The teams were able to try out the 2014 range of tyres over the four-day test, as well as the ‘winter’ compound. Pirelli also supplied each team with an experimental medium set for next year, to gauge performance when tyre-warmers are not used – as per the regulations for the 2015 season.
Pirelli’s data shows that the supersoft compound is around 0.7s per lap faster than the soft, the soft is around 1.2s per lap quicker than the medium, and the medium is around 1.3s per lap quicker than the hard. However, these gaps will close once the cars are fully developed.
Hembery explained that the teams “were able to learn more about [our] tyres over the four days in Bahrain than they could in Jerez two weeks ago, thanks to increased running time and optimal weather conditions”.
“Although the teams are still at a comparatively early point on the development curve with their new cars, testing data so far indicates that the 2014 tyres are more consistent and durable than their predecessors. As a result, we are also seeing fewer ‘marbles’ on the circuit: one of our objectives at the start of this season”
“However”, he continued, “[the] teams are likely to improve their performance and understanding of the car-tyre package still further in the test to come, which means that the lap time differences we have been seeing between the compounds are likely to come down: especially when the teams discover more downforce as the season goes on.”
He concluded: “We’ve collected plenty of useful data from this test, but of course we are still ready and able to change the specification of the tyres for the start of the season if this is shown to be necessary.”
