The German team brought a different version of their car.
Mercedes did not immediately start recording the fastest times during the morning part of the first test in Bahrain, but a new hip design made a storm in the paddock. Now the air intakes are much narrower and smaller because it allows less air resistance, but the coolers had to be moved up towards the engine, so this part of the car became a little thicker. Now the W13 has a lot more holes and slots on the chassis because the layout of the elements is probably different as well.
