The start: 0 to 100 km/h

Off the line, the 118i hits 100 km/h in 8.56 s versus 8.62 s for the 118d xDrive. The 0.06 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 118d xDrive is doing 112 km/h against 112 km/h for the 118i. The gap is 0.11 s. The gap remains stable from the start.

At 400 metres standing start, the 118d xDrive crosses the line in 16.28 s versus 16.36 s. The 0.08 s gap represents roughly 3 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.12 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 118d xDrive and the 118i are governed to 210 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.

With two combustion powertrains, the difference comes down to power-to-weight ratio (9.80 kg/hp vs 9.56 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.20 seconds. The 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
