Off the line, the 911 R hits 100 km/h in 3.78 s versus 3.95 s for the Cayman GT4. Despite the faster sprint time, the Cayman GT4 is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 911 R is doing 166 km/h against 155 km/h for the Cayman GT4. The gap is 0.19 s. The gap remains stable from the start.
At 400 metres standing start, the 911 R crosses the line in 11.38 s versus 11.90 s. The 0.52 s gap represents roughly 28 m of track - two to three car lengths.
Past 400 metres, the 911 R continues to build its lead. At 600 metres, it runs at 239 km/h versus 218 km/h. At 1,000 metres, the 911 R finishes in 20.19 s versus 21.59 s, with a 1.40 s lead.
With two combustion powertrains, the difference comes down to power-to-weight ratio (2.74 kg/hp vs 3.48 kg/hp) and transmission (Manual vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.92 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 R 991.2 wins (3,78 s vs 3,95 s).
911 R 991.2 goes from 0 to 100 km/h in 3,78 seconds (calibrated simulation).
