The fourth-generation Range Rover (code name L405) marked a major technological breakthrough by adopting an all-aluminum monocoque structure, allowing it to shed up to 420 kg compared to its predecessor. Positioned at the pinnacle of automotive luxury, it combines exceptional off-road capabilities with comfort worthy of the best limousines. The 2018 facelift introduced the Touch Pro Duo infotainment system and, most importantly, the P400e plug-in hybrid powertrain, designed to meet emissions standards and offer tax advantages. Although majestic, this model suffers from a highly mixed reliability reputation, particularly due to its complex electronic architecture and certain problematic engines.
The Range Rover L405 is a paradoxical vehicle: it offers an unparalleled driving experience and luxury, but demands a colossal maintenance budget and a high tolerance for breakdowns. The P400e hybrid version is attractive on paper (taxation, silence), but it superimposes the complexity of a high-voltage electrical system onto an already temperamental basic electronic architecture. If you opt for a P400e, demand a model under manufacturer warranty or with a comprehensive extended warranty covering the battery and electronics. Absolutely avoid the Diesel V6s (TDV6/SDV6) due to the risk of crankshaft failure. The 'safest' choices (all things considered) remain the Supercharged V8s (with preventive maintenance of the cooling system) or the recent Ingenium inline-6 engines.
