Drivers Lewis Hamilton and Nico Rosberg unveiled the German team's new W05 car on Tuesday as pre-season testing got underway in Jerez in southern Spain.
Mercedes were second behind the dominant four-time driver and constructor world champions Red Bull in 2013 after winning three races.
And significant technical rule changes for the new season promise a much more closely-fought title race for the coming season.
"It is always exciting to pull the wraps off a new car for the first time, but even more so at the start of this momentous 2014 season," said Wolff.
"Lewis and Nico begin the season hungry for success and I am confident that our team will benefit thanks to the continuity of their work during the winter period.
"We have positive momentum after our second-place finish last season. Our clear target is to continue building our team and we aim to deliver on every single race weekend in 2014."
