ANDY'S TOP TEN AUTOX DRIVING TIPS
[Just got back from a weekend of teaching
Evolution schools and thought I'd share some stuff that I
must have said a thousand times. Sure beats talking about
rules!]
1) Position first, then speed. Positioning the car
perfectly is more important than trying to attain the
highest potential speed. For example,you will drop more
time by correctly positioning the car nearer to slalom
cones than you will by adding 1 or 2 MPH in speed. Same
with sweepers (tight line). Same with 90-degree turns
(use all of the track). Also, position is a prerequisite
for speed. If you are not in the correct place, you will
not be able go faster. Or at least not for very long!
2) Turn earlier...and less. To go faster, the arc you are
running must be bigger. A bigger arc requires less
steering. To make a bigger arc that is centered in the
same place, the arc must start sooner (turn earlier).
3) Brake earlier...and less. Waiting until the last
possible second approaching a turn and then dropping
anchor at precisely the correct place so that the desired
entry speed is reached exactly as you come to the turn-in
point is quite difficult to execute consistently.
Especially whenyou consider that you get no practice runs
on the course, and the surface changes on every run, and
you aren't likely to be in exactly the same position with
the same approach speed on every run, etc. Better to
start braking a little earlier to give some margin of
error. And by braking less you can either add or subtract
braking effort as you close in on the turn-in point. This
will make you consistent and smooth.
4) Lift early instead of braking later. Continuing with
the philosophy of #3, when you need to reduce speed only
a moderate amount, try an early lift of the throttle
instead of a later push of the brake. This is less
upsetting to the car, is easier to do and thus more
consistent, and allows for more precise placement
entering the maneuver (remember #1 above).
5) Easier to add speed in a turn than to get rid of it.
If you are under the limit, a slight push of the right
foot will get you more speed with no additional side
effects. On the other hand, if you are too fast and the
tires have begun slipping, you can only reduce throttle
and wait until the tires turn enough of that excess
energy into smoke and heat. Don't use your tires as
brakes!
6) Use your right foot to modulate car position in
constant radius turns, not the steering wheel. In a
steady state turn, once you have established the correct
steering input to maintain that arc, lifting the throttle
slightly will let the car tuck in closer to the inside
cones. Conversely, slightly increasing the throttle will
push the car out a bit farther to avoid inside cones. It
is much easier to make small corrections in position with
slight variations in the tires' slip angle (that's what
you are doing with the throttle) than with the steering
wheel.
7) Unwind the wheel, then add power. If the car is using
all of the tire's tractive capacity to corner, there is
none left for additional acceleration. At corner exit, as
you unwind the wheel, you make some available. If you do
not unwind the wheel, the tire will start to slide and
the car will push out (see #6 above).
8) Attack the back. For slaloms (also applicable to most
offsets), getting close to the cones is critical for
quick times (see #1). To get close, we must move the car
less, which means bigger arcs. Bigger arcs come from less
steering and require earlier turning (see #2). Now for
the fun part... When you go by a slalom cone and start
turning the steering wheel back the other way, when does
the car start to actually change direction? Answer: When
the wheel crosses the center point (Not when you first
start turning back!) How long does that take? If you are
smooth, it takes .25 - .5 seconds. Now, how long is a
typical person's reaction time? Answer: about .5 seconds.
Finally, how long does it take to go between slalom
cones? Answer: Typically on the order of 1 second. Given
all of that, your brain must make the decision to begin
turning the steering wheel back the other way just
*before* you go by the previous cone!!
Since this is a mental issue, a good visualization
technique to get used to this is to think about trying to
run over the back side of each slalom cone with the
inside rear tire of the car. To hit it with the rear tire
(and not the front), the car must be arcing well before
the cone and the arc must be shallow. Attack the back!
9) Hands follow the eyes, car follows the hands. 'Nuf
said.
10) Scan ahead, don't stare. Keep the eyes moving.
Looking ahead does not mean staring ahead. Your eyes must
be constantly moving forward and back, and sometimes left
and right. Glance forward, glance back. Your brain can
only operate on the information you give it.
Bonus Tip: Don't forget the stuff in between the marked
maneuvers! Too often we think of a course as series of
discrete maneuvers. There is typically more to be gained
or lost in the areas that are in between. Payspecial
attention the places where there are no cones.
