The Land Rover 25 K4F is a 1,999 cc, inline — four turbocharged petrol engine produced between 2020 and 2023. Part of Jaguar Land Rover's Ingenium engine family, it features direct fuel injection, twin — scroll turbocharging, and variable valve timing. In high — output tune it delivers 183 kW (250 PS) and 365 Nm of torque, positioning it as the performance — oriented petrol option across Land Rover’s compact and mid — size SUVs.
Fitted to models including the Range Rover Evoque…
All production years (2020–2023) comply with Euro 6d-Final emissions standards (VCA UK Type Approval #VCA/EMS/5681).
The Land Rover 25 K4F is a 1,999 cc inline-four turbocharged petrol engine developed for performance-focused SUV applications (2020–2023). 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 Land Rover 25 K4F 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 2022 the facelifted Velar adopted the GPF-enhanced 25 K4F variant with updated ECU mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 25 K4F's primary reliability risk is intake valve carbon buildup, with elevated incidence in urban driving cycles. Internal Land Rover quality reports from 2021 noted a significant share of pre-2022 engines requiring intake cleaning before 80,000 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 driving pattern and maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 25 K4F offers strong performance and responsiveness, but pre-2022 models have known intake valve coking issues in urban environments. Later revisions (2022+) show improved reliability with updated ECU calibration for carbon management. When maintained properly—using correct oil (0W-20 JLR STJLR.51.5004) and adhering to service intervals—these engines can reliably exceed 150,000 km.
Primary issues include intake valve carbon buildup from short trips, GPF clogging, turbo wastegate actuator sticking, and early timing chain tensioner wear. These are documented in Land Rover service bulletins P310-0146 and P312-0056. Regular highway driving and using quality petrol significantly reduce failure risk.
The 25 K4F is used in the Range Rover Evoque (L551), Discovery Sport (L550), Velar (L560), and E-Pace. It also appears in the Jaguar XEL and E-Pace. All models from 2020–2023 with the P300 petrol designation use this engine. All units comply with Euro 6d-Final emissions standards.
Yes. The 25 K4F responds well to ECU remapping, with stage 1 tunes typically adding +35–45 kW. Stock internals support moderate increases, but supporting mods (intercooler, exhaust) are recommended for higher outputs. Tuning must preserve GPF functionality to remain road-legal in the UK.
In real-world conditions, expect 9.5–10.5 L/100km (27–30 mpg UK) in urban driving and 7.5–8.2 L/100km (34–38 mpg UK) on highways. Combined consumption is approximately 8.5 L/100km (33 mpg UK). GPF regeneration cycles may temporarily reduce efficiency.
Yes. The 25 K4F is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic internal damage. Chain maintenance and timely oil changes are essential to prevent tensioner failure and ensure long-term reliability.
Land Rover specifies 0W-20 synthetic oil meeting STJLR.51.5004 standard. This low-SAPS formulation protects the GPF and ensures proper lubrication of the twin-chain timing system. Oil must be changed every 12,000–15,000 km or annually to maintain engine health.
