Toto Wolff has admitted Mercedes is pushing the boundaries of its efficiency to defeat Ferrari in its tight title battle, in the end resulting in its current spate of gearbox failures.
Lewis Hamilton was given a five-place grid penalty for the Austrian Grand Prix after the gearbox was swapped on his W08 forward of qualifying, earlier than Valtteri Bottas suffered an an identical destiny at this weekend’s British Grand Prix.
Having prided itself on establishing a superior reliability document for the reason that begin of its title-winning run in 2014, Mercedes admits the pattern of failures is a fear for it at this stage of the season.
Even so, Wolff believes it’s merely a symptom of extracting efficiency from its W08 in its battle with Ferrari.
“We try to push each space and extract efficiency wherever you’ll be able to and typically you go one step too far. We broken each gearboxes in Baku and we hope to outlive till after Budapest with Valtteri’s however we did not need to take the chance.
“Now each gearboxes have been modified again to the protected spec, the place we should not be having these issues anymore. But it surely’s simply the brand new actuality and also you simply have to not go away any stone unturned so as to discover efficiency.”
Certainly, Wolff says the ‘maturity’ of the gearbox know-how means it could solely go thus far with efficiency extraction.
“Sadly the gearbox is sort of a mature space and there’s not a lot efficiency you’ll be able to extract, so that isn’t a giant efficiency differentiator. Nonetheless, now we have tried it so as to maximise it, nevertheless it’s not that you’d actually see it on the stopwatch.”
Hamilton completed fourth within the Austrian Grand Prix having began eighth, whereas Bottas will get away from ninth at Silverstone having received final day out in Spielberg.
