Rimac showed up to Geneva with the Concept One’s evil twin.

Remember that all-electric supercar known as the Rimac Concept One that debuted back in 2011? Well, Rimac came to Geneva this year, and it brought a new take on the Concept One, dubbing it the Concept S – the Concept One’s “evil twin.” To put it simply, the car has better aerodynamic qualities, more horsepower, more torque, and less weight, along with Rimac’s All Wheel Torque Vectoring system.

According to Rimac, this evil twin has been “tailored to deliver the style and comfort of a GT car,” with improvements to the car being based on the experience learned from the Rimac e-Runner’s amazing performance at the Pikes Peak International Hill Climb race in 2015. Even the inside of the car, specifically the infotainment system has been revised to make this concept the ultimate all-electric race car.

Founder and CEO of Rimac, Mate Rimac, said, “We wanted to use the experience and knowledge from the Pikes Peak and offer our customers a unique, racelike experience. The Concept_S pushes the levels of performance to the extremes. Focusing on performance, the set-up of the R-AWTV_S system has been adapted to give the driver the ability to use the maximum out of the tires and aerodynamics. Telemetry data is helping the driver to perform better, just like on GT-racecars.”

So let’s take a close look at Rimac’s new baby and see just what made it worth bringing to the Geneva Auto Show.

Looking at the exterior of the Concept S, you can clearly see the DNA from the Concept One, but this time, the car is more aggressive. Up front, that same grille in the front remains and is a functional cooling vent. To the sides, the two vents have been more refined and have baby blue inserts that give the front end a bit of accented livery. Down below, the Concept S has a beautiful front spoiler that also helps to apply a large amount of downforce to the front wheels. Downforce, by the way, is one of the main things that Rimac took into consideration when building this concept. With more than 1,000 horsepower, lots of downforce is needed to keep this monster from going airborne or losing traction. You probably recognize that hood too; it’s similar to the one on the Concept One, but that scoop in the center sits significantly higher. The headlights are also familiar, but it looks like the forward point has been shortened by about an inch or so.

Downforce, by the way, is one of the main things that Rimac took into consideration when building this concept

To the sides, pretty aggressive side skirts with an up-swept wing behind the front wheels have been added. As we move closer to the rear, we see the same vents at the rear quarter as on the Concept One, but the wheel arches are much more refined, losing the sharp body line that runs over the top of the rear quarter in favor of a smoother approach. The white and grey finish that runs from the outside edge of the front vents on the fascia back to the rear is also a nice touch. There is just something about two-tone paint jobs that always looks good on vehicles like this.

Moving to the rear, the Concept S looks to have the same taillights as the Concept One, with LED lights outlining a vent in the center. Below the tail lights there are two smaller vents integrated into the rear fascia. Here we see more of the gray livery across the majority of the rear fascia. The rear diffuser has six fins that are functional and help to create and air pocket behind the vehicle to help with downforce in the rear. The most obvious addition to the Concept S is the rear spoiler that also helps with downforce on the rear axle. The blue accenting from the front vents and wheel lips has been applied to the sides of the spoiler, with a gray finish covering the inner fin and the mounting arms.

Airflow passes through this vehicle in an elaborate fashion to cool and provide downforce in just the right areas. In case you can’t tell from the paint job, the gray paint actually symbolizes the path the air takes as it passes through and over the body. Not a bad touch, if you ask me.

Interior

Despite all of the new material in the interior, it is actually quite similar to the interior we saw in the Concept One

Despite all of the new material in the interior, it is actually quite similar to the interior we saw in the Concept One. This time, however, the interior looks to be almost completely covered in Alcantara. Panels that aren’t covered in Alcantara have a clear finish to expose the carbon fiber weaving. The inside is mainly black with some blue accents on the dash and around the center console. The seats also take a little bit of blue livery. The door trim panels, dashboard, steering wheel and parts of the seat are all stitched with red contrast stitching the matches the racing harness of both seats. It’s quite pleasurable to look at and probably pretty comfortable too.

The infotainment system was built in-house specifically for the Concept S. Rimac didn’t offer up the actual size of the touchscreen display, but it looks to be a 12-inch unit. The all-wheel torque vectoring system is controlled by physical buttons on the center console (made out of billet aluminum), but settings for the system, as well as brake force distribution, torque distribution, and other functions are all controlled by the touchscreen display.

