Citroën C3 IV (2024 – Aujourd'hui)

Reliability score : 7.5/10

The 4th generation Citroën C3 (codename CC21 for emerging markets, then adapted for Europe under the 'Smart Car' platform) marks a complete break with its predecessor. It adopts a raised, small SUV-like stance, relies on very aggressive pricing (especially for the electric ë-C3), and integrates progressive hydraulic bump stop suspensions (Advanced Comfort). ⚠️ EXPERT CLARIFICATION REGARDING DIESEL: Contrary to your targeting request, there is no diesel engine available for the Citroën C3 IV (2024-2025). The Stellantis group has definitively abandoned the 1.5 BlueHDi in this segment due to anti-pollution standards (Euro 6e / Euro 7) and profitability reasons. High-mileage drivers will have to turn to the new mild-hybrid (MHEV 48V) powertrain or to competitors (Renault Clio V dCi). This repo

✅ Strengths

Definitive abandonment of the wet belt on European engines (switch to chain)
Exceptional suspension comfort for the segment (hydraulic bump stops)
Very aggressive pricing, especially for the electric ë-C3 version
Spaciousness and highly appreciated raised driving position
LFP battery on the electric model (more durable and economical)

⚠️ Weaknesses

TOTAL DISAPPEARANCE OF DIESEL: penalizing for very high-mileage motorway drivers
Basic and hard interior plastics (cost reduction)
Chaotic launch of the electric version (delivery delays due to software bugs)
Imperfect sound insulation on the motorway
Ergonomics of the 'Head-up display' (instrument cluster) which can be obscured by the steering wheel depending on position

🎯 Verdict

The Citroën C3 IV is a smart, disruptive model that democratizes access to electric and mild-hybrid technology. For buyers looking for a diesel: you must mourn the loss of this engine from Citroën. The best internal alternative is the 1.2 Hybrid 100 (MHEV), which offers very low urban consumption, or competitors (Clio dCi, Sandero LPG). Mechanically, the switch to a timing chain on petrol engines is excellent news that should restore confidence lost with the old PureTech. However, the model's newness (and launch software bugs) calls for some caution: prioritize a purchase with an extended warranty to iron out the kinks of this new 'Smart Car' platform.
