BMW X6 xDrive40i G06 vs DS7 E-Tense 4x4 300: which is truly faster?

Off the line, the X6 xDrive40i hits 100 km/h in 5.67 s versus 5.98 s for the 7 E-Tense 4x4 300. Despite lacking instant torque, 333 hp of power compensates. The 0.31 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the X6 xDrive40i is doing 132 km/h against 127 km/h for the 7 E-Tense 4x4 300. The gap is 0.12 s. The challenger starts to claw back ground.

At 400 metres standing start, the X6 xDrive40i crosses the line in 13.94 s versus 14.27 s. The 0.33 s gap represents roughly 14 m of track - two to three car lengths.

Past 400 metres, the X6 xDrive40i continues to build its lead. At 600 metres, it runs at 182 km/h versus 174 km/h. At 1,000 metres, the X6 xDrive40i finishes in 25.47 s versus 26.41 s, with a 0.94 s lead.

Electronically capped at 248 km/h, the X6 xDrive40i 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 0.31 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
