Suzuka and its Challenges
Round 15 of the FIA Formula 1 Championship takes us to
Suzuka Japan, ‘The Land of The Rising Sun’.
Incredibly popular with most of the World’s greatest drivers, Suzuka provides a monumental challenge for both drivers and engineers. The 5.8km circuit has many blind corners due to its spectacular escalation changes, where judging your entry and exit points can be very difficult in an F1 car.

The contrast in each of the three sectors provides a big challenge
in setting the up the cars, as considerable compromises have to be made.
Aero Characteristics of Circuit
Sector One consists of the infamous ‘S Curves’, a series of
five magnificent quick left right corners. The S curves demand high downforce
for a car to be stable through this turbulent sector, quite the opposite of the
other two sectors.
As you can see S1 demands a lot of downforce, yet the other
two sectors are suited for top speed. A medium downforce package will be most
suitable for Suzuka.
Tyres & Strategy
Prime – Hard (ORANGE)
Option – Mediums (WHITE)
Option – Mediums (WHITE)
Tyre wear rates at Suzuka are quite high, hence Pirelli
nominating the two hardest compounds for the weekend.
In 2013, the majority of the grid ran a two stop race with
the same compound selection. Starting on the Option before two Prime stops was
the typical strategy.
In 2014 I would like to see a few drivers attempting to push
the medium tyres a bit longer, so that they can run a one stop and take the
hards all the way to the end. The 2014 Pirelli’s are quite lenient when you run
a less aggressive car set up, and as we saw in Singapore, it could be possible
to push for a one stop… Even if it does require a bit of “Grandma” driving…
The average strategy looks like it will be a two stop race again.

Mechanical Set Up
The continuous high speed direction changing in Sector One
requires a very stable and predictable car. Being able to stay on the optimum
racing line is critically important through this sector, because as soon as you
go off line for one of the S curves, you will be punished all the way up until
mid-way through sector 2.
A low roll centre, precisely set up anti-roll bar and
cambered tyres are some of the things which will be required for a quick Sector
One.
A low roll centre will ensure that the car is stiff and
responsive for the harsh direction changes. It is important to mention that too
low of a roll centre can cause the car to become too ‘stiff’ and could
therefore cause major problems in getting tyres up to operating temperatures. A
stiff chassis causes minimal roll and therefore makes the car slide around much
more as the tyres can’t bite into the tarmac.
The anti-roll bar settings are crucial in making sure that there is maximum lateral stability. Too much roll will cause poor change in direction abilities and too stiff will cause sliding.
The anti-roll bar settings are crucial in making sure that there is maximum lateral stability. Too much roll will cause poor change in direction abilities and too stiff will cause sliding.
As the cars go through the S curves and 130R, they will be
subjected to around 3-4G’s of lateral force. This induces a large amount of
rolling torque, and it is very important that the tyres maintain maximum
surface area in contact with the ground, which is why cambers will have to be
carefully calculated.
