4. (a) The consideration of sustainability and inclusivity are important in the design of an automotive vehicle. For each consideration, Identify two design features that are commonly implemented in the automotive vehicle. [4 marks) (b) As a professional engineer, you are requested by the Board of Engineers Malaysia to perform life cycle assessment (LCA) by focusing on production of raw materials and operation of vehicles to assess the impact of replacing more internal combustion engine vehicles with electric vehicles. For this assessment, you may assume an average vehicle life of 150,000km for both vehicles. Table Q4 is a list of information that is available for your assessment. Table 24: Energy consumption and green-house gas (GHG) emissions for production of raw materials and operation of vehicles. Internal combustion Electric vehicle vehicle Production of raw materials: Energy consumption, GJ 73.2 139.2 GHG emissions, gCO2-eq./kWh 744 635 3.44 253 Operation of vehicles: Energy consumption, MJ/km GHG emissions, gCO2-eq./km Energy consumption, kWh/km GHG emissions, tonCO2- eq./GWh 0.21 10.7 i) Assess which vehicle should be considered for better sustainability based on your LCA. [10 marks) ii) In the present LCA, only production of raw materials and operation of vehicles are being considered. What would be your additional consideration in a product life cycle if a comprehensive LCA is targeted? [3 marks]
