Horse begins production of HR13 flex fuel engine in Brazil

LONDON: Horse, a division of Horse Powertrain and a leader in innovative and low-emission powertrain systems, has started production of its 1.3-litre, 4-cylinder "HR13" engine at its facility in Curitiba, Brazil.

The flex fuel variant of Horse’s HR13 turbo engine has been engineered specifically for the South American market. It can seamlessly run on gasoline and ethanol blends that are staples of Brazilian mobility and is fully compliant with L8 emissions standards.

The powertrain delivers peak power of 163PS (161hp), as well as peak torque load of 250Nm at just 1,600rpm.

The start of HR13 production adds to Horse’s growing production abilities in Brazil, following the start of production of its 1.0-litre, 3-cylinder "HR10" engine in 2024.

The HR13 benefits from a bespoke direct injection system that’s been developed specially for ethanol fuel use. Each cylinder is accompanied by a centrally mounted six-hole injectors operating at 200 bar pressure, tailored for exceptional fuel atomisation that delivers effortless power and torque without impacting fuel efficiency.

Enabled by a recent R$100 million (RM77mil) investment in the Curitiba facility, HR13 production will be a key output of the plant, which has capacity to produce up to 600,000 units annually across its portfolio of engines.

In 2024, Horse also announced an investment in a gravity-casting process to produce aluminium cylinder heads for both the HR10 and HR13 engines, as well as expanding its powertrain and emissions testing facilities to service third-party manufacturers in the region.

Horse was created to provide highly efficient, low-emission engines, transmissions, and technologies to meet the varying power generation needs around the world.

Horse operates eight production plants across seven countries, three R&D centres and a head office based in Madrid, Spain – the company produces 3.2 million units per year for its customers around the world.
