0-60 Calculator

Zero to sixty is an acceleration question, and this answers it three ways. Give it a time and it returns the average acceleration in g and in metres per second squared along with the road the run takes; give it a distance and a final speed and it returns the time instead. The third form estimates the run from weight and horsepower, treating the launch as grip limited and the rest as power limited, with your drivetrain loss, tyre grip and gear-change time as inputs. The first two are exact kinematics for constant acceleration, while the third is a model that leaves out drag and wheelspin, so read it as a ballpark rather than a timing slip.

You have the 0 to 60 time. This says what that is in g, and how much road it takes.

Speed Unit

You know how far it took to reach a speed. This works back to the time and the acceleration.

A grip-limited launch followed by a power-limited pull. Every loss in it is a box you can change.

Roughly 15 percent for a manual rear drive car and 20 to 25 for an automatic or all wheel drive. Enter 0 if your figure is already a wheel horsepower.
How hard the tyres will pull off the line. Around 0.9 for a street tyre on dry pavement, 0.6 or less in the wet, and over 1.0 only on something sticky. Front drive cars rarely reach 0.5 because the weight moves off the driven wheels.
No engine sits at its peak the whole run. Around 85 percent is a fair average for a broad modern engine, less for a peaky one that has to be revved out.
Two shifts at about 0.3 s each for a manual. A good dual clutch loses closer to 0.1 s a shift, and a car that reaches the speed in one gear loses none.
60 mph is the benchmark quoted in the United States; 100 km/h is the one quoted nearly everywhere else.
