THE
3.107 MILE Autodromo de la Ciudad de Mexico track hosts
the Mexican Grand Prix. It is the highest track in terms of
elevation at about 5,000 feet above sea level. This reduces the
amount of horsepower available to the cars. So even though the
front straight is incredibly long, you will never see 200 mph,
even with a draft. The track has two distinct sections to it.
The fast Peralta leads onto the front straight, which ends in a
very fast decreasing radius turn. Then the hairpin and the esses
are very tight and similar to a go-kart track. The fast section
is where bravery and car control will reward those willing to
push hard into the fast corners. The esses require finesse with
the accelerator and brake pedal to get through quickly.
Combined, these different sections make the track quite fun and
usually produce good races.
CAR SETUP:
Mexico is quite a difficult track for which to set up the car.
You can easily get a car that is relatively quick, but to get
one the is really fast you need to make it work on the fast and
the slow corners. A car that turns in to the corners in the
esses very quickly is key for fast laps. If it doesn't you'll be
losing a lot of time in that section as you will have to wait
longer than other cars to get the power back down at each exit.
However if you have a car that tends toward oversteer it will be
quite difficult to go flying into turn one.
To overcome this start by setting the car up to be neutral. Use
the roll bars and the shocks to find this point. You needs to
have good grip out of slower corners, like the hairpin and all
of the esses. So setting the rear shocks to be a little softer
than the fronts will help here. Overall a medium shock setting
is a good place to start. Because of the fast corners on the
track and the need to have a car that changes direction quickly
in the esses, you should set the roll bars up on the stiff side.
Setting both the front and rear to the same setting should give
you a car that is fairly neutral.
There are several corners, almost all of which are in the esses,
where you want the car to turn in quickly and allow you to get
back on the power soon. Having a car that allows you to get
power oversteer solves this problem. If you can set up the car
so that when it's on the limit in a turn you can cause it to
oversteer slightly by adding power, you'll find that you can get
the car pointed into the turn much faster, without getting off
the power to do so. This shouldn't affect turn one, as you are
not on the power going through that turn. The Peralta is not
affected either, as you want the car to turn in as fast as
possible there too. So tighten the rear anti roll bar a click or
so more than the front and you should achieve this goal.
The next step is gearing. Fifth is simple. You should top out
just before braking into turn one. Fourth should be set to top
out just before you brake into the turn two chicane. Use the
hairpin to set first gear. It should allow you to get good
traction and as much acceleration as possible out of the
hairpin. Second and third are a little more difficult. most of
the esses are taken in second gear. So this gear needs to let
your engine stay in its power band as much as possible. If you
are bogging down the engine or right near redline, it will be
much harder to use the power to turn the car in to the corners.
Once you find a good second gear, third can usually be set
midway between second and fourth.
Brake balance is not that critical as most braking on the track
is done in a straight line. The turn two chicane does use some
trail braking to rotate the car into it, so that's a good place
to set your brake balance. If you keep loosing the car under
braking there, try pushing the balance more towards the front.

LAP TIMES:
Your lap times during the race should be very consistent
regardless of your fuel load. Of course as the race progresses
and you use up fuel, you will go slightly faster, but not by a
huge amount. In the end your fastest laps should be equal or
just a couple of tenths off your qualifying lap times. When
going for the qualifying lap, you need to make sure you get a
clean lap, as well as getting several warm-up laps before hand
to make sure the tyres are up to temperature and that you are in
a groove to get that perfect fast lap.
PICTURES:
All the pictures included in this guide are thumbnails for
larger versions. It is recommended to click on the thumbnail to
view a larger, more detailed version of the picture. They are
all taken from the chase view as I think that gives the best
overall view of where the car is on the track. However, I
suggest that you always use the in-car view for actual driving.
GOALS:
You should aim for a qualifying lap of about 1:47.50 to 1:48.50.
That should put you pretty far up the grid.
