Vehicle Performance Comparison
Acceleration and Braking
A good way to evaluate horsepower is to draw a segment on a straight part of the track, in
between shift points. Then look at the Max Acceleration values in that segment. You can see the
difference in power between vehicles visually by looking at the slope of the lines in the Velocity vs
Distance Graph since the rate of gain of velocity is acceleration.
Similarly, by looking at the negative slope one can determine the strength of the brakes (and of
course the adhesion of the tires).

To evaluate the outer limits of chassis adhesion, the proven method is the skidpad. Traqmate is
an ideal tool for collecting and analyzing skidpad data.
