The Renault F4R 730 is a 1,998 cc, inline‑four petrol engine produced between 1996 and 2001. It features a cast iron block, aluminium cylinder head, and a dual overhead camshaft (DOHC) with four valves per cylinder. In standard form, it delivered approximately 103 kW (140 PS) and 185 Nm of torque, offering a refined and responsive driving experience for its class.
Fitted to models such as the Renault Laguna MkI and Renault Scénic, the F4R 730 was engineered for drivers seeking a balance of performance and comfort. It offered improved high-RPM power delivery and better fuel efficiency compared to the older F3R series. Emissions compliance for its production period was managed through advanced engine management and exhaust systems, meeting Euro 2 standards.
One documented concern is premature failure of the exhaust manifold studs, which can lead to exhaust leaks. This issue, referenced in Renault Service Bulletin SB 98-045, is often attributed to thermal cycling and material fatigue. The engine was succeeded by the updated F4R 732 variant, which featured minor ECU and emissions refinements.
Production years 1996–2001 meet Euro 2 emissions standards as per European Commission Directive 94/12/EC.
The Renault F4R 730 is a 1,998 cc inline‑four petrol engine engineered for mid‑size hatchbacks and MPVs (1996-2001). It combines a DOHC 16-valve valvetrain with multi-point fuel injection to deliver improved performance and efficiency. Designed to meet Euro 2 emissions regulations, it represents a significant evolution from the earlier SOHC F3R engines.

The DOHC 16-valve design provides a broader, more responsive power band compared to SOHC engines, making it more engaging to drive. Strict adherence to the 60,000 km timing belt replacement interval is critical to prevent failure. Using the specified 10W-40 oil ensures proper lubrication. The engine's known weakness is the exhaust manifold; inspecting for stud breakage or leaks during routine service is advisable. The non-interference design prevents catastrophic damage if the timing belt fails.
Oil Specs: Requires SAE 10W-40 mineral or semi-synthetic oil (Renault Owner's Manual). ACEA A3 specification is suitable.
Emissions: Compliance with Euro 2 applies to all production years (European Commission Directive 94/12/EC).
Power Ratings: Measured under EEC 80/1269 standards (European Commission Directive 80/1269/EEC).

The Renault F4R 730 was used across Renault's Laguna and Scénic platforms with transverse mounting. This engine received platform-specific adaptations-such as different intake manifolds and engine mounts-and was succeeded by the F4R 732 engine, creating clear generational boundaries. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the gearbox flange. The full code "F4R 730" should be clearly visible. Visually, it can be identified by its twin camshaft covers and distributorless ignition system with individual coil packs. It is distinct from the lower-output F4P 774 (133 PS) and the later, more powerful F4R 732 engines. Always verify the code stamping, as visual identification alone can be misleading.
The F4R 730's primary reliability risk is timing belt failure if neglected, with a secondary concern being exhaust manifold stud breakage. Renault service data from the late 1990s indicated a high correlation between missed belt changes and roadside breakdowns. While the non-interference design prevents engine destruction, neglecting this service makes unexpected immobilisation critical. Exhaust manifold issues, while not catastrophic, can lead to costly catalytic converter damage.
