The Renault C1E 718 is a 1,390 cc, inline‑four naturally aspirated petrol engine produced between 1996 and 2000. It features a single overhead camshaft (SOHC) with 8 valves and multi-point fuel injection. This engine, part of the Energy family, was designed for balanced performance and fuel efficiency in compact hatchbacks.
Fitted to models such as the Clio II and Twingo, the C1E 718 was engineered for responsive urban driving and relaxed highway cruising. Emissions compliance for its production period was primarily achieved through a three-way catalytic converter, meeting Euro 2 standards.
One documented concern is premature failure of the exhaust manifold studs, which can lead to exhaust leaks and increased cabin noise. This issue, referenced in Renault Technical Note C1E7A, is often linked to thermal cycling stress. Later production runs saw revised stud materials to improve durability.
Production years 1996–2000 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/9600).
The Renault C1E 718 is a 1,390 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks (1996-2000). It combines a simple SOHC 8-valve design with multi-point fuel injection to deliver responsive, economical performance. Designed to meet Euro 2 standards, it balances everyday drivability with low running costs.

The SOHC design provides predictable, low-maintenance performance ideal for city and highway use but requires strict adherence to 60,000 km timing belt replacement intervals to prevent catastrophic failure. Renault RN0700 oil is specified for optimal engine protection. The exhaust manifold is a known failure point; pre-emptive replacement of the studs per Renault Technical Note C1E7A is recommended for high-mileage engines to prevent leaks and potential damage to the catalytic converter. Regular replacement of the fuel filter is advised to maintain injector performance.
Oil Specs: Requires Renault RN0700 specification (Renault Owner's Manual). ACEA A3/B3 is the underlying standard.
Emissions: Euro 2 certification applies to all 1996–2000 models (VCA Type Approval #VCA/EMS/9600).
Power Ratings: Measured under SAE J1349 standards. Output varies by application and ECU mapping (Renault TIS Doc. C1E-03).

The Renault C1E 718 was used across Renault's Clio II platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Twingo-creating minor interchange considerations. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface on the front face of the cylinder block, near the gearbox flange (Renault TIS C1E-01). The engine is visually identifiable by its black plastic rocker cover with 'Energy' branding and the Magneti Marelli injection system. Critical differentiation from later K4M engines: The C1E 718 uses a timing belt, while the K4M switched to a timing chain. Service parts, particularly for the timing system and exhaust manifold, are specific to the C1E 718 build.
The C1E 718's primary reliability risk is exhaust manifold stud failure, with elevated incidence in high-mileage engines. Renault internal service data indicates this is a common cause for workshop visits after 120,000 km, while owner reports frequently cite associated exhaust noise. Preventative stud replacement and strict timing belt intervals make long-term reliability excellent.
Analysis derived from Renault technical bulletins (1996-2000) and aggregated European owner workshop data (2005-2015). Repair procedures should follow manufacturer guidelines.
