Another dramatic day of testing has come and gone, so what have we learned? Ferrari were fastest ahead of the Mercedes, with the Italians flying round the circuit like a red blur. The Bulls picked up the pace after their disappointment, with teen wonder kid Verstappen throwing himself firmly in third. However, it was a mirror image for Williams. After such a strong performance yesterday, the rookie Stroll took the car for a spin, only to literally spin and damage the car. And McLaren’s engine problems continued, which leaves you asking the question: what do they actually do at Honda?
