Lewis Hamilton
(Vodafone McLaren Mercedes) set the marker on the opening day of running for
the Hungarian Grand Prix - the ING Magyar Nagydij - by using Bridgestone's
super soft compound Potenza tyre to set the day's fastest lap time at the
4.38 km Hungaroring circuit near Budapest, for the eleventh round of the
2008 FIA Formula One World Championship.
Hamilton set his time - a 1min 20.554secs - in the afternoon 90 minute
practice session. He was almost two tenths faster than the next driver,
Nelson Piquet (ING Renault F1 Team). Hamilton's team-mate, Heikki
Kovalainen, went third fastest in this session.
In the morning, Scuderia Ferrari Marlboro driver Felipe Massa set a time of
1min 20.981secs, using the soft compound to go fastest by almost four tenths
from team-mate Kimi Raikkonen. Kovalainen went third fastest.
As expected, the Hungaroring proved to be a difficult challenge for drivers
due to the slippery and green nature of the circuit which is seldom used
during the course of the year. Grip levels varied during the three hours of
running today, whilst the weather remained warm and dry, meaning that
Bridgestone's extreme wet and wet tyres were not required. Today's fastest
lap time was almost four
tenths than the best Friday time set last year, a 1min 20.919 secs, set by
Fernando Alonso (Vodafone McLaren Mercedes).
Hirohide Hamashima - Director of Bridgestone Motorsport Tyre Development,
said:
"Today was difficult as the circuit conditions were constantly changing. The
circuit grip improved through the first session and then further
improvements were seen in the afternoon too. As we expected, there was a lot
of tyre graining seen and this was worse on the super soft compound. The
super soft enabled a slight faster lap time with the track as it was today,
although it is too early to
draw conclusions on the wear and degradation. For teams it was very
difficult to find a balance, but if the track continues to improve tomorrow
we should have a better idea of what tyre strategies to expect in Sunday's
race." |
