The Range Rover Sport P440e uses the AJ300 — a 3.0-litre turbocharged inline-six petrol engine with plug-in hybrid electric assistance. Fitted to the current-generation L461 from 2022 onward, the AJ300 combines a conventional petrol engine with an electric motor integrated into the gearbox, delivering a balance of performance and efficiency unique to the P440e badge. The PHEV system adds complexity beyond a standard petrol engine — we confirm your exact engine and hybrid specification by registration before any work begins, so you're quoted on the correct setup from the start. Range Rover Sport P440e Engine Compatibility The L461-generation P440e uses the AJ300 PHEV powertrain — a specific configuration combining the 3.0-litre Ingenium petrol engine with an integrated electric motor and battery system. Unlike the non-hybrid P400 or the V8-powered P530/P635, the P440e's hybrid system affects how the engine is serviced, which components are checked, and what's replaced during a rebuild. Before we quote or supply anything, we confirm: Your exact engine code (AJ300) Your generation (L461) PHEV system specification Any electronics or ECU considerations specific to your exact build This is why we always start with your registration rather than a generic quote — it protects you from paying for work that doesn't match your actual vehicle's hybrid configuration.
