Mercedes team principal Ross Brawn has played down suggestions that Lewis Hamilton's move to Brackley will put extra pressure on his squad.
Brawn's outfit have flattered to deceive since they won the double in 2009 under the Brawn guise, but the team are expected to take a major stride forward in the next few years after securing Hamilton's signature from McLaren.
Hamilton's move will no doubt lead to an increase in expectations, but Brawn insists outside factors won't be an issue.
"I think all of us are under substantial pressure but a lot of it is pressure you generate yourself," he said.
"I think none of us have handcuffs holding us to this business, so there is pressure at every level. We are trying to go forward.
"Most of that pressure for me personally is the pressure from within - not the pressure from a driver or the pressure from a board."
Formula One will switch to 1.6 litre V6 engines and introduce a more sophisticated Energy Recovery System (ERS) in 2013 and many believe German manufacturer Mercedes will get one over their rivals.
However, Brawn was quick to point out that Hamilton's former team McLaren will get the same benefits.
"Our agreement with McLaren is to supply engines to the same specification. None of us really know how it's going to be in 2014 in terms of engine performance, engine reliability," he said.
"There won't be huge differences. We have a one team policy, a one team principle. Our staff at Brixworth and Brackley work together as one entity and that does bring them closer than can be achieved with a customer, but McLaren are an extremely professional customer.
"Our ambition is to have the best engine in 2014 and McLaren will have that engine as well."
