10. BMW i3 (2013)
The 2013 BMW i3 introduced carbon-fiber-reinforced plastic (CFRP) in its passenger cell, reducing weight by approximately 50% compared to steel. This innovation enhanced efficiency and performance, setting a precedent for sustainable vehicle design. Additionally, the i3’s use of recycled and renewable materials, such as kenaf plant fibers and eucalyptus wood, underscored BMW’s commitment to eco-friendly manufacturing. Despite its limited sales impact, the i3’s design principles have influenced the automotive industry’s approach to sustainability. [Source: BMW i3 Design]
