Off the line, the i4 M50 xDrive hits 100 km/h in 3.92 s versus 4.68 s for the 545e xDrive. At this point, the i4 M50 xDrive leads by 0.75 s and sits roughly 5 m ahead.
At 200 metres, the i4 M50 xDrive is doing 155 km/h against 143 km/h for the 545e xDrive. The gap is 0.57 s. The challenger starts to claw back ground.
At 400 metres standing start, the i4 M50 xDrive crosses the line in 12.01 s versus 12.91 s. The 0.91 s gap represents roughly 44 m of track - a gap visible to the naked eye.
Past 400 metres, the i4 M50 xDrive continues to build its lead. At 600 metres, it runs at 216 km/h versus 200 km/h. At 1,000 metres, the i4 M50 xDrive finishes in 21.97 s versus 23.40 s, with a 1.43 s lead. Despite a higher top speed (250 (i.e. 155 mph - industry threshold) km/h), the 545e xDrive never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the i4 M50 xDrive is capped at 225 km/h, the 545e xDrive at 250 (i.e. 155 mph - industry threshold) 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 (4.07 kg/hp vs 4.94 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.16 seconds. The 0.75 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, i4 M50 xDrive G26 wins (3,92 s vs 4,67 s).
i4 M50 xDrive G26 goes from 0 to 100 km/h in 3,92 seconds (calibrated simulation).
