BMW Group and Italian energy company Eni have agreed to power BMW corporate fleet vehicles in Italy with HVOlution, a diesel biofuel made entirely from renewable feedstocks by Eni’s mobility arm Enilive. The move extends BMW’s push to cut tailpipe emissions from the diesels already on the road, alongside its electric and hybrid line-up. The fuel is a drop-in replacement that works in validated diesel engines with no hardware changes.

BMW Group and Eni have announced an agreement to fuel BMW corporate fleet vehicles in Italy with HVOlution, a 100% pure HVO (Hydrotreated Vegetable Oil) diesel biofuel produced from fully renewable feedstocks. The fuel comes from Enilive, Eni’s company focused on more sustainable mobility products and services.

For BMW, the deal is part of a broader strategy the company describes as working towards an “Eligible Fuels only-fleet” for its customers. The manufacturer frames pure HVO as a solution that can reduce emissions from diesel vehicles that are already in use, rather than waiting for the fleet to turn over to electric power.

How much CO₂ it saves

According to Eni, in 2025 the average reduction in CO₂-equivalent emissions from all of Enilive’s HVO produced across the entire supply chain was 79.5% compared with the reference fossil mix. That figure is measured under the EU Renewable Energy Directive (RED) methodology and weighted by the feedstock batches actually processed at Enilive’s biorefineries in Venice and Gela, which the company says run mainly on waste and residues such as used cooking oil and animal fats.

Because pure HVO is a so-called drop-in fuel, Enilive says it needs no changes to engines or distribution infrastructure — a point the company uses to argue it can cut transport emissions immediately.

Fleets across three countries

BMW Group has recently started running demonstration and development diesel fleets on pure HVO. The corporate fleet vehicles involved travel across Italy, Germany and Austria, where a network of around 1,700 Enilive stations sells HVOlution.

The company is also trialling a traceability system in the fleet vehicles: refuelling data from the cars is compared with data from the fleet operators’ payment systems, so the fuel used by each vehicle can be tracked seamlessly and transparently.

Which BMW diesels can use it

BMW Group says it has approved HVO diesel fuels — which meet the European EN 15940 standard — for its diesel models registered from late 2014 onwards and fitted with a Generation B diesel engine. To raise awareness of the fuel, BMW Italia is giving an Enilive HVOlution voucher to every customer buying a new BMW diesel in Italy.

“We are very happy to collaborate with Eni in our test and demo fleet. In this case this has more than one benefit: Eni is using BMW vehicles in their corporate fleet, at the same time is Enilive a major force in pushing renewable fuels in Europe. With HVOlution, Enilive has a very good product available delivering CO₂eq emissions reduction every day,” said Dr. Martin Kaufmann, SVP Powertrain Development at BMW Group.

Stefano Ballista, Chief Executive Officer of Enilive, called the deal “another significant step toward the decarbonization of road transport” and “a tangible example of integrated partnership between the automotive and energy industries.”

What it means

With more than 250 million vehicles already on Europe’s roads, BMW argues that raising the share of renewable fuels could improve the CO₂ footprint of the existing fleet without owners buying new cars. The agreement sits alongside the company’s wider electric and hybrid technologies rather than replacing them, and follows an earlier tie-up between Eni and BMW Italia. As with any drop-in fuel, its real-world impact depends on how widely it is available and used.
