CONFIDENCE 96%The 2019 911 reaches 100 km/h first (3.08 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 2019 911 GT3 RS 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 0.09 s.

Roma vs 2019 911 GT3 RS: chronicle of a drag race at 357 km/h
The launch: 0 to 100 km/h
Off the line, the 2019 911 GT3 RS hits 100 km/h in 3.08 s versus 3.43 s for the Roma. At this point, the 2019 911 GT3 RS leads by 0.35 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 2019 911 GT3 RS is doing 173 km/h against 182 km/h for the Roma. The gap is 0.12 s. The challenger starts to claw back ground.
At 400 metres standing start, the Roma crosses the line in 10.68 s versus 10.77 s. The 0.09 s gap represents roughly 5 m of track — barely a car length.
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 238 km/h. At 1,000 metres, the Roma finishes in 18.88 s versus 19.59 s, with a 0.72 s lead.
What the numbers don’t tell you
With two combustion powertrains, the difference comes down to power-to-weight ratio (2.37 kg/hp vs 2.71 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 0.35 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 2019 911 GT3 RS 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.
