The start: 0 to 100 km/h

Off the line, the 545e xDrive hits 100 km/h in 4.68 s versus 6.08 s for the i4 eDrive35. At this point, the 545e xDrive leads by 1.41 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 545e xDrive is doing 143 km/h against 131 km/h for the i4 eDrive35. The gap is 1.03 s. The challenger starts to claw back ground.

At 400 metres standing start, the 545e xDrive crosses the line in 12.91 s versus 14.38 s. The 1.46 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 545e xDrive continues to build its lead. At 600 metres, it runs at 200 km/h versus 179 km/h. At 1,000 metres, the 545e xDrive finishes in 23.40 s versus 26.26 s, with a 2.86 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 545e xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the i4 eDrive35 at 190 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (4.94 kg/hp vs 6.99 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.27 seconds. The 1.41 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
