2026 Renault Duster Engine Options: The all-new Renault Duster marks a significant return to the Indian market with a trio of sophisticated petrol powertrains. From the accessible 1.0-litre turbo to the Formula 1-derived strong hybrid, here’s everything you need to know about the engines powering Renault’s flagship SUV.
Introduction: A New Era of Powertrains
The 2026 Renault Duster represents a complete departure from its predecessor’s engine philosophy. Gone are the diesel options that once defined the Duster’s appeal. In their place, Renault offers three distinct petrol powertrains: a 1.0-litre turbo-petrol for entry-level buyers, a 1.3-litre turbo-petrol for performance enthusiasts, and a groundbreaking 1.8-litre strong hybrid for efficiency-focused customers.
Each engine tells a story of global collaboration, technological innovation, and shared development across multiple automotive giants. Let’s examine each powertrain in comprehensive detail.
Engine 1: The 1.0-Litre Turbo-Petrol (HR10)
Overview and Positioning
The entry-level engine in the 2026 Duster lineup is the familiar 1.0-litre turbocharged three-cylinder unit, internally codenamed HR10. This powerplant serves as the gateway to Duster ownership, offering a balance of affordability, efficiency, and adequate performance for urban-focused buyers.

Development History
The HR10 engine is part of Nissan’s extensive HR engine family, co-developed with Renault under the Renault-Nissan-Mitsubishi Alliance framework. The engine’s development began in the mid-2010s as a downsized derivative of the larger HR13 1.3-litre unit.
The HR10DET (turbocharged variant) made its global debut in the fifth-generation Nissan Micra in 2017. The engine was specifically engineered to replace older naturally aspirated units while meeting increasingly stringent Euro 6 and BS6 emission norms.
Key development milestones include:
- 2016-2017: Initial development and testing
- 2017: Global launch in Nissan Micra (Europe)
- 2019: Introduction in Renault Triber (India) in naturally aspirated form
- 2021: Launch in Renault Kiger and Nissan Magnite with turbo variant
- 2026: Implementation in new-generation Duster
Architecture and Engineering Details
The HR10 engine features an all-aluminium construction for reduced weight. The cylinder block uses an open-deck design with integrated water jackets for optimal thermal management. The DOHC cylinder head incorporates hydraulic lash adjusters, eliminating the need for periodic valve clearance adjustments.
The turbocharging system employs a small-diameter turbine optimised for low-end response. An electronic wastegate provides precise boost control, while the intercooler reduces intake temperatures for improved volumetric efficiency.
Notable engineering features include:
- Variable Valve Timing (VVT): Dual independent cam phasers on intake and exhaust
- Mirror Bore Coating: Plasma-sprayed cylinder walls reduce friction
- Low-Friction Timing Chain: Lifetime component requiring no scheduled replacement
- Integrated Exhaust Manifold: Turbo housing integrated with head for faster warm-up

Formula 1 DNA: The E-Tech Technology Story
Renault’s E-Tech hybrid technology traces its roots directly to the company’s Formula 1 programme. The energy management strategies, regenerative braking algorithms, and power flow optimisation techniques were developed through Renault’s involvement in F1 since the introduction of hybrid powertrains in 2014.
Key F1-Derived Technologies:
- KERS Heritage: The Kinetic Energy Recovery System (KERS), introduced in F1 in 2009, forms the conceptual foundation of E-Tech’s regenerative capabilities.
- Energy Management Algorithms: Software developed for managing the complex energy flows in F1 hybrid power units was adapted for road car applications.
- Dog Clutch Gearbox: The clutchless multi-mode transmission uses dog engagement (like F1 gearboxes) instead of synchromesh, enabling faster, smoother shifts with reduced energy losses.
- 150+ Patents: The E-Tech system is protected by over 150 patents, many derived from F1 racing technology.
E-Tech Hybrid System Architecture
The E-Tech Strong Hybrid uses a series-parallel architecture, combining the advantages of both hybrid configurations:
Series Mode:
- Electric motor drives wheels exclusively
- Petrol engine acts as generator to charge battery

- Maximum power for acceleration and highway driving
- Electric motor provides torque fill during gear changes
Combined Mode:
- Intelligent ECU seamlessly switches between modes
- 15 different combinations possible between thermal and electric operation
- Optimises for either efficiency or performance based on driving conditions
The Revolutionary Multi-Mode Gearbox
Unlike conventional CVT-based hybrids (Toyota, Honda), Renault’s E-Tech uses a fixed-gear ratio transmission with dog clutch engagement:
Transmission Structure:
- 2 gears for the main electric motor (E-Motor)
- 4 gears for the petrol engine
- 15 possible power flow combinations
- No synchronisers or torque converter
- Electronic e-shifter for gear selection
Benefits:
- Faster gear changes than CVT
- More direct, engaging driving feel
- Reduced mechanical losses
- Better efficiency than planetary gear hybrids
- No CVT “rubber band” sensation

Key Features:
- High-pressure direct injection at 350 bar
- High compression ratio optimised for Atkinson cycle
- Variable valve timing with electric cam phasing
- Integrated water-cooled exhaust manifold
- Low-friction components throughout
Battery System
The E-Tech Strong Hybrid employs a 1.4 kWh lithium-ion battery pack:

Motors77 Verdict
The 2026 Renault Duster’s engine lineup represents a strategic masterclass in powertrain diversification. Each option serves a distinct customer need while sharing underlying development philosophies focused on efficiency, refinement, and global quality standards.
The 1.0-litre turbo democratises Duster ownership, the 1.3-litre turbo delivers premium performance credentials backed by Mercedes-Benz collaboration, and the 1.8-litre strong hybrid positions the Duster at the forefront of electrification in its segment.
For most buyers, the 1.3-litre turbo represents the best value proposition, offering robust performance, proven reliability, and reasonable efficiency. However, the strong hybrid deserves serious consideration for those who prioritise running costs over initial price — its claimed 40% fuel savings could offset the premium within 3-4 years of typical ownership.
What’s clear is that Renault has left no stone unturned in ensuring the new Duster has the powertrain firepower to compete with the best in the segment. The absence of diesel is noteworthy, but the comprehensive petrol and hybrid offerings more than compensate for this omission.
