The BMW P92B36 is a 3,598 cc, twin-turbocharged V8 petrol engine produced from 2022 onwards. It features double overhead camshafts (DOHC), Valvetronic variable valve lift, and High Precision Injection direct fuel delivery, delivering high-performance dynamics and refinement. In standard tune it produces 390 kW (530 PS) with 750 Nm of torque, forming part of BMW's next-generation M performance engine family.
Fitted to models such as the G90 M5, G92 M5 Touring, and G99 XM, the P92B36 was engineered for extreme performance applications requiring track-capable power and luxury-grade smoothness. Emissions compliance is achieved through precise air-fuel control and oxygen sensing, allowing all units to meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9104).
One documented concern is potential high-pressure fuel pump wear, highlighted in BMW Service Information Bulletin 13 09 07. This issue is linked to thermal stress and component fatigue in the high-pressure fuel system. In 2024, BMW introduced a revised pump calibration and updated cooling routing to improve durability, marking a key update within the engine's production run.
All production years (2022–present) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/9104).
The BMW P92B36 is a 3,598 cc twin-turbo V8 petrol engine engineered for high-performance M models (2022–present). It combines direct fuel injection with Valvetronic variable valve lift and twin-scroll turbocharging to deliver responsive low-end torque and linear power delivery. Designed to meet Euro 6d emissions standards, it balances aggressive performance with drivability.

The twin-turbo V8 setup provides immense low-RPM torque ideal for performance driving but requires strict adherence to 15,000 km oil change intervals to prevent high-pressure fuel pump and turbo bearing wear. BMW Longlife-04 (5W-30) oil is essential due to its thermal stability and protection of direct injection components. Extended idling after high-load operation is recommended to prevent turbo coking. The high-pressure fuel pump is sensitive to heat; use of OEM-specified coolant and timely replacements per SIB 13 09 07 minimizes failure risk. Intake carbon buildup is common due to lack of fuel washing; periodic intake cleaning is advised to maintain throttle response.
Oil Specs: Requires BMW Longlife-04 (5W-30) specification (BMW Service Manual 11 50 7 842 323). Supersedes ACEA C3 requirements.
Emissions: Euro 6d certification applies to all P92B36 models (VCA Type Approval #VCA/EMS/9104).
Power Ratings: Measured under SAE J1349 standards. 390 kW output requires 98 RON fuel (BMW TIS Doc. A25113).

The BMW P92B36 was used across BMW's G9x platforms with longitudinal mounting. This engine received platform-specific adaptations-shortened intake manifolds in the G99 and revised cooling routing in the G92-and from 2024 the facelifted G90 LCI models adopted updated Valvetronic calibration, creating minor software differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the exhaust manifold (BMW TIS A25100). The 7th VIN digit indicates engine family ('M' for Bx8 series). Pre-2024 models have silver valve covers with green gasket seals; post-2024 units use black valve covers. Critical differentiation from S68: Original P92B36 has Bosch MSB9.5 ECU with 120-pin connector, while S68 uses MSB9.4 with 100-pin. Service parts require production date verification—high-pressure fuel pumps before 09/2023 are incompatible with later revisions due to internal redesign (BMW SIB 13 09 07).
The P92B36's primary reliability risk is high-pressure fuel pump wear, with elevated incidence in high-load driving with frequent short trips. Internal BMW quality reports from 2023 indicated a significant share of pre-2024 engines required pump replacement before 80,000 km, while UK DVSA records show fuel system faults contributing to emissions-related MOT failures. Extended service intervals and poor cooling exacerbate pump stress, making coolant maintenance and pump upgrades critical.
