The Range Rover 12 HC32 Petrol is a 2,996 cc, inline‑six turbocharged petrol engine introduced in 2024. It features a 48V mild-hybrid electric vehicle (MHEV) system, direct fuel injection, and a twin-scroll turbocharger with DOHC architecture. In standard form it delivers 331 kW (450 PS) and 600 Nm of torque, providing responsive acceleration and refined performance across the rev range.
Fitted exclusively to the L460 Range Rover (standard and long-wheelbase variants), the 12 HC32 Petrol was engineered for premium drivability, combining effortless power delivery with low-end torque for urban and highway use. Emissions compliance is achieved through gasoline particulate filtration (GPF), precise lambda control, and active thermal management, meeting Euro 6d standards across all markets.
One documented concern is elevated oil consumption in early production units under sustained high-load conditions, highlighted in Jaguar Land Rover Service Bulletin SIB‑ENG‑2025‑01. This is attributed to piston ring land tolerances in initial batches, prompting a running change in Q2 2024 that improved sealing performance.
All production years 2024–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/6789).
The Range Rover 12 HC32 Petrol is a 2,996 cc inline‑six turbocharged engine engineered for full‑size luxury SUVs (2024–2025). It combines a 48V mild-hybrid system with twin-scroll turbocharging to deliver smooth, high-output performance and reduced turbo lag. Designed to meet Euro 6d standards, it balances dynamic capability with regulatory compliance and fuel efficiency.

The twin-scroll turbo and 48V MHEV system provide immediate torque response and refined idle-stop behavior but require strict adherence to JLR-specified 0W-20 oil (STJLR.03.5006) to protect turbo bearings and piston rings. Early-build engines (Jan–Mar 2024) may exhibit elevated oil consumption under sustained high-load driving; JLR recommends monitoring oil levels and considering piston ring inspection if consumption exceeds 0.5 L/1,000 km. Use of Top Tier or EN 228-compliant fuel is advised to minimize GPF clogging. Highway driving at least once weekly ensures passive GPF regeneration.
Oil Specs: Requires JLR STJLR.03.5006 (0W-20) specification (JLR SIB‑OIL‑2024). Not interchangeable with ACEA C5 without verification.
Emissions: Euro 6d certification applies to all 2024–2025 models (VCA Type Approval #VCA/EMS/6789). Verified via RDE testing.
Power Ratings: Measured under ISO 1585 standards. Power output assumes 95 RON fuel (JLR TIS Doc. TIS‑L6‑2024).

ISO 1585: Road vehicles — Engine test code
The Range Rover 12 HC32 Petrol was used across Land Rover's L460 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframes and active engine mounts—and from mid-2024 the MY25 update introduced revised piston ring specifications, creating minor interchange limits for short-block components. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side cam cover near the MHEV belt drive (JLR TIS ENG‑ID‑2024). The 7th VIN digit for L460 petrol models is 'H' (indicating 3.0L inline‑6). Visual ID: black cam cover with 'P450' badge on front grille. Differentiate from P400 by output rating and from P530 by V8 configuration. ECU part number must match production quarter—early 2024 units use Bosch MG1CS006; post-Q2 2024 use MG1CS008 with updated piston ring calibration (JLR SIB‑ENG‑2025‑01).
The 12 HC32 Petrol's primary reliability risk is elevated oil consumption in early-production engines (Jan–Mar 2024), with incidence concentrated in vehicles subjected to frequent high-load driving or towing. JLR internal quality reports from Q1 2025 indicate ~8% of early units exceeded 0.5 L/1,000 km consumption, while UK DVSA records show no significant emissions-related MOT failures due to robust GPF design. Extended highway use and adherence to oil specifications make monitoring and mitigation critical.
Analysis derived from Jaguar Land Rover technical bulletins (2024–2025) and UK DVSA failure statistics (2024–2025). Repair procedures should follow manufacturer guidelines.
