Off the line, the 630i Gran Turismo hits 100 km/h in 6.57 s versus 6.83 s for the 320d. Despite the faster sprint time, the 320d is 8 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 320d is doing 120 km/h against 127 km/h for the 630i Gran Turismo. The gap is 0.12 s. The challenger starts to claw back ground.
At 400 metres standing start, the 630i Gran Turismo crosses the line in 14.75 s versus 14.95 s. The 0.21 s gap represents roughly 8 m of track - barely a car length.
Past 400 metres, the 630i Gran Turismo continues to build its lead. At 600 metres, it runs at 178 km/h versus 166 km/h. At 1,000 metres, the 630i Gran Turismo finishes in 26.53 s versus 27.60 s, with a 1.06 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 630i Gran Turismo 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 (6.92 kg/hp vs 8.11 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.30 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 630i Gran Turismo G32 wins (6,57 s vs 6,83 s).
630i Gran Turismo G32 goes from 0 to 100 km/h in 6,57 seconds (calibrated simulation).
