With Ferrari dominating in the first pre-season test, Mercedes are now feeling threatened. As the second test gets underway in Barcelona, the Brackley team flew in a whole slew of upgrades.

Some of these changes include upgrades to the nose, front wing, floor, sidepods and t-wing to name a few.

It certainly looks like Mercedes and Lewis Hamilton are serious about taking their 6th title. The W10’s nose looks vastly different from before and other additions have been made to the car.

So the big question is, are these little alterations the key for Mercedes to unlock the W10‘s full potential, or do Ferrari have an ace up their sleeve?

Also, do no discount the Red Bull duo of Max Verstappen and Pierre Gasly from springing a surprise.
