Off the line, the M2 hits 100 km/h in 4.12 s versus 5.40 s for the Bmw 840i Convertible. At this point, the M2 leads by 1.29 s and sits roughly 10 m ahead.
At 200 metres, the M2 is doing 155 km/h against 136 km/h for the Bmw 840i Convertible. The gap is 0.98 s. The challenger starts to claw back ground.
At 400 metres standing start, the M2 crosses the line in 12.08 s versus 13.63 s. The 1.55 s gap represents roughly 71 m of track — a gap visible to the naked eye.
Past 400 metres, the M2 continues to build its lead. At 600 metres, it runs at 215 km/h versus 191 km/h. At 1,000 metres, the M2 finishes in 21.80 s versus 24.62 s, with a 2.82 s lead.
Both rivals are electronically governed, but not at the same level: the M2 is capped at 285 km/h, the Bmw 840i Convertible 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 combustion powertrains, the difference comes down to power-to-weight ratio (3.76 kg/hp vs 5.53 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.24 seconds. The 1.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
