2. Apply the principles of engineering science to the design and analysis of the above systems and components;
3. Demonstrate a detailed knowledge of the operating characteristics of key elements of the drivetrain;
4. Explore alternative approaches to the dynamic modelling of a drivetrain;
5. Describe important performance and refinement issues.

Learning outcomes
On completion of this module, students should be able to:
1. Demonstrate an in-depth knowledge and understanding of the design and function of the main components and mechanisms found within an automotive drivetrains.
2. Demonstrate understanding of concept and system design and differences in drivetrain for electric, hybrid and internal combustion propelled vehicles.
3. Evaluate critically and demonstrate an awareness of the link between system performance, energy requirement, sustainability, maintenance, recycling and customer expectations that together drive the process of system development and integration.
4. Select appropriate components from catalogues with which to develop an electric or hybrid drivetrain unit capable of meeting a given specification.
5. Undertake the design of selected components within a drivetrain system taking into consideration aspects of energy storage, prime mover, load, stress, system performance, materials and operating conditions, demonstrate analytical and problem solving skills.
6. Apply scientific principles and modelling methods to the detail design of the power transmission elements for steady state and dynamic load cases to provide an assessment of durability and understanding of methods limitation.

Upon successful completion of this module the following UK-SPEC learning outcome descriptors are satisfied:
