Rimac Concept_One-3

Croatian company Rimac Automobili will be presenting an all-electric hypercar at the Geneva motor show. Named the Rimac Concept_One, the new hypercar is the production version of the model that was first shown at the 2011 Frankfurt motor show. In relation to that, it will be extremely rare as only eight units will be made.

Compared to the 2011 concept, the exterior has been slightly tweaked. It features a sleek grille and a bulging bonnet. In addition, it gets physical side-mirrors rather than cameras previously, and there’s also a carbon-fibre rear diffuser which is complemented by a pair of LED tail lamps. The electric hypercar sits on 20-inch lightweight alloy wheels shod with Pirelli P Zero tyres.

Providing power to the hypercar, are four permanent magnet electric motors, one for each wheel and located in the centre of both axles. Each of the four motors are coupled to a proprietary gearbox system – the front motors utilise single-speed gearboxes, while the rear gets a two-speed carbon-fibre, double-clutch gearbox with Formula 1 clutch discs on each side.

The electric motors and gearboxes allow for the Concept_One to push out 1,088 hp and 1,600 Nm of torque from zero to 6,500 rpm. The 1,850 kg hypercar goes from rest to 100 km/h in just 2.6 seconds, 200 km/h in 6.2 seconds and onwards to 300 km/h in just 14.2 seconds. It has a top speed of 355 km/h.

A total of 8,450 battery cells allows for the delivery of one megawatt (1,000 kW) of power during acceleration. In addition, it was also designed to absorb 400 kW during braking. Rimac says that a unique thermal management and low-resistance conducting system had to be developed to achieve this figure. There’s a 22 kW on-board charger, and a DC-Combo fast charger (up to 120 kW).

Also a unique feature, is the Rimac All Wheel Torque Vectoring (R-AWTV), which was conceived with the help of the hill climb to Pikes Peak. It uses input from several sensors positioned around the chassis and suspension to calculate optimal torque distribution. It controls each motor individually, one hundred times per second, providing “unseen flexibility and grip.”

Furthermore, the R-AWTV performs many other duties aside from torque distribution, according to the company. Said torque vectoring system also functions as a traction control, stability control and an ‘electric ABS’ system. Depending on preference, the R-AWTV system can work differently, depending on the driving modes; comfort, control, track and drift mode, or it can be turned off.

The Concept_One’s interior features only carbon and aluminium components, along with Alcantara upholstery. A bespoke Rimac Infotainment system with 4G connectivity, is capable of gathering real-time information of the car. Said system is also where the vehicle’s secondary functions are selected. The driving modes, are selectable via physical buttons machined from billet aluminium.

“My goal was to not to create an electric version of existing supercars. I wanted to create technology to make the supercar considerably better in every regard – faster, more fun and more efficient. I wanted to make the supercar of the 21st century. The Concept_One showcases performances which were not considered possible for electric cars a few years ago,” said Mate Rimac, CEO of Rimac Automobili.
