The F1 2018 season could be a humdinger 

#2 Ferrari

Raikkonen was the last Ferrari to be World champion Driver's champion

Sebastian Vettel:

Tied at four Formula One driver's titles with Hamilton and Alain Prost, and within touching distance of 100 podiums, motivation is not an issue.

If Ferrari are there or thereabouts of Mercedes, another battle with Hamilton is in the offing. Yet, if he doesn't win the title this year with such an effective machinery at his disposal, Vettel's stock will come down.

Kimi Raikkonen:

Needs to start strongly to push his second driver status out of the equation and mount a title challenge. His Ferrari was rapid in the winter testing.

The Iceman's win drought stretches back to the 2013 Australian Grand Prix, that too with Lotus! Nothing will delight his legion of fans more than him winning and promptly hanging his helmet.
