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 com…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The C1E 718 is generally very reliable for its era. Its main weakness is the exhaust manifold studs, which can break on high-mileage engines. With preventative replacement of these studs and strict adherence to the 60,000 km timing belt replacement schedule, it can easily surpass 200,000 km. Its simple design makes it inexpensive to maintain.
The most frequent issues are exhaust manifold stud failure causing noise, timing belt wear leading to potential engine damage, ignition coil failure causing misfires, and coolant temperature sensor failure affecting engine management. These are well-documented in Renault service information and are typical of engines from this period.
This 1.4L petrol engine was primarily used in the Renault Clio II (1996-2000) and the first-generation Renault Twingo (1996-2000). It was typically badged as the 1.4 in various trim levels (RN, RT, Campus).
Yes, within limits. Common upgrades include a performance air filter, a free-flow exhaust system, and ECU remapping. These can yield modest power gains of 5-10%. More significant power increases require internal modifications like a performance camshaft, which are less common due to the engine's age and design.
Good for its time. In a Renault Clio II, you can expect real-world figures of 7.0-8.0 L/100km (35-40 mpg UK) on a mixed cycle. Highway driving can see consumption drop to around 5.5-6.0 L/100km (47-51 mpg UK). Fuel economy is heavily influenced by driving style and vehicle condition.
Yes. The C1E 718 is an interference engine. If the timing belt breaks or jumps, the pistons will collide with the open valves, causing severe and expensive engine damage. This makes adhering to the 60,000 km timing belt replacement schedule absolutely critical.
Renault specifies RN0700 fully synthetic or semi-synthetic oil, typically in 10W-40 viscosity. This is essential for protecting the engine's internals and ensuring proper lubrication. Using the correct specification is important for engine health and longevity.
