Marussia brought a common aero feature for the high downforce Monaco circuit, a small winglet located on the central zone of the beam wing .
The new rear wing design, launched at last pre session test, has a taller and rocket shaped carapace of the DRS activator and reshaped planes with double flap fasteners instead of three .
At China a small single vertical flow guide was added on top of the sidepod to counter fight the lift created by sidepod’s shape which resembles to a down facing winglet . These vertical vanes are common in F1 since a long time ago. For example Caterham current cars race with a combination of three .
All teams are accustomed to bring new parts at the first European race, so did Marussia. The upgrade package included new floor and modified front wing with a slot-less second flap to favor downforce production . The funnel at the back of the engine cover, which was used in hot Bahraini conditions, was also discarded .
At Monaco the previous front wing spec reappeared once again, but did not make it to race.
A small but apparently significant change occurred on the rear profile of the endplate, so as to change the way airflow interacts with the tyre . Worth’s noticing the new fancy sponsor logo on the endplate surface, which may have no impact on the car’s speed, but beyond doubt ensures team’s future speed .
Marussia struggles to improve performance, targeting to beat Caterham team again this season. First fruits of hard labour arrived at second Barcelona test where a new front wing made debut. The new piece has four flaps in total, instead of three (no 1) to increase car pace in fast turns, the main flap has a redesigned upward step before it joins the endplates (no 2), the small flow conditioner (no 3) is discarded and new endplates (no 4) to suit better the higher tier wing .
