Volvo Adds Pure-Biodiesel B100 Flex Option to the VM Truck Line

The Volvo VM B100 Flex is a medium-duty truck with a 360 hp (265 kW) engine that can run on pure biodiesel (B100) as well as on ordinary diesel blends.

Volvo presented it at the Fenatran 2026 trade show in São Paulo, Brazil, as an addition to its B100 Flex range. Volvo says that running on B100 can cut CO2 emissions by up to 90%, depending on the feedstock and the production method of the fuel.

The engine is adapted to the fuel by Volvo’s own software working through the sensors already on the truck, so no separate hardware is needed for different blends. The truck accepts blends from B15, the diesel with 15% biodiesel sold at Brazilian pumps today, up to B100.

On B15 the emissions are said to remain within the Euro 6 level (Brazil’s Proconve P8). Because the truck is not tied to one fuel, a transporter can switch between blends as supply allows, which Volvo says also helps resale value.

The B100 Flex option is offered for the 360 hp engine across the whole VM line, for road, urban distribution and off-road work. It can be ordered as a tractor unit or as a rigid platform truck, in any axle configuration. Pure B100 is not yet sold at filling stations, so fleets buy it from approved producers after notifying the national oil agency, ANP.

Volvo says the VM joins the FH and FMX, which already have B100 Flex versions, and that more than 200 B100 Flex trucks are in operation or on order in Brazil. Buyers can use financing from the BNDES Fundo Clima at 6.5% per year plus the BNDES rate of 1.3%, provided they submit a greenhouse-gas-reduction project that the bank approves.

Alcides Cavalcanti, executive director of Volvo Caminhões, called B100 Flex “the most direct alternative for immediate decarbonization”. The programme supports Volvo Group’s global goal of eliminating fossil-origin CO2 emissions from its vehicles by 2040.
