Off the line, the Bmw 320i xDrive hits 100 km/h in 7.51 s versus 8.00 s for the S60 B4. At this point, the Bmw 320i xDrive leads by 0.49 s and sits roughly 7 m ahead.
At 200 metres, the Bmw 320i xDrive is doing 117 km/h against 115 km/h for the S60 B4. The gap is 0.29 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 320i xDrive crosses the line in 15.47 s versus 15.82 s. The 0.35 s gap represents roughly 14 m of track — two to three car lengths.
Past 400 metres, the Bmw 320i xDrive continues to build its lead. At 600 metres, it runs at 162 km/h versus 161 km/h. At 1,000 metres, the Bmw 320i xDrive finishes in 28.46 s versus 28.87 s, with a 0.41 s lead.
The Bmw 320i xDrive features all-wheel drive (AWD) against the S60 B4’s FWD. 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 S60 B4 is capped at 180 km/h, the Bmw 320i xDrive at 230 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 (8.27 kg/hp vs 8.37 kg/hp) and transmission (auto vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.00 seconds. The 0.49 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
