1. BMW i8 Roadster
Following the start of production of the i8 Coupe in 2011, BMW revealed the i8 Concept Spyder in 2012. Although this topless version of the plug-in hybrid sports car was never intended to become a production reality, the BMW team re‑engineered the carbon-fibre reinforced plastic “Life” module to work without a hardtop and voila, the roadster was born. The i8 Roadster benefits from a more powerful battery that gives it a longer electric range and better fuel economy than the i8 Coupe. At the same time, the combined might of a turbocharged engine and an electric motor takes the car from 0 to 100km/h in just 4.6sec.
