Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 4.90 s for the Cayman S. At this point, the 911 GT3 leads by 0.82 s and sits roughly 11 m ahead.
At 200 metres, the 911 GT3 is doing 158 km/h against 147 km/h for the Cayman S. The gap is 0.72 s. The gap remains stable from the start.
At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 12.90 s. The 1.05 s gap represents roughly 52 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 GT3 continues to build its lead. At 600 metres, it runs at 225 km/h versus 205 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 23.17 s, with a 1.94 s lead.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.16 kg/hp vs 4.00 kg/hp) and transmission (Manual vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.04 seconds. The 0.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 GT3 991.1 wins (4,08 s vs 4,89 s).
911 GT3 991.1 goes from 0 to 100 km/h in 4,08 seconds (calibrated simulation).
