Off the line, the 812 Superfast hits 100 km/h in 2.93 s versus 7.74 s for the 420i xDrive. At this point, the 812 Superfast leads by 4.81 s and sits roughly 17 m ahead.
At 200 metres, the 812 Superfast is doing 182 km/h against 115 km/h for the 420i xDrive. The gap is 3.21 s. The challenger starts to claw back ground.
At 400 metres standing start, the 812 Superfast crosses the line in 10.37 s versus 15.61 s. The 5.23 s gap represents roughly 190 m of track - a gap visible to the naked eye.
Past 400 metres, the 812 Superfast continues to build its lead. At 600 metres, it runs at 249 km/h versus 160 km/h. At 1,000 metres, the 812 Superfast finishes in 18.81 s versus 28.71 s, with a 9.90 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 (1.91 kg/hp vs 8.64 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.85 seconds. The 4.81 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 812 Superfast wins (2,93 s vs 7,74 s).
