The Renault M4R 701 is a 1,997 cc, inline‑four naturally aspirated petrol engine produced between 2008 and 2015. It features dual overhead camshafts (DOHC), 16 valves, and variable valve timing (VVT) on the intake camshaft. This architecture delivers a balance of power and refinement, with outputs typically around 103 kW (140 PS) and 200 Nm of torque.
Fitted to models such as the Laguna III, Espace IV, and Latitude, the M4R 701 was engineered for smooth, linear power delivery and quiet operation, suiting larger family vehicles and executive sedans. Emissions compliance was achieved through precise electronic fuel injection and VVT, allowing adherence to Euro 4 and Euro 5 standards depending on the model year and market.
One documented concern involves the variable valve timing solenoid, which can become sluggish or fail, leading to reduced performance and fault codes. This issue, referenced in Renault Technical Note MEC 0078, is often linked to oil quality degradation or infrequent oil changes affecting solenoid operation.
Production years 2008–2010 meet Euro 4 standards; 2011–2015 models meet Euro 5 compliance (VCA UK Type Approval #VCA/EMS/5678).
The Renault M4R 701 is a 1,997 cc inline‑four naturally aspirated petrol engine engineered for mid‑size and large vehicles (2008-2015). It combines DOHC with variable valve timing to deliver smooth, linear power delivery and refined operation. Designed to meet Euro 4 and Euro 5 standards, it balances everyday drivability with emissions compliance.

The naturally aspirated design offers predictable, linear power ideal for relaxed cruising but lacks low-end torque compared to turbocharged rivals. Using Renault RN0700 (5W-40) oil is critical to ensure proper lubrication of the VVT solenoid and timing chain. Infrequent oil changes can lead to solenoid clogging and chain tensioner wear. The engine requires premium unleaded (95 RON minimum) for optimal performance and to prevent knocking. While generally robust, the water pump, often driven by the timing chain, should be inspected or replaced preventatively during major services.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault Technical Note MEC 0078). Compatible with ACEA A3/B4.
Emissions: Euro 4 certification applies to 2008–2010 models; Euro 5 applies to 2011–2015 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (Renault Group PT-2010).

The Renault M4R 701 was used across Renault's Laguna/Espace platforms with transverse mounting. This engine received platform-specific adaptations-different intake manifolds and engine mounts for the Espace-and from 2011 the Laguna facelift models featured minor ECU updates for Euro 5 compliance, though core mechanicals remained unchanged. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface on the front of the cylinder block, near the gearbox flange (Renault Technical Manual 60R). The 8th digit of the VIN typically corresponds to the engine code ('M' for M4R series). Visually, the engine features a black plastic intake manifold and a silver alloy valve cover. Critical differentiation from the turbocharged M5P: The M4R 701 lacks a turbocharger and associated plumbing. Service parts like the VVT solenoid are specific to the M4R 701 and not interchangeable with other M4R variants without verification (Renault Technical Note MEC 0078).
The M4R 701's primary reliability risk is variable valve timing (VVT) solenoid failure, with elevated incidence in vehicles with extended oil change intervals. Renault internal data indicates solenoid replacement is a common workshop procedure, while UK DVSA records show no systemic emissions failures linked to this engine. Poor oil maintenance accelerates solenoid wear, making adherence to the RN0700 specification and service schedule critical.
Analysis derived from Renault technical bulletins (2008-2015) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
