Renault watch and copy Red Bull engine cover
Renault is the first team to have copied Red Bull's overside engine cover. The team must have looked closely to its fellow Renault powered team as the item very much resembles Red Bull's design. The British team introduced theirs at the last test before the start of the season, while Alonso has been busy trying the item in the second day of Barcelona testing. The team also chose to fit their car with the raced front wing instead of the new one in order to better analyse the performance advantage that the new engine cover brings.
people criticized the idea assuming that it would get effected badly from side winds but i think it may actually help steering in case of a side wind. (oversteer)
no matter what, it is obvious that it helps the teams\' revenues.
