For the Fiat 500 Hybrid, Fiat relies on a completely new three-cylinder gasoline engine with a belt starter generator that works in the 12 volt electrical system and is combined with a compact lithium-ion battery. 51 kW (70 hp) are made available from one liter of displacement. The engine runs much smoother than the high-speed 2-cylinder models and meets the Euro 6d emission class. The automatic start-stop system is less vibration than the four-cylinder gasoline engine.
