Valeo’s 48V 2-Speed eAxle Brings Affordable Hybrid 4×4 Power to the Dacia Duster, Bigster & Striker

Reading Time: 11 minutes

Paris, France — 17 June 2026. Valeo, a global leader in automotive technology, has announced the commercial launch of its 48V 2-Speed eAxle with Smart Dog-Clutch — a world-first engineering solution that resolves one of the toughest trade-offs in affordable electrification: delivering rugged, high-torque 4×4 capability without exceeding Europe’s tightening emissions targets. The system has been selected by Dacia to power its new “Hybrid-G 150” powertrain, debuting on the Dacia Duster and Dacia Bigster, with the Dacia Striker following in the coming months.

This is not an incremental update to existing mild-hybrid architecture. According to Valeo, it is the first-ever combination of bi-fuel (Petrol/LPG) technology with an affordable electrified 4WD drivetrain — a configuration that directly targets cost-sensitive, high-volume SUV segments across Europe, where both fuel flexibility and genuine all-terrain capability remain non-negotiable purchase criteria for buyers.

What Is the Valeo 48V 2-Speed eAxle?

At its core, the Valeo 48V 2-Speed eAxle is an electric drive unit mounted at the rear axle that replaces the mechanical components traditionally used to send power from a front-mounted engine to the rear wheels in a 4×4 vehicle — driveshafts, transfer cases, and the associated hardware. Instead, Valeo’s solution integrates a self-contained, 48V-powered electric motor, an inverter, and a 2-speed transmission directly into the rear axle housing, generating drive force independently and electronically commanding the shift between two-wheel drive (2WD) and four-wheel drive (4WD) behavior.

This electrification of the rear axle is precisely what allows Valeo to describe the unit as a direct response to rising emissions costs that will be applied on traditional 4WD systems. By replacing heavier, less efficient mechanical drivetrain components with a more efficient electric drive, the system balances out the extra fuel consumption typically associated with traditional 4×4 architecture, helping vehicles meet strict European standards without sacrificing affordability.

How the System Shifts Between 2WD and 4WD

In standard driving conditions, the vehicle operates in efficient two-wheel-drive mode, powered by the front-mounted combustion engine. When additional traction is required — whether for acceleration assistance, slippery surfaces, or off-road terrain — the rear eAxle engages electronically, instantly delivering torque to the rear wheels and converting the vehicle into a genuine 4×4. Because the rear axle is driven independently by its own 48V electric motor rather than a mechanical link to the front powertrain, this transition is managed entirely through software and the Smart Dog-Clutch mechanism rather than through a conventional mechanical transfer case.

The Torque-Versus-Efficiency Trade-Off — And How Valeo Solved It

Historically, affordable electric axles have faced an inherent compromise: systems tuned to deliver strong low-speed torque for off-road climbing tend to sacrifice efficiency at higher cruising speeds, while systems optimized for highway efficiency typically lack the torque needed for steep climbs and extreme terrain. Valeo’s announcement identifies this as the central engineering problem the new eAxle was designed to solve.

The solution is a genuinely new 2-speed architecture, co-developed by Renault Group and Valeo, structured around three pillars:

• Extreme off-road performance via a short gear ratio: In this mode, the system delivers its full 1,800 Nm maximum of rear-wheel torque, providing what Valeo describes as the “SUV-strong” capability that Dacia customers expect for steep climbs and extreme terrain.

• High-speed efficiency via a long gear ratio: The system seamlessly shifts into this second ratio for efficient cruising at speeds of up to 140 km/h, prioritizing energy efficiency once maximum torque is no longer required.

• The Smart Dog-Clutch breakthrough: Rather than relying on a complex, costlier multi-plate clutch system, Valeo’s design is based on a simple dog clutch with software-synchronized speed engagement. This delivers premium-tier shifting performance at a cost compatible with entry-level vehicles — a critical detail for Dacia, a brand built on accessible pricing.

This combination is what makes Valeo’s system, in the company’s own words, a “world unique” 48V dual-speed system — engineering typically associated with premium electrified SUVs, repackaged for mass-market affordability.

Gear Ratio Modes Compared

Mode	Gear Ratio	Primary Function	Key Output
Off-road / low-speed	Short gear ratio	Maximum traction for steep climbs and extreme terrain	1,800 Nm peak rear-wheel torque
Cruising / high-speed	Long gear ratio	Efficient highway and motorway cruising	Efficient operation up to 140 km/h

Technical Breakdown: Inside the 41 kg Power Unit

Valeo describes the eAxle as the most powerful 48V rear electric powertrain currently on the market, a claim built on a tightly engineered, compact package. The unit’s specifications reflect a deliberate design philosophy: maximum capability within minimum mass and footprint.

