Multiple ways to lighten a vehicle using aluminum Weight reduction has now gained its place in the design or redesign process of ground transportation vehicles. Based on the application of the vehicle, different approaches can be used to reduce the weight where an optimization of the design can be combined with the use of lighter materials. In cases where steel has been the base material for many years, the selection of replacement materials implies adding new parameters that must be considered at the early design stages of a vehicle. This article intends to show, using real life examples, how aluminum was successfully integrated into vehicles, with an outstanding collaboration of experts from universities. *Y.
