SHERIDAN, WYOMING - December 5, 2025 - Stellantis is launching the HVO Aurora project as a practical way for European light commercial vehicle (LCV) fleets to certify the real-world use of renewable diesel, turning low-carbon fuel consumption into traceable data that supports decarbonization strategies and day-to-day operations.
HVO Aurora tracks real-world use of renewable diesel
HVO Aurora is built around Hydrotreated Vegetable Oil (HVO), a renewable fuel produced from waste streams such as used cooking oil and animal fats. By design, it targets a key question for fleet operators: how to prove that vehicles are actually running on low-carbon fuel in daily use, not just on paper.
The project provides a monitoring and reporting system that records fuel type, trip distance and consumption and uploads this information securely to the cloud. Fleet managers get transparent, auditable proof of HVO usage and associated CO₂ reductions, enabling them to link procurement decisions to measurable climate impact.
Data-driven certification for low-carbon fleet operations
At the heart of HVO Aurora is an easy-to-use tracking and certification layer designed for business customers. Rather than requiring new platforms or complex retrofits, the system sits on top of existing LCV fleets, capturing fuel data as drivers go about their normal routes.
"HVO Aurora shows how we can reduce well-to-wheel emissions immediately, using solutions that work with the vehicles our customers already rely on," said Luca Marengo, Head of Product and Innovation for Stellantis Pro One. "At Stellantis Pro One, we remain committed to providing practical and scalable ways to help businesses reduce full cycle emissions now. This project is a concrete step forward in building a cleaner future for mobility in Europe."
By turning HVO consumption into structured data, the project gives companies a way to substantiate sustainability claims, respond to customer and regulatory demands for verifiable CO₂ reductions, and integrate fuel choice into broader ESG reporting.
European road tour with SP3H to prove concept at scale
To demonstrate the concept under real-world conditions, Stellantis has kicked off a month-long European road tour in collaboration with SP3H, a French specialist in intelligent sensors for low-carbon fuels. Two Stellantis vans-a Citroën Berlingo and a Fiat Professional Ducato-have been equipped with SP3H's connected FluidBox Micro sensor and sent on a multi-country journey across Europe.
As the vehicles travel, the SP3H FluidBOX platform continuously transmits usage data confirming HVO fueling and estimating CO₂ savings. The tour is designed to show fleet decision-makers that:
- Renewable fuels can be used in existing vehicles without hardware changes.
- HVO usage can be monitored and certified in real time.
- Measurable well-to-wheel CO₂ reductions are achievable with current infrastructure.
Complementing electrification with drop-in renewable fuel
HVO Aurora is positioned as a complementary pathway to cleaner mobility alongside electrification and other low-emission technologies. A key advantage for fleets is that all Stellantis passenger cars and light-duty commercial vehicles currently on sale are already fully compatible with HVO diesel fuel conforming to the EN15940 standard.
Many Euro 5 and Euro 6 diesel vehicles already on European roads can also use HVO without modification. That means operators can begin cutting emissions immediately by switching fuel and adding HVO Aurora's tracking layer, rather than waiting for full fleet turnover to battery-electric or other advanced drivetrains.
Immediate implications for LCV fleet managers in Europe
Companies under pressure to reduce their environmental footprint often struggle to reconcile long-term transformation plans with short-term operational realities. HVO Aurora is designed to bridge that gap by enabling fleets to:
- Use renewable fuel in existing Stellantis LCVs with no infrastructure overhaul.
- Track and certify HVO usage at vehicle and fleet level.
- Quantify CO₂ savings and integrate them into sustainability reporting.
Born from Stellantis' internal Star*Up intrapreneurship program and backed by the Stellantis Pro One commercial vehicles business unit, the initiative signals how OEMs are moving beyond vehicle sales to offer data-rich services that support customers' decarbonization strategies. For European fleets looking for concrete, near-term levers to cut emissions, HVO Aurora offers a pragmatic, immediately deployable option.
