The start: 0 to 100 km/h

Off the line, the 840d xDrive hits 100 km/h in 4.73 s versus 7.04 s for the 220i Gran Coupe. At this point, the 840d xDrive leads by 2.31 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 840d xDrive is doing 142 km/h against 122 km/h for the 220i Gran Coupe. The gap is 1.37 s. The challenger starts to claw back ground.

At 400 metres standing start, the 840d xDrive crosses the line in 13.00 s versus 15.11 s. The 2.12 s gap represents roughly 86 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 840d xDrive continues to build its lead. At 600 metres, it runs at 198 km/h versus 171 km/h. At 1,000 metres, the 840d xDrive finishes in 23.58 s versus 27.42 s, with a 3.84 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 840d xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 220i Gran Coupe at 238 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.63 kg/hp vs 8.03 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.19 seconds. The 2.31 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
