Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 7.44 s for the Bmw 420i. At this point, the 911 GT3 leads by 3.37 s and sits roughly 17 m ahead.
At 200 metres, the 911 GT3 is doing 158 km/h against 117 km/h for the Bmw 420i. The gap is 2.09 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 15.38 s. The 3.53 s gap represents roughly 135 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 163 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 28.23 s, with a 6.99 s lead.
Electronically capped at 240 km/h, the Bmw 420i 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 8.29 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 3.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
