"Even primitive (DC) electric motors can outperform any combustion engine in almost all fields. Efficiency, extremely fast response, wide power band, compact size, regenerative braking, high torque... Those are just some advantages of our new permanent magnet synchronous motor generation which we developed exclusively for the Concept_One.
Our unique powertrain is divided into four sub-systems, each consisting of one motor, inverter and reduction gearbox. Each of those systems drives one wheel, completely independent one from the other. Sophisticated ECUs control each of those systems using the input of many precise sensors placed all over the car. This architecture allows a new approach to vehicle dynamics. We call it - All Wheel Torque Vectoring (AWTV).
Each wheel can independently accelerate or decelerate hundreds of times per second, helping to achieve the desired (driver selectable) handling. Together with the very low center of gravity, extremely high torque available almost from zero RPM and the lack of shift interruptions, the Concept_One delivers a completely new driving experience."
"With a curb weight of 1950 kg, and 1088 HP, the Concept_One can reach 100 km/h from standstill in 2.8 seconds and continues to accelerate over 300 km/h."
"One of the most innovative features of the Concept_One is the Rimac All Wheel Torque Vectoring System (R-AWTV), which distributes the power to each single wheel in every situation based on various input factors.
This system gives the Concept_One unique handling characteristics which can be adjusted by the driver. The driver can choose between a neutral and safe (understeer oriented) setup. Alternatively, if the driver has more skills and confidence, an oversteer setup can be chosen. This feature is not only a technological gimmick, it also improves safety since electric motors can react much faster compared to traditional stability control systems (ESP) which are using hydraulic brakes in order to influence the vehicle stability."
