Measuring the 0 to 60 mph speed of vehicles is usually done in a closed setting such as a race car track or closed lot used for professional drivers. The closed course is set up for test-drives in order to reduce any variables, such as wind, weather, and traction. Each variable can have a dramatic impact on the friction of the track and the drag placed on the vehicle, which will influence the overall 0 to 60 time that is recorded.Wikipedia (https://en.wikipedia.org/wiki/0_to_60_mph)
A great many variables and conditions can affect a car’s capacity to accelerate. Beyond the obvious engine power and vehicle weight, important factors include:Omnicalculator (https://www.omnicalculator.com/everyday-life/0-60#what-factors-impact-the-0-60-performance)
– Tire size and type;
– Road quality and wetness;
– Car chassis and suspension;
– Electronic aids and launch control;
– Gearbox and transmission;
– Car aerodynamics;
– Atmospheric conditions;
– Car center of gravity; and
– Driver skills.
We can see there are lots of factors could affect the 0-100km/h(0-60mph), weather like temperature, humidity, atmosphere, wind and etc.. some are not listed above, for example tire pressure, rims weight, and etc..
After you setup your car, the next step would be practice, after installing our tune with the torque and power increased, its harder for driver to control it well. Slipping tires is something you should avoid, you don’t need to worry about it on the professional drag strip, but on public road the tires can’t grip the road will affecting the final time. Making it fast is not solely depends on a strong engine but other parts are also important, its a whole thing they are correlated to each other.
While we do the test on public road, actually there is one factor could significantly affect the result, slope of the test road, we all know driving on a downhill road the gravity would help the acceleration, and driving on uphill will slow down. However sometimes its hard to tell by eyes, so some test tools have the feature can shows the charts of slope, like Dragy and P-gear, they are all GPS based performance meter. With the datalog and video the tools provided, you can find out what you could do better and practice.
Hope this article can help you have better understanding about it.
