Mercedes nonetheless chasing reply for tyre temperature issue

Mercedes says it nonetheless wants time to totally get on prime of the tyre temperature points which might be influencing its efficiency in System 1.

The German producer has famous a development this 12 months the place its W15 automotive shines in cooler circumstances however, if temperatures go up, it struggles extra in comparison with the opposition.

The workforce suspects that it is a consequence of the automotive placing extra warmth into its rear tyres – which is nice for getting them in the proper working window within the chilly, however has penalties in the event that they fall out the opposite finish and get too sizzling on sunny days.

Mercedes thinks discovering an answer to the difficulty isn’t simple, and it might take a number of growth steps earlier than the outfit will get itself to a spot it’s pleased with.

Trackside engineering director Andrew Shovlin stated: “I feel at tracks like Silverstone, we had a really secure rear finish. In Austria and Budapest, we lacked stability. 

“That is all all the way down to the truth that we appear to be placing extra temperature within the tyres than the others.

“We all know we have to work on that space. We have plans to do this, however that is not the kind of downside you may repair with a single aero replace. It will likely be the results of fairly a couple of developments to try to get on prime of it.”

One idea that has emerged in regards to the tyre temperatures is that it might merely be a consequence of an total lack of downforce – which triggers extra sliding than on different vehicles.

However Shovlin isn’t satisfied that’s what is influencing the traits of the W15.

“In case you checked out Silverstone, when it comes to how a lot downforce our automotive has obtained, it will possibly’t be very totally different to the McLaren or the Pink Bull as a result of in any other case we would not have been in a position to gently draw back within the first stint,” he stated. “So we do not suppose that’s the root reason for the difficulty. 

“In case you have a look at the place individuals are operating their vehicles now, they’re all converging on a reasonably slender window when it comes to what drag stage you goal, and inherently what downforce you get from that. So I feel we’re there or thereabouts in that regard. 

“Clearly that is one of many key areas of growth that can proceed to maintain giving. But it surely is a matter of simply rear tyre temperature, and that is the place quite a lot of our focus is.”

Requested if it was extra a mechanical downside than aero, Shovlin added: “It is simply to do with the way you run the automotive. 

“You would possibly want mechanical instruments that will help you change the way you run the automotive. Nevertheless, you may obtain the identical by affecting the aero traits by the velocity vary, and thru the nook. 

“We do not perceive each facet of what could be totally different with our automotive to theirs, however all we want are growth instructions which might be going to enhance it. We’ll preserve going at that downside till we get to the place we need to be.”
