Ford Mustang S550 (2015 – 2023)

Reliability score : 8.2/10

The sixth-generation Ford Mustang (code name S550) marks a historic turning point for the model: it is the first Mustang to be officially marketed globally (including in Europe with right- or left-hand drive) and the first to adopt independent rear suspension (IRS) as standard, abandoning the solid axle. The 2018 facelift (Phase 2) brought major improvements: a redesigned front end, 100% digital instrumentation, a 10-speed automatic gearbox (10R80), and an evolution of the 5.0L V8 (Coyote Gen 3) incorporating dual injection. It is an essential benchmark in the Pony Cars segment, offering an unbeatable price/performance/sensation ratio, particularly in the V8 version. Overall reliability rating: Good to Very Good.

🎯 Verdict

The Ford Mustang S550 is an undeniable success. It has managed to modernize its road handling thanks to its independent suspension while retaining the soul of the Pony Car. Expert's choice: Without hesitation, favor the 5.0L V8 Coyote, ideally in Phase 2 (2018+) to benefit from the Gen 3 engine (dual injection), the digital dashboard, and a slightly improved finish. If you opt for a manual gearbox, the special series (Mach 1, Bullitt) equipped with the Tremec gearbox transform the driving experience compared to the fragile base MT82. The 2.3 EcoBoost remains a good choice for economical daily use, but it requires more rigorous monitoring (turbo, warm-up time) and loses the auditory charm inherent to the model. Finally, avoid dubious imports without a clear Carfax history.
