Ferrari Roma test drive: technical and mechanical details - preview

Ferrari Roma engine

La Ferrari Roma Powered by a 8 hp turbocharged V620 engine from a family that has won the Engine of the Year award four years in a row. The main innovations of this version of the Ferrari V4 engine are new camshaft profiles, a speed sensor that measures the rotation of the turbine, which allows the maximum speed to be increased to more than 8 rpm. and the introduction of a gasoline particulate filter, a closed-matrix filter designed to comply with Euro 5000D European pollution control legislation.

Exchange

The new 8-speed dual-clutch transmission, optimized in terms of overall dimensions and 6 kg lighter than the previous 7-speed gearbox, reduces fuel consumption and increases the pleasure of driving Ferrari Roma in urban conditions and during Stop & Go maneuvers. ., and also makes gear shifting more dynamic and exciting during sporty driving thanks to the use of low viscosity oil and a dry sump configuration to minimize losses in hydrodynamic efficiency.

In addition, this oil bath dual-clutch transmission comes from the all-new transmission featured in the SF90 Stradale; in this version, however, it can count on a longer gear ratio and reverse gear, which in the SF90 Stradale is driven by an electric motor. The overall dimensions of the new clutch assembly have been reduced by 20% and the transmitted torque has been increased by 35%. Powertrain software strategies have been improved with a more powerful ECU and tighter integration with the engine management program. Thus, gear changes are faster, but above all smoother and more uniform. According to Ferrari, the engine's near-instantaneous response to accelerator pedal pressure is due to its flat shaft, which guarantees greater compactness and mass containment, thereby improving hydrodynamics; small size of turbines, less subject to inertial forces; double scroll technology that reduces interference between cylinders; and to a one-piece exhaust manifold equipped with uniformly sized ducts to optimize turbine pressure waves and reduce pressure drops.

electronics

La Ferrari Roma it is equipped with Variable Boost Management, a proprietary software that modifies the transmitted torque according to the gear used, which gives the car continuously increasing traction, optimizing fuel consumption. As the gear ratios increase, the available torque increases to 760 Nm in 7th and 8th gears: this allows longer gear ratios in high gears, which is beneficial for lower fuel consumption and emissions while increasing torque curves torque in lower gears for constant thrust.

sound

Additionally, Ferrari RomaLike all previous Prancing Horse cars, it features a unique and unmistakable sound. To achieve this goal, several techniques were studied, including a new geometry of the exhaust line by eliminating the two rear mufflers, which significantly reduced the back pressure on the tail sections; new geometry of the wastegate valves, which are now oval in shape to significantly reduce exhaust back pressure and improve sound quality; and controlling the aforementioned “proportional” type bypass valves continuously and gradually in accordance with the driving situation.

Ferrari Roma chassis

Dynamic development Ferrari Roma focused on maximizing concepts fun to drive and ease of driving thanks to significant weight savings and the latest version concept Side slip control. The body and chassis of the Ferrari Roma have been redesigned using the latest bleaching techniques and the most advanced manufacturing techniques, bringing the percentage of completely new components to 70%, and the Ferrari Roma is a front- and mid-engined car. with the best weight / power ratio in the segment (2 kg / hp).

Side Slip Control 6.0

La Ferrari Roma equipped with 6.0 side sliding system, concept which coordinates the intervention of vehicle control systems through the use of a special algorithm. SSC 6.0 includes E-Diff, F1-Trax, SCM-E Frs and Ferrari Dynamic Enhancer systems, among others. The aim of the 5-position Manettino (Wet, Comfort, Sport, Race, ESC-Off) is to maximize the handling and traction of the Ferrari Roma over the already superior offering that the basic mechanical setup of the vehicle provides, which makes driving extremely fun.

Ferrari Dynamic Enhancer

Системы Ferrari Dynamic Enhancer, active only in the Manettino racing position, it controls lateral dynamics by creating precise hydraulic pressure according to the dynamic braking situation of each of the four wheels. FDE is not a stability control system and is linked to traditional electronic stability control: compared to the latter, it is designed to maximize driving pleasure by making it easier to control vehicle dynamics with a calibrated action. on the brakes of one or more wheels. This supports the goal of the racing car, namely driving pleasure and driving pleasure.

The ADAS

Advanced systems are also available upon request. ADAS Ferrari driving assistance systems (SAE level 1), such as adaptive cruise control, which can be activated directly from the steering wheel for everyday use or for long journeys in complete comfort, and autonomous emergency braking, lane departure warning with traffic sign recognition , Blind Spot Detection systems with rear cross traffic alert and surround view camera. The optional matrix LED headlamp system is designed to improve road visibility by using high beams, avoiding annoying vehicles both in your own direction and in the opposite direction. When a vehicle is detected in the light beam, the system selectively and automatically turns off parts of the beam that could blind the driver of another vehicle, forming a shadow cone. If the number of detected vehicles is high, the high beam can be turned off completely to partially or completely re-activate when the road is clear. On high-speed roads, the system prevents glare from vehicles coming from the opposite direction. In the presence of reflective traffic signs, the system can reduce the brightness of individual LEDs to make driving more comfortable. Another interesting feature of the Matrix LED headlights is the ability to adapt the dipped beam light beam to suit the driving situation.

Ferrari Roma, aerodynamics

In order to provide the best aerodynamic performance and at the same time maintain the stylistic purity of Ferrari Roma, various advanced technological solutions have been studied, most notably the use of a movable rear wing integrated into the rear window. which is designed to preserve the elegance of the closed wing lines and guarantee, thanks to automatic opening at high speeds, the level of aerodynamic load required for an exceptional performance vehicle.

Aerodynamic load

The synergy and day-to-day collaboration between Aerodynamics and Centro Stile has resulted in solutions suitable for creating the vertical load typical of sports cars without compromising design purity. The Ferrari Roma develops 95 kg more downforce at 250 km / h compared to another 2+ model, the Ferrari Portofino, through the use of vortex generators installed on the front underbody and active aerodynamics at the rear. The former are tasked with generating sufficient front load with a slight increase in resistance, while the automatically activated movable rear spoiler is directed to aerodynamically balancing the car by creating a load on the rear axle.

Active wing

Thanks to the special kinematics, the movable rear wing can assume three different positions: Low resistance, Average downforce e High downforce... In the LD position, the movable element is aligned with the rear window and allows air to pass over it, becoming invisible to the flow. When fully open (HD), the moving element rises at a 135 degree angle to the rear window, applying approximately 95 kg of vertical load at 250 km / h with a drag increase of only 4%. In an intermediate position (MD), the movable wing instead generates about 30% of the maximum vertical load with less than 1% increase in drag. The kinematics are driven by an electric motor, the logic of which is based on speed, longitudinal and lateral acceleration. In low speed conditions, when the contribution of vertical load to vehicle performance is small, the wing automatically adjusts to the Low resistance... This configuration is maintained up to 100 km / h. Above 300 km / h, the wing assumes a medium downforce position: in extreme driving conditions, it is preferable to have a more balanced car, taking into account also the minimum drag losses. Even in the intermediate speed range, in which the vertical load is paramount, the spoiler assumes the MD position: however, in this case, its movement will depend on the vehicle's longitudinal and lateral accelerations. The position of the movable wing can never be manually selected: its response threshold varies and is related to the position of the Manettino. This choice stems from the desire to harmonize vertical load generation and dynamic vehicle handling. Under appeal When braking quickly, the moving element automatically switches to HD configuration, creating maximum vertical load and making the vehicle aerodynamically balanced.
