The Renault F4Rt 811 is a 1,998 cc, inline‑four turbocharged petrol engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) design with 16 valves and variable valve timing (VVT) on the intake camshaft. This configuration delivers strong mid — range torque and high — rpm power, with outputs typically around 147 kW (200 PS) and 275 Nm.
Fitted to performance — oriented models such as the Mégane III RS and Scénic III RS, the F4Rt 811 was engineered for spi…
Production years 2010–2018 meet Euro 5 standards .
The Renault F4Rt 811 is a 1,998 cc inline‑four turbocharged petrol engine engineered for hot hatches and performance MPVs (2010-2018). It combines DOHC 16-valve architecture with variable valve timing and a turbocharger to deliver aggressive acceleration and a broad powerband. Designed to meet Euro 5 standards, it balances high performance with acceptable emissions for its class.

The Renault F4Rt 811 was used exclusively in Renault Sport's Mégane III RS and Scénic III RS platforms with transverse mounting. This engine received minor ECU calibrations for different model variants but no major mechanical revisions affecting core compatibility 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.
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 F4Rt 811 is a high-performance engine that can be reliable with meticulous maintenance. Its main weakness is the turbocharger, which requires strict adherence to cooldown procedures and oil changes. With proper care using the specified 5W-40 oil, these engines can exceed 150,000 km without major issues.
The most frequent issues are turbocharger bearing failure, VVT solenoid malfunction, high-pressure fuel pump breakdown, and oil leaks from the turbo oil lines. These are well-documented in Renault service information and require prompt attention to avoid costly damage.
The F4Rt 811 engine was used exclusively in the Renault Sport variants: the Mégane III RS (2011–2016) and the Scénic III RS (2011–2016), specifically in their 2.0 Turbo 200 models. It was not used in standard Renault models.
Yes, the F4Rt 811 has significant tuning potential. ECU remaps can yield gains of 30-50 kW by optimizing boost, ignition, and fuel maps. More significant power increases require hardware upgrades like a larger turbo, intercooler, and exhaust, but the bottom end is quite strong for moderate tuning.
Fuel economy is typical for a high-performance turbo petrol engine. Expect around 11.5 L/100km in city driving and 7.5 L/100km on the highway, resulting in a combined figure of approximately 28-32 mpg (UK). Actual consumption varies greatly with driving style.
Yes. The F4Rt 811 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. Fortunately, the chain is very durable with proper maintenance.
Renault specifies a 5W-40 synthetic oil meeting RN0700 or RN0710 standards. Using the correct oil is crucial for the health of the turbocharger, VVT system, and timing chain. Change intervals should not exceed 10,000 km or 12 months.
