This report endeavours to predict the future of automotive materials consumption to 2020. It concludes that, while steel will remain the dominant material, aluminium and plastics are expected to win more vehicle body exterior applications. It also concludes that alternatives to the steel intensive vehicle and conventional powertrain are unlikely to make a significant impact until 2020, but if they do emerge then they will demonstrate substantially different material composition.
All steps and assumptions in the calculation methodology are shown clearly, making the figures reached fully transparent and easy to adjust should different assumptions be made.
