R-AWTV – SAGGYSTUNZ

Rimac Automobili, an automobile manufacturing company established in 2009 By Mate Rimac in Zagreb, Croatia. Mate Rimac’s objective was to build an Electric Supercar Started on a sheet of paper, As there was a compromise in owning a electric car which was the performance, The company developed their own electric systems and they do have some 24 patents on their name,

It all started when Mate was racing in 1984 his engine blew up so he put his 600 HP powertrain in that car and called it a “GREEN MONSTER” which set fastest accleration record which triggered Mate’s ideas then the investors started coming in to invest on his ideas.

Concept One was introduced in 2011 Frankfurt Moor show,The Rimac Concept One is a two-seat high-performance electric car designed and manufactured in Croatia by Rimac Automobili, Concept One has been described as the world’s first electric supercar. This car carries a price tag of $1 million( ₹ 6.5 Crores).

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.The R-AWTV functions as a traction control, stability control and “electric ABS” system that also commands the 4-wheel regenerative braking of up to 400 kW that works together with the carbon-ceramic braking system.

To match the character, innovation excellence and sleek design of the Concept_One, a truly bespoke infotainment system was developed and manufactured in-house. 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. The system shows an abundance of information through beautifully optimised graphics and gives insights into the Concept_One’s nervous system. Browsing through the menus on the central display, the driver can change the settings of the Rimac All Wheel Torque Vectoring system, brake force distribution, torque distribution, as well as various other functions. By changing the settings, the driver alternates the nature of the car depending on his preferences, from a calm and neutral setting to a track-oriented setup or the extreme drift mode that helps experienced drivers to have fun on a closed track.

Four motors, four gearboxes

Despite having full torque from zero RPM, electric motors still need a transmission to meet maximum efficiency and performance. Most electric vehicles use a single-speed transmission that forces their designers to compromise between acceleration and top-speed.

Rimac Automobili is all about innovation and pushing the limits – not about compromises. They wanted to achieve lightning-fast acceleration and a top speed worthy of a true supercar. In order to meet those targets, They had to come up with a unique solution.

Each of the four Concept_One’s motors is coupled to a proprietary gearbox system. While the front motors feature single-speed gearboxes, the rear motors carry something truly unique – a two-speed double-clutch gearbox on each side. A proprietary carbon fibre double clutch system with Formula 1 clutch-disks enables either extremely fast or smooth and comfortable shifts that are supported by synchronising motor speed for interruption-free shifting. While the dual-speed transmission unlocks new performance levels at any speed, the Concept_One can be driven in one gear all the time as it has enough torque to outperform almost any sportscar even if driven in one gear only.