During the race you should aim for 1:48.00 to 1:49.50, depending
on fuel loads, for your lap times if you don't encounter
traffic.
The
replay is 1:47.65 for the Ferrari.
You won't lose several seconds just by reading this, that takes
practice and experience. But, hopefully, this will help you get
there faster.
DEFINITIONS:
Arrival time at the corner
- this is the approximate time when you should be arriving at
your braking point for the corner.
Time to negotiate corner
- this is the approximate time it should take for you to get
from the braking point of the corner to the point at the exit
when you are 'done' with the turn.
Exit time of the corner
- this is the approximate time when you should be 'finished' or
pretty much done turning and heading in a straight line at the
exit.
Entrance speed - this is the speed
you should be doing when you reach the braking point.
Speed through the corner
- this is the slowest speed reached during the corner.
Maximum braking
- As hard as you can brake before locking your wheels.
Note -
The different handling characteristics of the cars in GPL means
that exactly how fast you are through a turn, or where you start
braking or accelerating will vary slightly. However, these
points are fairly close in all cars, and, of course, the concept
is the same.
THE
RACE:
Mexico provides for great racing. The starting grid is wide and
has the entire front straight ahead of it. You can definitely
make up some places at the start here, just make sure you don't
go too deep into turn one or you'll be in the armco. Turn one is
a common place for overtaking as the draft down the front
straight is significant. However, don't be foolish and try going
side by side through turn one unless you are positive both you
and the other car can hold their line perfectly. A mistake I see
a lot is that when people are being pushed hard into turn one
they brake later, and thus go wide, or worse, into the armco,
allowing you to just cruise by on the inside. Don't brake too
late for turn one. The turn two chicane, the hairpin and the
Peralta are the other good overtaking opportunities. The esses
are a hard section to overtake in. However if you are behind a
slow car there you'll lose tons of time. Hopefully the slower
car will realize this and let you by because trying to get by
there will probably end badly.
TURN
ONE:
Entrance speed: approximately 187-190
mph [302-306 kph]
Speed through the corner: approximately 60-65
mph [97-105 kph]
Arrival time at the corner: 12.53
seconds
Time to negotiate the corner: 13.10
seconds
Exit time of the corner: 25.63
seconds
Turn one is the fastest corner on the track.
It requires a well balanced car and
a smooth use of the brake and accelerator to get through
cleanly. It's also a great overtaking opportunity. If you do go
for the inside line to overtake, you may want to brake a little
earlier to make sure you don't run wide and into the car you are
trying to pass.
You'll be in top gear at full speed as you approach the turn. It
starts off fairly gently, but then tightens up as it continues.
Because of this there is a tendency to brake as you go through
the turn, which makes the car start to oversteer and slide out
towards the armco. The solution is not to brake earlier, but not
to brake during the turn. Once you start turning just let the
engine slow you down the rest of the way. The group of three
trees on the left side of the track, just before the turn
begins, makes a great braking reference point. Right
after you pass these trees, brake as hard as possible, continue
in a straight line and shift down to fourth gear.
As
the armco appears on the left continue straight on until the
racing groove darkens. This is just a beat after reaching the
armco. Gently lift off the brakes and turn into the corner.
Follow the groove through the turn without touching the brakes
at all. Keeping a little bit of power on as the go through the
turn helps to stabilize the car as well as preventing you from
slowing down too quickly.
The turn appears to straighten out for a moment before
tightening up again for the second half. You'll need to slow
down more for this section. So once you reach this midway point
in the turn, brake lightly and downshift to second gear. Once in
second, get off the brakes and back on the power. Keep
just enough power to balance the car as the corner starts to
tighten up. You may be able to add some more power as you near
the concrete-filled tyres on your right, gaining a couple of
hundreds of a second.
As
you approach the concrete-filled tyres on your right, pull the
car in towards them, using the fourth one as your apex point.
