After the lengthy winter break, it is lastly time to arrange for the primary race of the brand new System 1 season, the Bahrain Grand Prix. There are some acquainted faces up entrance, however even in qualifying completely different tire choices are proven. So what strategic choices do the groups have on race day in Sakhir? Chris Medland takes a glance…
What’s the quickest technique?
It actually will depend on how every workforce treats their tyres, however the quickest choices all appear to be two-stop methods with varied mixtures accessible on the subject of the compounds used. The most important limitation is put on from the rear tires, not the tire put on itself, inflicting lack of lap time as drivers wrestle with traction.
Whereas Pirelli’s softest tire presents a transparent efficiency benefit, the C3 additionally wears closely and wears far more slowly than the C3, whereas the medium C2 wears rapidly. Which means that the arduous compound – C1 – is an effective possibility as it’s far more constant and would not have too many efficiency gaps in comparison with C2.
Add all of that up and the quickest technique is to begin with the delicate tire to have the quickest tire accessible throughout the first laps when the pitch is crowded.

After about 18 laps of racing, the primary pit cease can be to change to arduous tires after which run to a pit window between Lap 35 and Lap 42 earlier than returning to delicate tires for a dash to the flag.
That is the technique Crimson Bull and Williams will use, as they exhausted certainly one of their arduous compound tire units in follow 3, which implies they cannot make the following most suitable choice. All groups used a variety of settings earlier within the weekend, with the intention to keep away from it if potential.
How a couple of completely different possibility for the highest 10?
Beginning with the softest tire is nearly sure for these within the entrance half of the grid as a result of it offers a bonus off the road. Selecting one of many different compounds means risking dropping positions on the outset that could possibly be extraordinarily tough to regain because of the slim nature of the course, even on a observe the place we’ve got seen nice races and loads of overtaking previously.
However for any workforce experiencing larger ranges of degradation, or if the observe itself is not as mild with the tires as one may count on, then there’s an alternate for the ultimate race. If the primary pit cease needed to be as early as Lap 10 or 12, then two units of arduous dough can be used to succeed in the end in two races of comparatively equal size.

Doing so permits drivers to push the tougher tire a little bit tougher, whereas additionally opening a wider window for the second pit cease to react to the tide of the race.
Conversely, if the degradation ranges are decrease than anticipated in spite of everything different observe runs have taken place, then transferring the primary stage nearer to Spherical 20 could imply avoiding the C1 tire altogether.
Three phases which can be largely equal can result in a soft-medium-soft technique – however this may solely be tried at very low distortion ranges, in any other case medium can be slower than arduous even at a comparatively quick margin.
What are the choices for the decrease half of the sector?
To essentially combine issues up, groups may think about using all three parts throughout the race if the observe develops rapidly. Once more beginning on delicate floor, as a consequence of a better tempo within the early hours, after the primary race of 12 to 16 laps, a change to the arduous tires specified within the quickest technique may be made.
But when degradation ranges drop because the race progresses, then mid-end could also be an possibility for the race.
Even so, the offsets are small in these methods, so for a rider beginning arduous from the again and operating lengthy can be a cornering ball. This will unlock the potential to pit stops and save time by leveraging a Security Automobile or related occasion, however it is going to additionally present different groups with invaluable knowledge on how the arduous tire is performing.

The three-stop technique can also be a comparatively fast technique by way of race time – utilizing as delicate dough as potential – however groups usually tend to shrink back from the choice to make extra pit stops as observe place continues to be a precedence.
If degradation ranges are low, the single-stopper is a extra probably different, however on delicate tracks the primary lap should cross a minimum of 20 laps earlier than transferring on to the arduous ones for the rest of the race.
Wait, however what’s the climate doing?
You could not imagine it, however there was actual rain in Bahrain earlier within the week, and dealing with ranges have been decrease in follow 1 than initially of pre-season testing because of the preparations for the race weekend.
However since then, the climate has been constantly good for groups to get good knowledge, with heat days and cooler evenings, with wind pace decrease than on some days throughout testing.
