The start: 0 to 100 km/h

Off the line, the 740d xDrive hits 100 km/h in 5.09 s versus 5.32 s for the 740Le xDrive iPerformance. Despite lacking instant torque, 340 hp of power compensates. The 0.23 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 740d xDrive is doing 137 km/h against 134 km/h for the 740Le xDrive iPerformance. The gap is 0.06 s. The challenger starts to claw back ground.

At 400 metres standing start, the 740d xDrive crosses the line in 13.37 s versus 13.54 s. The 0.17 s gap represents roughly 8 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 740d xDrive continues to build its lead. At 600 metres, it runs at 191 km/h versus 188 km/h. At 1,000 metres, the 740d xDrive finishes in 24.34 s versus 24.72 s, with a 0.38 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.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 740d xDrive and the 740Le xDrive iPerformance 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.34 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
