The car, which will be piloted by Adrian Sutil and Esteban Gutierrez, was presented during an online launch on Sunday.
Chief designer Eric Gandelin stressed that reliability early on is crucial.
"The radical changes to the technical regulations for 2014 mean that it’s even harder than usual to make predictions for the new season," explained Gandelin.
"We know what kind of package we’ve put together here, and we are happy with what we achieved, but it is difficult to foresee what shape our rivals are in."
"The earliest opportunity to gain an impression of where the teams are in relation to one another will come during testing. The path we have followed with the design of the Sauber C33-Ferrari allows us maximum flexibility, so that we can react quickly."
"It is also clear that reliability will be an important factor in the first few races in particular. So this is an area which we have given very high priority."
Sauber will conduct the Jerez test this week with a roll-out specification of the car, before performance parts are added for the final two tests in Bahrain.
"On the one hand this gives us time to maximise the development of these performance relevant parts, and on the other hand we can run the car during the first test and check all the systems, which we feel is crucial, considering all the technical change," added Gandelin.
