Mc Laren MP4-27 Launched Proves Controversial

McLaren has
unveiled this season's Formula One car, the MP4-27, at the McLaren Technology
Centre this week and the team is bracing itself for a fight with rivals over
its bullish interpretation of the F1 regulations.
The car
closely resembles last year's vehicle, but has a more
"tightly-waisted" rear bodywork that aims to improve air flow to the
rear of the car, and a revised cooling system that re-directs the gearbox
oil-cooler. The U-shaped sidepods on the car have been redesigned to comply
with the Federation Internationale de l'Automobile's new exhaust regulations,
which stipulate that the tailpipes must be designed to ensure that the
aerodynamic effect exhaust gases have on the car is kept to a minimum.
The focus for
the design for the 2012 season car was to be less conservative in the
interpretation of the F1 regulations than it had been in previous years. Geoff
McGrath, managing director of McLaren Applied Technologies, admitted to
Autosport that the team has paid the price for being overly cautious in
previous years.
Last year's
car was criticised by the McLaren drivers, Jenson Button and Lewis Hamilton,
for being unreliable -- especially at the start of the season. Hamilton said in
the Guardian in April 2011: "If you really, really knew how bad the car
was behaving in the winter … you would get to 10 laps if you were lucky. The
reliability was a disaster. McGrath says that the new car features innovations
that could potentially attract protests from rivals. In previous years, exhausts
were directed over the rear of the car's floor, speeding up and smoothing the
airflow and therefore increasing downforce and cornering speed.
Director of
engineering Tim Goss explains: "The regulations around the exhausts are
very prescriptive: the exhausts must now exit within a very tight space at the
rear of the car in order to minimise their aerodynamic influence. The final
100mm of the exhausts must be cylindrical -- so they can no longer be oval, or
flattened -- and must be sited at a particular vertical and horizontal angle -
between 10 and 30 degrees upwards. That's to direct the exhaust exit away from
the floor."
Of this
year's car, Hamilton says: "I've been keenly following the development of
MP4-27 over the winter and I've been really encouraged by the results and the
data that the engineers have been showing me. The drivers begin track testing
of the MP4-27 in Spain on 7 February, 2012.