Make sure you don't clip them as you'll probably damage the
alignment of your car if you do. Keep enough power on through
here to maintain a steady speed of about 65 mph. Don't push the
car through, or you'll have a really slow exit from the left
hand part of the turn.
After passing the fourth tyre start to bring to car around to
the left for the exit of the turn, keeping the amount of power
constant. If you pushed too hard through the right hand bend,
you'll have to back off or brake to make the left hand exit. The
track also has a slightly bump as you transition from the right
bend to the left bend, and any abrupt transitions on the power
or brakes may upset the car. Backing off will severely hurt your
speed down the following straight, so aim to maintain the 65 or
so mph into the left hand bend.
As
you go through the left hand bend, aim to apex near the third
tyre from the end. Then start to let the car drift out to the
right for the exit. Gradually increase the power as you pass the
final tyre. You should reach full power before you reach the
right edge of the track. The grass is very slippery, so if you
get a wheel onto it, you may need to back off the power a
little. The car may want to oversteer under acceleration as you
exit, so be prepared for a slight amount of steering correction
as you exit the turn.
TURN
TWO:
Entrance speed: approximately 147-150
mph [237-242 kph]
Speed through the corner: approximately 45
mph [73 kph]
Arrival time at the corner: 32.45
seconds
Time to negotiate the corner: 9.05
seconds
Exit time of the corner: 41.50
seconds
The turn two chicane is a great turn. You need
a good feel for the car to be quick
through here. Also if you got a good exit from the previous turn
you may be able to pass someone into this turn. You'll be pretty
close to redline in fourth gear as you go into this corner. Line
the car up on the right side, straddling the white line. There
is no useful braking reference point here, but if you set fourth
gear up well you should be able to brake just before hitting
redline and be fine. The racing groove can also provide some
idea of when to brake. After it darkens, continue on for a beat
or two, then brake hard and downshift to second gear.
I
find it better to turn in slightly early at this turn. It allows
you to carry a little more speed into the corner. As you turn
in, ease off the brakes by about half. The car will rotate into
the corner fairly easily. If you spin, then try turning later,
or don't ease off the brakes as quickly. You won't need much
steering input, as the trail brake rotation should do most of
the work for you. Aim to hit the apex at the grass just past the
midpoint of the corner. This will set you up well for the right
hand exit.
As you pass the apex you should be able to get back on the power
for a moment before braking and shifting down
to first for the right hander. Right before you start to brake,
straighten the car out and head for the right side of the track.
Continue to brake gently until you reach the apex of the right
hander. Shift back to second, as this will give you better
traction on the exit. You hit the apex at the grass just before
the midpoint of the corner here. As you leave the apex, don't
get back on the power too soon, or you'll risk understeering off
the track, or just spinning out as you are still turning. Let
the car go right out to the left side of the track as you exit.
A bad exit will allow another car the opportunity to pass you
into the hairpin. So get your exit line down before you start
accelerating out of this corner.
THE
HAIRPIN:
Entrance speed: approximately 135
mph [218 kph]
Speed through the corner: approximately 25
mph [40 kph]
Arrival time at the corner: 47.35
seconds
Time to negotiate the corner: 5.95
seconds
Exit time of the corner: 53.30
seconds
The hairpin is a unique corner in that it
is a 180 degree turn which allows you
to see the other cars coming down the straight at you as you
exit. This can be useful if you want to see how close the cars
behind you are, or if you want to see if you are coming up on
lapped traffic. It is also the slowest corner on the track and
requires good traction to enter and exit it.
You should be able to get into fourth gear before braking for
this turn. Line the car up on the left side of the track,
straddling the white line as you approach the corner. There is a
sign on the left hand bank which makes a great brake marker.
Once you reach this point, brake hard and start shifting down to
second gear. This turn is slightly deceptive because it is
banked. You can enter
it much faster than you'd think because the banking allows you
to continue to brake much farther into it than would be the case
if it was flat. If you think you started braking too late, don't
brake harder and lock your wheels, as you'll just hit the armco.