Compact Integration Into B-Segment Platforms

A defining feature of the system is its compact design, which Valeo states allows integration into existing B-segment platforms. This is strategically significant: rather than requiring a bespoke vehicle architecture, the 48V 2-Speed eAxle is positioned as a cost-effective solution to upgrade existing Mild Hybrid Electric Vehicles (MHEV) with an electric rear-wheel-drive function. In practical terms, this means manufacturers can add genuine electrified 4WD capability to platforms that were not originally engineered around heavy electrification — a pathway that keeps incremental costs down and supports affordable pricing for the end customer.

Up to 60% Electric Urban Driving

Beyond off-road torque, the system is engineered for everyday efficiency. Valeo states that with the 48V 2-speed eAxle combined with optimized software strategies, Dacia has achieved up to 60% of urban driving in 100% electric mode on the Duster and Bigster. This figure is derived from internal testing using the urban (low) phase of the WLTC (Worldwide Harmonized Light Vehicles Test Cycle), and Valeo notes it represents a percentage of journey time that will vary according to real-world driving conditions — including road type, driving style, and weather conditions.

This figure matters because it speaks directly to one of the most common criticisms of mild-hybrid systems: that their electrification is largely cosmetic and contributes little to real-world emissions reduction. A 60% urban electric-driving share suggests the Hybrid-G 150 powertrain is delivering meaningfully more electric-driven distance than a conventional 48V mild hybrid without a dedicated electric rear axle.

Reliability and Extreme-Condition Validation

Affordable electrification only matters if it holds up to the demands of real ownership — particularly for a 4×4-badged vehicle expected to tow, wade, and traverse difficult terrain. Valeo addresses this directly, stating the system has been validated in extreme conditions and that its integration does not compromise the vehicle’s towing capacity or water-wading depth. The unit has been tested across an extreme temperature spectrum: from -30°C in Sweden to 45°C in Spain, covering both Nordic winter and Iberian summer extremes.

This breadth of validation directly answers a core market anxiety around electrified 4×4 systems: that adding electronics and battery-dependent components to an off-road drivetrain introduces new failure points or compromises the durability traditionally associated with mechanical 4WD. Valeo’s testing regime is positioned to neutralize that concern.

Strategic Context: Valeo, Dacia, and the Hybrid-G 150 Powertrain

The Partnership Behind the Innovation

The 48V 2-Speed eAxle is the product of close collaboration between two entities with deep, intertwined automotive expertise: Renault Group, Dacia’s parent company, and Valeo, the technology supplier. Valeo’s announcement explicitly credits this innovation as co-developed by Renault Group and Valeo — a partnership model that pairs Renault Group’s vehicle-level engineering and market knowledge of the Dacia customer base with Valeo’s specialized capability in electrification hardware and power electronics.

This eAxle has been selected by Dacia specifically for its new Hybrid-G 150 powertrain — a name that signals both the hybrid architecture and an approximate combined power output positioning within Dacia’s lineup.

Executive Perspective: Xavier Dupont, CEO of Valeo Power Division

Commenting on the launch, Xavier Dupont, CEO of Valeo Power Division, framed the technology as both a technical and strategic milestone for the company:

“We are proud to see Valeo’s innovative 48V 2-Speed eAxle at the heart of Dacia’s new Hybrid-G 150 4×4 powertrain. This breakthrough technology preserves the iconic 4×4 DNA of the Duster while significantly reducing its CO2 emissions. The collaboration with Dacia highlights our ability to scale electrification for the mass market and to provide the technology that supports our partners in the transition to sustainable, safe and all-terrain mobility.”

Dupont’s statement underscores a deliberate brand positioning: the eAxle is not framed as a replacement for the Duster’s off-road character, but as a preservation mechanism for it — allowing Dacia to retain the vehicle’s “4×4 DNA” while complying with tightening CO2 regulatory frameworks across Europe.

Why This Matters for European Emissions Targets

Valeo’s announcement is explicit that this system was engineered with regulatory pressure in mind. Traditional 4×4 systems carry an inherent fuel-consumption penalty due to the added weight and mechanical losses of transfer cases, driveshafts, and differentials running to the rear axle. As European emissions targets tighten, that penalty translates directly into rising compliance costs for manufacturers offering 4×4 variants.

