Honda Jazz IV (GR) (2020 – 2025)

Reliability score : 9.4/10

The fourth-generation Honda Jazz (code name GR/GS, sold as Fit in some markets) marks a major turning point for the model in Europe, where it is only offered as an e:HEV hybrid version. True to its DNA, it retains record-breaking interior space for its size (3.99 m) thanks to its central fuel tank and its famous "Magic Seats". The i-MMD hybrid system (renamed e:HEV) is an engineering marvel: it primarily functions as a series hybrid (the internal combustion engine acts as a generator) and only connects directly to the wheels at cruising speed via a lock-up clutch, thus doing without a traditional gearbox. An adventurous "Crosstar" version completes the range. In 2023, a facelift brought a power increase (from 109 to 122 hp) and an Advance Sport trim with specific suspension settings. It is

✅ Strengths

Exceptional overall reliability (mechanical and electronic)
Extremely low real-world fuel consumption in city and on road
Giant interior space for a car under 4 meters
Unbeatable modularity (Magic Seats rear bench)
Excellent peripheral visibility (slimmer A-pillars)
Smooth driving in urban environments

⚠️ Weaknesses

Internal combustion engine 'revving' effect during strong accelerations (hills, overtakes)
Very high purchase price new and used
Infotainment system a bit dated compared to European competitors
Highway sound insulation could be improved
Slightly reduced boot volume compared to the previous generation (due to the hybrid battery)

🎯 Verdict

The Honda Jazz IV (GR) is undoubtedly the most rational and reliable city car of its generation. Its e:HEV hybrid system is a model of efficiency in urban and suburban environments, offering astonishing real-world fuel consumption. If one accepts its minivan-like design and the noise of its engine during strong accelerations, it's a 'zero hassle' purchase. On the used car market, its value is strong, but this initial investment is largely offset by negligible running and maintenance costs, as well as an almost total absence of major breakdowns.