It's better to come in slightly too hot, or sideways, as the
banking will catch you.
Talking about sliding sideways, if you shift into first too soon
that's what could happen. So wait until you are fairly close to
turning in before getting down to first
gear. Your turn in point is after the armco appears on the left
and just before you reach the end of the grass and the tyres on
the right. Continue to
brake, but at a lesser extent, as you turn in. You should be
done with your braking as you reach the middle of the turn.
Continue around the corner for a beat before beginning to get
back on the power. Start to unwind the wheel, allowing the car
to move out to the armco on the left as you exit. Get back to
full power as quickly as you can, and then shift up to second as
you go down the straight.
TURN
FOUR:
Entrance speed: approximately 80
mph [129 kph]
Speed through the corner: approximately 65
mph [105 kph]
Arrival time at the corner: 56.45
seconds
Time to negotiate the corner: 3.67
seconds
Exit time of the corner: 1 minute
00.12 seconds
This left-right chicane is tricky because of
three things. First, there is no brake
reference point. Second, there is a significant dip in the track
designed to upset your car midway through the turn. Finally,
there is a large curb on the right hand exit that will try to
rearrange your suspension if you touch it.
With these three things in mind, move the car over to the right
side of the track for the entrance. You'll be in second gear as
you approach it. You need to get a feel about when you should
brake. Approximately four car lengths from the turn
in point seems to be quite good.
Brake moderately for a moment, then ease off the brakes and
begin to turn in. Once you pass the left hand apex you want to
have a straight run out of the corner, so don't turn in too late
or you'll have to back off and turn left quite a bit to avoid
that large piece of curbing.
Easing off the brakes will help you to turn into the corner
better. Aim for an apex at the grass a little pass the midpoint
of the corner. Once you pass the apex, quickly
get back to full power. A straight line exit is important as the
track
dips down here, making the rear end light. If you are still
having to turn left, you'll probably start to slide the rear
wheels to the right. If you correct to catch them you risk
hitting that curb with the front wheels. If you don't correct
you risk spinning. So a straight line is important for a fast
exit.
You should be able to get into third gear as you pass the curb
on your right. Continue in a straight line towards the left side
of the track as you exit the right hand bend.
TURN
FIVE (ESSES):
Entrance speed: approximately 120
mph [193 kph]
Speed through the corner: approximately 100
mph [161 kph]
Arrival time at the corner: 1 minute
3.43 seconds
Time to negotiate the corner: 2.31
seconds
Exit time of the corner: 1 minute
5.74 seconds
Turn five starts the esses. You want to carry
as much speed through all of these
turns as possible. So using the brakes a lot is not a good idea.
Be smooth and you'll be faster. The key to this first right hand
bend is the exit. You want to be as far to the right as possible
in order to ensure a good entrance to the next left hander.
Set the car up on the left side of the track for the entrance to
the turn. You'll be in third gear under full acceleration.
There is a braking reference point, but it is difficult to pick
up, especially if you are right behind another car. Before the armco
starts, on your left, the racing grooves darkens slightly. At
this point brake gently for a moment and start to turn into the
corner. You want to get as much of your turning done as possible
before reaching the apex, and the slight amount of braking will
help turn the car in faster. Stay in third gear after you turn
in, using the accelerator to maintain as much speed as possible,
as you continue towards the apex. You should get your right
front wheel within inches of the last cement-filled tyre. Once
you pass this point, try to straighten the car out as close to
the right side of the track as you can. Make sure you don't get
too much power down as you exit or you'll have a lot of
difficulty staying to the right side of the track.
TURN
SIX (ESSES):

Entrance speed: approximately 100
mph [161 kph]
Speed through the corner: approximately 70
mph [113 kph]
Arrival time at the corner: 1 minute
6.05 seconds
Time to negotiate the corner: 5.65
seconds
Exit time of the corner: 1 minute
11.70 seconds
This left hander follows immediately from the
previous right hander. You'll
be in third gear, hopefully near the right side of the track
coming into this one. There is an access road on your right if
you make a mistake and spin the car coming out of the previous
turn. But, hopefully you won't be doing that.
