Lots of factors involved. Even if it's really windy it can diminish performance. To get the exact performance of the vehicle it is usually done in specific conditions and location. Even the Bugatti high speed runs requires specific air pressures and wind speeds. Lots of things go into it. Just cause a car is stated to do 2.9 0-60mph doesn't mean it will do it every time. It's the conditions and driver and the car. Everything has to be perfect to get the accurate numbers.
