SAKHIR, Bahrain -- Sergio Perez set the pace on the final morning of this week's preseason test in Bahrain, making use of an updated version of the Red Bull RB18 to go 0.4s faster than any other driver so far.
The Red Bull emerged on the final day of testing with reprofiled sidepods, offering tighter packaging around the car's internals as well as a revised opening to the car's floor. Perez used a set of Pirelli's C4 compound tyres to set the fastest time as Red Bull appeared to turn its focus to chasing performance ahead of next week's race.
