BEHIND THE SCENES OF RIMAC ENGINEERING

Almost all cars are based on something - an existing platform, powertrain, electrical architecture or something else. With the C_Two, we started from the ground up and tailor-made all systems and components, which gave us an incredible freedom to optimise all aspects of the car to the last detail.

Mate Rimac / CEO of Rimac Automobili

We are very proud to develop, engineer and produce key systems and components of the C_Two in-house at our facilities in Croatia. Our hardware, combined with proprietary software are the ingredients that make our cars stand out and set new levels of performance.

Take a look behind the scenes of globally homologated electric hypercar design, engineering and testing. Find out what it takes to bring this car to the roads worldwide. Check back for more updates as the project progress.

Vehicle Engineering: Structural Analysis

Very few hypercars go through the fully-fledged homologation process. Taking up to four years to complete - from initial concept to cars on the road - there are no short cuts, just hard work, thousands upon thousands of hours of analysis and rigorous crash testing.

Aerodynamics

Featuring some of the most advanced aerodynamics on a road-legal production car, the C_Two showcases our unparalleled understanding of automotive airflow and active aerodynamic elements control. The aerodynamic concept is designed with different requirements in mind: cooling of the battery and powertrain systems, efficiency, downforce, aerodynamic balance and more. Discover how we achieved our targets.

Vehicle dynamics

Our team of vehicle dynamic specialists and simulation engineers combines inputs from all vehicle systems - torque vectoring, steering, brakes, battery, powertrain, aerodynamics, and others - to create a new level of driving dynamics enabled by the capabilities of a 4-motor electric hypercar architecture. Countless virtual iterations and thousands of simulations have been performed before we put our designs into metal and carbon. Then, we perform countless tests on tracks, roads, and testing equipment around the world. By repeating the process exhaustively, we produce efficient vehicles with unmatched performance, ride, and agility.

Tires

Tires are a critical component of every car. Forming the only physical link between the road surface and the vehicle, it is essential to equip our vehicles with the best performing tires available. Tested and developed through our own rigorous programme, we design bespoke tires in partnership with Pirelli to handle the most extreme performance in all conditions.

Torque Vectoring

Torque vectoring is a unique method of power distribution, which splits torque between each of a vehicle's wheels. Rimac's All-wheel Torque Vectoring (R-AWTV) is the centrepiece of our suite of homegrown technologies, giving our cars greater agility, stability and control.

Driver Coach

Our in-house developed Driver Coach is where advanced AI and real-world driving come together. Featured on the C_Two, Driver Coach is a personal in-car performance aid to help the driver utilize the car's full potential, optimise performance and create new levels of driving excitement.

Inverter development

The inverter converts direct current (DC) from the battery to alternating current (AC) that's supplied to the motor. Rimac's BFI (Big Fabulous Inverter) is the world's most power-dense inverter.
Our in-house team is designing all the hardware (electronic boards and the high-voltage components) and the software.

Gearbox development

The performance, mass and dimensional requirements could only be met by developing the components from scratch.
