1. A concrete mixer vehicle comprising:
a chassis;
a cab coupled to the chassis;
a front bumper coupled to a front end of the chassis;
a drum assembly coupled to the chassis, the drum assembly including:
a mixing drum defining an aperture and an internal volume;
a charge hopper positioned proximate the aperture and above the cab;
a chute positioned proximate the aperture, beneath the charge hopper; and
a drum driver; and
an engine module coupled to the chassis and positioned rearward of the drum assembly, the engine module including:
an engine;
a cooling system; and
a hood including:
a housing within which the engine and the cooling system are disposed, the housing having a first end proximate the drum assembly and an opposing second end defining an opening; and
a door pivotally coupled to the opposing second end of the housing and positioned to selectively enclose the opening;
wherein the hood has a top surface; and
wherein the first end of the housing defines an inlet airflow cavity leading to an internal cavity of the hood, the inlet airflow cavity having a bottom surface and an air inlet positioned between the top surface and the bottom surface.
