Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 7.74 s for the 420i xDrive. At this point, the 911 GT3 leads by 3.67 s and sits roughly 17 m ahead.
At 200 metres, the 911 GT3 is doing 158 km/h against 115 km/h for the 420i xDrive. The gap is 2.20 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 15.61 s. The 3.75 s gap represents roughly 140 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 160 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 28.71 s, with a 7.48 s lead.
Electronically capped at 238 km/h, the 420i xDrive 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 (3.16 kg/hp vs 8.64 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.85 seconds. The 3.67 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 7,74 s).
911 GT3 991.1 goes from 0 to 100 km/h in 4,08 seconds (calibrated simulation).
