The Tajima Rimac E-Runner Concept_One is powered by four independent electric motors that give the car a total power output of more than 1.1 megawatts, which is equivalent to approximately 1455bhp.
The drivetrain is housed in an aluminium alloy tubular space frame produced by Tajima’s Monster Sport preparation company and is clad in a carbonfibre body.
The car has no gearboxes or differentials; instead the power of each independent motor is transferred to each wheel by a chain drive system developed specifically for this project. The system is said by Rimac to bring weight savings and packaging benefits.
The Tajima Rimac E-Runner Concept_One features an adapted racing version of Rimac’s All Wheel Torque Vectoring system, first used on the Rimac Concept_One road car. The system controls the torque of each motor 100 times a second and can vary the torque on each wheel depending on the steering angle, speed, longitudinal and lateral forces, yaw rates and a number of other variables.
Maximum torque is a claimed at 1106lb ft. A 57kWh battery pack provides the power and the car also features regenerative braking that can supply up to 536bhp of the total power.
The vehicle weighs 1500kg, and Rimac’s tests have produced some impressive performance figures.
“We measured 0-62mph in 2.2sec,” said company founder Mate Rimac. "124mph comes in 5.4sec from a standstill. We are quite confident that Tajima Rimac E-Runner Concept_One will break the previous year’s record."
