Toyota Land Cruiser 300 (J300) (2021 – Présent)

Reliability score : 8.9/10

The Toyota Land Cruiser 300 Series (J300) marks a historic turning point for the legendary off-roader. Based on the new TNGA-F architecture (lightened and stiffened ladder frame), it definitively abandons V8 engines in favor of more efficient bi-turbo V6s, while losing approximately 200 kg. Although not officially sold in Western Europe or North America (which receives its luxurious cousin, the Lexus LX 600, and the smaller Land Cruiser 250/Prado), the J300 remains the undisputed king in the Middle East, Australia, and Africa. The 3.3-liter bi-turbo diesel engine (F33A-FTV) is particularly praised for its immense torque (700 Nm) and range, advantageously replacing the old 4.5L V8 (1VD-FTV). The overall reliability score is expected to be excellent, true to the model's reputation, although

🎯 Verdict

The Toyota Land Cruiser 300 successfully takes on the difficult challenge of modernizing an icon without betraying its DNA. The switch to the bi-turbo V6 diesel (F33A-FTV) is a major success: it offers superior towing and off-road performance compared to the old V8, while reducing fuel consumption. Although mechanical complexity is increasing (two turbos, DPF, 10-speed gearbox), Toyota's design rigor ensures top-tier reliability. Buying advice: The 3.3L V6 Diesel is the top choice for 90% of buyers (towing, expeditions, long distances). Avoid it only if you primarily drive in the city (risk of DPF clogging). In that case, or if you're looking for pure performance, the 3.4L V6 Gasoline is a formidable alternative, though thirstier.
