Ferrari Roma: Which Version to Buy and Why

The Ferrari Roma catalogue contains two entries named 3.9 DCT within a single generation. Their engine, drivetrain, performance, fuel-consumption and chassis specifications are identical; the only recorded difference is kerb weight. One 3.9 DCT weighs 1,472 kg, while the other weighs 1,556 kg.

The Ferrari Roma catalogue contains two entries named 3.9 DCT within a single generation. Their engine, drivetrain, performance, fuel-consumption and chassis specifications are identical; the only recorded difference is kerb weight. One 3.9 DCT weighs 1,472 kg, while the other weighs 1,556 kg. That 84 kg difference makes the 1,472 kg 3.9 DCT the stronger choice when comparing power-to-weight figures alone. The data provides no prices, equipment lists or reliability measurements, so it cannot show whether the heavier entry offers anything in return for its additional weight.

Ferrari Roma generations and versions

The Ferrari Roma has 1 generation in the supplied catalogue. The 1 generation started on 2019-11-01, has no recorded end date, and uses the Roadster body type. It contains 2 modifications, both named 3.9 DCT and both rated at 620 hp. Because the two versions have the same name and power output, kerb weight is the clearest way to distinguish them: 3.9 DCT — 620 hp, 1,472 kg and 3.9 DCT — 620 hp, 1,556 kg.

There is no second generation to compare, and the data records no restyling. Therefore, the buying decision is not about choosing between generations or engine families. It is a comparison between two otherwise matching catalogue entries with different kerb weights.

Ferrari Roma engine and specs

Both 3.9 DCT versions use a front, longitudinal engine with direct injection. Each engine has 4 valves per cylinder, a 9.45 compression ratio, and an 86.5 × 82 mm bore-and-stroke specification. Peak power is produced across 5,750–7,500 rpm, while maximum torque is available across 3,000–5,250 rpm.

Engine output does not separate the two versions. Each produces approximately 160.8 hp per litre, calculated from 620 hp and 3.855 litres. Torque output is approximately 197.1 Nm per litre, calculated from 760 Nm and the same displacement. Since these figures are equal, neither version offers an advantage in engine output per litre.

Ferrari Roma performance and fuel economy

The recorded performance is identical: both 3.9 DCT versions reach 100 km/h in 3.4 seconds and have a 320 km/h maximum speed. No other acceleration measurements are provided, so they are not measured in this dataset.

Fuel consumption also gives no reason to prefer one version. Each is listed at 17.8 L/100 km in the city, 10.8 L/100 km on the highway and 11.2 L/100 km combined. The city figure is 7.0 L/100 km higher than the highway figure and 6.6 L/100 km higher than the combined figure. Both versions emit 255 g/km of CO₂ and meet the Euro 6 classification.

Although the lighter version has a better calculated power-to-weight ratio, the supplied acceleration, top-speed and fuel-consumption figures do not show a measurable advantage. Buyers should therefore treat the weight difference as a specification distinction, not as proof of quicker recorded acceleration or lower recorded consumption.

Ferrari Roma dimensions, weight and wheels

Full exterior dimensions are not measured in the supplied data. Gross weight is also not measured for either version.

Both 3.9 DCT versions have 100 mm of ground clearance and an 80 L fuel tank. Their listed wheel sizes are 245/35 R20 and 285/35 R20. Both use Independent, spring suspension at the front and rear, Ceramic ventilated front brakes, and Disc ventilated rear brakes.

Weight is the sole recorded dimensional difference. The 1,472 kg version is 84 kg, or about 5.4%, lighter than the 1,556 kg version. Its weight-to-power figure is approximately 2.37 kg per hp, compared with approximately 2.51 kg per hp for the heavier entry. Expressed the other way, the lighter version delivers approximately 421.2 hp per tonne, while the heavier one delivers approximately 398.5 hp per tonne—a difference of about 22.7 hp per tonne.

Ferrari Roma problems and reliability

Problems and reliability are not measured in the supplied data. There are no figures for failure rates, repair frequency, service costs or component life. The two 3.9 DCT entries also share the same listed engine, gearbox, drive, suspension and brake specifications, so this catalogue cannot establish a reliability advantage for either one.

Which Ferrari Roma 3.9 DCT should you buy?

Choose the 3.9 DCT — 620 hp, 1,472 kg if the decision is based strictly on the supplied numbers. It retains the same 620 hp, 760 Nm, 3.4-second acceleration figure, 320 km/h maximum speed, 8-speed Robotic gearbox and RWD configuration while carrying 84 kg less kerb weight. Its calculated 2.37 kg per hp is preferable to the heavier version’s 2.51 kg per hp.

Choose the 3.9 DCT — 620 hp, 1,556 kg only if information outside this dataset identifies equipment or another feature that justifies the added weight. The catalogue provides no price or equipment data, so what any extra money buys is not measured. On the available evidence, the heavier entry offers no additional power, torque, speed, fuel capacity, ground clearance or recorded performance.

The numerical verdict is therefore straightforward: the 1,472 kg 3.9 DCT has the better power-to-weight specification, while every other supplied comparison ends in a tie.
