BMW X3 M40d G01 vs DS DS7 E-Tense 4x4 300: which is truly faster?

Off the line, the Bmw X3 M40d hits 100 km/h in 4.99 s versus 5.98 s for the DS7 E-Tense 4x4 300. Despite lacking instant torque, 340 hp of power compensates. At this point, the Bmw X3 M40d leads by 0.99 s and sits roughly 7 m ahead.

At 200 metres, the Bmw X3 M40d is doing 137 km/h against 127 km/h for the DS7 E-Tense 4x4 300. The gap is 0.55 s. The challenger starts to claw back ground.

At 400 metres standing start, the Bmw X3 M40d crosses the line in 13.34 s versus 14.27 s. The 0.93 s gap represents roughly 40 m of track — a gap visible to the naked eye.

Past 400 metres, the Bmw X3 M40d continues to build its lead. At 600 metres, it runs at 189 km/h versus 174 km/h. At 1,000 metres, the Bmw X3 M40d finishes in 24.47 s versus 26.41 s, with a 1.94 s lead.

Electronically capped at 250 (i.e. 155 mph — industry threshold) km/h, the Bmw X3 M40d never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

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 9.63 seconds. The 0.99 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
