Rimac Automobili announced a 2016 Geneva Motor Show entry with its electric supercar Concept_Oneproduction version“.

The term “production version” suggests to us that since unveiling of the concept in 2011, all the cars seen to date weren’t production, more like prototypes. Rimac says that current version is fourth iteration.

Concept, prototype or production – that doesn’t change that  Concept_One will be extremely rare car. Only eight units to be produced!

Spec of Rimac Concept_One is now updated including mind-blowing performances:

  • 0-100 km/h (62 mph) in 2.6 seconds
  • 0-200 km/h in 6.2 seconds
  • 0-300 km/h in 14.2 seconds

2016 Rimac Concept_One – motors

Concept_One is equipped with four permanent magnet motors – one for each wheel, with total 800 kW / 1088 HP and 1600 Nm of torque.

Front motors drive wheels through individual single speed gearboxes. Rear motors have individual double clutch two-speed gearboxes, but you 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“.

Lithium-ion battery consists 8,450 cells and is pretty strong, providing of up to 1000 kW of power and capable of up to 400 kW regen! Total capacity stands at 82 kWh.

For charging there is 22 kW on-board charger and 120 kW DC Combo capability (just in case you could find somewhere with a 120 kW Combo charger).

Concept_One production version to be unveiled in Geneva

Rimac Automobili will unveil the production version of the world’s first all-electric hypercar, the Concept_One, at the Geneva Motor Show 2016.

The Concept_One was born  of the idea that an electric powertrain can make a sportscar not only faster but also more adjustable, agile and fun. Rimac Automobili was founded to push the limits of technology and electric powertrains – the Concept_One combines all the know-how, technology and experience that the company has created since its founding.

2016 Rimac Concept_One

The Concept_One is powered by four extremely powerful permanent magnet electric motors, one for each wheel, located in the centre of both axles. The architecture is radically different compared to traditional combustion engines so a completely new vehicle platform had to be developed to use all the advantages that such a layout brings. In order to reduce weight and make it possible to package such a powerful powertrain system into the chassis, all powertrain systems were developed alongside within the same team to enable a high degree of integration between the components. The result is a perfect weight distribution and extremely low centre of gravity.
Distributing a total of 800 kW / 1088 HP and 1600 Nm of torque, the 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.  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.

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.

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 stored in  the internal memory and sent to the Cloud via high-speed 4G Internet link. The telemetry data can be analysed during or after a lap on the racetrack, via the touch-screen, a PC or smartphone.

Handmade technology of the future
In the five years of development, the Concept_One went through numerous iterations and development phases to fulfil the highest criteria of performance and quality.

In the words of the founder and CEO of Rimac Automobili, Mate Rimac: “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. To reach that level of performance, we first had to develop the technology and then the car. The Concept_One has gone through four iterations from a concept to the production car. In every iteration, we have redesigned almost all systems from scratch in order to achieve the level of performance and quality that we have set for ourselves in the beginning. I am also extremely proud of our vertical integration – the Concept_One is a true Rimac Automobili product – down to the smallest details.”

Rimac Automobili’s Head of Design, Adriano Mudri: “It is quite unique that a whole car can be designed, developed and manufactured under one roof. Rimac Automobili’s extreme broadness of know-how and skill sets  opens an array of possibilities for chasing perfection on every level.

2016 Rimac Concept_One

The Concept_One continues the journey that the supercars with conventional drive have started.
Similar to today’s supercar classics, which marked an important part in automotive history, the Concept_One also began its life on a piece of paper. Starting from the first sketch to the hand-written mathematical theory of the Rimac All Wheel Torque Vectoring system down to the basic functions and the software code which brought it to life. Just like body panels of historical supercar legends were made by precise hits of a skilled hands to form sheet metal into beautiful shapes, an almost artistic manual process creates the Concept_One’s numerous components. From laying carbon-fibre, machining light alloy parts, tailoring the wiring loom, to the artistically woven interior while carefully finishing each unique part, the Concept_One represents the harmony of skills developed throughout the years of car making.

“The Concept_One represents the perfect symbiosis of modern technology developed here in our company and traditional automotive craftsmanship for which we have the utmost respect. We stay true to the roots of motorsport and old skills of car makers and engineers who created the automotive world which made a profound influence on us when we were children. Every single part of the Concept_One has been through a hand-finishing process and is carefully assembled at our facilities. We invest tremendous effort into developing the feeling which this car gives to the driver. Not only in terms of driving characteristic but also the feeling and the sound from the driver’s perspective. For example, 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. We wanted to achieve that solid feeling of classic supercars. The goal was to achieve a true connection between the driver and the machine – and that is only possible with passion, attention to details and craftsmanship. The Concept_One is a truly hand-made car.” said Mate Rimac.

