Off the line, the Bmw M4 Coupe hits 100 km/h in 4.38 s versus 7.15 s for the Bmw 120d. At this point, the Bmw M4 Coupe leads by 2.78 s and sits roughly 21 m ahead.
At 200 metres, the Bmw M4 Coupe is doing 157 km/h against 124 km/h for the Bmw 120d. The gap is 1.99 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M4 Coupe crosses the line in 12.21 s versus 15.30 s. The 3.09 s gap represents roughly 125 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M4 Coupe continues to build its lead. At 600 metres, it runs at 221 km/h versus 172 km/h. At 1,000 metres, the Bmw M4 Coupe finishes in 21.75 s versus 27.53 s, with a 5.78 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw M4 Coupe is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 120d at 228 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 (3.64 kg/hp vs 7.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.99 seconds. The 2.78 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Coupe F82 wins (4,38 s vs 7,15 s).
M4 Coupe F82 goes from 0 to 100 km/h in 4,38 seconds (calibrated simulation).
