Arriving in 2022, the second major facelift of the Fiat 500X introduced the brand's bold '500' front grille badge, streamlined trim levels and introduced a sophisticated 48-volt mild-hybrid powertrain. Competing directly against the Renault Captur E-Tech and Ford Puma EcoBoost Hybrid, this final iteration brought refined low-speed electric cruising to the range, ensuring that modern Fiat 500X maintenance centres primarily on electrical network diagnostics and hybrid software calibration.
The sole headline powertrain is the 1.5-litre FireFly turbocharged 4-cylinder petrol engine producing 130 hp and 240 Nm of torque, paired with a 48V electric motor generating 15 kW (20 hp) integrated directly into a new 7-speed dual-clutch transmission (e-DCT). This setup permits silent electric starting, low-speed creep in stop-and-go traffic, and regenerative deceleration. However, smooth performance relies fundamentally on the state of charge and health of the 12V auxiliary battery, which energises the onboard control computers and high-voltage DC-DC converters.
