<< Prev Page 3 of 3  The architecture of the Fenomeno features the mid-mounted, naturally-aspirated 6.5-liter V12 engine combined with three electric motors, one of which is integrated within the new eight-speed dual-clutch gearbox. The power output of the oversquare V12 engine is 835 CV at 9250 rpm, thanks to the redesigned valvetrain which supports a maximum engine speed of 9,500 rpm. The specific power is over 128 CV per liter, the highest in the history of Lamborghini V12 engines; the maximum torque is 725 Nm at 6750 rpm, with 80% of the torque already available at 3,500 rpm. The drive to the four wheels is provided by the internal combustion engine that delivers traction to the rear wheels, and by the pair of electric motors installed on the front axle, while the third radial flux electric motor positioned above the gearbox provides torque to the rear depending on the selected driving mode. The combined torque from the four units offers levels of performance that are unique even among super sports cars, with 725 Nm available from the engine and 350 Nm from each of the front electric motors. The same goes for the total maximum power output, which reaches 1,080 CV thanks to a further boost in power provided by the new 7 kWh battery adopted specifically for the Fenomeno. The two front e-motors are oil-cooled axial flow models and offer an exceptional weight-to-power ratio: 110 kW for each unit, which weigh just 18.5 kg each. As well as driving the front wheels, they also provide a torque vectoring function to optimize the driving dynamics, as well as providing the regenerative braking function. The Fenomeno adopts an eight-speed dual-clutch gearbox installed transversely behind the longitudinal V12, leaving space under the tunnel for the lithium-ion battery that powers the electric motors. This layout allows the final weight to be kept low, as well as making the footprint more compact. The eight-speed dual-clutch gearbox is the perfect solution for driving at the highest levels of sports performance, thanks to its lightning-fast shift times. What’s more, the addition of an eighth gear allows fuel consumption to be optimized as well as maximizing comfort while cruising. The continuous downshift function, which allows the driver to shift down multiple gears at once simply by keeping the left shift paddle held in, is also notable; this allows the driver to engage the ideal gear on the basis of their instantaneous speed during braking, for a sensation of total control. Located above the gearbox this electric unit provides the functions of starter motor and generator, as well as providing energy to the two front electric motors via the battery located under the tunnel. It delivers the boost function in 100% electric driving mode and allows zero-emission four-wheel drive motoring by driving the rear axle directly. Its role varies depending on the engaged driving mode, making use of a decoupling mechanism. For this reason, it is equipped with a dedicated synchronizer that allows connection to the dual-clutch gearbox. When supporting the V12 engine, the e-motor is in position P3 with electric motor downstream of the gearbox, shifting to P2 to recharge the battery when stationary or at low speeds. In P3, the Fenomeno can operate as a full EV, depending on the selected driving mode, confirming the four-wheel drive tradition of Lamborghini super sports cars even when it comes to zero-emissions driving. The increased power and performance required the braking system to be designed from the ground up, to ensure the necessary levels of toughness and durability combined with exceptional stability in braking. Fenomeno adopts the innovative CCM-R Plus carbon-ceramic brake system, similar to technology in LMDh race car brakes such as those on the SC63, and bringing racing-level performance to the road. The brake disks are manufactured in a 3D structure with long carbon fibers incorporated in a carbon matrix and coated with a treatment developed specifically for this project. This not only allows the service life of the disks to be increased, but also offers an improved coefficient of friction, providing maximum braking stability, durability and reliability. This allows for extreme performance in any condition, with unprecedented consistency and response stability. The system is further enhanced by the meticulous design of the car’s entire aerothermal concept, maximizing airflow to both discs and calipers for optimal cooling efficiency. To deliver perfect driving dynamics and ensure the vehicle is as fun to drive as possible, Fenomeno adopts racing shocks that can be manually calibrated to allow the perfect stance and setup to be achieved for the track and type of use. They also offer optimum damping performance that keeps body movement in check, as well as greater travel ratio between wheel and shock to ensure the shock absorber is working as precisely as possible. The result is suspension kinematics that allow the shocks to work at their best and therefore offer extraordinary sports driving behavior. Management of vehicle dynamics is entrusted to a series of specific components. At the heart of Fenomeno’s integrated control system is the 6D sensor coupled with innovative vehicle dynamic control logics, introduced on a Lamborghini for the first time. The 6D sensor is installed strategically close to the vehicle’s center of gravity and is directly connected to the IPB (Integrated Power Brake) control unit. Its function is to provide measurements of the acceleration on all three axes (lateral, longitudinal and vertical) in real time, as well as the angular velocity also for all three axes (pitch, roll and yaw). This information allows for a highly-precise estimation of the vehicle’s speed, the side-slip angle and the instantaneous coefficient of friction between tires and road surface. The 6D sensor is part of the provision of the IVE (Integrated Vehicle Estimator), whose calculation process uses Kalman filtering. This is an algorithm which, more specifically, provides a predictive dimension of the vehicle's dynamics, thus allowing all related systems to adapt to any driving situation. These systems include the IBC (Integrated Brake Controller) which implements wheel slipping control functions during braking, reducing stopping distances up to 10%. The direct connection to the IVE allows the IPB system to increase braking performance on bends and in typical situations found during track driving, such as passing over curbs. All this is based on the accurate estimates produced by the IVE thanks to the 6D sensor. Bridgestone, a world leader in premium tyres and sustainable mobility solutions, is the exclusive tire partner for the Fenomeno, equipping the new super sports car with custom-engineered Bridgestone Potenza premium tyres. As Official Technical Partner of Lamborghini, Bridgestone has developed bespoke Potenza Sport ultra-high-performance tires for the Fenomeno to ensure optimum dynamism from the most powerful V12 engine ever produced by Lamborghini. Available in 265/30 ZRF21 (front) and 355/25 ZRF22 (rear) sizes, these premium tyres offer exceptional high-speed performance, excellent steering response and precision to best manage the few-off's 1,080 CV powertrain. These custom tyres are available with Bridgestone's Run Flat Technology (RFT), which allows the driver to continue driving safely at 80 km/h for 80 km after a puncture, even with pressure at zero. The Lamborghini Fenomeno will also be available with high-grip, semi-slick bespoke Bridgestone tyres offering track-level performance while remaining fully homologated for public roads. Custom-engineered to allow the vehicle’s performance potential to be fully exploited, the track-oriented fitment developed for the Fenomeno will be available in 20 and 21-inch sizes. These premium tyres have been created using Bridgestone’s proprietary Virtual Tyre Development technology, which allows for significant reductions in the use of raw materials and emissions throughout the tire development process. << Prev Page 3 of 3 |
