The start: 0 to 100 km/h

Off the line, the 330d xDrive Touring hits 100 km/h in 5.31 s versus 7.03 s for the 320d. At this point, the 330d xDrive Touring leads by 1.73 s and sits roughly 21 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 330d xDrive Touring is doing 133 km/h against 123 km/h for the 320d. The gap is 1.14 s. The challenger starts to claw back ground.

At 400 metres standing start, the 330d xDrive Touring crosses the line in 13.64 s versus 15.13 s. The 1.49 s gap represents roughly 62 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 330d xDrive Touring continues to build its lead. At 600 metres, it runs at 185 km/h versus 173 km/h. At 1,000 metres, the 330d xDrive Touring finishes in 24.99 s versus 27.23 s, with a 2.24 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 330d xDrive Touring is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 320d at 240 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 (6.58 kg/hp vs 7.63 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.96 seconds. The 1.73 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
