The Genesis Tau 5.0 is a 5,038 cc, V8 naturally aspirated petrol engine produced between 2016 and 2020. It features dual overhead camshafts (DOHC), 32 valves, and continuously variable valve timing on both intake and exhaust. This engine delivers 313 kW (425 PS) and 520 Nm of torque, offering a linear, high — revving powerband characteristic of large — displacement naturally aspirated engines.

The Genesis Tau 5.0 is a 5,038 cc V8 naturally aspirated petrol engineered for flagship luxury sedans (2016-2020). It combines a dual overhead camshaft design with continuously variable valve timing to deliver smooth, linear power and a refined driving experience. Designed to meet Euro 6 standards, it prioritizes acoustic refinement and effortless performance over ultimate efficiency.

The Genesis Tau 5.0 was used exclusively in Genesis's G90 platform with longitudinal mounting. This engine received no significant platform-specific adaptations during its production run. All applications 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.
The Tau 5.0's primary documented characteristic is higher-than-average oil consumption at higher mileages, inherent to its high-performance V8 design. Genesis TSB-17-EN-005 outlines this as a normal operational trait, while owner feedback confirms it typically manifests after 100,000 km. Extended oil change intervals or using incorrect oil viscosity can exacerbate consumption, making regular level checks critical.
Analysis derived from Genesis technical bulletins (2016-2020) and aggregated owner-reported data (2017-2024). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The Tau 5.0 is a robust and well-engineered V8. Its main long-term consideration is managing higher-than-average oil consumption, which is a documented characteristic rather than a defect. With proactive maintenance, including regular oil level checks and using the correct oil, it can be very reliable for 200,000 km and beyond.
The most frequently documented issues are higher-than-average oil consumption, gradual catalytic converter degradation, and occasional VVT solenoid or IMRC actuator failures. These are covered in Genesis service bulletins and are generally straightforward to address.
The Tau 5.0 engine was used exclusively in the first-generation Genesis G90 luxury sedan (model years 2016 to 2020), specifically in the flagship 5.0 V8 trim level. It was not used in the G70, G80, or GV series SUVs.
Aftermarket ECU tuning is common on the TAU-5-0 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.
Official combined figures are around 12.5 L/100km. Real-world consumption typically ranges from 10.5 L/100km on highways to 16-18 L/100km in city driving. Its large displacement and performance focus mean fuel economy is not its primary strength.
Yes. The Tau 5.0 is an interference engine. If the timing chain were to fail catastrophically, the pistons would collide with the open valves, causing severe internal engine damage. The chain is very durable with proper maintenance.
Genesis specifies a full synthetic 5W-30 oil meeting the latest API SP (or equivalent) standard. Using Genesis Genuine Oil or a high-quality equivalent is crucial for protecting the engine under high-RPM operation and managing oil consumption.
