Mercedes says a "wacky" and radical set-up approach implemented in Austria may have hurt its car's race pace and impacted tyre degradation.
Valtteri Bottas and Lewis Hamilton qualified a couple of tenths behind pacesetter Max Verstappen on Saturday, but on race day the Red Bull charger sailed off into the distance to take his fourth win of the 2021 season.
But Verstappen's 35-second margin over Hamilton at the checkered flag was particularly impressive and validated once again Red Bull's edge over Mercedes.
But Andrew Shovlin, the Brackley squad's trackside engineering director, believes that Mercedes' decision to "be a bit brave" and to opt for a radical set-up approach at the Red Bull Ring may have weighed on the race pace of its W12 Black Arrow.
"It is a difficult and quite peculiar circuit and Red Bull are normally strong here," said Shovlin.
"But we were also exploring a fairly wacky direction with the set-up, as a radical approach which I think was maybe a bit better on a single lap.
"The question that remains is whether we’ve hurt our degradation and we need to look at that in the next day or two.
"Lewis, before he came here, was doing a lot of work in the driver-in-loop simulator, and it looked like an interesting direction.
"But an important part of this year for us is adapting well to every track and we do need to be a bit brave and original with set-up direction to do that."
