The start: 0 to 100 km/h

Off the line, the X1 sDrive20d hits 100 km/h in 7.80 s versus 8.36 s for the 9 E-Tense 250. Despite lacking instant torque, 190 hp of power compensates. At this point, the X1 sDrive20d leads by 0.56 s and sits roughly 15 m ahead.

From 100 km/h to 400 metres

At 200 metres, the X1 sDrive20d is doing 119 km/h against 121 km/h for the 9 E-Tense 250. The gap is 0.54 s. The gap remains stable from the start.

At 400 metres standing start, the X1 sDrive20d crosses the line in 15.77 s versus 16.22 s. The 0.45 s gap represents roughly 19 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The X1 sDrive20d maxes out at 222 km/h while the 9 E-Tense 250 keeps accelerating towards 235 km/h. At 600 metres, the gap is down to 0.34 s from 0.45 s at 400 metres.

At 1,000 metres, the X1 sDrive20d finishes in 28.46 s versus 28.57 s, with just 0.10 s to spare. The 9 E-Tense 250 fails to fully close the launch gap.

What the numbers don’t tell you

Electronically capped at 222 km/h, the X1 sDrive20d 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 12.32 seconds. The 0.56 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