In-house production
The ambitious goal Rimac Automobili set themselves is to produce as much as possible in-house. Painstaking attention to every detail requires high quality, which can best be maintained and controlled if the engineering and manufacturing teams are under the same roof.

Thousands of metal, electric and carbon fibre parts have to be manufactured, assembled and tested for each Concept_One. Even the tools, jigs and moulds are designed and produced by Rimac Automobili. Most of the parts start their lives as aluminium blocks or raw bare carbon fabrics which don’t leave the Rimac facilities in Sveta Nedelja before they are assembled into cars.

Battery pack
Electric vehicle batteries are usually challenged by capacity requirements. While it is challenging to develop a battery system that holds sufficient energy for an acceptable range, Rimac Automobili has faced an additional challenge: delivering 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. The result is a highly advanced high-performance battery pack that is designed for demanding track- use, high power delivery and safety.
Each of the 8450 battery cells is individually controlled through the in-house developed Rimac Battery Management System, which  ensures optimal conditions for a long battery life and long-term performance.

Rimac All Wheel Torque Vectoring
Conceived in a road car, perfected on the most demanding road in the world – the hill climb to Pikes Peak.

Rimac All Wheel Torque Vectoring system is designed and developed by Rimac Automobili and is currently the only system in the world with this principle available on a production car. The advantages of the R-AWTV over conventional drivetrains was most noticeable on the most demanding hill-climb race in the world – Pikes Peak Hill Climb 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 in 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.
Compared with a conventional powertrain with four-wheel drive where the torque on each wheel is controlled either by braking through a hydraulic braking system or cutting the power of the engine and thus the power on all four wheels, the Concept_One does not have to make any compromises.

2016 Rimac Concept_One

2016 Rimac Concept_One

R-AWTV can reduce or raise the torque on any wheel at any given moment, depending on the situation and driver input, without any limitations.
R-AWTV also increases safety as it can react faster and use the potential of each tire better than traditional stability systems. A dynamic “electric ABS” is moreover  included in the R-AWTV system.
The Concept_One’s regenerative braking system can slow the car down with up to 400 kW of regenerative braking energy or up to 0,6g of deceleration, without activating the carbon-ceramic brakes. R-AWTV can distribute the brake force smoother, faster and with greater precision than conventional ABS systems thus ensuring the maximum vehicle stability in cases of braking on surfaces at  different grip levels. Still, the driver can also chose to disable regenerative braking and use friction brakes only. The throttle-off regenerative braking function can be adjusted separately.
Depending on the wishes and driving skills of the driver, the R-AWTV can change the character of the car. The driver can choose between four driving modes: comfort, control, track and drift mode, or set-up a custom setting with customised power distribution, regenerative braking settings, etc. The R-AWTV can also be completely turned off.

The driver can choose the driving modes via knobs on the central console. Depending on the chosen mode the car will act differently on the limit of grip. It can tend to understeer, be neutral, or for the more experienced drivers, have a tendency to oversteer and thus enable more aggressive driving style through corners.

Rimac Automobili’s test driver Miroslav Zrnčević explains the endless possibilities that the Concept_One has to offer: “Thanks to its unique architecture and features, the Concept_One can use the maximum potential of the tires. Depending on the driver’s preferences and R-AWTV setup, it offers multiple cars in one. The Concept_One represents the pinnacle of technology and design that we can give as a company. Every unit carries its romantic story. Concept_One is a different driving experience. A car that gives a new dimension of driving experience.”

Rimac All Whell Torque Vectoring Video:

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. We wanted to achieve lightning-fast acceleration, and a top speed worthy of a true supercar. In order to meet those targets, we 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.

Limited production
The Concept_One will be produced in the total of eight units.

Rimac Automobili’s collaborate philosophy is to share ideas and technologies with other manufacturers in various industries to accelerate the shift to a more efficient and better transportation system. As a showcase of its main business, Rimac Automobili will, in addition, display its technologies and abilities that are available to other companies. A special edition of the Greyp G12S bike, made by Rimac’s sister company Greyp Bikes, will also be shown in Geneva.

    Mum, is the word on range. Weird.

    1. pvwowk says:

      You don’t buy a car like this because you want a long range electric.

    2. tftf says:

      About 300km (but this is likely a lenient Euro cycle number).

      I don’t think anyone buying (or rather able to buy) a hypercar cares too much about range.

