The quick turnaround is due to the fact that the crash didn't cause as much damage to the car as initially thought. Ben Bowlby, the car's designer, tells us that while the accident looked severe it didn't compromise the integrity of the chassis.
"There was skin damage to an enormous number of parts – both sides of the nose, the side pods, the tail, one mirror – were all damaged, but the chassis wasn't other than a few scratches," he tells us.
The suspension system and engine have also been swapped out so as to have a fresh start before the race. In all the repairs took right around 24 hours.
