BMW X1 sDrive20d F48 vs BMW X3 xDrive20d G01: which is truly faster?

Off the line, the X1 sDrive20d hits 100 km/h in 7.80 s versus 7.92 s for the X3 xDrive20d. Despite the faster sprint time, the X3 xDrive20d is 12 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

At 200 metres, the X3 xDrive20d is doing 114 km/h against 119 km/h for the X1 sDrive20d. The gap is 0.32 s. The gap widens compared to the 0-100.

At 400 metres standing start, the X3 xDrive20d crosses the line in 15.76 s versus 15.77 s. The 0.01 s gap represents roughly 0 m of track

Past 400 metres, the situation changes. The X3 xDrive20d maxes out at 213 km/h while the X1 sDrive20d keeps accelerating towards 222 km/h. At 600 metres, the gap has dropped to 0.27 s.

Around 406 metres, both vehicles are level. This is the inversion point: the X1 sDrive20d overcomes its launch deficit thanks to a 9 km/h higher top speed.

At 1,000 metres, the X1 sDrive20d finishes in 28.46 s versus 29.22 s. The 0.76 s delta in favour of the X1 sDrive20d shows that top speed makes a clear difference.

Both rivals are electronically governed, but not at the same level: the X1 sDrive20d is capped at 222 km/h, the X3 xDrive20d at 213 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.

With two combustion powertrains, the difference comes down to power-to-weight ratio (8.11 kg/hp vs 9.66 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.46 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
