Pirelli & C S p A : 2021 Bahrain Pre-season Test

'Throughout all three days, all the compounds performed well and no problems such as graining emerged: only light abrasion on the softest compounds. As well as the weather conditions, lap times were naturally influenced by the different fuel loads run by each team, making performance comparisons with last year's race and free practice at Bahrain very difficult. It's also difficult to accurately assess the performance difference between the compounds, due to track evolution. The easiest to tell is probably the gap between the C2 and C3, which is around 0.5 seconds, while the gap between C3 and C4 is bigger than expected, with the C4 driven by many cars when the track was at its fastest. Now we look forward to the beginning of a season that will be the last one run with 13 inch tyres before the move to 18-inch tyres in 2022, for which a series of development tests has been planned throughout this year'.
