Confident that Ferrari are "doing the right things", Sebastian Vettel believes they can take the fight to Mercedes next season.
Ferrari have been best of the rest behind the Brackley duo throughout this year's campaign, finishing third and fourth in the Drivers' standings.
In a season dominated by Mercedes, Vettel is the only driver aside from Lewis Hamilton and Nico Rosberg to win races, claiming three in his first year with Ferrari.
Next year, though, the former Red Bull driver believes he can add more to his tally as Ferrari are "fired up" to challenge Mercedes.
"I think it has been an upward curve all year long," he told Sky Sports F1.
"If you consider where we were in winter testing – probably something like 1.5s [per lap] behind – and now after a grand prix distance something 10 to 15 seconds behind, I think we are definitely doing the right things.
"We know that there's an awful lot to do. We know that Mercedes is very strong – not just the car, not just the engine, not just the drivers – it's the package.
"But I believe we can be better than them. I believe they are beatable, especially when we get closer. We're very fired up about next year."
The German, though, concedes that Ferrari need to get all aspects right next season if they want to challenge Mercedes.
"We have to. We don't want to play chasing anymore; we want to be the favourites going in and we want to be the dominant force.
"We want to turn it around and to do that you have to simply focus on yourself. Obviously it depends also on the steps others are making but for now it doesn't matter.
"We have to keep our feet on the ground, our heads down and work for ourselves. We know we can improve our car, we know we can improve our power unit; and also from the drivers' side we can do better.
"If we get all of this together, it could make us very strong. But that's 'would, could, should'. For now, there's a lot of work ahead and we focus on that every single day."
