Paddy Lowe reckons Mercedes W05 will be tested next weekend as the Silverstone circuit will put the "aerodynamic performance to the very limit."
Mercedes' W05 has been the car to beat throughout this year's Championship.
Nico Rosberg and Lewis Hamilton have claimed seven out of eight race victories of which six of those have been 1-2 results.
The team's latest triumph came at the last race in Austria where Rosberg and Hamilton beat the Williams' of Valtteri Bottas and Felipe Massa.
"It was a great result for the team to get another one-two finish in Austria - even more so considering our below-par grid positions," said Mercedes executive director Lowe.
"For Lewis in particular, to come through from ninth place and be fighting at the front was an impressive performance, while it was also immensely satisfying to see seven of the top ten cars powered by Mercedes-Benz.
"While it was a less than straightforward weekend for us, the event itself was fantastic. We very much enjoyed returning to Austria and will look forward to going back there again in the coming years."
Lowe, who is in charge of the technical side of the team's operation, reckons Mercedes will have a new challenge at Silverstone as the nature of the track will test the car's aerodynamics.
He is, however, hopeful that Rosberg and Hamilton can once again shine in front of Mercedes' home crowd.
"For now, though, we look ahead to Silverstone and a different challenge to anything we've seen so far this year. It's a very fast circuit layout which tests aerodynamic performance to the very limit.
"We demonstrated our competitiveness there last year with victory for Nico and equally with pole position for Lewis - who was extremely unfortunate not to achieve the result he deserved with his tyre failure in the race.
"We're very much hoping that our strong form will continue and are looking forward to seeing another tightly contested battle between our two drivers.
"The circuit is a matter of miles from our factories at Brackley and Brixworth, so we're determined to put on a great show for everyone in the team as well as the fantastic British fans."
