Toyota Yaris IV (XP210) (2020 – 2025)

Reliability score : 9.0/10

The fourth-generation Toyota Yaris (XP210) marks a complete break from its predecessors. Based on the new TNGA-B platform, it gains in dynamism, rigidity, and features a much more assertive design. Important clarification regarding your request: Toyota definitively abandoned diesel engines on the Yaris well before this generation. Therefore, there is no diesel engine (D-4D) on the Yaris IV, in any global market. Toyota's strategy relies exclusively on 3-cylinder gasoline engines (naturally aspirated and turbocharged) and its 4th-generation hybrid (HEV) technology. The Yaris IV has repeatedly established itself as the best-selling car in Europe, praised for its record energy efficiency and exemplary reliability. A slight restyling (facelift) and the introduction of a 130 hp hybrid version t

✅ Strengths

Exceptional real-world fuel consumption on hybrid versions
Very high overall mechanical reliability (Toyota standard)
Dynamic chassis and significantly improved driving pleasure compared to the Yaris III
Very rich standard safety equipment (Toyota Safety Sense)
Excellent resale value on the used car market

⚠️ Weaknesses

Total absence of diesel offering (for very high mileage highway drivers)
Cramped rear legroom and difficult access to rear seats
Boot volume below the category average (286 liters)
Dated and slow infotainment system on pre-facelift models (before 2024)
Highway sound insulation (wind and road noise)

🎯 Verdict

The Toyota Yaris IV is a highly recommended purchase. Although it offers no diesel engine options, its hybrid version (116 or 130 hp) largely compensates with urban and suburban fuel consumption often lower than an equivalent diesel, without the clogging problems (DPF, EGR valve) associated with short trips. It is the undisputed queen of reliability in the city car category. The only drawbacks concern its limited interior space and the fragility of its 12V battery if it is immobilized for too long. For predominantly highway use (where diesel excelled), a used Renault Clio dCi or a Peugeot 208 BlueHDi could be considered, but at the cost of significantly lower overall reliability than the Japanese car.
