Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 5.52 s for the Cayman. At this point, the 911 GT3 leads by 1.44 s and sits roughly 13 m ahead.
At 200 metres, the 911 GT3 is doing 158 km/h against 136 km/h for the Cayman. The gap is 1.12 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 13.64 s. The 1.78 s gap represents roughly 82 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 190 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 24.68 s, with a 3.45 s lead.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.16 kg/hp vs 4.70 kg/hp) and transmission (Manual vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.30 seconds. The 1.44 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 5,52 s).
