A NEW-LOOK ROLLHOOP INLET
One the most distinctive features on the new W07 is undeniably its new-look rollhoop inlet. The airbox has been widened and is now oval and tilted. It is also divided into three separate inlets – one central duct that feeds cooling air to the compressor, while the other two are narrower and channel air towards what is either an ERS or gearbox cooler and forms an extension of the engine.
The two ducts have the same function as the ear-shaped inlets that Mercedes trialled in free practice in both the US and Mexico. Inside the inlets one can spot small aero elements that aimed at guiding the incoming airflow. This new installation logically leads to the upper part of the engine cover being slightly more rounded.
