Off the line, the 840i Convertible hits 100 km/h in 5.57 s versus 7.07 s for the Q7 SUV. The 1.50 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 840i Convertible is doing 136 km/h against 117 km/h for the Q7 SUV. The gap is 0.55 s. The challenger starts to claw back ground.
At 400 metres standing start, the 840i Convertible crosses the line in 13.79 s versus 15.11 s. The 1.32 s gap represents roughly 52 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 190 km/h versus 162 km/h. At 1,000 metres, the 840i Convertible finishes in 24.82 s versus 28.09 s, with a 3.27 s lead.
Both rivals are electronically governed, but not at the same level: the 840i Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Q7 SUV at 226 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 (5.53 kg/hp vs 9.09 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.95 seconds. The 1.50 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 (5,57 s vs 7,07 s).
840i Convertible G15 goes from 0 to 100 km/h in 5,57 seconds (calibrated simulation).
