Rory Byrne, Ferrari legendary former chief designer, was at the launch of the team's 2013 car at Maranello on Friday.
He told Auto Motor und Sport he is actually "working full steam" on the Italian team's project for the 2014 car, which will be powered by the all-new turbo V6 rules.
"It's a nice car," the South African - referring to the newly-launched F138 - laughed, "but it's all child's play compared to what awaits us in 2014."
Until then, Ferrari has the 2013 title to win after a so far five-year championship drought, and boss Stefano Domenicali confirmed that his designers have adopted some "extreme solutions" to compete with Red Bull.
"We are just waiting for Newey to complain about our rear suspension," Auto Motor und Sport quoted a team insider.
The German report said the insider is referring to the rear profile that duplicates the 2012 Red Bull -- only more extremely.
