• INSIGHT: Bahrain Grand Prix Debrief: Your Questions Answered

We asked you to send in your questions about the action-packed Bahrain Grand Prix and grabbed Technical Director James Allison to answer them! Here goes...

Rob Sihra on Twitter asked:

-  Why could Bottas not close down Vettel? Was it car or driver related? What can be done to improve?

James Allison: "The answer is Valtteri did manage to close on Vettel. With three laps to go, we were right up against his rear bumper.

"But, we were not quite good enough to get past him. Probably if the race had been a lap or two longer, it would've been a different outcome.

"We left our charge a little bit too late and weren't able to get the race win."

Anthony Liddell got in touch on Facebook:

-  Did you ever consider splitting strategies or was the plan always to have Valtteri and Lewis on one-stop races?

JA: "At all the races we go to, we have several options for strategy and this one was no exception.

"For both our drivers, we had two and one-stop strategies planned. For Valtteri, the default was a two-stop and with Lewis, the default was a one-stop.

"But, with the way the race unfolded, it made more sense to switch Valtteri to a one-stop, once we saw what Sebastian had done in front of us."

Gaëlle submitted a question on Twitter:

-  Did the fact that Sebastian Vettel never seemed openly worried on his radio about his tyres have an influence on Valtteri's or Lewis' race?

JA: "Thanks for the question, a very relevant one to the outcome of the race.

"We were probably a little bit too slow to recognise the threat that Sebastian was actually going to take the Soft tyres all the way to the flag.

"Had we been slightly quicker to react to it, we probably would've kept more pressure on him around the 35-45 lap mark and we might've had a better outcome as a result.

"We expected him to stop again but he did a very good job nursing those tyres all the way to the flag."

Daniele Zykaj left a comment on Instagram asking:

-  Would Mercedes have been able to manage the soft tyre for 40 laps like Vettel did? Does Mercedes have more tyre wear than Ferrari?

JA: "Who knows, is the answer. You never can tell unless you go and actually do it.

"What I can say is the tyre wear of our car this year has been very good and in general better than the field.

"Whether specifically we could've made the Soft tyre last the number of laps Sebastian did, we would only know by trying.

"My guess is we would, because our car is looking after its tyres very well in the races this year."

Sarina got in touch on Twitter to ask:

-  Did you have to change strategies after the retirement of Kimi and the Red Bulls, or did you just stick to your initial plans?

JA: "The Red Bulls dropped out too early in the race to greatly the influence the strategic decisions that followed.

"By the time Kimi dropped out the dye was cast, really, for the race we were going to have.

"We were committed to a one-stop by then and it would've made very little sense to convert to a two-stop."

Samantha Cookson replied to us on Twitter with:

-  Did Valtteri hold back, or were his tyres too far gone to make a last ditch effort for first place?

"Valtteri did not hold back at any point during the race. He was pushing as hard as we felt we could in order to get the best out of the tyres.

"I think probably we could've guided him to push a little harder earlier, in the laps around 35-45. But Valtteri was still putting down a pretty good lick even then.

"At the end when he finally caught Vettel, he was giving it absolutely full beans. We just ran out of road and not quite enough laps to get the race win."

Len Thomson queried on Facebook:

-  Have you determined the cause of Lewis' radio issues? Did this have an impact on Lewis' driving or strategy?

JA: "Radio communications between driver and team have improved massively over recent years. It's very often a bit like a telephone call in its clarity.

"But, getting a good result like that is ever so fiddly and we need to make sure we have the microphones positioned perfectly in the driver's balaclava.

"We think we had them just a little bit out of position during this race, which meant we had too much background noise on his signal, making it a little bit harder for us to hear than normal."
