7. BMW i3
Launched in 2013, the BMW i3 was the first mass-produced electric car to feature a carbon fiber-reinforced plastic (CFRP) passenger cell, significantly reducing weight while maintaining structural integrity. Its fully electric powertrain and use of sustainable materials, such as recycled plastics and natural fibers, showcased a commitment to eco-friendly innovation. However, its unconventional design and premium pricing presented challenges in appealing to mainstream consumers. (en.wikipedia.org)
