So mercedes are bringing major updates for the W13 to miami. Images from the race and f1technical.
1) Rear wing: this is a really big one and is a proper step at drag reduction and should get mercedes alot more speed in 2 key areas:
a) a smaller main plane so alot less drag because they had the deepest wing throughout the whole field.
b) A wider DRS flap, merc used to have a really small drs flap because of the contours of their high downforce wing. This should help the power of their DRS as well.
2) New front wing: They have multiple versions of their front wing with tweaks near the end plates to help manage tire wake and reduce drag and sensitivity of the wing when ride height drops under braking and increased down force:
3) Revised beam wing with tapering and twists on the ends: this helps cut back drag and attempts to reduce high speed porpoising
4) Major weight savings: Apparantly they were 15 kg over weight at the start of the season, then in imola they loss 5kg, more weight savings this weekend.
5) Not sure if they did anything with the floor yet, but this should be their key area of focus.
Here is an image:
Lets see if these changes help mercedes close the gap.
