Rimac Automobili now reaches a global audience by supplying one of its exclusive all-electric Concept_One supercars to the FIA Formula E Championship. It will be used by the championship’s Race Director during all city centre race events. This eye-catcher will be seen during track inspections and passenger laps.

Based in Croatia, near Zagreb, the electric car company works with a family of enthusiasts, engineers and designers that set up in 2009. To find new ways of making cars faster and to prove to the world that electric cars can be fun, they started with a blank sheet of paper with the idea to create an exceptional supercar with a new propulsion concept.

Rimac_Concept_One_underthehood_FEThe Concept_One features an advanced powertrain consisting of four individual drive systems, each consisting of a very powerful proprietary permanent magnet synchronous motor and gearbox unit. Each of the four systems drives its own wheel independently, introducing new levels of handling and adjustability through the Rimac-All-Wheel-Torque-Vectoring System. With a power output of 1088hp and torque levels of 1600Nm from 0 to 6500rpm, each wheel can also independently accelerate or decelerate in a fraction of a second helping to give superb handling and driving experience. The Concept_One can reach 100 km/h from standstill in 2.8 seconds and continues to accelerate over 300 km/h.

“Racing has always been the driver of innovation. It is the reason for our very existence as Rimac Automobili was born as the result of my passion for racing and electronics”, says Mate Rimac, CEO of Rimac Automobili. “We believe that the Formula E series will be an incubator for thousands of innovations and technologies that will contribute to the adaptation of electric drivetrain technology in many applications. It only makes sense that a car that is truly embracing the possibilities of the technology takes part in the series – the Concept_One shows already today what tomorrow’s technology can do. Our strong partnership with the Formula E series is a unique opportunity to push the limits even further.”
