Rimac Concept S
The Rimac Concept_S is built to utilize
the maximum potential of the Rimac All Wheel Torque Vectoring system. Compared
to the Concept_One, the Concept_S has 296 hp and 200 Nm more power and
torque, 50 kg less weight, and an aggressive aerodynamic package. The
aerodynamic elements enhance downforce by 34 % (up to 650 kg of load) which
press the chassis to the ground. Combined with high-performance tires, higher
levels of grip are enabled opening a wide spectrum of extreme setups for the
Rimac All Wheel Torque Vectoring (RAWTV) system. With 1384 hp and 1800 Nm of
torque, the Concept_S raises the bar of dynamic performance.
Rimac Concept_S is based on the
Concept_One that has been tailored to deliver the style and comfort of a GT
car. Powerful, agile and adaptive, the Concept_One offers a completely new
driving experience of a hypercar from the future. The design features sleek,
smooth but determined lines that enable great aerodynamic efficiency with low
drag. The Concept_S has been redesigned to incorporate an extreme aerodynamic
package and tires with even more grip, reaching maximum performance.
The Concept_S was developed within the
extremely vertically integrated organization of Rimac Automobili, which enables
a firm synergy between engineers from various backgrounds and departments to
collaborate and find the best path to raise the bar. With the development of
the Concept_One, Rimac Racing stayed true to their roots, working on motorsport
programs at the highest level. The hardest test for Rimac All Wheel Torque
Vectoring was the Pikes Peak International Hill Climb Race in Colorado.
Nobuhiro Monster Tajima drove the Tajima Rimac e-Runner, a race car developed
by Rimac Automobili, on the Pikes Peak International Hill Climb 2015 and
finished in front of all combustion engine powered cars. The invaluable
experience gathered during the Pikes Peak project has been implemented
throughout the development of the Concept_One's R-AWTV system. The result is a
refined, yet powerful system that works in the background to enhance the
natural potential of the vehicle.
The experience gathered during the Pikes
Peak program was implemented in the Concept_One and adapted to suit the comfort
and performance of a hypercar on road tires. Knowing how much the RAWTV system
can provide on racing tires, Rimac Automobili decided to awake the Evil Twin,
the Concept_S.
Featuring a big front splitter, air
deflectors, side skirts, diffuser together with a large rear spoiler, the
Concept_S comes with greater aerodynamic downforce. Different carbon-fibre
materials and lay-ups are used to reduce the weight of bodywork by 7 percent.
The interior is stripped of sound insulation with minimized use of materials
and a toned-down design so that the driving excitement can take center stage.
Racing seats with four-point racing harness ensure a fixed and focused driving
position.
Alcantara trim with red stitching and
blue lines on the seats converge with the exterior details. The raw racing
character is underlined by long stretched curved features of naked carbon
fibre. The CNC machined buttons and knobs on the center console unit are
anodized in red, enhancing the racing feeling and accompanying the focused infotainment
system that projects only the most important information on the central display
and the digital instrument cluster.
The Rimac Concept_S is all about maximum
performance. To enhance grip at high speed the Concept_S features an extensive
aero package. As the Concept_S cuts through the air, the spoiler produces
downforce for the rear end, giving the rear wheels more grip needed to put the
1384 HP down to the ground.
Distributing a total of 1384
hp and 1800 Nm of torque, the Rimac All Wheel Torque Vectoring_S (R-AWTV_S)
system precisely calculates the optimum torque for each wheel. R-AWTV_S 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_S to accelerate from standstill to
100 km/h in just 2,5 seconds, to 200 km/h in 5,6 and to 300 km/h in mesmerising
13,1 seconds. The R-AWTV_S functions as a traction control, stability control
and "electric ABS" system which 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 performance of the Concept_S, 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_S 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 optimized graphics and
gives insights into the Concept_S's nervous system.
