With more than
80% of the lap spent on full throttle, Monza is known as the temple of
speed. No better place then, for Pirelli to announce the first-ever road
tyre directly derived from Formula One. Among the guests in attendance at
the P Zero Silver presentation held in a spectacular hangar close Pirelli‟s
HQ in Milan were Vodafone McLaren Mercedes driver Jenson Button and Ferrari
team principal Stefano Domenicali.
"I think the tyre is key to the performance of a car," said Button at the
event. "I personally feel that Pirelli has done a great job in bringing so
many different types of tyre that work in so many different scenarios. It‟s
been fantastic working with Pirelli and I really enjoy the relationship we
have. It‟s definitely been more fun this year. If you look at the amount of
overtaking we have now, it not all down to the Drag Reduction System and the
KERS. A lot of it is down to the tyres. Formula One is in a great place
right now; the most competitive it‟s been since I've been involved in the
sport.
The
5.793-kilometre lap of Monza is sure to be even quicker this year thanks to
an extensive DRS zone during qualifying that covers 74% of the lap. The
higher the speed, the more energy is transmitted through the hard-working
tyres. We take a closer look at exactly what the rubber goes through during
a typical lap of Monza…
THE TRACK
After building up speed, the drivers are hard on the brakes for the first
corner, the Variante del Rettifilio, shedding 250kph in about three seconds.
The drivers are travelling at more than 300kph on bumpy asphalt, which makes
it hard to hold the ideal line under braking. The energy dissipated helps to
maximise the grip available but generates temperatures on the tyre tread
that peak at 150 degrees.
One of the key corners, and a good place to overtake, is Roggia. Taking the
ideal line, the car uses a lot of the kerbing, putting a huge amount of
stress on the carcass of each tyre. While it may not look so dramatic from
the outside, the reality is that the drivers and cars really feel the
impact. The internal structure of the tyre is particularly rigid, reducing
the risk of sliding and ensuring the maximum driving precision.
Another famous
part of the track is the Variante Ascari: part of a sequence of corners
taken at high speed. On the entry to the corner, the tyre determines how the
car turns in and the amount of grip it can generate through the corners. On
the exit, the grip from the soft tyre in particular allows the best possible
traction to utilise the power from both the KERS system and the engine.
Coming into Parabolica the drivers change down into third gear for this long
right-hander that marks the end of the lap. The car tends to slide towards
the outside of the corner. There is little aerodynamic grip, so the driver
has to work with the throttle and the steering to hold the ideal line. Then
it‟s back on the power once more and into the start-finish straight again,
accelerating up to 330kph in seventh gear.
PIRELLI’S P ZERO SILVER TYRE
The Pirelli P Zero Silver tyre, which will be available as a limited edition
from Spring 2012, follows on from the Italian firm‟s tradition of using the
lessons learned in motorsport for the benefit of everyday motorists.
The P Zero
Silver tyre is the hard compound tyre in Pirelli‟s Formula One range,
combining performance with durability, and these are also the values behind
the new P Zero Silver for high-performance sports cars on the road. The P
Zero Silver will slot in alongside the current P Zero range, consolidating
Pirelli‟s position as the world leader in the Ultra High Performance sector.
The P Zero Silver shares the same modelling process as Pirelli‟s grand prix
tyres, using cutting edge mathematical simulation to finalise the design of
the tyres under a wide range of road conditions.
The new tyre also shares the same development and production technology for
its compound and construction as the Formula One tyres. In particular, the P
Zero Silver tyre will be produced using the latest MIRS (Modular Integrated
Robotised System) technology at Pirelli‟s Settimo Torinese plant: the
research centre where all the current Formula One compounds are developed,
before being put into production at the Izmit facility in Turkey.
PIRELLI IN MILAN
Pirelli has been based in the northern Italian city of Milan, around half an
hour from Monza, since Giovanni Battista Pirelli founded the company in 1872
– but the Italian tyre maker „s head office moved to its present site, in
the Bicocca district of Milan, in 1907.
The company‟s buildings were housed within the „Pirelli Citadel‟ off Viale
Sarca, shaped like an ancient fortress, which can still be seen today. By
the end of the 1930s, the factory had reached its peak in size and by 1950
there were more than 12,000 employees. It was a real village, which even had
its own railway line to transport products between the warehouses.
New methods of tyre manufacture meant that a cooling tower was needed, as
Pirelli built an on-site power station in 1957. An enormous cooling tower
emerged, which became a powerful symbol of Pirelli‟s industrial presence in
Milan, supplying tyres for all of Italy and beyond.
A fire in 1962 destroyed a large proportion of the factory, and with the
onset of automation, new factories were opened that were more suited to
modern production techniques. Throughout the 1970s and 1980s the factory
declined, so it was clear that drastic action was needed.
On 26 April 1985, work began on "Project Bicocca": the old factory buildings
were pulled down and a new cutting-edge research and development
headquarters was created. A total of 20 architects from countries as far
afield as Japan and the USA contributed to the project, once more giving
Pirelli a stunning headquarters. In these high-tech surroundings, Pirelli‟s
Formula One programme was born at the end of last year.
Not all of the
old buildings were destroyed though: the iconic 46-metre high cooling tower
was incorporated into Pirelli‟s main headquarters building and now hosts
meeting rooms and offices: a spectacular centrepiece symbolizing Pirelli's
past meeting its high-octane present. |
