Chinese GP Friday Practice |

Kimi Raikkonen (Ferrari) has used Bridgestone’s medium compound Potenza F1
tyre to set the fastest lap time on the first day of running for the Sinopec
Chinese Grand Prix at Shanghai International Circuit.
Raikkonen completed his fastest lap, a 1min 36.607secs, in the final minutes
in the afternoon’s 90 minute practice session. He was just six thousandths
faster than his nearest competitor, Fernando Alonso (McLaren Mercedes), who
set his fastest lap half way through the session, also using the medium
compound.
The morning practice session also saw Raikkonen fastest, with a 1min
37.024secs, this time using Bridgestone’s hard compound. Second fastest in
this session was Alonso once more, using the hard compound to set a time
eight hundredths slower than Raikkonen.
Shanghai provided a challenge for all of the teams with the nature of the
circuit, with two long straights and a technical section, meaning it is
difficult to find the correct compromise in set-up. Today was the first day
of running, so it was particularly harsh on the tyres with the left hand
front tyres suffering in particular.
Hirohide Hamashima - Director of Bridgestone Motorsport Tyre Development,
said:
“To start with the circuit was very dirty today and drivers complained of a
lack of grip. However, the circuit soon improved and the drivers were able
to feel this improvement, although they still wanted more grip and many
struggled to find a good set-up. The difference between the hard and medium
compound Potenza was on average around 0.2 seconds, but that depends on the
car and driver. The wear rate on the left hand front tyre was a little
higher than we predicted but it will be no problem for either compound to
complete a race distance. Both grip levels and tyre wear rates should
improve after we’ve seen more running on the track, and we should see an
improvement tomorrow.”." |
