Smart Forfour W453 (2014 – 2019)

Reliability score : 7.8/10

The second-generation Smart Forfour (W453) marks a major turning point for the brand. Developed in close partnership with Renault (it is the technical twin of the Twingo III), it abandons the architecture of the first Forfour (based on the Mitsubishi Colt) to adopt a rear-engine, rear-wheel-drive configuration. This technical choice gives it an exceptional turning radius, ideal for urban use. Available exclusively as a 5-door, it offers decent roominess for its ultra-compact size (3.49 m). In 2019, Smart facelifted the model and abandoned combustion engines to go 100% electric (EQ models), marking the end of production for the gasoline versions covered here. Overall, it is an endearing, highly maneuverable city car, but its firm comfort and small trunk limit its versatility.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The Smart Forfour (W453) is a purebred city car that excels in its natural environment: the city. Its rear-engine architecture gives it unparalleled maneuverability. In terms of reliability, the assessment is very positive. The alliance with Renault has allowed the integration of proven engines (SCe and TCe) that do not suffer from major flaws, unlike some competitors (no problematic wet belt here, the engines are chain-driven). Buying advice: Favor the 1.0 71 hp engine if you never leave the city; it is the most reliable and the smoothest. If you regularly use expressways, the 0.9 Turbo 90 hp is essential, but check the maintenance history (water pump). In all cases, the Twinamic automatic gearbox is highly recommended for urban driving pleasure, provided it has been well maintained and updated.
