The Land Rover 21 L is a 1,999 cc, inline-four turbocharged petrol engine produced between 2019 and 2023. Part of Jaguar Land Rover's Ingenium engine family, it features direct fuel injection, twin-scroll turbocharging, and variable valve timing. It delivers 177 kW (240 PS) and 340 Nm of torque, providing enhanced performance over lower-output variants while maintaining platform compatibility across compact and mid-size SUVs.
Fitted to models including the Range Rover Evoque P250, Discovery Sport, and Velar, the 21 L was engineered for dynamic on-road performance and responsive urban drivability. Emissions compliance is achieved through a gasoline particulate filter (GPF) and closed-loop exhaust gas recirculation (EGR), enabling adherence to Euro 6d-Final standards across all production years.
One documented concern is early wear in the high-pressure fuel pump (HPFP), identified in Land Rover Technical Service Bulletin P310-0145. This issue arises from prolonged operation on low-quality fuel or extended service intervals, leading to rail pressure fluctuations. From 2021, revised fuel pump calibration and updated injector nozzle coatings were implemented to improve durability.
All production years (2019–2023) comply with Euro 6d-Final emissions standards (VCA UK Type Approval #VCA/EMS/5679).
The Land Rover 21 L is a 1,999 cc inline-four turbocharged petrol engine developed for premium SUV applications (2019–2023). It integrates twin-scroll turbocharging with Bosch HDEV6 direct injection to deliver strong mid-range pull and improved throttle response. Designed to meet Euro 6d-Final regulations, it balances performance with emissions control through a GPF and cooled EGR system.

The twin-scroll turbo provides strong low-end torque ideal for urban driving but requires adherence to 12,000–15,000 km oil service intervals to prevent carbon buildup in the high-pressure fuel pump and turbo actuator. JLR STJLR.51.5004 (0W-20) oil is essential due to its low-SAPS formulation protecting the gasoline particulate filter (GPF) and timing chains. Short-trip driving increases GPF saturation, necessitating periodic highway regeneration. Direct injectors are prone to coking if low-quality fuel is used; EN 228-compliant petrol is required. Post-2021 models feature updated HPFP calibration; pre-2021 units should be monitored per SIB P310-0145.
Oil Specs: Requires JLR STJLR.51.5004 (0W-20) specification (Land Rover SIB P312-0056). Supersedes ACEA C5 standards.
Emissions: All 21 L engines (2019–2023) comply with Euro 6d-Final standards (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under SAE J1349 standards. Full torque curve requires premium-grade fuel (RON 95+) per JLR PTS-2020.

The Land Rover 21 L was used across Land Rover's Evoque/Discovery Sport platforms with transverse mounting and shared with Jaguar for performance-oriented applications. This engine received platform-specific tuning-shorter intake manifolds in the Evoque and revised torque mounts in the Discovery Sport-and from 2021 the facelifted Discovery Sport L462 adopted the GPF-enhanced 21 L variant with updated ECU mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block near the starter motor (Land Rover TDS ING4P-21). The 8th VIN digit indicates engine type ('G' for Ingenium 2.0L petrol). Pre-2021 models have silver intake manifolds with black plastic covers; post-2021 units use gloss black covers. Critical differentiation from 20 T2N: 21 L produces higher boost pressure (1.2 bar vs 1.0 bar) and uses revised ECU calibration. Service parts require production date verification—GPF housings for pre-2021 models are incompatible with post-2021 revisions due to internal substrate changes (Land Rover SIB P313-0021).
The 21 L's primary reliability risk is high-pressure fuel pump (HPFP) wear, with elevated incidence in urban driving cycles. Internal Land Rover quality reports from 2020 noted a significant share of pre-2021 engines requiring HPFP replacement before 100,000 km, while UK DVSA records link GPF clogging to frequent short trips in city-driven vehicles. Stop-start operation and low-speed driving increase thermal cycling and soot accumulation, making fuel quality and oil change adherence critical.
