Off the line, the 840i Convertible hits 100 km/h in 5.36 s versus 6.47 s for the 530i. At this point, the 840i Convertible leads by 1.11 s and sits roughly 14 m ahead.
At 200 metres, the 840i Convertible is doing 137 km/h against 130 km/h for the 530i. The gap is 0.77 s. The challenger starts to claw back ground.
At 400 metres standing start, the 840i Convertible crosses the line in 13.59 s versus 14.61 s. The 1.02 s gap represents roughly 45 m of track - a gap visible to the naked eye.
Past 400 metres, the 840i Convertible continues to build its lead. At 600 metres, it runs at 191 km/h versus 183 km/h. At 1,000 metres, the 840i Convertible finishes in 24.56 s versus 26.09 s, with a 1.54 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 840i Convertible and the 530i 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 (5.38 kg/hp vs 6.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.76 seconds. The 1.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840i Convertible G15 wins (5,36 s vs 6,47 s).
840i Convertible G15 goes from 0 to 100 km/h in 5,36 seconds (calibrated simulation).
