Mercedes F1 W05 - intercooler advantage 23 April 2014

Another 'secret weapon' that the all-conquering 2014 Mercedes appears to have is an intercooler inserted into the top area of the chassis, circled here in yellow. This intercooler cools the turbocharged airflow that is going into the engine. As illustrated by the blue arrows, airflow from underneath the car's main air intake is passed across the intercooler, reducing the internal air temperature. The cooler this airflow is the more horsepower the engine will generate. With so many different systems on the cars now requiring cooling, this is a real packaging benefit for Mercedes, and one which will be difficult for other teams to copy.
