Following Sunday's Grand Prix in Bahrain it is clear the Ferrari's threat on the Mercedes monopoly is very real indeed.
Kimi Raikkonen finished second on the podium, ahead of Nico Rosberg, who suffered a brake failure with just two laps of the race remaining. Lewis Hamilton won comfortably, securing his third win out of four so far this season.
While Sebastian Vettel finished fifth, behind Williams' driver Valteri Bottas, the threat he posed throughout the first stint towards the Mercedes drivers proved how far Ferrari have stepped up this season.
However, three unforced errors throughout the race and a damaged nose cost Vettel the podium, allowing his team-mate to swoop in and pick up the pieces for Ferrari.
It was vital that Hamilton cut off Vettel going into the first corner on the first lap, having seen the threat that Ferrari posed all weekend, where they proved better on long runs and on tyres in free practice and in qualifying.
The Ferraris were the strongest we've seen them so far this season, they are a force to be seriously considered for the championship.
While Hamilton now sits almost thirty points clear in the championship, he has named his main rival for the season as Vettel over team-mate Rosberg.
Rosberg sits in second place in the world championship with 66 points, while Vettel sits hot on his tail in third place with 65 points.
Up for the fight
With four titles to his name, Vettel no doubt understands what it takes to win a championship, and of course, to race the champions around him.
The fight between Hamilton and Vettel has created a great new dimension in Formula 1, where Mercedes aren't as dominate or as far ahead anymore, creating a serious battle for 2015 driver's and constructor's championships.
