Ferrari is happy with F1's engine formula for the future.
The FIA had earlier announced controversial four-cylinder engines for 2013, but in the face of opposition from teams and engine makers has now agreed to let the sport be powered by 1.6 litre V6s in 2014 and beyond.
But after the FIA rubber-stamped the V6 compromise this week, team boss Stefano Domenicali said: "This decision is good for the sport.
"We now have the necessary time to prepare for this new project," he is quoted by the German news agency SID.
It is believed Renault and Cosworth are also happy.
"It is good that the compromise reached has been confirmed by the World Motor Sport Council," agreed Mercedes-Benz's Norbert Haug.
