Formula One governing body FIA has moved to stop drivers for cutting corners and gaining benefits at Turn 2 and Turn 13 of the Sochi circuit by fitting two orange blocks on the exit of the corner.
The tight right-hander is the first major braking zone around the lap and has been the scene of many incidents in the past of drivers running wide, especially on the first lap of the race.
Because of the run-off area on the outside of the corner, going in too quick can result in a better acceleration for Turn 3.
Race Director Charlie Whiting has already warned that drivers are likely to receive drive-through penalties if they repeatedly exceed track limits. Last two seasons drivers have been given new instructions on Saturday on how to negotiate the run-off at this corner.
This should bring sufficient of a handicap for drivers to ensure that there is nothing to be gained by running wide.
A revised note from F1 race director Charlie Whiting sent to teams on Saturday morning said: “Any driver who fails to negotiate Turn 2 by using the track, and who passes completely to the left of the orange kerb element on the apex, must then re-join the track by driving between the two new orange polystyrene blocks.
“Drivers are reminded that having left the track they must rejoin safely.”
Also, the FIA has asked drivers not to use the tricky T12 – T13 complex to be slow on an out lap in an effort to leave space ahead for their upcoming flying lap, as the blind fast corner could cause issues for following drivers. Drivers could face penalties as a result.