      1. evcarnut says:

        Pretty amazing car. This technology will lead to more amazing breakthroughs . Got to give these guys a lot of Credit . They are some of the most brilliant students with nothing but passion & desire to succeed .. Got to keep watching these guys . I got a good feeling about what I see here . I have no doubt that they will make great advancements in EV Innovative breakthrough technologies…

        1. wavelet says:

          Good luck. Very low chance of anything realresulting here.

          If they’re only planning on making/selling 8, how exactly are they planning to fund any further R&D? And good luck to anyone buying one a.f.a. service goes…

          I’ll believe they cna actually make a production car when I hear they’ve sold & delivered it.

      2. Big Solar says:

        I thought the car had a 300ish mile range…..?

    3. tftf says:

      See this video at 8:30 and following for some numbers:

    4. Pushmi-Pullyu says:

      Joe said:

      “Mum, is the word on range. Weird.”

      For a car which has a top speed of 355 km/h (220.6 MPH), range is going to be extremely dependent on speed.

      As I recall, Top Gear’s track test of the Tesla Roadster (a few years back) indicated a (partially calculated) range of 55 miles at top speed, in a car that averages about 160-200 miles of range in real-world driving.

      But I suppose it would have been nice if they had given an estimated range for driving at, say, 60 MPH, on a pleasant day using neither cabin heater nor A/C. (That’s assuming it has a cabin heater and A/C… which may not be correct, since neither is mentioned.)

  2. tftf says:

    Hats off to this small and young company with only a few hundred people (apparently 150, soon 300 employees) for finally pulling this off.

    They wanted to make 88 cars by 2013 iirc. That’s how the car industry works, delays are the norm – especially for such a car.

    I hope they get enough return to continue making extraordinary stuff, the development projects for Koenigsegg should also help…

    http://koenigsegg.com/regera/

  3. Pushmi-Pullyu says:

    “Only eight units to be produced!”

    Well, that certainly gives new meaning to the term “limited production”!

  4. Someone out there says:

    A very interesting car but the battery is WAY too small. You will drain it in no time at all if you actually start to use it as a performance car. 82 kWh is good enough to drive around in a parking lot to impress your friends but not much more. It’ll barely take you one lap around any respectable racing course. You’ll probably be able to do a couple of 1/4 mile drags but not much more.

    It should have at least 200 kWh. It’s a million dollar car, they can afford – although maybe not fit it 🙂

    1. tftf says:

      Where’s the battery tech for that? Area 51 ;)?

      Have you seen how much the car weighs already with the current battery?

      1. Someone out there says:

        Sure, it’s not an easy problem to solve but making a sports car that can only be used as a sports car for 5-10 minutes is kind of pointless. They won’t find many customers for such a car. On the other hand, they are only making 8 of them. I doubt they would be able to sell many more even if they did produce them.

    2. Pushmi-Pullyu says:

      “Someone out there” said:

      “You’ll probably be able to do a couple of 1/4 mile drags but not much more.”

      That’s a bit of an exaggeration, innit?

      I’d guess that at a minimum it will be able to compete in the Pike’s Peak run. According to Wikipedia: “The track measures 12.42 miles (19.99 km) over 156 turns, climbing 4,720 ft (1,440 m) from the start at Mile 7 on Pikes Peak Highway, to the finish at 14,110 ft (4,300 m), on grades averaging 7.2%.”

  5. Scott says:

    Neat, but could I get a small electric pick up truck? That would be useful, thank you.

  6. Nick says:

    Surprised they didn’t make a deal with Tesla on charging.

    1. Sveno says:

      My thoughts too. I bet Mate and Elon would get along quite well and have respect for each others doings.

  7. Rick Bronson says:

    Waste of research money to design a car like this that can sell only 8 units.

    Please focus on making Model-S / Bolt like vehicle that can sell in 1000’s.

    1. tftf says:

      They do development work for other companies, see the video I linked above or read more about Rimac.

      But doing such a volume car by themselves isn’t realistic, they would probably be gone by now.

    2. JeffD says:

      Why should they focus on Model S or Bolt type cars when we already have those cars? No one ever told Lamborghini or Ferrari to make family cars. I think there is plenty of room for all kinds of electric cars.

  8. ffbj says:

    The most exclusive car rally on earth.

  9. Sveno says:

    “The term “production version” suggests to us that since unveiling of the concept in 2011, all the cars seen to date weren’t production, more like prototypes.”

    Mate has mentioned a few times that they had only one prototype of each iteration. Maybe not in english.

  10. SJC says:

    $1 million for this $600 thousand for the Mercedes SLS and maybe $300 thousand for the Audi R8e. They all are electric and all have four motors.
