Ferrari Roma

The Roma is powered by the award-winning Ferrari type F154 engine. It is a 3.9 litres (3,855 cc), turbocharged, 90 degree V-8, dual overhead cam (DOHC) design. The Roma's type 154BH is rated at 456 kW; 612 hp (620 PS) between 5,750 and 7,500 rpm and 761 N⋅m (561 lb⋅ft) of torque between 3,000 and 5,750 rpm.

Ferrari Roma Type 154 Engine

The forced induction air intake system uses twin parallel water cooled turbochargers and two air-to-air intercoolers. The dry sump lubrication system helps prevent oil starvation during high g-force operation.[12]

The engine is mated to the new 8-speed dual-clutch F1 transmission shared with the SF90 Stradale. This new unit translates into more acceleration in the intermediate gears with an extended tall top gear for motorway cruising. Ferrari says there is 15 percent more longitudinal pull in third gear when compared to the previous generation's 7-speed unit.[13] The transaxle is equipped with an electronic differential and a mechanical reverse gear which contrasts to the SF90's electric motor reverse. This design weighs 6 kg (13 lb) less than the 7-speed unit used in the Portofino and is claimed to provide quicker and smoother shifting. Much of the weight savings is due to the dry sump design and the primary alloy oil case that is compact and wrapped tightly around the various engine components.[14]

The double wishbone, coil spring design with anti-roll bars also has an optional MagneRide dynamic shock absorber system that provides more compact and controlled vehicle operation using magnetorheological dampers.

The Roma comes standard with Ferrari's F1-Trac traction control, side-slip control 6.0 technology, electronic stability control (ESC), launch control (Power Start), and the Ferrari Dynamic Enhancer. It also has a five-position Manettino dial on the steering wheel, allowing selection of the vehicle's driving mode between wet, comfort, sport, race, and ESC-off.

The Roma's electronic interior cockpit controls also represent a major deviation from recent Ferrari road cars. The human-machine interface (HMI) is largely a digital touch-screen control system (using Haptic technology) that is also shared with the SF90 Stradale. The touch-screen control extends to some functions on the steering wheel.

Some driver assistance systems (ADAS), like front and rear radar with adaptive cruise control, are also available as options to aid during long drives.

The Roma was engineered to weigh 200 kg (441 lb) less than the Portofino while being based on the same platform. This was achieved through a more rigid body structure and the overall use of lighter parts. Ferrari claims that 70 percent of the parts used on the Roma are new as compared to the Portofino. With the lightweight components, the car's dry weight is 1,472 kg (3,245 lb). Its curb weight (without the driver) is 1,570 kg (3,461 lb). The published weight distribution is 50% front to 50% rear.[15]

The dynamic rear wing self-activates at high speed to help the vehicle generate downforce. The wing's three positions are low drag (flush (0–100 kph), medium downforce (100–300 kph), and high downforce (100–300 kph cornering and braking). The maximum deployment is rated at 95 kg (209 lb) of downforce at 250 km/h (155 mph). The rear spoiler is complemented by a pair of underbody vortex generators that create a ground effect and manage the wake of the front wheels to ensure efficient load management.[16]

20-inch cast aluminum wheels are standard, with 20-inch forged alloy wheels as an option. Front wheel rims are eight inches wide, and rear rims are ten inches. The tires used on the Roma measure 285/35 ZR20s at the rear and 245/35 ZR20s at the front. The model was introduced with the Ferrari-approved choice of Pirelli, Michelin, or Bridgestone run-flat tires.

The Roma has 390mm front and 360mm rear carbon-ceramic ventilated disc brakes. The Ferrari Dynamic Enhancer controls the yaw angle by actuating the individual brake calipers of the car, a first for a Ferrari GT model.

A redesigned exhaust system uses particulate filters (similar to diesel particulate filters) for emissions regulation. This was achieved by removing the silencers (mufflers) and adding bypass valves. It has been engineered to retain, enhance, and expand the engine's exhaust notes while reducing particle emissions.

The Roma's published top speed is > 320 km/h (199 mph). Performance figures include a 0-100 km/h (62 mph) acceleration time of 3.4 seconds and a 0-200 km/h (124 mph) acceleration time of 9.3 seconds. The Roma's dry weight-to-power ratio is best in class at 2.37 kg/cv (5.3 lb/hp).[14][17][18][19]

Ferrari Roma Performance

The Roma's minimum height off the ground is a static 4+34. Its maximum front ramp angle is 11 degrees, and the maximum rear ramp angle is 15 1/2 degrees.

The vehicle comes with 10 cubic feet of boot space in the trunk and additional storage space behind the two front seats. An option of foldable seat backrests expands the storage configuration to 14 cubic feet. Keeping with the car's grand touring theme, and as with certain additional models, the Roma can be ordered with a specially designed, multi-piece luggage set that fits into the vehicle's rear trunk. The luggage matches the interior leather.

The Ferrari Roma Spider retains the coupe's design with a soft top that deploys in 13.5 seconds at speeds up to 37 mph. The redesigned active rear spoiler adjusts for top-down driving, while chassis reinforcement adds only 185 pounds compared to the coupe.

The Ferrari Roma Spider's cabin retains the original Roma's design, featuring an 8.4-inch touchscreen and a metallic gear selector surrounded by luxurious materials. Improved steering wheel buttons and a glowing red start button have been added for enhanced usability. To minimize wind noise and turbulence, a 5-mm aerodynamic element and a wind deflector (activated by rotating the rear seat backrest) have been incorporated. The wind deflector is not functional with rear passengers seated, but the limited rear space makes this a minor concern.

The Roma Spider houses a turbocharged 3.9-liter V-8 engine, generating 612 horsepower and 561 pound-feet of torque, delivered to the rear wheels via an eight-speed dual-clutch automatic transmission. Ferrari has made minor adjustments to the gearbox for enhanced fuel efficiency, and the Roma Spider features the latest Slide Slip Control system for optimal traction, stability control, and predictable drifting capabilities.
