    Eddie FourFather Hill's Ariel Atom 3 acceleration and deceleration MPH vs time

    This is at Eagles Canyon Raceway with my 2012 Ariel Atom 3 supercharged 300HP and 1325 pound demonstrator/company car.



    As you can see here, the acceleration and deceleration is almost breathtaking. Chart is in MPH versus time in seconds.

    The start of the chart on the left side is the start/finish line. Less than two minutes for a complete lap.

    Each horizontal dot is one second.

    This is around the 11 turn, 2.5 mile track, with 70 foot elevation change. The longest straight is 2000 foot.

    Huge fun, and I hardly ever have to work on the car!

    Here are the acceleration (green) and braking (red) zones, and in-between shown in black (transitions from acceleration to braking, or shifting)

    How in the world did you start from 115 mph? I must not be reading the chart right or there is missing data, or is this a rolling start?

    Must be a flying lap, he also ends it around the same speed. Just imagine the graph looping.

    The chart represents one lap of a session of eight to twelve laps. When the session starts, we take around two laps to get everything warmed up (especially the tires and brakes) and then one cool-down lap, after the checkered flag, to cool down the brakes, and I usually don't use the brakes at all on the cool-down lap.

    This screenshot of my TraQdash data recorder (this one is from Hallett, Oklahoma, where the AtomFests were held) instead of the Eagles Canyon data shown in the two charts above. Eagles Canyon Raceway at Decatur, Texas, is (fortunately for me) only about an hour and a half from my hometown of Wichita Falls, Texas.



    The inconsistency in the lap times is due to my driving, and not the fault of the car.
