The start: 0 to 100 km/h

Off the line, the 320d xDrive hits 100 km/h in 6.97 s versus 7.23 s for the Born. Despite lacking instant torque, 190 hp of power compensates. At this point, the 320d xDrive leads by 0.26 s and sits roughly 13 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 320d xDrive is doing 119 km/h against 122 km/h for the Born. The gap is 0.41 s. The gap widens compared to the 0-100.

At 400 metres standing start, the 320d xDrive crosses the line in 15.09 s versus 15.39 s. The 0.30 s gap represents roughly 13 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 320d xDrive continues to build its lead. At 600 metres, it runs at 165 km/h versus 160 km/h. At 1,000 metres, the 320d xDrive finishes in 27.84 s versus 28.98 s, with a 1.14 s lead.

What the numbers don’t tell you

The 320d xDrive features all-wheel drive (AWD) against the Born’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the Born is capped at 160 km/h, the 320d xDrive at 233 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

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 11.52 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