As soon as you have the car going straight
following the right hander, brake moderately for a moment and
downshift to second gear. It's
very important to be going in a straight line before braking or
you'll probably spin. Once in second, turn in and keep the car
as close to the tyres as possible. If the car is balanced well
and you have a great line you should be able to push quite hard
through this turn, using the power of the engine to keep the car
turning. Make sure that you don't start moving out towards the
right until you are finished with the turn, or you'll have to
slow down a lot to avoid the armco. As you start to straighten
out the car you should be able to get back to full power
momentarily before the following right hander.
TURN
SEVEN (ESSES):
Entrance speed: approximately 80
mph [129 kph]
Speed through the corner: approximately 73
mph [118 kph]
Arrival time at the corner: 1 minute
12.45 seconds
Time to negotiate the corner: 2.02
seconds
Exit time of the corner: 1 minute
14.47 seconds
This right hander follows on from the left
hander you just exited. It is also a
second gear corner, and does not require any braking. You should
be crossing to the armco on the right as you exit the previous
turn. Just before reaching the end of the armco, start to turn
in. An extra blip of the throttle here will help to slide the
rear wheels out to the left and allow you to turn in without
braking. Stay right at the edge of the track as you apex this
turn, even clipping the grass a little. It is important to exit
on the right side of the track or you'll have a really hard time
getting through the follow left hander. If all goes perfectly
you may be able to get back to full power for a moment after
exiting this turn.
TURN
EIGHT (ESSES):
Entrance speed: approximately 80
mph [129 kph]
Speed through the corner: approximately 75
mph [121 kph]
Arrival time at the corner: 1 minute
14.90 seconds
Time to negotiate the corner: 3.24
seconds
Exit time of the corner: 1 minute
18.14 seconds
About midway through the esses now, and you get to this left
hander. The esses now start to open up a little bit, with more
space between them. This means you need a good
exit to make the most of the turn. Like the previous turns, this
one is also a second gear turn, and requires no braking.
You'll
be on the right side of the track after exiting the previous
turn. The transition from turning right to turning left is quite
abrupt and if you're not in total control of the car you will
probably spin and hit the outside armco. So make sure you have
the car under control before turning into this left hander. You
may need to take the previous corner at a slower speed if you
are all over the place at its exit.
Just after the armco appears on your right, turn into the corner
with the help of the engine. You should apex right next to the
last cement-filled tyre on the left. Try and stay on the
accelerator as much as possible as you go through the turn. Once
past the apex, begin to apply more power. Be careful not to get
too much power down too soon or you'll go very wide on the exit.
There is an access road on the right that you can use to recover
if you do go wide. However, if you can stay near the middle of
the track as you exit you'll be able to accelerate much more
before the next right hand bend.
TURN
NINE (ESSES):
Entrance speed: approximately 90-95
mph [145-153 kph]
Speed through the corner: approximately 85
mph [137 kph]
Arrival time at the corner: 1 minute
19.49 seconds
Time to negotiate the corner: 3.69
seconds
Exit time of the corner: 1 minute
23.18 seconds
This right hander is the beginning of the end
of the esses. You need to be concerned
about getting a good exit in order to carry speed down to the
final turn of the track, the Peralta. Braking is not required
here, as long as you don't go too deep into the corner before
easing off the power.
You'll be in second gear (surprise there) as you approach this
turn. Bring the car over towards the left side of the track.
