With the world champion crew involved in regards to the threat of a reliability failure within the closing phases of the championship, it has opted to suit Hamilton with a recent inner combustion engine for this weekend’s Turkish Grand Prix.
The selection to vary only a single part means Hamilton will get a 10-place grid penalty somewhat than a again of the grid drop that might have come from a full energy unit swap.
Talking about why Mercedes didn’t go for a whole swap, Shovlin stated it felt a full change wouldn’t have provided the advantages wanted to justify it.
Mercedes trackside engineering director Andrew Shovlin advised Sky Sports activities F1: “We’re simulating all of the races till the tip of the yr.
“There’s the steadiness and threat of a reliability challenge, and clearly the factor that you simply positively don’t wish to do is fail in the course of the race after which need to take a penalty anyway.
“Then there may be additionally a efficiency ingredient as a result of the ability models do lose a little bit of horsepower over their life.
“The ten-place penalty is the bit that almost all contributes to that reliability ingredient and the efficiency is the ICE itself, so it’s higher to take 10 locations than to begin from the again.”

Whereas Mercedes may nonetheless decide so as to add extra recent elements later this weekend, particularly if Hamilton doesn’t qualify excessive sufficient up the grid, Shovlin doesn’t suppose it’ll transcend simply the ICE.
“Unlikely actually,” he stated. “There’s loads of pretty intrusive work whenever you begin altering a few of these components in the course of the race weekend, so we’re fairly proud of the choice now we have taken to this point and that’s doubtless on what we’ll persist with.”
Though Valtteri Bottas struggled to make a lot progress up the order after a grid drop in Sochi, Shovlin is hopeful that Istanbul will provide higher alternatives for Hamilton.
He’s additionally conscious of the truth that the world champion staged a formidable fightback throughout a GP2 outing right here in 2006 when he recovered from a spin that dropped him to nineteenth to complete second.
“Understanding how simple it’s to overhaul is definitely fairly arduous as a result of you already know in your individual thoughts that are the tracks which can be good for passing,” he defined.
“Sochi has bought a really lengthy straight however we have been fighting understeer and that made it difficult. However it is a circuit, you’ll keep in mind Lewis in that GP2 race the place he felt there may be loads of alternative right here, so it ought to make for an thrilling Sunday.”
