For Pirelli’s home event at
Monza, the P Zero Orange hard and P Zero medium tyres have been nominated:
the same combination as seen at Spa for the Belgian Grand Prix. However,
while Spa exerts plenty of lateral energy on the tyres, Monza is all about
longitudinal energy which puts considerable forces on the tyres and requires
high levels of mechanical grip. With set-up being a compromise between the
fast and slower sectors of the circuit, the tyres play a crucial role at
Monza, with several opportunities for strategy.
The circuit dates back to 1922, and it was also the scene of Pirelli’s first
grand prix championship win, when Gastone Brilli Peri claimed the title in
1925 with an Alfa Romeo. Having been through several incarnations over the
years, the modern circuit is now very different to the original layout,
although the historic banking of the very first track remains as a monument:
part of the unique character of Pirelli’s home circuit.
Paul Hembery: “Monza is obviously our home race, only around half an
hour away from our headquarters in Milan. It’s very easy to see why the
place has been called ‘the temple of speed’: it’s actually the quickest
circuit that we go to all year, and the long straights and fast corners put
plenty of energy through the tyres. This means that overheating and
blistering can be a problem if not controlled. So correct tyre management
can have a very important effect on the race and the strategy, and this is
something that the teams will assess during free practice on Friday. Not
only the performance of the tyres is tested here but also the durability, as
there are plenty of high-speed impacts with the kerbs, which represent
another important aspect of this race. Monza is one of the most popular
races of the year, with lots of tifosi, and we are very much looking forward
to it.”
Jean Alesi: “I love Monza and I’ve had so many fantastic moments
there. I’ve been on pole twice and I reckon I have probably spent half my
Monza ‘life’ leading the race – only for mechanical problems to get in the
way. Tyre-wise, it’s a very challenging race and it’s the fastest lap of the
year, so it’s quite clear that you need the hardest compounds available. The
cars run low downforce, so they can slide quite a lot in the corners and
limiting this is a key to getting the best life out of the tyres. Getting
the tyre pressures at Monza right is very important too: you need to make
sure they are not too low. This is crucial for the kerbs in particular,
which you hit hard. These days, the driving style means that you practically
take the chicanes in a straight line, so this is actually even more
important than it used to be. Monza is all about the tifosi – and the
support I always enjoyed there as a Ferrari driver was fantastic: you could
really feel it. In terms of atmosphere, Monza is just incredibly special.”
The circuit from a tyre point of view:
About 75% of the lap at Monza is spent on full throttle but there are also
some heavy braking areas, which place equally heavy demands on the tyres. On
the approach to the first chicane, the cars brake from 340kph to 80kph in
just 150 metres.
As well as flat-out straights there are also some very quick corners: the
drivers experience 3.7g at Parabolica, which is also transmitted through the
tyres.
The three areas that work the tyres hardest at Monza are the first chicane
(characterised by heavy braking), the Variante Ascari (with rapid changes of
direction) and the famous Parabolica: a long and open corner that generates
big lateral forces.
Technical tyre notes:
Top speeds on the straight at Monza peak at around 340kph depending on
set-up. The resulting force can heat the tyre up to 130 degrees centigrade:
the peak temperatures seen all year.
The top two last year (Hamilton and Perez) used a one-stop strategy, with
Perez claiming the runnerup spot from 13th on the grid. Hamilton started on
the medium and switched to the hard, while Perez did the opposite. The
highest-placed driver to use a two-stop strategy was Michael Schumacher, who
finished sixth for Mercedes.
Teams run a specific aerodynamic package for Monza, usually with the lowest
levels of downforce of the year. This puts the emphasis on mechanical rather
than aerodynamic grip.
Meet the Pirelli F1 Team: Dario Marrafuschi, modelling and application engineer
Dario, one of Pirelli’s dedicated army of advanced engineers, is Milan born
and bred, having studied engineering at university there. After graduating
in 2000 he went straight into Formula One. He was employed by Ferrari
initially in the vehicle dynamics group; then became a tyre engineer and he
finally engineered the car for the test team from 2006 to 2008.
He joined Pirelli at the end of that year as circuit racing manager,
overseeing all of Pirelli’s track-based activities. In 2010, Dario joined
the growing R&D division as it started work on the Formula One project,
specialising in modelling and pre-development. As well as keeping a close
eye on the tyres for this year, Dario concentrates on future development of
Pirelli competition tyres through mathematical models and simulations. While
his computer crunches the numbers, he keeps himself busy by jogging and
cycling across the Alps in Italy. He is a seriously fit man, having once
been a runner in regional competitions in Italy. These days he doesn’t have
the time: as well as work, his wife and two-year-old son make sure of that…
