Scenes from F1 Testing in Barcelona Day 4
Using the softest C5 tires Pirelli makes, Nico Hulkenberg gave Renault something to pound their chest about as the F1 teams wrapped up week #1 testing in Barcelona. In fact the four fastest times were set on the C5 tires with Lewis Hamilton rounding out the top-5 for Mercedes on a set of C4 tires. All five were in the 1m17s bracket.
