Aurobay Engines Power ARC2 Rally2 Car for US RC2 Debut
Horse Powertrain, through its Aurobay Technologies division, has agreed to supply a Swedish-built 2.0-litre turbocharged engine for JRD Motorsport’s ARC2, a new rally car developed for the American Rally Association’s RC2 class. Aurobay will ship each engine fully assembled, fitted with a locked ECU and tamper-proof seals, guaranteeing full FIA Rally2 compliance. SGS Racing Transmission will mate the powerplant to a five-speed sequential gearbox, creating a robust drivetrain for gravel and tarmac stages.
“This is an exciting moment for Horse Powertrain, marking our first direct deal with a US customer. I believe our solutions and expertise can be of great value to automakers and original equipment manufacturers (OEMs) in this region. This agreement also highlights the versatility and competitiveness of our technologies in motorsport applications. We are proud to support JRD Motorsport’s ambition with a proven, high-performance solution developed and built by our team in Sweden,” says Matias Giannini, CEO of Horse Powertrain.
JRD Motorsport builds the ARC2 on a Chevrolet Sonic platform, integrating all-wheel drive, an FIA-certified roll cage and proprietary suspension geometry engineered in-house. The project aims to deliver Rally2-level performance at a fraction of the cost of imported European alternatives, widening access for American rally teams.
“Our objective has been to provide a competitive, reliable car that is affordable for American teams. Horse Powertrain’s engine has been essential in achieving this, allowing our new ARC2 rally car to offer world-class performance to racers at a very competitive value,” adds Johan Ragnarsson, CEO of JRD Motorsport.
The ARC2 will make its public debut at the Performance Racing Industry Show in Indianapolis in December 2025. JRD Motorsport intends to start testing later that year, with customer deliveries scheduled for early 2026.
