The F-Pace 400 Sport was launched in 2022 as a special edition, distinguished by its use of the Ingenium AJ300P — a 3.0-litre inline-six petrol engine with mild-hybrid assistance. This is the same engine family as the standard F-Pace P400, but the 400 Sport carries the badge as a separate, high-spec variant. It's part of Jaguar's newer-generation six-cylinder Ingenium range, paired with a 48V mild-hybrid system for improved responsiveness and efficiency. Jaguar F-Pace 400 Sport Engine Codes AJ300P A 3.0-litre inline-six petrol MHEV fitted to the F-Pace 400 Sport from 2022 onwards (X761). The same Ingenium 6-cylinder pattern shared with the F-Pace D300 diesel and P400 petrol variants — we service it to the same standard as our other F-Pace rebuilds, replacing timing chains, bearings and gaskets as standard.

While it shares its core architecture with other Ingenium six-cylinder engines in the F-Pace range, its ECU calibration, power output (400PS) and mild-hybrid setup are unique to the 400 Sport badge. Before we quote or supply anything, we confirm: - Your exact engine code (AJ300P) via registration or VIN - Your generation (X761) - Drivetrain and ancillary specification - Any electronics or ECU considerations specific to your exact build This is why we always start with your registration rather than a generic F-Pace quote — it protects you from paying for parts that don't fit your actual car.

We replace timing chains, bearings and gaskets as standard on every AJ300P rebuild. Do you supply used F-Pace 400 Sport engines? Yes, in some cases a matched low-mileage used engine is the right option. Our team will advise honestly once we've matched your registration and understood your situation.