More than 500 sensors supply information to the touch screen, where the data is stored and sent to a cloud through a 4G internet connection. Data from track routes can be analyzed during or after a race from the touchscreen or a mobile device.

Drivetrain

The Concept S can hit the 62 mph sprint in just 2.5 seconds

The experience gained from Pikes Peak last year allowed Rimac to refine and tune the AWTV system. The electric drive train now produces a total of 1,384 horsepower and 1,327 pound-feet of torque. The AWTV system calculates optimal torque distribution between each wheel and applies as needed. Each motor is controlled individually up to one hundred times a second. The same system also controls the electric ABS, traction control, and stability control. With one unit in charge of everything, the system can make near-immediate adjustments where it matters the most to provide the best torque and power distribution possible.

All told, the Concept S can hit the 62 mph sprint in just 2.5 seconds. A sprint to 124 mph comes in 5.6 seconds, and getting to 186 mph comes in a shockingly fast 13.1 seconds. Not bad for an all-electric drive train.

Conclusion

The Concept S does bring the world of supercars and electric cars together as the original Concept One did. In fact, with the increase of horsepower and torque, along with the more refined AWTV system, it really strengthens the connection between the two. On the other hand, I think Rimac could have been a little more creative with the body. Aside from different livery, some minor changes to the body, and some upgrades in the powertrain department, the Concept S is practically the same car as the Rimac Concept One.

I guess I have a little more appreciation for companies that go the extra mile to differentiate one model from the next. I would have liked to see different setups in the front and rear ends. Even the taillights and headlights are the same for the most part. I think it would have been better if Rimac designed the Concept S from the ground up instead of building on what it already had. Then again, I guess that really isn’t what the company was going for.

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 218 kW (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.

Back to the roots - with the vision of the future
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.

Rimac Automobili originates from the world of racing. The first car that turned its wheels coming out of, albeit, at that time, a small garage of Founder Mate Rimac, was the Rimac e-M E30. A converted 1986 BMW 3-series served as the test mule for numerous systems and was used by Mate Rimac to set five Guinness and FIA world records for electric cars.

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.

Extreme in every way
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.

Extreme aerodynamics
The Concept_S is all about maximum performance. To enhance grip at high speed the Concept_S features an extensive aero package. It all starts at the front where the splitter cuts through the air and generates downforce, pushing the front wheels to the ground. The air goes over the splitter, through the front intake, over the first four of the 7 cooling systems and out just before the front windshield. Part of the air is deflected by the side deflectors around the car, and as it hits the side skirts, more downforce is produced. The air is then grabbed by the side intakes and taken through the three remaining radiators and exits through the rear lights. Warm air meets with the air flowing under the car after it has been lifted upwards by the rear diffuser, filling up the low-pressure zone behind the car, thus minimizing drag. 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.

All this increases the downforce by 34 percent compared to the Concept_One, enabling grip levels of a highperformance racing car. More downforce not only enables more performance capabilities but also increases stability and safety at high speeds.

Concept_S R-AWTV_S
With 34 percent more downforce and high-performance tires, the Concept_S unlocks an even wider range of vehicle dynamics possibilities. Incorporating the experience gained at the Pikes Peak Hill Climb Rimac Racing introduces a more radical, bespoke R-AWTV_S system.

Distributing a total of 1018 kW / 1384 hp and 1800 Nm of torque, the Rimac All Wheel Torque Vectoring_S (RAWTV_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.

Concept_S Infotainment
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.

Browsing through the menus on the central display, the driver can change the settings of the Rimac All Wheel Torque Vectoring_S 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.

Compared to the Concept_One, the interface is more driving orientated, by focusing on data that is most important for spirited driving, thus keeping the driver focused on driving and maximizing his performance on the race track.

The Rimac Infotainment system gathers information from over 500 different sensors and displays them in an optimized way to inform the driver with minimal distraction. The data is stored in the internal memory and sent to the Cloud via high-speed 4G Internet link. The telemetry data can be analyzed during or after a lap on the racetrack, via the touch-screen, a PC or smartphone.

Raw and uncompromising
"We wanted to use the experience and knowledge from the Pikes Peak and offer our customers a unique, racelike experience. The Concept_S pushes the levels of performance to the extremes. Focusing on performance, the set-up of the R-AWTV_S system has been adapted to give the driver the ability to use the maximum out of the tires and aerodynamics.
