Off the line, the Bmw M850i xDrive Gran Coupe hits 100 km/h in 3.97 s versus 4.55 s for the Bmw Z4 M40i. At this point, the Bmw M850i xDrive Gran Coupe leads by 0.58 s and sits roughly 6 m ahead.
At 200 metres, the Bmw M850i xDrive Gran Coupe is doing 158 km/h against 147 km/h for the Bmw Z4 M40i. The gap is 0.52 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M850i xDrive Gran Coupe crosses the line in 11.88 s versus 12.71 s. The 0.84 s gap represents roughly 42 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw M850i xDrive Gran Coupe continues to build its lead. At 600 metres, it runs at 221 km/h versus 204 km/h. At 1,000 metres, the Bmw M850i xDrive Gran Coupe finishes in 21.37 s versus 23.00 s, with a 1.63 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 Bmw M850i xDrive Gran Coupe and the Bmw Z4 M40i 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 (3.79 kg/hp vs 4.57 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.79 seconds. The 0.58 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.
