The name is a combination of the current year and the number of cylinders in their V8 engines.
The V8 units, which were introduced in 2006, will be replaced in 2014 by turbo-charged V6s.
The Italian outfit, who finished second to Red Bull in 2012, will launch their car at their Maranello factory ahead of testing which starts next week.
Ferrari is the only team to have competed in every year of the Formula 1 World Championship and the F138 will be the 59th car to be built by the Scuderia.
The Italian team has won 31 championships – 15 drivers’ and 16 constructors’ – 219 race victories, 207 pole positions and 228 fastest laps.
