Mercedes team principal Toto Wolff has again declined to reveal where the manufacturer has spent its development tokens on the W12 this season to avoid what he has described as the "war on information".
Pre-season is always one of the most intriguing periods in F1, and the past couple of weeks have been no different despite the bulk of this year's cars a carryover from last season.
But with the new rules having a significant impact on downforce, the machinery was cleverly disguised in certain areas when they were launched so as to avoid giving away any secrets.
Mercedes went one step further than the majority of other teams by opting not to confirm where it had spent its development tokens.
Pressed on the matter again, Wolff said: "Not everything needs to be put in the public.
"This is also a war on information, a competition of information, and I'm sure you haven't seen all the cars in the specification they are going to be raced in Bahrain, so that is part of it."
