The start: 0 to 100 km/h

Off the line, the 911 Turbo S hits 100 km/h in 2.53 s versus 3.43 s for the Roma. At this point, the 911 Turbo S leads by 0.90 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Turbo S is doing 185 km/h against 182 km/h for the Roma. The gap is 0.66 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Turbo S crosses the line in 10.00 s versus 10.68 s. The 0.67 s gap represents roughly 42 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Turbo S continues to build its lead. At 600 metres, it runs at 257 km/h versus 256 km/h. At 1,000 metres, the 911 Turbo S finishes in 18.17 s versus 18.88 s, with a 0.71 s lead. Despite a higher top speed (357 km/h), the Roma never recovers its launch deficit.

What the numbers don’t tell you

Electronically capped at 322 (i.e. 200 mph - industry threshold) km/h, the 911 Turbo S 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 (2.43 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 4.54 seconds. The 0.90 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
