A drive unit housing for an electric vehicle comprising: a first housing section defining a first compartment to house an electrical inverter, the first housing section including: a tubular perimeter casing defining a circumference of the first compartment and having first and second open ends, and a cover plate separably coupled to the tubular perimeter casing to cover the second open end; a second housing section defining a second compartment to house an electric motor, the first and second housing sections (40,42) separably coupled to one another with the first and second compartments (22,24) separated by a shared wall, the shared wall coupled to and closing the first open end, and the shared wall being generally circular in shape, wherein: perimeters of the first and second housing sections (40,42) are confined within a generally longitudinal form factor being cylindrical in shape, with the first and seconc housing sections (40,42) being disposed axially to one another along a longitudinal axis of the longitudinal form factor, and the shared wall includes one or more openings extending therethrough to provide electrical connection of the electric motor to the electrical inverter; and a network of fluid pathways extending through the drive unit housing for cooling of the electric motor and the electrical inverter, the network of fluid pathways including an inlet port and an outlet port, wherein the tubular perimeter casing of the first housing section defines recesses (70,72) such that the inlet port and the outlet port are disposed within the recesses (70,72), and therefore do not protrude outside of the longitudinal form factor or past the cover plate, thereby protecting the inlet port and outlet port from unintended damage. a first housing section defining a first compartment to house an electrical inverter, the first housing section including: a tubular perimeter casing defining a circumference of the first compartment and having first and second open ends, and a cover plate separably coupled to the tubular perimeter casing to cover the second open end; a tubular perimeter casing defining a circumference of the first compartment and having first and second open ends, and a cover plate separably coupled to the tubular perimeter casing to cover the second open end; a second housing section defining a second compartment to house an electric motor, the first and second housing sections (40,42) separably coupled to one another with the first and second compartments (22,24) separated by a shared wall, the shared wall coupled to and closing the first open end, and the shared wall being generally circular in shape, wherein: perimeters of the first and second housing sections (40,42) are confined within a generally longitudinal form factor being cylindrical in shape, with the first and seconc housing sections (40,42) being disposed axially to one another along a longitudinal axis of the longitudinal form factor, and the shared wall includes one or more openings extending therethrough to provide electrical connection of the electric motor to the electrical inverter; and perimeters of the first and second housing sections (40,42) are confined within a generally longitudinal form factor being cylindrical in shape, with the first and seconc housing sections (40,42) being disposed axially to one another along a longitudinal axis of the longitudinal form factor, and the shared wall includes one or more openings extending therethrough to provide electrical connection of the electric motor to the electrical inverter; and a network of fluid pathways extending through the drive unit housing for cooling of the electric motor and the electrical inverter, the network of fluid pathways including an inlet port and an outlet port, wherein the tubular perimeter casing of the first housing section defines recesses (70,72) such that the inlet port and the outlet port are disposed within the recesses (70,72), and therefore do not protrude outside of the longitudinal form factor or past the cover plate, thereby protecting the inlet port and outlet port from unintended damage.
