The Land Rover P300 is a 1,997 cc, inline-four turbocharged petrol engine produced between 2018 and 2023. It features direct fuel injection, twin-scroll turbocharging, and an integrated exhaust manifold, delivering 221 kW (300 PS) and 400 Nm of torque. This high-specific-output engine uses a 12 V mild-hybrid system (MHEV) to enhance responsiveness and reduce fuel consumption during coasting and stop-start cycles.
Fitted to the Range Rover Evoque, Velar, and Discovery Sport models, the P300 was engineered for premium urban and highway performance with improved refinement and emissions control. Emissions compliance is achieved through a close-coupled three-way catalyst and gasoline particulate filter (GPF), enabling Euro 6d-TEMP standards across all markets during its production run.
One documented concern is premature turbocharger wastegate actuator failure, highlighted in Land Rover Technical Service Bulletin SIB-501052. The issue affects early 2018–2020 builds and is linked to carbon buildup restricting actuator movement. From 2021, revised calibration and updated actuator hardware were introduced to improve durability and boost control consistency.
Production years 2018–2023 meet Euro 6d-TEMP emissions standards (VCA UK Type Approval #VCA/EMS/P300-E6d).
The Land Rover P300 is a 1,997 cc inline-four turbocharged petrol engine engineered for compact and mid-size SUVs (2018–2023). It combines direct injection with twin-scroll turbocharging and 12 V mild-hybrid electrification to deliver strong mid-range power and improved efficiency. Designed to meet Euro 6d-TEMP standards, it balances performance with real-world emissions compliance.

The twin-scroll turbo provides strong low-RPM torque ideal for urban driving but requires strict adherence to 15,000 km oil service intervals to maintain turbo bearing and timing chain longevity. SAE 5W-30 oil meeting Land Rover TX1 specification is essential for high-temperature stability and cam lobe protection. Extended idling or short-trip operation should be minimized to prevent carbon buildup on intake valves and GPF clogging. The 12 V MHEV system demands a robust electrical supply; battery degradation can impair regenerative braking and engine-off coasting. Post-2021 models feature updated wastegate actuators; pre-2021 units should be inspected per Land Rover SIB-501052. GPFs require periodic active regeneration and should not be removed, as this disables engine management adaptations.
Oil Specs: Requires SAE 5W-30 meeting Land Rover TX1 specification (Land Rover SIB 0123/12). Equivalent to ACEA A3/B4.
Emissions: Euro 6d-TEMP certification applies to all 2018–2023 models (VCA Type Approval #VCA/EMS/P300-E6d).
Power Ratings: Measured under SAE J1349 standards. Output assumes 98 RON fuel (Land Rover TDS Doc. A32100).

The Land Rover P300 was used across Land Rover's L550/L560 platforms with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-integrated air intake routing in the L550 and revised cooling layout in the L560-and from 2020 the facelifted L550 received updated MHEV software, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine identification tag affixed to the right-side cylinder head near the intake manifold (Land Rover TDS A32100). The 8th VIN digit indicates engine type ('G' for P300). Pre-2021 models have silver intake manifolds with black valve covers; post-2021 units retain the same appearance but feature revised wastegate actuator calibration. Critical differentiation from P250 variant: P300 delivers 300 PS with higher turbo boost pressure; P250 produces 250 PS with reduced boost and no MHEV in early models. Service parts require model-year verification—wastegate actuators for 2018–2020 models are incompatible with 2021+ due to internal design changes (Land Rover SIB-501052).
The P300's primary reliability risk is turbocharger wastegate actuator failure in early models, with elevated incidence in vehicles subjected to frequent short journeys. Internal Land Rover field reports from 2020 indicated over 12% of pre-2021 units required actuator replacement before 80,000 km, while UK DVSA data shows increased GPF efficiency faults linked to low-speed operation. Urban driving and poor maintenance accelerate carbon buildup, making oil quality and service adherence critical.
