G vs. Distance Analysis
The G vs. Distance graph shows the G forces on the vehicle plotted against the distance traveled.
This is very useful for viewing the overall performance envelope that a driver is using in the car.
On the graph below you can see that the black car’s graph lines are consistently outside the
green cars, indicating that the car is carrying more speed through the turns and consequently
generating more lateral cornering force.
Another useful element of this graph is the ability to determine when a driver hits the brakes and
throttle. You can clearly compare when each driver hits the brakes, gets off the brakes, and gets
back on the gas.
This graph is also good for comparing braking curves for the drivers. Optimally you want to see a
good crisp initial brake pressure, even pressure during braking, and then a clean transition off the
brakes and into the turn. The solid line and dotted line should form a perfect X as in the diagram.
Also look for nice smooth lines. Spikes in the solid line indicates a throttle lift or brake tap, which
is usually not desirable.
