Toyota GR Yaris I (2020 – 2024)

Reliability score : 8.8/10

The Toyota GR Yaris (Generation I) is a true anomaly in the modern automotive market: a 'homologation special' designed by Gazoo Racing to serve as the basis for Toyota's WRC rally car. Unlike the standard Yaris, it sits on a hybrid platform (GA-B front, GA-C rear), features a specific 3-door body with a forged carbon roof and aluminum doors and lids. Equipped with the world's most powerful 3-cylinder engine at its release and a sophisticated AWD system (GR-Four), it offers supercar performance on winding roads. Its overall reliability is exceptional for a sports car of this caliber, although it requires rigorous maintenance, particularly when used on the track.

✅ Strengths

Oversized and ultra-robust mechanical design
Dual injection (D-4S direct and indirect) preventing valve carbon buildup
Exceptional dynamic behavior and adjustable GR-Four transmission
Almost non-existent depreciation (collector's vehicle)
Build quality from the Motomachi plant (Japan)

⚠️ Weaknesses

High maintenance cost (frequent transmission fluid changes)
Overheating of the AWD system (ITCC) during intense track sessions
Driving position considered too high by some body types
Forward visibility hindered by the rearview mirror/camera block
Cabin noise (minimal soundproofing to save weight)

🎯 Verdict

The Toyota GR Yaris is a future classic and one of the most reliable sports cars of its generation. Designed without compromise, its G16E-GTS engine withstands enormous stress without flinching, provided that maintenance is followed to the letter. If you are buying a used model, favor an example with the 'Circuit Pack' (Torsen differentials) and demand a crystal-clear service book, proving that the transmission fluids have been replaced regularly. It is a highly recommended passion purchase, coupled with a safe financial investment.
