Fiat 500 mild-hybrid receives mixed expert reviews

The Fiat 500 mild-hybrid model, launched in the UK in summer 2026, has received a New Car Expert Rating of D with a score of 54%. Built on the underpinnings of the 500 Electric, the model follows the retirement of previous petrol-powered ranges in 2025.

Reviewers have noted the vehicle's stylish design and agile urban driving experience, with some praising its charisma and timeless aesthetic. However, the mild-hybrid powertrain has faced criticism for being underpowered, particularly on faster roads due to the lack of a turbocharger or significant electrical assistance.

While the car's rating is impacted by its engine performance and basic warranty coverage, its overall score is supported by low predicted running costs. Competitors such as the Kia Picanto, Hyundai i10, and Toyota Aygo X are noted as offering more rounded packages.