Just after you reach the white line, ease off the power and turn
into the corner. Letting off the power relatively quickly will
help to turn the car. Just
make sure you don't ease off too fast, because you'll end up
slowing too much, or spinning. You should be pretty close to
redline in second when you do ease off, so take this opportunity
to upshift to third gear. This allows better traction going
through the corner, as well as getting rid of the shift before
the final critical left hand ess. Try to keep the car close to
the right side of the track as you approach the apex. Don't get
too close too soon or you'll have to go wide at the exit to
avoid the tyres. Gradually bring the car closer to the tyres,
ending up about a foot or so from the last one, as you carefully
increase your acceleration. Straighten the car out right against
the right side of the track as you exit the turn and get back to
full power.
TURN
TEN (ESSES):
Entrance speed: approximately 105
mph [169 kph]
Speed through the corner: approximately 95
mph [153 kph]
Arrival time at the corner: 1 minute
24.32 seconds
Time to negotiate the corner: 3.81
seconds
Exit time of the corner: 1 minute
28.13 seconds
This final
left hand turn of the esses is all about exit speed. It is very
easy to brake late for this turn, but you will suffer with a low
exit speed, and won't be able to overcome that until you are
back on the front straight. So brake early here.
The
large bush on the right is an excellent brake and turn in
marker. This corner is taken in third, with just a little
braking a moment before reaching the bush. Turn the car into the
corner, aiming for the middle of the tyres on the left. You'll
be barely on the power as you come towards the apex, just enough
to balance the car. Once you pass the apex,
start to put your foot down slowly. Continue to increase your
acceleration as you drift out to the right,
reaching full acceleration about half way across the track. Go
right out to the grass on the right side of the track. Keep the
car dead straight once you reach the edge. Even if you do touch
the grass a little you should be able to keep at full
acceleration as long as you don't turn at all. There is another
access road on your right as you exit. (Actually I think it
connects with the access road just past the pits on the front
straight, thereby forming a shorter version of the track and
bypassing the Peralta.) Once you reach this you can start to
bring the car over to the left.
PERALTA:
Entrance speed: approximately 157
mph [253 kph]
Speed through the corner: approximately 102
mph [164 kph]
Arrival time at the corner: 1 minute
34.24 seconds
Time to negotiate the corner: 11.12
seconds
Exit time of the corner: 1 minute
45.36 seconds
The final turn is a long banked right hander. The banking allows
you to take it much faster than would
normally be the case. If you got a good exit from
the esses, a good opportunity to overtake exists coming into the
turn. You should be able to get up to fifth gear by the time you
reach the braking point. Line the car up on the left side of the
track in preparation for braking just before the sign on the
left.
Just before you reach the sign, brake hard and downshift to
fourth gear. Then ease off the brakes and turn into the corner.
Get back on the accelerator as you turn in, and try to keep some
power on in order to prevent yourself from slowing down too
quickly. Above the white line on the left the banking flattens
out, so make sure you stay below this line, braking a little
more if you need to.
As
you go through the turn, try to get as much power down as
possible. Be careful that you don't push out wide, or start the
rear wheels sliding out to the left. A good balance between
these two point is difficult to achieve, but is the fastest way
through the turn. A constant modulation of the accelerator will
most likely be necessary to achieve this balance.
Just before the front straight comes into view you have to get
back to full power. This point is a little difficult to judge
until you have some experience with the turn. But after a
practice session you should have a good idea of when you can get
back on the power safely. If you do it
right, you won't get any oversteer or understeer. A slight drift
may result, which is fine. Let the car go right out to the armco
on the left as you exit the turn under full power. You should
reach the wall just
after the pit entrance on the right, and be able to continue
down the front straight under full acceleration. You won't get
into fifth until after the start/finish line.
A good exit here will see you right on the gearbox of another
car. However with such a long front straight this may not be a
good thing if the car you are trying to pass is only slightly
slower than you. You'll have to pull out to pass them almost
immediately and by mid straight you will have lost any advantage
the draft gave you. Worse still, they could get behind you and
draft you right into turn one, and repass you. So exiting the
Peralta a couple of car lengths behind the car ahead is best.
This will allow you to catch them by mid straight, and not give
up the advantage gained from the draft or allow them to repass
you into turn one.
