Off the line, the M4 Competition Coupe hits 100 km/h in 4.17 s versus 5.14 s for the 840i. At this point, the M4 Competition Coupe leads by 0.97 s and sits roughly 9 m ahead.
At 200 metres, the M4 Competition Coupe is doing 154 km/h against 140 km/h for the 840i. The gap is 0.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the M4 Competition Coupe crosses the line in 12.15 s versus 13.35 s. The 1.20 s gap represents roughly 57 m of track - a gap visible to the naked eye.
Past 400 metres, the M4 Competition Coupe continues to build its lead. At 600 metres, it runs at 216 km/h versus 195 km/h. At 1,000 metres, the M4 Competition Coupe finishes in 21.87 s versus 24.12 s, with a 2.24 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the M4 Competition Coupe and the 840i are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.49 kg/hp vs 5.20 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.77 seconds. The 0.97 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Competition Coupe F82 wins (4,17 s vs 5,14 s).
M4 Competition Coupe F82 goes from 0 to 100 km/h in 4,17 seconds (calibrated simulation).
