Fiat has started production of a gas-powered version of the new 500 that was initially planned to be electric-only.Full-scale production of the new 500 'Hybrid' is set to commence in November with a sales target of at least 100,000 units annually.The electric models of the Fiat 500 were not successful in the market due to high pricing, leading Fiat to reintroduce a combustion engine model.The design of the new combustion model remains similar to the electric version, with minor differences in the interior and exterior features.
