Several F1 drivers voiced complaints about Pirelli’s new hard tyre introduced at the Circuit de Catalunya this weekend.

Kamui Kobayashi said: “The new superhard compound gives you the feeling you are driving a totally different car. They are so slow.

“This is going to be tricky for everyone and might produce interesting tyre strategies in the race.”

Lewis Hamilton was more critical, describing them as “disastrous”.

The new compounds were supposed to allow drivers to run slightly longer stints, opening up new strategic options.

But the compound has proved very slow. Rubens Barrichello was told during the course of the second practice session they were around two seconds per lap slower.

Here is the data from the second practice session:

Longest stint comparison

  • The harder tyre appear to last reasonably well – see Mark Webber’s stint from the beginning of the session below. But they are clearly lacking in performance – though consistent, his lap times are in the 1’29s
  • Jenson Button couldn’t mnake the tyres last as well as Webber could, and Ferrari didn’t do a run of comparable length

Ultimate lap times

  • Unusually, Sebastian Vettel found himself behind his team mate, although he does have some time in hand
  • Fernando Alonso was delayed by Nick Heidfeld on his fastest lap, and should be able to go at least two tenths of a second quicker
  • The ultimate laps of both HRTs were outside 1.7% of Webber’s time by over a second. They will be hoping the fastest cars do not use soft tyres in Q1 or they may not qualify

Complete practice times

  • Both Virgins were well clear of the HRTs. Colin Kolles said: “The time sheet doesn?t look too good today but I?m positive because I know what we have done and I think tomorrow we will see the real performance of the car. We only did long runs and were not running on low levels of fuel.”
  • Sauber looked promising in both sessions and on the strength of this should be in contention for places in Q3
  • Despite their updated car Force India are languishing among the Lotuses. an Sutil believes there’s more performance to come, saying: “I ran with all our new aero parts this morning and in the afternoon, but to be honest we haven?t managed to find the sweet spot yet.”
