<< Prev Page 2 of 2  The key to the Nevera’s exceptional performance is Rimac’s pioneering electric powertrain. Every component of the Nevera’s electric powertrain has been exhaustively reworked since its inception to deliver more torque, greater performance and enhanced efficiency.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. This helps create an excellent 48/52 front/rear weight distribution and the best possible handling balance. Developments of the advanced battery cooling system have made it even more efficient since the introduction of the C_Two, enabling more power to be delivered for greater periods. Four bespoke surface-mounted permanent magnet motors drive the Nevera’s four wheels individually. Together, they enable 1914hp and 2360Nm of torque, which is triple the output of a ‘conventional–engined’ supercar. The front and rear wheels are each connected to a pair of single-speed gearboxes. Capable of instantly summoning maximum torque from the first moment, the Nevera's electric motors are 97 per cent efficient – compared with 40 per cent for the most effective internal combustion engines – and completely maintenance-free throughout their operating life. With the ability to sprint to 60mph in 1.85 seconds and continue the acceleration all the way to a 412 km/h (258mph) top speed, the Nevera opens up a new dimension in hypercar performance. Accelerating from rest to 161 km/h (100 mph) requires just 4.3 seconds and it maintains its eye-widening acceleration throughout a full-throttle cycle, achieving 186mph (300 km/h) from rest in 9,3 seconds, shredding a whole 2,5 seconds from the initial targets. Finally, it achieves a record-breaking 8,6 seconds quarter-mile time. Rimac's All-Wheel Torque Vectoring 2 (R-AWTV 2) system replaces traditional Electronic Stability Program and Traction Control systems to further bolster grip and traction. Meanwhile, the Nevera's R-AWTV 2 system enables infinitely variable dynamic responses to road and track conditions by calibrating the amount of torque supplied to each wheel. R-AWTV 2 calculates the precise level of torque to channel through each wheel for ultimate stability and exceptional agility. Both predictive and responsive, R-AWTV reads the road and makes over 100 calculations per second to tailor the level of torque to achieve the desired driving style. “Our torque-vectoring enables new level of drivetrain calibration,” explains Miroslav Zrnčević, Rimac Test and Development Driver, and depending on the driving mode selected, the R-AWTV 2 technology can enable the Nevera to be drifted sideways or provide optimum levels of all-wheel-drive grip, traction and safety – no matter how challenging the road and weather conditions.Thanks to a four-individual-motor drivetrain, the driver can also change the torque distribution, and personalize the performance delivery even further, for a completely bespoke drive – ranging from front to rear wheel drive biased car.” The Nevera is also equipped with cutting-edge braking technology. A complex electro-hyrdaulic 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. This enables the Nevera to make the highest use of regenerative braking of any other car on the market now. 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 callipers. Combined they provide consistent, fade-free and exceptionally powerful braking, even when the car is subjected to extreme forces on the track. Double wishbone suspension with electronically controlled dampers and active ride height adjustment provides a combination of a smooth and comfortable ride, exemplary body control and ultra-agile handling. Further emphasising Rimac’s technology-first approach, the Nevera utilises the very latest electric power steering with steer-by-wire function, enabling adaptive driver-feedback, depending on the drive mode. Additionally, it works as a drive-by-wire system when in Driver Coach mode to demonstrate optimum racing lines and vehicle control to the driver. Rimac’s versatile and responsive R-AWTV 2 system enables drivetrain calibration for the Nevera to facilitate any driving style through seven different driving modes. For a truly engaging drive on the road, SPORT mode sharpens the response of the throttle, brakes, suspension and steering, while DRIFT mode supplies more torque to the rear wheels to accentuate oversteer and help hold the car in a controlled power slide on the track. COMFORT mode strikes a perfect balance between a relaxing ride, efficiency and driving pleasure, while RANGE mode enables the Nevera to achieve maximum mileage from each battery charge. In expert hands, TRACK mode sets the Nevera to full, unrestrained configuration to help drivers exploit the car’s full potential. Finally, two CUSTOM modes enable drivers to access their personal, pre-selected performance characteristics. To enable drivers of all abilities to extract maximum performance from the Nevera and help them further develop their track driving skills, Rimac has developed the world's first AI (Artificial Intelligence) Driver Coach. Adding a new, immersive dimension to the driving experience, Nevera’s Driver Coach evaluates performance and provides guidance to optimise and enhance the driver’s on-track performance. By accessing 12 ultrasonic sensors, 13 cameras, 6 radars, and the very latest NVIDIA Pegasus operating system, the Rimac Driving Coach adds an additional, immersive experience behind the wheel. The system overlays selected race circuits in real-time, offering clear and precise audio and visual guidance, to enable drivers to perfect their racing lines, braking and acceleration points and steering inputs. The Driver Coach feature will become available in 2022 and launched via over-the-air upgrades to already delivered Nevera cars whose hardware is ready for this unique feature. With space for two occupants in full race regalia and their luggage, Nevera is as much a capable grand tourer as it is a performance hypercar. Digital screens soak up needless toggles and switches, leaving only essential tactile controls, giving more space to enjoy Nevera’s carefully designed interior. The cockpit features a trio of high-definition TFT screens, which present as much, or as little, information as the user requires. Configured for both track driving and comfort, the layout of the cockpit is divided into two zones. The focus of the top segment is entirely placed on driving pleasure and performance, while the lower part houses the infotainment system, comfort controls and driving data. Tactile billet aluminium rotary controls and switches - including three displays with rotating control - provide a resolutely analogue feel, tailored to enable the driver to utilise the cutting-edge digital technology in an even more engaging manner. From the cockpit, the driver can monitor every aspect of the car’s performance with real-time telemetry - downloadable to a laptop or smartphone for later review. Rimac M2M system delivers a wealth of real-time data to the manufacturer as well as the owner. While the user is connected to the vehicle through our intuitive mobile app, the manufacturer receives anonymised performance data. Using intuitive mobile applications developed in-house at Rimac, Nevera owners can track live data, such as GPS location, charging speed and battery status while also using it to analyse driving performance, metrics and map previews on Android & iOS. No two Neveras will leave the Rimac factory looking the same or bearing the same specification, thanks to customers’ ability to choose from a comprehensive range of bespoke trims and material options. In addition to the company’s premium individual personalisation program, Rimac will offer its flagship in various editions: GT, Signature, Timeless or the customers can choose to go Bespoke. As part of the customer journey, each Nevera owner will be invited to Croatia to design his or her car to their exacting requirements. The Nevera itself will be exclusively available through Rimac’s global dealer partners network, taking in 19 sites and many of the world’s major cities across Europe, North America, Latin America, Europe, Middle East and Asia. << Prev Page 2 of 2 |
