The start: 0 to 100 km/h

Off the line, the 911 GT3 RS hits 100 km/h in 3.85 s versus 4.12 s for the M2. At this point, the 911 GT3 RS leads by 0.26 s and sits roughly 3 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 GT3 RS is doing 164 km/h against 155 km/h for the M2. The gap is 0.28 s. The gap remains stable from the start.

At 400 metres standing start, the 911 GT3 RS crosses the line in 11.57 s versus 12.08 s. The 0.51 s gap represents roughly 27 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 GT3 RS continues to build its lead. At 600 metres, it runs at 232 km/h versus 215 km/h. At 1,000 metres, the 911 GT3 RS finishes in 20.63 s versus 21.80 s, with a 1.17 s lead.

What the numbers don’t tell you

Electronically capped at 285 km/h, the M2 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 (2.74 kg/hp vs 3.76 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.94 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
