The One-Liter Eco Marvel: VW XL1
In 2013, Volkswagen unveiled the XL1, a groundbreaking two-seater plug-in hybrid that achieved an astonishing fuel efficiency of 261 mpg. Its design featured a lightweight carbon fiber monocoque, a drag coefficient of just 0.189, and a low center of gravity, all contributing to its exceptional aerodynamics. Powered by a 47-horsepower two-cylinder diesel engine and a 27-horsepower electric motor, the XL1 could travel up to 31 miles on electric power alone.
