The Geneva International Motor Show 2016, which opens its doors to the public on March 3, emerges as the hall of electric and hybrid miracles as they predict some presentations of unique electric car from companies not so well known in the automotive world. Apart from a Chinese company with a powerful supercar, the revivial of the Spyker brand, also with an electric sport car, is anticipated. Morgan will present its classic three-wheeler in an electric mode ... and Rimac, the Croatian company for excellence in the field of electric supercars, will present its Concept-One, the best of hypercar available, which only occur in a limited series to eight units.
The Concept_One was born of the idea that an electric powertrain can make a sportscar not only faster but also more adjustable, agile and fun. Rimac Automobili was founded to push the limits of technology and electric powertrains - the Concept_One combines all the know-how, technology and experience that the company has created since its founding.
The Concept_One is powered by four extremely powerful permanent magnet electric motors, one for each wheel, located in the centre of both axles. The architecture is radically different compared to traditional combustion engines so a completely new vehicle platform had to be developed to use all the advantages that such a layout brings. In order to reduce weight and make it possible to package such a powerful powertrain system into the chassis, all powertrain systems were developed alongside within the same team to enable a high degree of integration between the components. The result is a perfect weight distribution and extremely low centre of gravity.
Distributing a total of 800 kW / 1088 HP and 1600 Nm of torque, the Rimac All Wheel Torque Vectoring (R-AWTV) system precisely calculates the optimum torque for each wheel. R-AWTV uses inputs from several precise sensors strategically positioned around the chassis and suspension to calculate the optimal torque distribution between the wheels through complex mathematical models and control algorithms. The system provides unseen flexibility and grip by controlling each motor individually one hundred times per second. This enables the Concept_One to accelerate from standstill to 100 km/h in just 2,6 seconds and, to 200 km/h in 6,2 and to 300 km/h in mind-blowing 14,2 seconds.
The Concept_One’s battery pack is designed to deliver 1000 kW or 1MW of power during acceleration and to absorb 400 kW during braking. A unique liquid thermal management and low-resistance conducting system had to be developed in order to master this challenge. The result is a highly advanced high-performance battery pack that is designed for demanding track- use, high power delivery and safety. Each of the 8450 battery cells is individually controlled through the in-house developed Rimac Battery Management System, which ensures optimal conditions for a long battery life and long-term performance.
