Race simulation at real speed
CONFIDENCE 95%The Model S reaches 100 km/h first (3.33 s vs 3.43 s), but the Roma is ahead at every metre of the race. Explanation: the Roma accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Tesla Model S P85D is faster at 0-100 km/h, but the Ferrari Roma compensates at high speed thanks to higher peak power or top speed. At 400 m, Ferrari Roma leads by 0.50 s.

Model S P85D vs Roma: chronicle of a drag race at 357 km/h
The launch: 0 to 100 km/h
Off the line, the Model S P85D hits 100 km/h in 3.33 s versus 3.43 s for the Roma. The instant torque of 931 Nm from the electric motor makes the difference. At this point, the Model S P85D leads by 0.10 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Roma is doing 182 km/h against 167 km/h for the Model S P85D. The gap is 0.14 s. The gap remains stable from the start.
At 400 metres standing start, the Roma crosses the line in 10.68 s versus 11.17 s. The 0.50 s gap represents roughly 28 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Roma continues to build its lead. At 600 metres, it runs at 256 km/h versus 232 km/h. At 1,000 metres, the Roma finishes in 18.88 s versus 20.31 s, with a 1.43 s lead.
What the numbers don’t tell you
Electronically capped at 249 km/h, the Model S P85D never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 4.75 seconds. The 0.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Tesla Model S P85D is slightly faster than the Ferrari Roma to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
