The Jaguar FMBB is a 1,997 cc, inline-four turbocharged petrol engine produced between 2018 and 2023. It forms part of Jaguar Land Rover's Ingenium engine family, featuring dual overhead camshafts (DOHC), variable valve timing (VVT), and direct fuel injection with multi-hole injectors. In standard tune, it delivers 184 kW (250 PS) and 365 Nm of torque, providing strong mid-range responsiveness ideal for compact and mid-size luxury vehicles.
Fitted to key models including the E-PACE, XE (X761), and XF (X260), the FMBB engine was engineered for agile driving dynamics with a balance of performance and fuel efficiency. Emissions compliance was achieved through a close-coupled catalytic converter, gasoline particulate filter (GPF), and advanced lambda control, enabling Euro 6d-TEMP certification across its production run.
One documented concern is premature wear of the high-pressure fuel pump, highlighted in Jaguar Technical Service Bulletin JTSB-17-25-09. This issue is linked to fuel quality sensitivity and extended service intervals. From 2020, revised pump calibration and updated fuel filter design were implemented to improve durability and reduce rail pressure fluctuations.
Jaguar
Production years 2018–2023 meet Euro 6d-TEMP emissions standards (VCA UK Type Approval #VCA/EMS/7890).
The Jaguar FMBB is a 1,997 cc inline-four turbocharged petrol engine developed for compact and mid-size luxury platforms (2018–2023). It integrates direct fuel injection with twin-scroll turbocharging to deliver responsive power delivery and improved throttle response. Designed to meet Euro 6d-TEMP standards, it balances performance with emissions compliance through integrated aftertreatment systems.

The turbocharged inline-four delivers strong low-end torque ideal for urban driving but requires adherence to 15,000 km oil change intervals to maintain timing chain and high-pressure fuel pump longevity. Jaguar-approved 5W-30 oil meeting WSS-M2C947-B1 specification is critical for maintaining hydraulic lifter and chain tensioner performance. Extended idling or short-trip driving may accelerate carbon buildup on intake valves due to lack of port cleaning effect. The Bosch HDEV6 fuel pump is sensitive to low-octane fuel and contaminated petrol, necessitating use of premium unleaded (RON 95+) and periodic fuel system inspection. Post-2020 models feature updated pump firmware and filter design per Jaguar SIB JTSB-17-25-09.
Oil Specs: Requires Jaguar WSS-M2C947-B1 (5W-30) specification (Jaguar SIB JTSB-15-24-06). Supersedes ACEA C2/C3.
Emissions: Euro 6d-TEMP certification applies to all FMBB models (2018–2023) (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under SAE J1349 standards. Full output requires RON 95+ fuel (Jaguar PTS-6145).

The Jaguar FMBB was used across Jaguar's X761/X260 platforms with transverse mounting and shared architecture with Land Rover for select applications. This engine received platform-specific adaptations-shortened accessory drive in the E-PACE and revised exhaust manifolds in the XF-and from 2020 the facelifted XE adopted updated fuel calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front timing cover near the oil filler neck (Jaguar TIS A20020). The 8th VIN digit indicates engine type ('G' for 2.0L turbo petrol). Pre-2020 models have silver valve covers with black intake manifolds; post-2020 units use dark grey valve covers. Critical differentiation from diesel variants: FMBB has no GPF housing on intake and uses a twin-scroll turbocharger. Service parts require model year verification—fuel pumps for pre-2020 models are incompatible with post-update units due to calibration changes (Jaguar SIB JTSB-17-25-09).
The FMBB's primary reliability risk is high-pressure fuel pump degradation, with elevated incidence in urban driving cycles. Jaguar internal field reports from 2021 indicated a measurable number of pre-2020 units requiring pump replacement before 100,000 km, while UK DVSA MOT data shows increased emissions-related failures linked to fuel trim faults. Short-trip usage and poor fuel quality amplify pump stress, making fuel specification and service adherence critical.
