Off the line, the M340i xDrive hits 100 km/h in 4.32 s versus 5.91 s for the 730d xDrive. At this point, the M340i xDrive leads by 1.59 s and sits roughly 13 m ahead.
At 200 metres, the M340i xDrive is doing 147 km/h against 128 km/h for the 730d xDrive. The gap is 1.08 s. The challenger starts to claw back ground.
At 400 metres standing start, the M340i xDrive crosses the line in 12.46 s versus 14.19 s. The 1.72 s gap represents roughly 74 m of track - a gap visible to the naked eye.
Past 400 metres, the M340i xDrive continues to build its lead. At 600 metres, it runs at 206 km/h versus 178 km/h. At 1,000 metres, the M340i xDrive finishes in 22.65 s versus 25.95 s, with a 3.30 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 M340i xDrive and the 730d xDrive 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 (4.77 kg/hp vs 6.96 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.48 seconds. The 1.59 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.
