Fiat will begin production of the new 500 Hybrid in November – and the first official pictures reveal it has received an overhauled interior and a six-speed manual gearbox.

More than 100,000 examples of the new model are expected to roll off production lines each year at the company's Mirafiori plant in Turin. Both hatchback and cabrio models will be sold.

The first images of non-camouflaged pre-production models show that it will look identical to the electric 500e except for a reworked front grille to feed more air to a petrol engine.

That engine will be the same 1.0-litre three-cylinder mild-hybrid Firefly engine that powers the old 500 and Fiat Panda.

The new Fiat adopts the 500e's interior, which includes Stellantis's 10.25in touchscreen. Alongside this, the dashboard features a larger and squarer new storage cubby and the gearlever is elevated alongside the steering wheel – as in the old petrol 500.

The move to retrofit an electric car with a combustion engine is unprecedented in the European car industry. 

Several reports in March 2024 suggested that the bold measure was borne out of two key challenges. 

First was the need to up production rates at the Mirafiori factory amid slow sales of the 500e and its Abarth 500e hot hatch sibling, which led Fiat to pause production on several occasions last year.

Meanwhile, it ended production of the old petrol 500 (which accounted for the majority of 500 sales), as the 17-year-old model fell foul of new EU legislation on cybersecurity, which would have required a costly rehomologation effort.

Fiat CEO Olivier François acknowledged the challenges, saying in a statement that the 500 Hybrid will boost production at Mirafiori "to ensure the plant’s productivity".

He added that launching a new combustion-engined 500 in response to flagging sales of the EV serves as "proof that social relevance is at the core of the brand mission".

Fiat previously said it would also invest €100 million (£85m) into the 500e, with plans to redesign its platform for new battery technologies aimed at improving its affordability.

This suggests that an update for the EV is also due around 2026.
