Off the line, the M550d xDrive Touring hits 100 km/h in 4.56 s versus 4.95 s for the 840i. At this point, the M550d xDrive Touring leads by 0.40 s and sits roughly 6 m ahead.
At 200 metres, the M550d xDrive Touring is doing 144 km/h against 142 km/h for the 840i. The gap is 0.29 s. The challenger starts to claw back ground.
At 400 metres standing start, the M550d xDrive Touring crosses the line in 12.82 s versus 13.15 s. The 0.33 s gap represents roughly 16 m of track - two to three car lengths.
Past 400 metres, the M550d xDrive Touring continues to build its lead. At 600 metres, it runs at 200 km/h versus 198 km/h. At 1,000 metres, the M550d xDrive Touring finishes in 23.33 s versus 23.75 s, with a 0.42 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the M550d xDrive Touring and the 840i are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.89 kg/hp vs 5.03 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.46 seconds. The 0.40 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M550d xDrive Touring G30 wins (4,55 s vs 4,95 s).
M550d xDrive Touring G30 goes from 0 to 100 km/h in 4,55 seconds (calibrated simulation).
