The start: 0 to 100 km/h

Off the line, the M550i xDrive hits 100 km/h in 3.76 s versus 4.67 s for the M240i. At this point, the M550i xDrive leads by 0.91 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M550i xDrive is doing 160 km/h against 147 km/h for the M240i. The gap is 0.75 s. The challenger starts to claw back ground.

At 400 metres standing start, the M550i xDrive crosses the line in 11.67 s versus 12.78 s. The 1.10 s gap represents roughly 55 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M550i xDrive continues to build its lead. At 600 metres, it runs at 225 km/h versus 205 km/h. At 1,000 metres, the M550i xDrive finishes in 21.03 s versus 23.03 s, with a 2.00 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.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the M550i xDrive and the M240i 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 (3.61 kg/hp vs 4.49 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.84 seconds. The 0.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
