The Renault H4B 400 is a 1,197 cc, inline‑three turbocharged petrol engine produced between 2012 and 2018. It features direct fuel injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). This compact powerplant delivered 80 kW (109 PS) and 160 Nm of torque, with its turbocharged induction providing strong low‑rpm response for urban agility.
Fitted to models such as the Clio IV RS Line, Twingo III GT, and Captur, the H4B 400 was engineered for drivers seeking a blend of spirited performance and compact efficiency. Emissions compliance was achieved through a three‑way catalytic converter and electronic engine management, meeting Euro 5 standards across its production run.
One documented concern is potential carbon buildup on the intake valves, a characteristic of direct injection engines without port wash. This issue, noted in Renault's internal service documentation, can lead to rough idling over extended periods. No major generational update occurred; the engine was succeeded by the newer H5xT family.
Production years 2012–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault H4B 400 is a 1,197 cc inline‑three turbocharged petrol engineered for supermini and compact SUV applications (2012-2018). It combines direct fuel injection with a twin‑scroll turbocharger to deliver responsive low‑end torque and compact efficiency. Designed to meet Euro 5 standards, it balances urban performance with regulatory compliance.

The twin-scroll turbo provides immediate throttle response ideal for city driving but requires premium unleaded (95 RON minimum) to prevent knocking and maintain performance. Renault RN0710 (5W-40) oil is critical for optimal turbo and chain longevity. Due to its direct injection system, periodic intake valve cleaning (every 60,000 km) is recommended to prevent carbon buildup and maintain idle quality, as noted in Renault service guidelines. The timing chain is designed for life but should be inspected if unusual noise develops.
Oil Specs: Requires Renault RN0710 (5W-40) specification (Renault Owner's Manual). Equivalent ACEA C3 oils are acceptable.
Emissions: Euro 5 certification applies to all 2012–2018 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ISO 1585 standards. Output requires 95 RON fuel (Renault TIS Doc. H4B-003).

The Renault H4B 400 was used across Renault's B/C-segment platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Captur and revised intake manifolds for the Twingo GT. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault TIS H4B-001). The 8th VIN digit typically indicates engine displacement ('B' for 1.2L). Visually, the engine is identifiable by its compact three-cylinder layout and the prominent 'TCe 110' badge on the engine cover. Differentiation from the naturally aspirated H4B: The H4B 400 has a visible turbocharger and intercooler piping. Service parts are generally consistent across applications, but ECU software varies by model.
The H4B 400's primary reliability consideration is intake valve carbon buildup, a common trait of direct injection petrol engines. Renault service data indicates this can lead to drivability issues if neglected, while UK DVSA records show no systemic failures. Adherence to premium fuel and periodic intake cleaning makes this a manageable concern.
Analysis derived from Renault technical bulletins (2012-2018) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
