We offer you acomprehensive breakdownof everything you need to know about this popular powertrain— specs, performance characteristics, common issues, tuning potential, and maintenance tips. Engine Overview: D4F 786 Specifications TheD4F 786 engineis a turbocharged variant of Renault’s D4F engine family. It is part of theTCE (Turbo Control Efficiency)range and was used in various Clio models and other compact Renault platforms.

  2. Specification Detail Engine Code D4F 786 Displacement 1,149 cc (1.2 liters) Engine Type Inline 4-cylinder, 16-valve Fuel Type Petrol Induction Turbocharged Maximum Power Output100 Hp (74 kW) at 5,500 rpm Maximum Torque 145 Nm at 3,000 rpm Valvetrain DOHC – Dual Overhead Camshafts Compression Ratio 9.8:1 Bore x Stroke 69.0 mm x 76.8 mm Fuel System Multi-point fuel injection Emission Standard Euro 4 / Euro 5 (varies by year) Performance Characteristics

  3. TheRenault Clio 1.2 TCE 100 Hp D4F 786deliversan impressive torque curveandfuel efficiency, making it ideal for urban and suburban driving. Despite its small displacement, the turbocharger boosts low-end torque significantly, offering lively acceleration and quick throttle response. •0-100 km/h:~11.0 seconds •Top Speed:190 km/h (118 mph) •Fuel Economy (Combined):~5.8 L/100 km •CO2 Emissions:135 g/km This engine shines in compact vehicles due to itspower-to-weight efficiency, and it offers more real-world drivability compared to naturally aspirated competitors in the same segment. Engineering and Design Advantages TheD4F 786engine integrates severalcutting-edge technologies: •Turbocharger with intercoolerfor enhanced power delivery. •Lightweight aluminum blockreduces vehicle weight. •Timing belt-driven camshaftsensure quiet and efficient valve operation. •Integrated exhaust manifoldfor quicker catalyst light-off and reduced emissions. These innovations make the D4F 786highly responsiveandmechanically robust, particularly for a downsized turbocharged petrol engine. Gearbox Pairing and Drivetrain Typically paired with a5-speed manual transmission, this engine deliverssmooth gear transitionsand excellentgear ratio spacing. The transmission allows for:

  4. •Efficient use of the torque band. •Good highway cruising behavior. •Low-end power accessibility without over-revving. Drivetrain layout:Front-Wheel Drive (FWD) Clutch type:Single dry plate Common Issues & Known Problems While generally reliable, theD4F 786 enginedoes present somemaintenance concernsover its service life: 1. Turbocharger Wear •Over time, the turbo unit can develop shaft play or oil leaks. •Avoid engine shutdown immediately after spirited driving—let the turbo cool. 2. Timing Belt Replacement •Recommended every100,000 km or 5 years. •Failure can lead tocatastrophic engine damagedue to its interference design. 3. Ignition Coil Failure •Misfires and rough idling may occur. •Replacing all four ignition coils at once is often the best approach. 4. Oil Consumption •Some owners reportexcessive oil usage, especially after 150,000 km. •Usehigh-quality 5W-40 synthetic oilto mitigate wear. 5. Carbon Build-Up

  5. •Due to direct injection,intake valve depositsmay occur. •Periodicengine decarbonizationis advised. Maintenance Schedule for Optimal Longevity Component Service Interval Engine Oil & FilterEvery 10,000 – 15,000 km Timing Belt Every 100,000 km or 5 years Spark Plugs Every 30,000 – 40,000 km Air Filter Every 20,000 km Coolant Every 5 years Brake Fluid Every 2 years Routine maintenance is critical. Stick to OEM parts and schedule regular inspections to ensure theD4F 786 engine performs optimally. Tuning and Performance Upgrades The1.2 TCE D4F 786has strong potential forsafe and effective tuning. Here are common modifications: Stage 1 ECU Remap •Gains: +15–20 Hp / +30 Nm torque

  6. •Improved throttle response andlower turbo lag Upgraded Intercooler •Better cooling =denser air intake = more power High-Flow Air Filter & Intake •Enhances breathing capability and improves engine tone Stainless Steel Exhaust System •Reduces back pressure, increasing responsiveness and mild power gain Be mindful offuel grade and thermal managementif going beyond Stage 1 tuning. Pros and Cons of the D4F 786 Engine Pros •High torque at low RPM •Fuel-efficient yet powerful •Lightweight design •Reliable when maintained correctly Cons •Sensitive to neglect (oil changes, timing belt) •Turbo longevity can be a concern •Carbon build-up risk over time Compatible Vehicles with the D4F 786 Engine TheRenault D4F 786engine can be found in several popular models:

  7. •Renault Clio III •Renault Modus •Dacia Sandero (select trims) •Renault Twingo (limited versions) Its compatibility and compact form factor make it a preferred choice for small cars demanding punchy performance. Comparison With Other Renault Engines Maintenance Cost Engine Power TurbochargedFuel Efficiency 100 Hp D4F 786 110 Hp K4M 708 H4Bt 400 (TCe 90) 90 Hp While newer engines like the H4Bt offer better emissions and fuel economy, theD4F 786 remains a solid middle groundfor cost, reliability, and driving enjoyment. Parts Availability and Cost Thanks to Renault'swide distribution, parts for theD4F 786 engineareeasily accessiblein Europe and many global markets.

  8. •Timing Kit (OEM):$150–$200 •Turbocharger (New):$400–$600 •ECU Remap:$250–$350 •Complete Engine (Used):$1,000–$1,500 Opt forgenuine or OEM-approved componentsto ensure proper fit and longevity. Final Thoughts TheRenault Clio 1.2 TCE 16V 100 Hp D4F 786 enginestrikes a rare balance betweencompact performance, fuel efficiency, and tuning potential. Whether you're buying, repairing, or upgrading, this engine deliversversatile performancein a well-engineered package. Proper care ensureslong-term reliability and fun behind the wheel.
