Off the line, the Bmw M4 Coupe hits 100 km/h in 4.38 s versus 7.74 s for the Bmw 420i xDrive. At this point, the Bmw M4 Coupe leads by 3.37 s and sits roughly 12 m ahead.
At 200 metres, the Bmw M4 Coupe is doing 157 km/h against 115 km/h for the Bmw 420i xDrive. The gap is 1.87 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 15.61 s. The 3.39 s gap represents roughly 127 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 160 km/h. At 1,000 metres, the Bmw M4 Coupe finishes in 21.75 s versus 28.71 s, with a 6.96 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 420i xDrive at 238 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 8.64 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.85 seconds. The 3.37 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 7,74 s).
