The Jaguar 8S is a 4,999 cc, V8 naturally aspirated petrol engine produced between 2010 and 2017. It was developed as a high — performance powerplant for Jaguar's luxury GT and sports car lineup, featuring dual overhead camshafts (DOHC), variable valve timing (VVT), and direct fuel injection. In standard tune, it delivered 375 kW (510 PS), with peak torque of 625 Nm, enabling strong high — RPM performance and refined cruising.
Fitted to models such as the XKR — S, XJ Superspor…

The Jaguar 8S is a 4,999 cc V8 naturally aspirated engine engineered for high-performance luxury vehicles (2010–2017). It combines direct fuel injection with variable valve timing to deliver responsive throttle characteristics and smooth power delivery. Designed to meet Euro 5 emissions standards, it balances performance with drivability in grand touring applications.

The Jaguar 8S was used across Jaguar's XK/XJ/F-Type platforms with longitudinal mounting and no licensed external usage. This engine received platform-specific adaptations-higher-flow intakes in the F-Type and reinforced engine mounts in the XJ Supersport-and from 2014 the facelifted F-Type R model adopted revised engine management software, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 8S delivers strong performance and refinement, but pre-2014 models had reliability concerns, particularly high-pressure fuel pump wear. Later revisions (post-2015) improved pump durability, so well-maintained examples can be robust. Regular servicing and using premium fuel (98 RON) greatly aid longevity.
The biggest issues are high-pressure fuel pump degradation, intake carbon buildup, coolant leaks from thermostat housing, and valve cover oil seepage. These are well-documented in Jaguar service bulletins and verified through DVSA inspection data.
The 8S engine was used in high-performance Jaguar models including the XKR-S (2012–2014), XJ Supersport (2010–2017), and F-Type V8/R (2013–2017). It was not used in any other manufacturer's vehicles.
Aftermarket ECU tuning is common on the 8S platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In an F-Type R (2015), combined consumption is ~10.5 L/100km (~27 mpg UK). City driving may exceed 14 L/100km (~20 mpg), while highway runs can achieve ~8.5 L/100km (~33 mpg). Real-world figures depend heavily on driving style.
Yes. The 8S is an interference engine. If the timing chain fails, pistons can contact open valves, causing catastrophic damage. Chain maintenance and oil quality are critical—any abnormal noise should be investigated immediately.
Jaguar specifies 5W-30 synthetic oil meeting WSS-M2C947-A1 spec. Change every 15,000 km or annually. Using correct oil ensures proper lubrication of the timing chain and protection for high-temperature engine components.
