Race simulation at real speed
CONFIDENCE 95%The Panamera Turbo reaches 100 km/h first (3.37 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 Porsche Panamera Turbo S E-Hybrid 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 0.63 s.

Panamera Turbo S E-Hybrid vs Roma: chronicle of a drag race at 357 km/h
The launch: 0 to 100 km/h
Off the line, the Panamera Turbo S E-Hybrid hits 100 km/h in 3.37 s versus 3.43 s for the Roma. The 0.06 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Roma is doing 182 km/h against 163 km/h for the Panamera Turbo S E-Hybrid. The gap is 0.20 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Roma crosses the line in 10.68 s versus 11.31 s. The 0.63 s gap represents roughly 35 m of track — a gap visible to the naked eye.
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 228 km/h. At 1,000 metres, the Roma finishes in 18.88 s versus 20.50 s, with a 1.62 s lead.
What the numbers don’t tell you
Electronically capped at 310 km/h, the Panamera Turbo S E-Hybrid 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.38 kg/hp vs 2.37 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.02 seconds. The 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Panamera Turbo S E-Hybrid and Ferrari Roma are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
