The start: 0 to 100 km/h

Off the line, the 320d xDrive Touring hits 100 km/h in 7.44 s versus 9.13 s for the 318d. At this point, the 320d xDrive Touring leads by 1.69 s and sits roughly 11 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 320d xDrive Touring is doing 117 km/h against 109 km/h for the 318d. The gap is 0.65 s. The challenger starts to claw back ground.

At 400 metres standing start, the 320d xDrive Touring crosses the line in 15.48 s versus 16.56 s. The 1.08 s gap represents roughly 40 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 320d xDrive Touring continues to build its lead. At 600 metres, it runs at 163 km/h versus 151 km/h. At 1,000 metres, the 320d xDrive Touring finishes in 28.40 s versus 30.51 s, with a 2.11 s lead.

What the numbers don’t tell you

The 320d xDrive Touring features all-wheel drive (AWD) against the 318d’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 320d xDrive Touring is capped at 225 km/h, the 318d at 210 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 (8.89 kg/hp vs 10.45 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.33 seconds. The 1.69 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
