Twenty months after making that bold decision, Fiat’s efforts have borne fruit.
The conversion required the near-total redevelopment of the 500e: new subframes are located at the front and rear ends to accommodate a petrol engine and six-speed manual gearbox, and a fuel tank has been subbed in for the EV’s traction battery.
Even with the 500e’s diminutive motor removed, space under the bonnet was severely limited. The 1.2-litre Puretech petrol engine deployed in a range of Stellantis models, including the larger Fiat Grande Panda, simply wouldn’t have fit. Developing something bespoke would have been too costly.
That left the naturally aspirated 1.0-litre three-cylinder used by the previous 500 Hybrid and updated for the Italian-market Panda in 2024 as the only option. This includes a 12V starter-generator hybrid system, and puts out a total of 64bhp and 68lb ft.
Inside, there’s a revised dashboard to accommodate a gearlever, mounted high as in the previous 500.
Otherwise, the 500 Hybrid looks almost identical to the EV, with its front end only gaining a 'moustache' grille to provide sufficient cooling to the engine and its gubbins.

The Fiat 500 Hybrid range at a glance
There's only one engine and gearbox combo available – no automatic option, as that would have been too costly for Fiat to engineer – leaving you to choose from one of three trims.
Entry-level Icon brings 16in alloy wheels, LED headlights, a black cloth interior and rear parking sensors.
For a limited time, you'll also be able to opt for the Torino trim, named after Fiat's home town. This builds on Icon with special badging and cloth and vinyl upholstery.
Stepping up to the range-topping La Prima upsizes the alloys to 17in, brings faux-leather upholstery with neat 'cannelloni' stitching, and adds heating for the seats and windscreen and a reversing camera.
