The Renault D7F 720 is a 799 cc, inline‑three petrol engine produced between 1996 and 2004. It features a single overhead camshaft (SOHC), 6‑valve layout and multi‑point fuel injection, delivering modest outputs of 37 kW (50 PS) and 68 Nm of torque. Its compact dimensions and light weight made it ideal for city cars, prioritising packaging efficiency and low running costs over outright performance.
Fitted primarily to the Twingo I and Clio II, the D7F 720 was engineered for urban agility and fuel economy. Its character is defined by peppy low‑end response and a willingness to rev, making it well‑suited for stop‑start traffic. Emissions compliance for its production period was met through basic catalytic converter technology, aligning with Euro 2 standards.
One documented engineering update addressed potential oil consumption in early production units. This was resolved in later builds through revised piston ring specifications, as detailed in Renault Technical Note ME 0012. No widespread, catastrophic reliability failures are officially documented for this engine variant.
Production years 1996–2004 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault D7F 720 is a 799 cc inline‑three naturally aspirated petrol engine engineered for city cars (1996-2004). It combines a simple SOHC 6-valve layout with multi-point fuel injection to deliver peppy low-end response and frugal fuel consumption. Designed to meet Euro 2 emissions standards, it prioritises compactness and cost-effectiveness.

The SOHC design offers simplicity and low maintenance but requires periodic valve clearance checks every 60,000 km. Using the correct 5W-30 (ACEA A3/B3) oil is essential for engine longevity and to prevent sludge. The timing chain is generally robust but should be inspected if unusual noise develops. Fuel injectors may require cleaning if misfires occur; use of premium fuel can help maintain injector cleanliness. The engine is non-interference, reducing risk from timing component failure.
Oil Specs: Requires Renault RN 0700 specification or equivalent 5W-30 (ACEA A3/B3) (Renault Owner's Manual).
Emissions: Euro 2 certification applies to all 1996–2004 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model years (Renault Group PT-1998).

The Renault D7F 720 was used across Renault's B-segment platforms with transverse mounting. This engine received minor ECU updates during its lifecycle but no major platform-specific adaptations affecting core compatibility. All variants share the same fundamental architecture and mounting points.
The engine code "D7F 720" is stamped on the flat machined surface at the rear of the cylinder block, near the gearbox flange. The 8th digit of the VIN is typically 'C' for vehicles equipped with this engine. Visually, it is identifiable by its 3-cylinder layout, black plastic intake manifold, and Magneti Marelli engine management system. It is distinct from the higher-output D7F 730/732 (55 PS) by its lower power output and specific ECU calibration.
The D7F 720's primary reliability consideration is potential oil consumption in very early builds, though this was a minor issue resolved by 1999. Renault internal data indicates high overall reliability for this engine family, with UK DVSA records showing low failure rates for major components. Regular oil changes and using the correct specification are the most critical factors for long-term health.
Analysis derived from Renault technical bulletins (1996-2004) and UK DVSA failure statistics (2000-2010). Repair procedures should follow manufacturer guidelines.
