Toyota Prius IV (XW50) (2015 – 2022)

Reliability score : 9.5/10

The Toyota Prius Generation IV (XW50) marks a significant milestone in the model's history, being the first vehicle built on the Toyota New Global Architecture (TNGA-C) platform. This transition drastically improved chassis rigidity, lowering the center of gravity and transforming the Prius from a mere eco-appliance into a genuinely competent handling car. Launched late 2015 (2016 model year), its highly polarizing, aggressive exterior styling was a major talking point, leading to a more conservative facelift in 2019. The XW50 generation introduced the AWD-e system (an electric motor on the rear axle for low-speed traction) and a significantly upgraded Plug-in Hybrid version known as the Prius Prime (or Prius PHV in some markets). From a reliability standpoint, the Gen 4 Prius is an absolu

✅ Strengths

Unmatched long-term reliability and durability
Exceptional fuel economy (easily 4.0 - 4.5 L/100km in real-world conditions)
TNGA platform provides surprisingly good handling and ride comfort
Low running costs (brakes last 100k+ miles due to regenerative braking)
Standard Toyota Safety Sense (TSS) on most trims/years

⚠️ Weaknesses

Highly polarizing exterior design (especially pre-2019 facelift)
Infotainment system is outdated, sluggish, and lacks Apple CarPlay/Android Auto on early models (pre-2020)
Noticeable road and wind noise at highway speeds
Rear visibility is compromised by the split-glass tailgate design
High risk of catalytic converter theft (though slightly harder to steal than Gen 2/3)

🎯 Verdict

The Generation 4 Toyota Prius (XW50) is arguably one of the safest and most rational used car purchases on the planet. By resolving the mechanical weaknesses of the previous generation and adopting the excellent TNGA chassis, Toyota created a vehicle that is not only bulletproof but also pleasant to drive. While the styling may not appeal to everyone and the infotainment is dated, its incredibly low running costs, stellar fuel economy, and legendary longevity make it an absolute must-buy for commuters and pragmatists. The PHEV (Prime) is an excellent bonus for those with home charging.
