F1 wheel wars: are new rims behind Ferrari success?
Mark Hughes and Bryn Lucas explain how the new design works and why it could be the opening shot in a new round of wheel wars, with Formula 1 regulations giving teams more freedom in their design.
They also consider whether this another example of Ferrari becoming F1's most innovative team, after its rotating 'Macarena' rear wing and clever spotting of a loophole around the crucial rear-end aerodynamics.
Ferrari will remain in the spotlight this weekend as it brings an engine upgrade: can it help Hamilton win for the second grand prix in succession; and does F1 need him to succeed?
Over at Mercedes, the questions of whether it should impose team orders to tackle the newfound threat have already begun. Mark gives his verdict.
