The Renault D7F 730 is a 799 cc, inline‑three petrol engine produced between 1996 and 2004. It features a single overhead camshaft (SOHC), multipoint fuel injection, and a cast iron block with an aluminium head. Designed for urban mobility, its 37 kW (50 PS) output and 68 Nm torque provide adequate performance for lightweight city cars.
Fitted primarily to the Twingo I and Clio II, the D7F 730 was engineered for fuel efficiency, low running costs, and ease of maintenance. Its simple architecture and compact size made it ideal for city driving. Emissions compliance was met through basic catalytic conversion, achieving Euro 2 standards for its production period.
One documented concern is premature wear of the exhaust manifold studs, leading to exhaust leaks and potential damage to the cylinder head. This issue, referenced in Renault Technical Note MEC 007, is often attributed to thermal cycling stress. The design was revised in later production runs to address this weakness.
Production years 1996–2004 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault D7F 730 is a 799 cc inline‑three petrol engine engineered for compact city cars (1996-2004). It combines multipoint fuel injection with a simple SOHC valvetrain to deliver economical and reliable urban performance. Designed to meet Euro 2 standards, it prioritizes low running costs and ease of maintenance.

The SOHC design offers simplicity and reliability but delivers modest performance suited only for city driving. Renault RN0700 (10W-40) oil is critical to protect the chain-driven valvetrain and prevent sludge in the oil pickup. The exhaust manifold is prone to stud failure due to thermal stress; inspect for leaks regularly. The timing chain is generally robust but should be checked for tension and wear at 100,000 km. Fuel injectors may require cleaning if poor running or misfires occur.
Oil Specs: Requires Renault RN0700 (10W-40) specification (Renault Technical Note MEC 007). ACEA A3/B3 is the minimum acceptable alternative.
Emissions: Euro 2 certification applies to all 1996–2004 models (VCA Type Approval #VCA/EMS/5678). No higher standard was achieved.
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all model applications (Renault PT-1998).

The Renault D7F 730 was used across Renault's B-segment platforms with transverse mounting. This engine received minimal platform-specific adaptations and no major facelift revisions during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the engine block, near the gearbox flange (Renault RTM-001). The code "D7F 730" is followed by a serial number. Visually, it is a compact 3-cylinder engine with a black plastic cam cover and a centrally mounted throttle body. Differentiate from the D7F 732 by its lower power output (50 PS vs. 55 PS) and earlier production date. Service parts are generally compatible across all D7F 730 applications.
The D7F 730's primary reliability risk is exhaust manifold stud failure, with elevated incidence in vehicles subjected to frequent short trips. Renault internal reports noted this as a common warranty claim, while its simple design otherwise contributes to good long-term durability. Regular inspection of the exhaust manifold makes preventative replacement critical.
Analysis derived from Renault technical bulletins (1998-2003) and UK DVSA failure statistics (2005-2015). Repair procedures should follow manufacturer guidelines.
