Ferrari team principal Marco Mattiacci says he would like to see Formula 1's engine regulations relaxed during a season.
Engines are currently homologated prior to the start of a season, with tweaks only permitted for reliability or safety reasons. The same rules will apply for the 2015 season and this is something which Mattiacci would like to see changed.
"Yes, in a certain way - not as rigid as it is today," he is quoted by ESPN when asked if he'd like the regulations eased.
"I would like a certain amount of opportunities a year to work on the engine."
Ferrari's boss added that relaxing engine rules was something discussed between senior figures during a meeting at last weekend's Belgian Grand Prix.
"As you very well know we keep discussing about how to improve - if it's needed - every area of the Formula One product," he said.
"[At Spa] we had a fantastic race. But I suppose there are certain areas, the DNA of Formula One is innovating, innovating and catching up with the best one and being as fast as the smartest one.
"That's what I will keep, as Ferrari, insisting, and one of the areas is engine freezing."
Mattiacci's Ferrari team has endured a difficult season, with the engine department having been restructured following Luca Marmorini's departure as engine chief.
Ferrari is the only engine supplier without a race win under the new regulations, with clients Marussia having scored just two points, while their other customer Sauber has yet to score.
