Rimac Concept_One Hypercar Finally Unveiled – Only Eight to Be Built
Rimac Automobili unveils the production version of the world’s first all-electric hypercar, the Concept_One, at the Geneva Motor Show 2016.
The Concept_One is powered by four extremely powerful permanent magnet electric motors, one for each wheel, located in the centre of both axles.
Distributing a total of 1088 hp and 1600 Nm of torque, the Rimac All Wheel Torque Vectoring (R-AWTV) system precisely calculates the optimum torque for each wheel at a 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.
All vehicle dynamics and powertrain functions such as the Rimac All Wheel Torque Vectoring System are controlled through physical buttons, machined from billet aluminium while secondary functions are controlled through the central touch-screen.
From basic energy consumption information via regenerative braking and Rimac All Wheel Torque Vectoring settings to telemetry data – the Rimac Infotainment system gathers information from over 500 different sensors and projects them in beautiful graphics on the central display in real time. The data is also recorded for later use and can be downloaded.
Every single part of the Concept_One has been through a hand-finishing process and is carefully assembled at the Rimac facility. All controls in the interior are beautifully crafted mechanisms similar to the world’s best watches, with hundreds of individual components, carved from solid blocks of metal. There are no plastic parts; everything the driver touches is carbon, aluminium or Alcantara.
An additional challenge for the concept is not just developing a battery that holds sufficient energy, but also to deliver one megawatt of power.
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.
While electric vehicles usually use a single-speed transmission, the Concept_One uses four propriety gearbox system, one for each motor. While the front motors feature single-speed gearboxes, the rear motors carry something truly unique – a two-speed double-clutch gearbox on each side.
