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 spirited driving and track capability. Emissions compliance for its production period was primarily achieved through precise fuel injection, a turbocharger, and catalytic converter technology, meeting Euro 5 standards.
One documented service concern involves premature turbocharger bearing wear, which can lead to reduced boost pressure and oil consumption. This issue, referenced in Renault technical bulletin RTB-2013-08, is often linked to inadequate cooldown periods after high-load operation.
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5681).
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 turbocharged design provides strong, accessible torque but requires strict adherence to 10,000 km oil change intervals using specified 5W-40 oil to protect the turbocharger and timing chain. The turbo’s variable geometry system is sensitive to oil quality; using incorrect oil can lead to actuator sticking and boost control errors. The engine is robust under high load but requires a 1-2 minute idle cooldown after spirited driving to prevent turbo bearing coking. The timing chain is durable but should be inspected if unusual noise is detected.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Owner's Manual Supp. 2010). ACEA A3/B4 is the underlying standard.
Emissions: Euro 5 certification applies to all 2010–2018 F4Rt 811 engines (VCA Type Approval #VCA/EMS/5681).
Power Ratings: Measured under ECE R85 standards (Renault TIS Doc. F4Rt-004). Output is consistent across model applications.

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.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, below the exhaust manifold (Renault TIS F4Rt-005). The 8th digit of the VIN typically corresponds to the engine type for Renault vehicles of this era. Visually, the F4Rt engine can be identified by its black plastic intake manifold, the 'F4Rt' casting mark on the block, and the prominent Garrett turbocharger on the exhaust manifold. Differentiate from the naturally aspirated F4R by the presence of the turbo and associated plumbing. Service parts are generally consistent across Mégane III RS and Scénic III RS applications for this specific engine code.
The F4Rt 811's primary reliability risk is related to its turbocharger, particularly premature bearing wear. Renault internal service data indicates this is a frequent cause for powertrain-related workshop visits. Failure to observe cooldown periods after high-load operation or use of incorrect viscosity oil significantly increases the risk of turbo failure.
