Rimac Automobili revealed an all-electric, 1914hp, 258mph, €2m hypercar today. The Nevera is the production-ready iteration of the Rimac C_Two concept car, which was revealed at the International Geneva Motor Show in 2018.
Rimac has also created numerous new innovative active aerodynamic elements to elevate the Nevera’s cooling, performance, stability, and efficiency abilities. The front bonnet profile, underbody flap, rear diffuser and rear wing can each move independently, driven by complex algorithms that provided the optimum aerodynamic configuration for every driving situation. Switching from ‘high downforce’ to ‘low drag’ mode reduces aerodynamic drag by 17.5 per cent to create a 0.3 coefficient of drag. Lightweight, forged alloy wheels feature an aerodynamic design that channels cooling air to the Brembo carbon-ceramic braking system.
Nevera’s monocoque, developed by the former C_Two Chief Engineer Daniele Giachi, includes a bonded carbon roof, integrated structural battery pack and rear carbon subframe. Weighing less than 200kg and utilizing 2200 carbon fiber plys and 222 aluminum inserts, the monocoque encases the car’s battery to form a compact structure.
The unique H-shaped, liquid-cooled, 120kWh, 6960-cell battery was designed from scratch by Rimac and sits at the very heart of the Nevera. Capable of producing 1.4MW of power, the Lithium/Manganese/Nickel battery also forms an integral part of the car’s core, adding 37 per cent structural stiffness to the carbon fibre monocoque. The battery’s optimum positioning low and central within the car’s floor contributes to an ultra-low centre of gravity.
Rimac’s All-Wheel Torque Vectoring 2 (R-AWTV 2) system replaces traditional Electronic Stability Program and Traction Control systems. Meanwhile, the Nevera’s R-AWTV 2 system enables variable dynamic responses to road and track conditions by calibrating the amount of torque supplied to each wheel. R-AWTV 2 calculates the level of torque to channel through each wheel for stability and agility.
The Nevera is also equipped with cutting-edge braking technology. A complex electro-hydraulic brake booster with brake pedal feel simulator distributes the braking force between the friction brakes and electric powertrain, depending on the battery, powertrain and brake state. For instance – it dissipates kinetic energy through the friction brakes if the battery is close to its thermal limits, or activates more regenerative braking in case the friction brakes are hot. All those transitions should remain in the background, not noticeable to the driver. In addition to a maximum range-enhancing regenerative braking of 300 kW provided by the electric motors, substantial stopping power comes from 390 mm Brembo CCMR carbon-ceramic brake discs and six-piston calipers.
