Ferrari is reported to have earned 10 hp with the 2018 power unit, despite trying to improve the engine on durability this year.
Drivers will be able to use only three power units in 21 race seasons, and the producers made their way through their hands to bring each track to a level where it can withstand at least seven races throughout the winter.
At the beginning of the season, the Ferrari was expected to be at a similar level with the 2017 power unit, but sources in the interior suggested base improvements in the 062EVO engine to take to Melbourne.
Ferrari, led by engineer technical chief Corrado Iotti, made a special effort to improve their performance at slow and medium speed bends because they thought they could develop more here.
While the team is making some changes this year, one of them is a lighter turbot. This lighter turbot reacts in less time and provides more support for the MGU-H to be able to charge more efficiently.
Ferrari is also doing extra work to get a good performance in the second power unit and fight Mercedes, due to the decline in engine numbers this year.
The Italian team is looking forward to seeing how the current power unit will perform particularly well in the sequential mode compared to Mercedes' new engine.
But the increasing weight of the 2018 vehicle has led to an increase in fuel consumption, and pilots will be consuming more and more fuel at full throttle. This can affect the performance of teams on a runway like Melbourne, or something that can get a headache.
