18. BMW i8
The BMW i8, produced from 2014 to 2020, was a plug-in hybrid sports car that combined a 1.5-liter three-cylinder turbocharged engine with an electric motor, delivering a total output of 362 horsepower. (en.wikipedia.org) Its carbon-fiber-reinforced plastic (CFRP) passenger cell and lightweight aluminum chassis contributed to its dynamic performance. (en.wikipedia.org) Despite its striking design and advanced technology, the i8’s complex hybrid system and high price point limited its appeal to a broader audience. (en.wikipedia.org)
