Apparently they the radiators are higher up. If it is true then they will have needed to get the FIA on board with the regulations. We could be in for a Mercedes steamroller season akin to 2014.If that's true, it will be extraordinary, but it just doesn't seem credible. Where would the radiators (and the cooling) for the radiators go? If they went higher in the car, it would lead to a less favourable weight distribution.