By replacing mechanical components with an electric rear axle, Valeo’s system removes a significant share of that parasitic loss, while the bi-fuel Petrol/LPG compatibility adds a further emissions and running-cost lever — LPG being a lower-carbon, lower-cost fuel alternative already popular in several core Dacia markets. This is described as the first-ever combination of bi-fuel technology with an affordable electrified 4WD drivetrain, a configuration aimed squarely at value-conscious European buyers who want both 4×4 capability and lower running costs.

Production Timeline and Vehicle Rollout

Valeo’s announcement confirms a phased rollout schedule rather than a simultaneous, all-model launch. The Hybrid-G 150 powertrain, powered by the 48V 2-Speed eAxle, has already launched on the Dacia Duster and Dacia Bigster, with the Dacia Striker confirmed to follow in the coming months. The press release does not specify the exact manufacturing plant for the eAxle itself; the rollout details below reflect only what Valeo has officially confirmed regarding model timing.

Model	Rollout Status
Dacia Duster	Launched — Hybrid-G 150 powertrain available now
Dacia Bigster	Launched — Hybrid-G 150 powertrain available now
Dacia Striker	Confirmed — arriving in the coming months

Market Implications: Democratizing High-Performance, Affordable 4×4 Technology

Valeo’s positioning throughout the announcement repeatedly emphasizes one theme: democratization. The 1,800 Nm torque figure is explicitly described as “democratizing high-performance power” — language that signals Valeo’s ambition to bring capability previously reserved for premium electrified SUVs down into the B-segment, mass-market price bracket that defines the Dacia brand.

Several structural choices reinforce this affordability-first strategy:

• The Smart Dog-Clutch architecture was deliberately chosen over more complex, costlier clutch systems to keep manufacturing costs compatible with entry-level vehicles.

• The compact 41 kg unit integrates into existing B-segment platforms, avoiding the cost of bespoke vehicle architecture.

• The system serves as an upgrade path for existing MHEV platforms, allows manufacturers to add electrified rear-wheel drive without a full platform redesign.

Setting a New Standard for Hybrid 4×4 Mobility

Valeo’s own framing of the announcement positions this launch as a category-defining moment: by powering Dacia’s Hybrid-G 150 4×4 powertrain, the 48V eAxle “sets a new standard for hybrid 4×4 mobility,” proving — in the company’s words — that cutting-edge innovation can remain accessible without compromising on adventure-ready capabilities, and in certain conditions, even improving them.

For an industry where electrification has often been associated with rising sticker prices, particularly in performance and off-road-capable segments, this launch represents a notable counter-trend: a genuinely novel piece of electrified hardware engineered from the outset for cost compatibility with budget-segment vehicles, rather than being a trickle-down feature from premium platforms.

Implications for the Affordable Hybrid 4×4 Segment

The introduction of this technology on the Duster, Bigster, and, soon, the Striker has implications that extend beyond Dacia’s own lineup:

• Regulatory compliance without performance compromise: Manufacturers facing similar CO2 pressure on their 4×4 offerings now have a demonstrated, market-validated architecture to reference.

• A scalable electrification template: Because the system is designed for integration into B-segment platforms and as an MHEV upgrade path, the underlying approach is reusable across other affordable vehicle architectures, not just Dacia’s.

• Bi-fuel and electrification convergence: The pairing of Petrol/LPG bi-fuel technology with electrified 4WD opens a distinct value proposition for markets where LPG infrastructure and affordability remain strong purchase drivers.

Conclusion: A Defining Moment for Affordable Electrified 4x4s

Valeo’s 48V 2-Speed eAxle with Smart Dog-Clutch represents a genuinely engineered solution to a long-standing compromise in affordable vehicle electrification — the tension between rugged, high-torque capability and efficient, regulation-compliant everyday driving. With 1,800 Nm of peak torque, a 41 kg footprint, 31 hp peak output, and validated performance from -30°C to 45°C, the system backs its “world unique” claim with concrete, verifiable engineering metrics.

By powering Dacia’s new Hybrid-G 150 powertrain across the Duster, Bigster, and soon the Striker, Valeo and Renault Group have positioned this technology as proof that electrified 4×4 capability, bi-fuel flexibility, and European emissions compliance are not mutually exclusive — even within the most cost-sensitive segments of the European car market.
