Off the line, the 520d Touring hits 100 km/h in 7.47 s versus 7.55 s for the 320d Touring. The 0.08 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 520d Touring is doing 115 km/h against 121 km/h for the 320d Touring. The gap is 0.45 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 520d Touring crosses the line in 15.42 s versus 15.61 s. The 0.19 s gap represents roughly 8 m of track - barely a car length.
Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 225 km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 225 km/h.
At 1,000 metres, the 320d Touring finishes in 28.17 s versus 28.59 s. The 0.42 s delta shows an extremely tight race.
Both rivals are electronically governed, but not at the same level: the 320d Touring is capped at 229 km/h, the 520d Touring at 225 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 (8.24 kg/hp vs 9.16 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.58 seconds. The 0.08 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.
Over 0–100 km/h, 320d Touring G20 and 520d Touring G30 are neck and neck (7,47 s vs 7,55 s, no significant gap).
320d Touring G20 goes from 0 to 100 km/h in 7,55 seconds (calibrated simulation).
320d Touring G20: 190 hp, ratio 8,24 kg/hp. 520d Touring G30: 190 hp, ratio 9,16 kg/hp.
320d Touring G20: 229 km/h. 520d Touring G30: 225 km/h.
