The start: 0 to 100 km/h

Off the line, the Bmw M5 Competition hits 100 km/h in 3.34 s versus 4.32 s for the Bmw M340i xDrive. At this point, the Bmw M5 Competition leads by 0.98 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Bmw M5 Competition is doing 166 km/h against 147 km/h for the Bmw M340i xDrive. The gap is 0.80 s. The challenger starts to claw back ground.

At 400 metres standing start, the Bmw M5 Competition crosses the line in 11.16 s versus 12.46 s. The 1.30 s gap represents roughly 64 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Bmw M5 Competition continues to build its lead. At 600 metres, it runs at 232 km/h versus 206 km/h. At 1,000 metres, the Bmw M5 Competition finishes in 20.32 s versus 22.65 s, with a 2.33 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 Bmw M5 Competition and the Bmw M340i xDrive 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 (3.03 kg/hp vs 4.77 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.58 seconds. The 0.98 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
