynamic performance. Influencing factors: There are many factors that affect a car's maximum speed, such as the engine's power, maximum torque, rotational speed at maximum torque, transmission ratio, and driving resistance. The maximum speed is measured on a flat and windless road with zero acceleration, so gradient resistance and acceleration are zero. Therefore, the main resistance factors affecting the maximum speed are air resistance and rolling resistance.

I tested the 0-100 km/h acceleration in my regular family car and found it took just over 7 seconds to complete the first 100 meters. This process can be divided into three stages: about 0.3 seconds are lost during initial gear engagement, followed by slight power delivery lag; the mid-range acceleration feels most vigorous, with speed surging rapidly from 40 km/h to 80 km/h; the final stage shows noticeable power tapering. There are significant variations between models - CVT-equipped cars feel sluggish at launch, while RWD cars lose more time due to wheelspin. On wet roads during rainy days, the entire acceleration process becomes about 1 second slower.

I once experienced straight-line acceleration in a friend's top-tier supercar. The onboard timer showed a 0-100 km/h time of 2.3 seconds, which roughly translates to about 2.8 seconds for a 100-meter sprint. The sensation of acceleration was truly surreal: the moment you floor the throttle, you're instantly pinned to the seat, the scenery ahead distorts at high speed, and your ears are filled with the high-pitched whine of the supercharger. However, achieving such performance requires launch control, track tires, and near-perfect road surface temperatures—conditions that are impossible to replicate on regular streets. For ordinary performance cars, breaking the 4-second barrier is already considered impressive.

Calculating the theoretical fastest time requires considering physical limits. Assuming the vehicle can maintain a maximum acceleration of 2g (approximately 19.6 m/s²) throughout, according to the formula s=½at², the 0-100m acceleration would take about 2.02 seconds. However, in reality, tire traction can only support up to 1.5g, and internal combustion engine vehicles have power response delays. The Tesla Plaid, a pure electric vehicle, has been measured at 2.3 seconds for 0-100 km/h acceleration, corresponding to approximately 2.9 seconds for 0-100m. Additionally, air resistance increases with speed, affecting acceleration efficiency, making the actual time about 15% slower than the theoretical value.

As an enthusiast who frequently races on tracks, I pay more attention to practical acceleration performance. For ordinary four-door sedans like the Accord, it takes about 7 seconds from pressing the throttle to completing a 100-meter sprint. The focus is not on the absolute time, but on the smoothness of the entire acceleration process: whether the gearbox shifts crisply, the noticeable degree of turbo lag, and the stability of tire grip. Modified cars equipped with differential locks can improve the time to just over 5 seconds, but require more advanced driving skills to control torque output.
