Merc say they have ironed out their small reliability issues with the spec of PU they used on second test. They will be running the second test spec PU in OZ. The worrying thing is that Mercs PU is reportedly 70hp more than at the end of 2016!!!!! If that is the case then it's a Merc 1-2 all season as long as they don't mess up Caught a bit of SkyF1 Crofty coverage (OK so Crofy isn't great) talking to Force India bloke. He was saying the even soft tyres could last an entire race!! So drivers wont be able to wait behind someone for their tyres to go off. They will have to overtake on track. IMHO that means DRS will be virtually only way to overtake He did say that FIA looking at DRS zones but the DRS wing will be as effective as before. So looks like, as fans predicted, the new aero won't product more overtaking!!! Roll on Ross, the sooner the better.
