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 delive…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M4R 701 is generally a robust and reliable engine when properly maintained. Its main Achilles' heel is the VVT solenoid, which is prone to failure with poor oil quality or infrequent changes. Addressing this and adhering to service schedules, particularly for the timing chain and water pump, allows for excellent long-term durability.
The most frequent issues are VVT solenoid failure, timing chain tensioner wear, and water pump failure. Intake manifold runner problems are less common but documented. These are well-covered in Renault service documentation and are typically straightforward, if sometimes costly, repairs.
The M4R 701 was primarily used in the Renault Laguna III (2008-2015), Espace IV (2008-2012), and Latitude (2010-2015). It was the standard 2.0L petrol engine for these larger Renault models during its production run, replacing the older F4R engine.
Yes, but gains are modest due to its naturally aspirated design. ECU remaps can yield 8-12 kW extra by optimizing ignition and fuel maps. More significant power increases require forced induction (turbo/supercharger kits), which is complex and expensive. Bolt-on modifications like intake/exhaust offer minimal gains.
Fuel economy is average for its class and era. Expect around 9.5 L/100km (30 mpg UK) in city driving and 6.5 L/100km (43 mpg UK) on the highway in a Laguna. Combined figures typically range from 35-38 mpg UK, heavily dependent on driving style and vehicle weight.
Yes. The M4R 701 is an interference engine. If the timing chain fails or jumps significantly, the pistons will collide with the open valves, causing severe internal engine damage. This underscores the importance of preventative maintenance on the timing components.
Renault mandates the use of RN0700 specification oil, typically a 5W-40 synthetic. Using the correct oil is paramount for the health of the VVT system and timing chain. Always change the oil and filter at the recommended intervals (typically 15,000 km or annually) to prevent sludge and solenoid issues.
