The course this year extends the range and depth of the material covered in the first year. It introduces new topics and some previously treated topics are developed further and their application to vehicle technology is emphasised. A knowledge of the engineering science principle, as outlined below, is essential to a full understanding of modern motor vehicle technology in all its diversity. Professionals in the transport sector need to be able to draw on such knowledge in order to solve problems more effectively and to understand more readily future technological innovations. This module should run in parallel with Automotive Science Laboratory 2 (SCLAB2000)
